PREFACE 

Mr. Hans Bjørn, chairman DBDH 

Denmark gained the world’s attention when global warming 

was at the agenda during the global climate summit (cop15) 

in copenhagen in December, 2009. After several climate-marathon 

meetings, the ‘copenhagen Accord’ was announced on 19 

December. these meetings demonstrated how far it was possible 

to reach with the long-term global challenges, and for the first 

time in history, the world leaders agreed that the global temperature 

should not exceed more than 2 degrees celsius. Furthermore 

the leaders shared the same opinion about taking the necessary 

precautions to achieve the principle about “a common and differentiated 

responsibility”. 

From 2-4 november 2009, DBDH was the co-organizer of the 

first true international summit on District energy solutions. the 

summit was arranged together with the international District 

energy Association, euroheat and power, Danish District Heating 

Association and endorsed by the international energy Agency. the 

conference’s title was ‘leading the way to copenhagen’ thereby 

acting as the precursor to the cop 15 event. A significant output 

of the event was recommendations to cop15 to take good note 

of a technology that is proven, flexible and reliable, convenient to 

use, and highly cost effective in combating climate change. 

the role of the district heating sector in the Danish climate action 

was also on the agenda in november, when DBDH had audience with 

the Danish parliament’s energy committee. energy technology is 

the sector with the fastest growing export in Denmark and the 

Danish district heating industry is contributing to this growth. 

the export sales of district heating technology have doubled in 

five years, and as a technology, district heating can be used for 

cooling as well. this brings along new opportunities. However, there 

is a need for continued and additional political support to push 

forward new energy solutions like district cooling in Denmark. 

For the first time ever, the Danish district heating industry has 

been analyzed in a report by the same name: “the district heating 

industry 2008”. the publication made the front page article 

in the largest Danish Business paper; Børsen, with the headline: 

“Boom in exports of District energy.” please read more about 

the report at page 6. 

in these years, the greater cities of Denmark, including 

copenhagen and Aarhus, are working on new coherent municipal 

Heat plans for the future demand and supply of district heating. 

But the background of the heat plans varies from city to city. 

However, a common feature is the changed framework for the 

D B D H | A n n u A l R e p o R t 2 0 0 9 

sector of heating and electricity, and the huge environmental and 

economic challenges that the heating sector is facing. 

today, the future of the heat-supply is being evaluated in a cli- 

mate context with several cities working toward the same goal 

of becoming co2-neutral. similarly, new renewable energies and 

technologies are on the agenda. For instance geothermal energy, 

solar heating and heat pumps which are exploiting heat from 

various sources to be integrated into the system. the purpose 

of the heat plans are to give companies and government a solid 

background to ensure a sensible heat price and energy efficiency 

while at the same time, maintaining the security of supply and 

reducing the co2 emissions in order to benefit both society and 

heat customers. 

As part of our latest media concept you can watch a newly 

produced video “Just imagine”, which maps District energy and 

combined Heat and power in Denmark. you are welcome to request 

the DVD from DBDH or find it on youtube. 

DBDH is still publishing the quarterly technical journal “Hot|cool”, 

which is free of charge and issued to about 7.000 readers in more 

than 50 countries. the journal can also be read in an online version 

at www.dbdh.dk which makes it possible to make pDF copies of an 

article directly from the website. 

in 2009, DBDH organized joint visits to a number of countries such 

as Hungary, russia, serbia, slovenia, spain, sweden, Mongolia and 

usA. DBDH and Danfoss had the pleasure to be specially invited 

to chicago with their royal Highnesses crown prince Frederik 

and crown princess Mary of Denmark addressing climate change 

with urban sustainability solutions. you can read more about the 

visit to chicago at page 18. 

1 January 2010, DBDH became a member of the confederation 

of Danish industries (Di). it is an epoch-making step for DBDH, 

who for more than 30 years has been working with the same 

business concept. 

A large majority of DBDH’s members voted for membership of Di in 

order to strengthen public affairs primarily towards the european 

union. it has been agreed that the synergies that will arise in close 

cooperation with the confederation’s political skills shall prepare 

and strengthen DBDH against any future challenges. we are very 

pleased to expand the cooperation with Di. 

DBDH wishes to thank all our partners within the district energy 

sector for a very interesting and active year – we appreciate the 

many invitations to participate at conferences in both Denmark 

and abroad, and we are looking forward to continuing the close 

cooperation and to jointly promote the knowledge and the advantages 

of District Hearing to the world.

REPoRt on thE dAnish 

distRiCt hEAting industRy 

in July 2009, cowi A/s made a 

report about the Danish District 

Heating industry that presents 

the role of district heating in the 

Danish society in terms of economy 

and environment. the report is 

mainly based on data from the 

Danish energy Agency and from 

a questionnaire survey among 

the companies within the district 

heating industry in the period 

January – April 2009. 

District heating industry 

in today’s Denmark 

over the years the district heating 

industry has grown steadily and today 

it is an increasingly important 

part of the Danes’ everyday lives. 

More than 60% of the houses in 

Denmark are heated with district 

heating and a substantial part 

of offices, shops and institutions 

benefit from the easy heat which 

most people don’t even notice. it’s 

just there! 

the Danish DH industry has an approximate turnover of 19 billion 

DKK (approx. 2.6 billion euros) and employs roughly 9000 people 

in Denmark who provide heat for 1.6 million households. the largest 

employment is found in companies supplying the necessary 

technology or in companies that export DH products and services. 

there is a large unexploited potential for Danish exports of DH 

technology. the potential in the biggest markets where Danish 

companies already are present is estimated to more than 50 

times of the total installed capacity in Denmark alone. so from an 

economic point of view, district heating has been profitable both 

nationally and individually and has created many jobs in Denmark 

Flexibility and self-sufficiency 

since 1997, Denmark has been self-sufficient with energy – today, 

as the only country in the eu. this self-sufficiency will gradually de- 


crease as the oil and gas reserves 

in the north sea are exhausted. the 

Danish energy Agency expects the 

self-sufficiency with oil and gas to 

end in 2016, when Denmark again will 

be net importer of oil and gas. 

without DH Denmark wouldn’t have 

been self-sufficient with oil and gas 

in 2008. DH exploits the surplus 

heat from the industry production 

and electricity production and is 

increasingly produced by domestic 

renewable sources such as biomass, 

waste and geothermal. it reduces 

the dependency on individual heating 

with oil and gas, and thus the 

dependency on importing fossil 

fuels. 

in 2008, the total Danish production 

of oil and gas was 974 pJ while the 

consumption was 869 pJ. without 

DH, this requirement would have 

been 990 pJ thus making Denmark 

net importer of energy. Denmark 

also produces renewable energy 

which helps to increase the Danish self-sufficiency. in Denmark it 

is the target to create fossil free energy. Besides the fact that 

it from a socioeconomic point of view is beneficial and provides a 

significant environmental benefit, it will also increase the security 

of supply when the Danish oil and gas reserves disappear. 

the Danish DH model provides one of the imminent solutions, because 

the system allows you to switch the type of fuel relative to 

what seems viable now and in the future. At the same time, district 

heating is a secure and stable form of heat supply. And last but not 

least, DH is a technology that makes money and, at the same time, 

is doing the best for the climate and the environment.

First members’ meeting of the year was held in the scenic area of 

Vejle at Hotel Haraldskær. some 40 member companies, partners 

and guests participated to hear more about “District cooling & 

the Middle east”. 

2 new member companies: Flowcon international and 

Amagerforbrænding began the meeting by presenting their 

companies to the participants. After this introduction, Birgitte 

rahbek, shared her deep knowledge of the Middle east spiced 

with many anecdotes from this part of the world. 

”District cooling in the Desert country” - thomas Bay, trade 

office in Dubai, presented the many market opportunities in the 

Dubai region being the centre for more than 2 billion consumers. 

later the audience also got an insight into the first big Danish 

reference project on district cooling: the Kongens nytorv project 

with 15 Mw of installed cooling. in future, hotels, shopping centers, 

restaurants, office buildings and shops around Kongens nytorv will 

be supplied by district cooling. Jan Don Høgh, copenhagen energy, 

presented the project and the future perspectives. A technical 

presentation was provided by Danish technological institute 

explaining the advantages and disadvantages of co2 as a means 

of cooling in large systems. 

charlotte Juul, Austrian Airlines, was the sponsor of the day. 

winner of the lucky draw was Michael Hansen from Kamstrup. 

Michael could look forward to a free flight to the Middle east.

Again this year, the DBDH general assembly was held at 

christiansborg, home to the Danish parliament. Venstre, the 

liberal party, hosted the meeting and the following members’ 

dinner took place in the famous Danish ”snapstinget”. this year’s 

general assembly also meant a goodbye to DBDH chairman for the 

past 6 years, lars gullev. new elected chairman was Hans Bjørn, 

Managing Director of tVis. Further members of the new board 

of directors were: tanja Kisliakova, Kamstrup; Jens ole Hansen, 

cowi; thomas rand, ramboll; Jens Dall, Dall energy, Helle Due, 

7-technologies; per t. christensen, ABB. 

A new point was on the agenda at the assembly: the election of 

“DBDH member of the year”. the honour went to the company 

Kamstrup, which in 2008 had proven to be the most active member 

of DBDH. Member of the board tanja Kisliakova and Knud 

Bonde, Division Director, received the diploma on behalf of the 

company. 

in conclusion of the general assembly, lars christian lilleholt, 

Member of parliament - and spokesperson of Venstre on climate 

and energy issues, gave a presentation about Danish and international 

energy politics, followed by a short but lively Q/A session.

“How district heating contributes to the vision of Denmark’s 

independence from fossil fuels” was the well timed theme for the 

June members’ meeting at Hotel sixtus in Middelfart. 

2 new members, iron puMp and nirAs presented their compa- 

nies to the participant, before peter Markussen, Dong energy, 

took the floor with an interesting presentation about how Dong 

expects to convert from today’s 85% fossil fuels and 15% renewable 

to the opposite. From uffe Jørgensen, university of Aarhus, 

the participants learned how much biomass, we actually have in 

Denmark and worldwide to be used for energy in a sustainable 

manner. Hereafter, per wulff, Vestforbrænding, told about the 

conversion from natural gas to co2-neutral fuels at Vestegnen. 

Hans Henrik lindboe from eA energianalyse shared the vision 

“Denmark free of fossil fuels” with the members and how to get 

to this point. A glimpse of the brave new world was given by Karin 

Høgh. she gave an interesting insight into the many existing social 

networks such as slideshare, linked in, Facebook, twitter and how 

to use them in a valuable manner. 

eva rasmussen, FiF Marketing, was sponsor of the meeting with 

many fine gifts. A district heating quiz settled the winners to be 

Birthe steffensen, iron pump, per Boysen, Danfoss, and søren 

Barkholt, Bwsc.

At the autumn meeting members went to Funen to gather at 

Hvedholm castle. ”the role of district heating in reduction of 

global warming” was the headline of the meeting. 

First speaker at the floor was lars ibsen from logstor who told 

the interesting story about the new climate strategy of logstor. 

Managing Director of DBDH, Jes B. christensen, continued with a 

presentation of the newly issued report ”District Heating industry 

2008”. A comprehensive report that has been prepared by cowi. 

However, district heating sometimes seems to be a well kept 

secret, which is why DBDH had invited Kresten schultz Jørgensen, 

leadAgency, to kick-start ideas for new ways of illustrating the 

good message. Members were divided into five different groups 

with the task to identify ”the value story of district heating” and 

to identify the top 3 priorities for district heating when it comes 

to reducing global warming. A good and very inspiring day for all 

participants of which the result were communicated to the Danish 

Minister for climate and energy, connie Hedegaard. 

in the lovely surroundings of the hotel, members enjoyed a good 

autumn menu for dinner, and - not least - some amusing and 

inspiring hours together with colleagues.

ClimAtE-FRiEndly distRiCt hEAting FoR thE FutuRE 

By Managing Director Mr. lars gullev, VeKs 

Heat plan greater copenhagen 

deals with the future dis- 

trict heating (DH) in greater 

copenhagen. the analysis has 

been initiated by the major 

DH companies in greater 

copenhagen - ctr, copenhagen 

energy and VeKs. 

this short article gives an 

overview of the results from 

the study and the next steps 

towards implementation. 

Focus on co2 AnD 

RenewABle eneRGy 

the future goals and framework for the 

development of the energy sector are set 

by decisions in eu as well as in the Danish 

parliament. eu has focus on the internal 

market for electricity and gas, increased 

utilisation of cHp as well as further 

development of the co2 quota market. 

objectives for co2 reduction have been 

stated; renewable energy (re) and savings 

in 2020 of each 20%. 

the big producers of electricity & heat, 

and the owners of waste incineration 

plants are interested in the heat markets 

and help define how the supply will develop. 

But it is the heat customers who may have 

to pay part of the bill in the heat price. 

it is therefore crucial that the heating 

companies get actively involved in the 

development of future solutions. 

on that background ctr, copenhagen 

energy and VeKs initiated the project 

Heat plan for greater copenhagen in 

2008 which was finalised summer 2009. 

the project sets up five scenarios for the 

future DH system in greater copenhagen. 

Four of these scenarios end in 2025, and 

the fifth, a ”perspective scenario”, continues 

to 2050. in each of these scenarios, 


the optimal economical dispatch of both 

power and heat production determines 

which plants and fuels are to be used 

within the existing frameworks of the 

specified energy policies and taxation. 

More than 70 % Renewable energy 

the analyses show that re can cover 

more than 70 % of DH demand in the metropolitan 

region from as early as 2015 – if 

the involved parties are willing to do what 

it takes. Furthermore the study shows 

that it can be achieved without negative 

economic consequences for the end users 

as well as the society. 

there are two main factors that make 

it possible: 

• First; there is a good scope for converting 

the fossil fuel at the existing 

large cHp plants to biomass. 

• second; there are opportunities for 

exploiting the increasing volumes of 

waste in highly efficient cHp incineration 

plants. 

However this presumes that taxes still 

favour biomass in terms of heat production, 

and that biomass based electricity 

production is still subsidised.

new fuels in play 

the scenario analyses show 

that the existing cHp plants can 

benefit from converting from 

coal to biomass - particulary 

wood pellets and wood chips - if 

total cost is the deciding factor. 

coal and natural gas will remain 

backup fuels for the security of 

supply until the biomass market 

is more developed. Biomass use 

in central cHp plants offers a 

way to rapidly and significantly 

increase the re percentage of 

DH within just 4-5 years. 

coal will not fade out entirely, but will still 

be competitive for condensing electricity 

production at the large cHp plants. when 

demand for heat decreases and electricity 

prices are high, some of the plants use 

coal for electricity generation only. 

Heat from waste incineration is the primary 

base load in relation to the overall 

DH system. And, as the volumes of waste 

are expected to increase in the years 

ahead, DH and electricity from incineration 

plants represent an increasing share 

of energy supplies. 

in a DH system where high levels of re are 

desired, geothermal energy can reduce 

dependency on biomass, but analyses 

show that within the existing frameworks 

and costs, geothermal energy remains 

a more expensive solution. geothermal 

energy could be an economically attractive 

long-term alternative to cHp based 

on biomass if biomass prices rise more 

than expected or if demand cannot be 

accommodated.

large solar heating systems and large 

heat pumps are more expensive solutions. 

However, these technologies may 

also become interesting in DH systems 

in the long run. the analyses indicate 

that integrating technologies into the DH 

system is far cheaper than establishing 

individual solutions. this for instance applies 

to large solar heating systems for 

DH, compared with small solar heating 

systems on individual buildings. 

in the long term, electric heat pumps 

could be a cost-effective re solution, 

as long as the electricity generation of 

northern europe has a high share of re 

– wind power in particular. 

Drastically reduced co2 emissions 

the project has studied the consequences 

of expanding the DH system to nearby 

areas supplied with individual natural gas 

heating. the results of the analyses reveal 

environmental and economic benefits 

would be achieved by expanding the supply 

to include large customers in areas with 

natural gas, as fuel savings far outweigh 

the costs of connecting new customers. 

The next steps 

now that Heat plan greater copenhagen 

is complete, a series of scenarios for the 

future DH system in the metropolitan 

region have been carefully prepared. the 

analysis is not a formal heating plan in the 

sense of the Danish heating supply legislation, 

but the project indicates a number 

of actions (recommendations) that can be 

taken in the future that will benefit the 

various actors on the energy scene.

DH companies, energy producers 

and municipalities. 

the DH companies ctr, copenhagen 

energy and VeKs will continue to work 

with energy producers to establish a 

way to use larger volumes of biomass for 

DH in greater copenhagen. this includes 

focus on transportation and storage of 

biomass. the companies will also investigate 

the specific scope for establishing 

a larger geothermal plant, and analyse 

bottlenecks in the DH system and how 

they can be reduced or removed altogether. 

Finally, the companies – together 

with local authorities - should focus on 

switching users from individual natural 

gas heating to DH and on heat savings at 

the end-users. the effort should focus on 

areas which will ensure a longterm, stable 

emissions of co2

drive to cost-effectively reduce heat 

consumption. Meanwhile the heat companies 

and energy producers must focus 

on developing new energy sources for DH 

production, including geothermal plants 

and solar heating, in order to reduce long 

term dependence on biomass. 

Parliament 

to realise the many promising opportunities 

for a sustainable conversion of the 

DH system, it is important that parliament 

is supportive through a consistent energy 

policy that enables long term investments 

in the DH system. this involves, for example, 

that the current tax policies that 

favours re must be at least maintained 

or even better: improved.

visit ChinA And mongoliA 

ulaanbaatar District Heating company turns 50 

ulaanbaatar District Heating company celebrated its 50th 

Anniversary in september 2009 and DBDH was invited to honor 

the achievements made by the district heating company over the 

past 50 years in the coldest capital in the world: ulaanbaatar. 

Mr. Hans Bjørn, chairman of DBDH and Mr. Jes B. christensen, 

Managing Director, were invited by Mr. Byamba-ochir, general 

Manager of ulaanbaatar District Heating company. it was a 

three day celebration epitomizing the best of Mongolia from its 

cultural heritage in singing, dancing and acrobatics to the unique 

and beautiful landscape. 

Besides DBDH also cowi, Kamstrup, ABB, Hydro-X and Danfoss 

were invited as suppliers to the constant improvement of the 

district heating network crucial to the survival of the inhabitants. 

with an average temperature of around minus 25 degrees 

celsius five months of the year and another two months with 

temperatures below zero on average the district heating system 

is pivotal. 

it became very clear during the visit that Danish district heating 

solutions have been essential for uB during the last ten years and 

with the opening of a brand new Booster pump station, supplied 

by ABB Denmark, during the visit, Danish solutions will also be 

the strategic choice securing comfortable, reliable and efficient 

district heating in the future. 

china District Heating Association and 

DBDH takes it up one notch 

the members of DBDH in particular ABB, ApV, Broen, Brunata, 

cowi, Danfoss, grundfos, Hydro-X, and Kamstrup have for more 

than ten years been exploring the opportunities for developing 

district heating in china. these 9 companies have for the past 

almost ten year’s jointly under the umbrella of DBDH china toured 

Zhongguó 4 times a year visiting numerous provinces organizing 


seminars, b2b meetings as well as visiting both combined heat 

and power plants and heating only plants. it is the long lasting 

friendship based on mutual respectful, understanding, and collaboration 

from exchanging ideas and solutions with the result of 

a more reliable and sustainable urban infrastructure with district 

heating as the backbone for both nations. 

in conjunction to visiting the neighbour to the north, DBDH 

chairman and Managing Director naturally visited Beijing, china. 

the purpose of the visit was for the chairman of DBDH Mr. Hans 

Bjørn to meet his counterpart Mr. liu Diansheng, chairman of 

china District Heating Association. 

the history of formal cooperation between DBDH and cDHA dates 

back to June 1994. over history the two associations have facili- 

tated many exchanges of visits and information sharing. District 

heating is both in china and Denmark highly viewed as a solution 

ensuring energy security and combating climate change. 

the main item on the Agenda for the meeting was chinese par- 

ticipation in the international District energy summit: “District 

energy - leading the way to copenhagen”, which took place on 3 

november 2009 in copenhagen (see pages 22-23). the District 

energy summit in november forwarded recommendations on how 

district energy enable cities to become sustainable by utilizing 

the flexibility and efficiency district energy provide jointly with 

combined heat and power systems. 

Mr. liu Diansheng joined the conference in november with col- 

leagues from the chinese district energy sector, hereunder with 

representatives from Beijing District Heating group, the single- 

largest district heating system in the world. 

other issues of cooperation looking ahead were also discussed and 

the two new chairmen quickly learned they have a long history of 

great friendship behind them in their relatively new positions.

hAmbuRg hAFEnCity: suPERlAtivE City dEvEloPmEnt 

By Mr. Michael schumburg, Danfoss gmbH, Hamburg 

the use of district heating is not widespread in germany. one 

exception, however, is Hamburg which has a vast district heating 

network supplying 19% of all households with district heating, 

compared to just 8-14% in other parts of the country. politicians 

in charge have declared that the district heating infrastructure 

will continue to be expanded; their goal is to connect 50,000 additional 

households to the district heating network by year 2020. 

with Hafencity, a whole new city quarter has been created in the 

heart of Hamburg. it is currently the largest inner-city development 

project in europe - 155 hectares of harbour area - and is 

setting new standards with its mix of apartments, offices, recreational 

facilities, retail trade and culture. this is also true for 

its energy supply; city planners aimed at the most sustainable and 

economically advantageous long-term solution, and the result is 

district heating supply for all buildings. 

in essence, the concept is based on the combination of the existing, 

well-proven Hamburg district heating system with decentralized, 

local heating distribution units. the fuel used is mainly coal, 

along with household and industrial waste, natural gas, and very 

small quantities of light fuel oil. to further reduce carbon dioxide 

emissions, the existing Hafencity heating plant is equipped with 

a steam turbine and a fuel cell as a pilot project. in addition, two 

new combined heat and power plants are planned. Buildings which 

are mainly for residential use will be equipped with solar energy 

panels for the central domestic hot water supply. 

local presence of Danfoss adds value to Hafencity 

building projects 

Application knowledge and a comprehensive range of products 

have made Danfoss systems and automatic controls a natural 

choice in several projects including both floor heating and radiator 

heating. project manager of the company reese Beratende 

ingenieure, Judith Huber-Jahn, says: “given a choice, i would certainly 

opt for Danfoss products. the quality of the equipment is 

outstanding, and the available service and support is also a big 

plus. For more complex installations, Danfoss specialists help 

us with questions regarding the construction and design. And if 

something does not go according to plan on a construction site, 

Danfoss employees are on hand to come and advise us on site.” 

HafenCity: The harbour of HafenCity – a mix of residential and commercial 

buildings right at the waterfront. 

conclusion 

the district heating supply in Hafencity is a cost-effective and 

sustainable solution. Hamburg’s prestigious project is a model 

for successful city development and not just for architectural 

reasons. the energy concept also sets standards. the Danfoss 

control equipment installed in a wide range of buildings for the 

distribution of district heating ensures that every single kilowatt 

of energy is used as efficiently as possible, to the benefit of house 

owners, tenants and the energy supplier. 

A modern district heating installation in 

HafenCity – optimized for energy savings. 

Hamburg – the district heating capital of Germany 

in 1893, the first district heating pipes were laid in Hamburg. 

today, the district heating network in the city has a total 

length of 740 km and supplies 410,000 dwellings – 19% of the 

total number of households. 

the rest of germany is also catching up on the idea of district 

heating, and in particular combined heat and power (cHp) has 

made its entry on the political scene. By 2020, the goal is to 

increase the share of electric power from cHp to 25% and 

the government will support cHp projects with € 750 million 

annually. experts predict that this will result in a 25% increase 

in the share of district heating supplied dwellings by 2030.

RoAd shows in RussiA by thE RussiAn-dAnish tEAm 2009 

2009 was exciting and busy for the russian-Danish team rooted in 

DBDH – when the team continued sector Visits in the Volga area. 

More than 1/3 of the DBDH members are actively doing business 

in russia, either they have build up own production, entered into 

joint ventures or are dealing through local distributors. these 

companies have joined forces anchored in DBDH, and back in 2007 

made the decision to arrange at least 2 big events yearly under 

the headline “Danish District Heating sector Visits”. 

together with locally represented Danish industries, we have 

built up a strong team, which have planned the strategy and 

the program. project manager svetlana chernova, royal Danish 

embassy in Moscow and commercial counselor Klaus sørensen, 

Danish consulate general in st. petersburg have also taken great 

part in this work. 

the Danish ambassador Mr. per carlsen, by the way speaking 

fluently russian, has supported our conferences and exhibitions 

in russia all the way and opened many a door for the russian- 

Danish team. in addition we have had the valuable support from 

the Danish energy Agency by senior policy Advisor Mr. Anders 

Hasselager who has opened the seminars “energy savings and 

energy efficiency” by giving an insight to the remarkable results 

in Denmark . we thank both Mr. carlsen and Mr. Hasselager for 

their sincere engagement in the work of our team. 

in 2008, the team went to perm, izhevsk, samara and saratov, and 

in 2009, we continued the road shows of the Volga region. 


spring: sector visits to nizhny novgorod and yaroslavl 

nizhny novgorod is the capital of the Volga district and apart from 

being the third largest city of russia, it is also one of the oldest, 

founded in 1221. yaroslavl city is part of the “golden ring” around 

Moscow and will celebrate its 1000 year jubilee in 2010. these two 

major historic cities were the goals of an April visit. 

the “russian-Danish conference on energy savings and energy 

efficiency” was opened at the president Hall of nizhny novgorod 

Fair under much attention from the district heating and industry 

sector, tV, and newspaper Medias. the conference was divided 

into two parts, a ”concept seminar” addressing the political 

level, and a ”technical seminar” aimed at design institutes and 

the technical level of the district heating sector focusing on the 

technique behind the results in Denmark. the conference also 

included round table meetings with the district heating sector in 

nizhny novgorod to discuss the topics the region is facing today 

and how we can cooperate on future projects. 

A 9-hour long train trip through the russian landscape brought 

the delegation to yaroslavl, ready for the second part of the 

Danish District Heating sector visits. As in nizhny novgorod, an 

important part of the conference in yaroslavl was the round table 

meetings. Many people within the district heating sector showed 

up to take part in the discussions of possible russian-Danish pilot 

projects. A representative from the Danish Ministry of climate 

and energy, Ms. oxana chueva, presented possibilities for financing 

large energy projects by Joint implementation. At present 

Denmark is involved in 6 projects of such kind in russia.

Deputy governor of yaroslavl, Mr. Andrey V. yapaneshnikov, at- 

tended the last part of the round table meetings, and confirmed 

the interest in entering into cooperation with the Danish side. 

“we lack the money to invest in energy saving projects, however 

if we do invest – then we will get money. so we need to start turning 

the view of presenting the problem” said mr. yapaneshnikov. 

First step will be the signing of the letter of intent, followed by 

the establishment of a working group with suppliers, designers, 

and consultants. 

Autumn: In november the DBDH team went to orenburg & 

chelyabinsk connected with a full one-day stop-over in Moscow 

to meet Jsc “e4 group”. e4 group comprises the leading russian 

engineering and other industry-related companies. general 

Director of “e4 group” Danil nikitin said in his opening remarks “i 

am confident that partnership with Danish companies will contribute 

to the successful implementation of large-scale state 

energy saving programs. the Kingdom of Denmark is absolutely 

correctly called the Kingdom of energy efficiency”. All present 

Danish companies made a comprehensive presentation of their 

company and their technologies including a fruitful Q & A session 

after each presentation. 

From Moscow the delegation continued to orenburg for a two- 

day program including conference and round table meetings . 

More than 150 guests participated in the event, among them 

the governor of orenburg region, Mr. sumin, who opened the 

conference and mentioned that Denmark is one of the countries 

to which orenburg region look for inspiration when implementing 

new energy efficient solutions. other participants were representatives 

from government and Municipal level, district heating 

companies and enterprises in the dh sector. During round table 

meetings, topics of interest were energy planning and the Danish 

model of cooperative ownership. 

From orenburg the delegation continued to chelyabinsk, some 

700 km northeast through the ural Mountains. the visit coincided 

with the annual speech of president Medvedev in which he had 

called for a more efficient use of energy resources, as well as 

the development of alternative energies. chelyabinsk region has 

adopted several programs on energy efficiency in the region in 

which also Danish companies have been part. Metering systems 

and exchanging of the pipe systems are important priorities. 

russian edition of Hot/cool was also published in 2009. the 

magazine is sent free of charge to all our contacts in russian 

speaking countries and is being distributed during road shows 

and visits in this part of the world. Furthermore delegations visiting 

Denmark has enjoyed reading it too. Foreword is by russian 

Ambassador t.o. ramishvili, who mentions the huge potential of 

russia for energy savings – 40-50% of the current consumption. 

this calls for continued cooperation between russian and 

Danish businesses in the energy sector. other articles of the 

magazine present case stories and state-of-the art solutions 

and technologies. guest-editor-of-chief of the magazine was 

energy planner Mr. Anders Dyrelund, rambøll. 

A busy year, many new business relations, and indeed many superior 

impressions. we look very much forward to continuously doing 

road shows in this part of the world. in the coming year we will 

go even more to the east, more precisely to Krasnoyarsk, irkutsk, 

novosibirsk and omsk.

PARAdigm shiFt FoR dbdh AFtER 30 yEARs 

oF unChAngEd ConCEPt – dbdh is nEw mEmbER oF 

thE ConFEdERAtion oF dAnish industRy (di) 

1 october 2009, in the beautiful surroundings of Hvedholm castle 

in Faaborg, DBDH’s 40 members voted for admission to the 

confederation of Danish industry (Di). the rules and the changed 

market conditions for propagation of the Danish district heating 

and cooling solutions require focused policy work and a larger 

systematic agenda setting in europe. 

since 2008, DBDH’s Board of Directors has intensively been work- 

ing on the right structure of the organisation to accommodate 

the constant development around DBDH and demands within. At 

the members’ meeting 1 october, members were faced with the 

choice between an unchanged DBDH or becoming part of the Di 

family. the cardinal point was how the industry best allocated its 

resources to meet future demand while creating highest possible 

value for all individually and jointly. Joining the best from 

both organisations would elevate the industry’s empowerment 

to achieve the goal of greater acknowledgement be recognising 

the opportunities this industry offers to society. 

the cooperation between the Board of Directors and the Di 

agreed on the following vision and mission in order to fulfil the 

common ambitions: 

Vision: District energy shall be recognised as a system integrator 

for all available energy resources in a community thereby 

ensuring optimal (a) use of energy, (b) energy efficiency and, (c) 

climate improvements. 

Mission: to contribute to a reduction of global co2 emissions 

by focusing on energy efficiency and exploitation of the 

society’s exhausted energy from production of power, industrial 

processes and waste incineration, as well as use of renewable 

energy sources. 


A strong majority decided that from 1 January 2010 DBDH is a 

member of Di. it was agreed that the synergies that will arise in 

a close cooperation between the Di’s political skills and DBDH’s 

market approach, and years of industry knowledge, will both 

prepare and strengthen the organization to embrace future challenges. 

DBDH will, under the umbrella of Di, be better prepared to 

connect to the political challenges and the market opportunities, 

so Danish energy, in the future, will be associated with a greener 

and a more sustainable system. 

DBDH and DI 

DBDH will continue to have its own board of directors, 

regulations and secretariat. 

the first joint mission is the continuation of work in relation 

to the european parliament and council Directive 2009/28/ 

eF from 23 April 2009, and the eu commission Decision of 

30 June 2009, which states that the Member states by 30 

June 2010 must submit a national action plan for the national 

renewable energy policy and the set up targets. 

A stronger DBDH under the umbrella of the Di, where the 

interaction between policy and export reaches new dimensions 

will play a pivotal role for the possibilities of Danish 

district heating and cooling solutions internationally.

DBDH visits chicago with HRH crown Prince Frederik 

in marts 2009, DBDH and Danfoss joined a specially invited visit to 

chicago with their royal Highnesses crown prince Frederik and 

crown princess Mary of Denmark addressing climate change with 

urban sustainability solutions. 

HrH crown prince Frederik of Denmark, Mayor of chicago richard 

M. Daley, and the Ambassador of Denmark to the united states 

Friis Arne petersen opened the exclusive session with visionary and 

inspiring speeches. Following the commendable opening addresses 

the panelist’s from public, private, non-governmental organization 

(DBDH) and financial leaders from both us and Denmark exchanged 

ideas and experiences on how to both smartly and efficiently tackle 

the growing challenge of global warming. 

HrH crown prince Frederik both emphasized the fact “that global 

warming is happening, and that we, as humans, are contributing to 

it”, and asked the unequivocally and pivotal climate question “how 

do we promote growth and economic development while preserving 

a sustainable environment?”. 

HrH crown prince Frederik comforted the crowd with a case from 

real life. “My country, Denmark, has demonstrated that it is possible 

to combine economic growth and job creation with climate friendly 

policies. For several decades our carbon foot print in energy has 

been shrinking, while our economy has been growing. Many of the 

businesses participating in this conference today are proof that 

green energy can create new market opportunities.” 

Mr. lars Dyrhagen, Vice president public Affairs for Danfoss group, 

spoke and participated with insights to energy efficiency solutions 

for heating and cooling. 

Mr. Jes B. christensen, ceo for DBDH, touched on the topic of 

challenges to integrate urban infrastructure. His final remarks 

rejected the allegation that co2 taxes and collective system 

solutions like district energy hurts businesses and happiness 

of people. “the economist labeled in 2008 Denmark number one 

country in the world to do business and establish business. the 

university of Michigan ranked in July 2008 that Denmark was the 

happiest nation as well.” 

Mayor Daley pointed out that the city of chicago and Denmark has 

the same prudent approach to combat climate change. 


the day was encouraging and district heating and cooling solutions 

were high on the agenda. 

DBDH celebrates IDeA centennial show in washington, Dc 

Danish Board of District Heating and 8 suppliers of district energy 

solutions (rambøll, Dall energy, Danfoss, logstor, grundfos, cowi, 

7t, and Kamstrup) joined the iDeA centennial conference and 

exhibition in washington, Dc. under the united headline “guide to 

District energy – community Development” the companies each 

gave a presentation on their part in the system integrating solution 

to connect the opportunities for communities to utilize the 

existing and available low-grade energy resources. why waste 

heat? 

the advantages offered by hot water based district energy such 

as decreased heat losses, lower maintenance costs, lower water 

treatment costs, increased energy efficiency, supply security and 

no risk of explosions etc. were pointed out at the iDeA centennial 

exhibition and conference by the Danish participants. 

the iDeA centennial celebration was attended by more than 700 

people from 15 countries, and of course DBDH was there as well 

celebrating a valuable partner. 

IDeA visits Denmark twice in 2009 

As co-organizers of the 1st global District energy climate 

conference on 3 november 2009 in copenhagen, the chairman 

and iDeA president visited Denmark. During their visit they also 

had the opportunity to join the guided district energy tour around 

copenhagen in cooperation with energy tours and rambøll. 

Mr. rob thornton, iDeA president, came back for the un climate 

conference (cop15) in copenhagen and Bright green exhibition 

and conference at Forum. in this regard the us Ambassador to 

Denmark laurie s. Fulton supported the bilateral exchange of business 

opportunities with energy technology and smart solutions by 

hosting a dinner reception at the Ambassador’s residence. 

the cooperation between usA and Denmark on district energy 

solutions will continue and the us climate stimulus package 

negotiations scheduled for spring 2010, only emphasizes the 

increased opportunities for the development of district heating 

and cooling in usA, already the second largest importer of Danish 

energy technology.

ConFEREnCE: 

thE RolE oF distRiCt hEAting in FutuRE ClimAtE PoliCy 

By Ms. eva rasmussen, Managing Director, FiF Marketing 

the Danish district heating sector was invited by DBDH and FiF 

Marketing to a conference held at Denmark’s parliamentary 

building, christiansborg, in copenhagen on 2 April 2009. over 150 

people in the sector attended the meeting. 

The Danish model 

the first minister to open the event was the former Minister for 

climate and energy, connie Hedegaard, today eu’s first climate 

Action commissioner. she praised district heating as the most 

energy-efficient type of heat supply. “Denmark’s district heating 

model is a crucial prerequisite for the satisfying results we have 

achieved in terms of energy,” she stated, and backed up her statement 

with the following statistics: “the percentage of district 

heating coming from cHp in Denmark has grown from 40% to 

double in just 20 years, and, in the same period, the percentage 

of district heating generated from renewable energy sources has 

grown from just below 10% to around 50%. if district heating was 

not part of Denmark’s energy system, our country’s carbon emissions 

would consequently be 8 to 11 million tonnes higher.” 

Heating Plan Denmark 

the next speaker, professor Henrik lund, Aalborg university, 

used the report Heating plan Denmark to document how the 

goal of having a carbon-neutral heating sector by 2030 can be 

achieved. it will require political support and action which includes: 

enlargement of the heating market share from the current level 

of 46% to somewhere between 53 and 70%, more efficiency in 

the production, more renewables in the energy mix and greater 

utilisation of waste incineration. Furthermore, consumers must 

save an additional 25% on their heating use, partly by improving 

their cooling method, he concluded. 

The climate governs energy-sector taxation 

Kristian Jensen, the Danish Minister for taxation, spoke about 

how to design a well-functioning tax system in the energy sector. 

“when designing taxes and charges for the energy sector, 

we work with many factors simultaneously. our goal is to lower 

our carbon emissions, to enlarge the share of renewables and to 

reduce our use of energy. climate-related considerations govern 

how the system is put together, and this is where we use taxes, 

because they work,” Kristian Jensen concluded. 

District cooling is an energy saver 

lars therkildsen, Managing Director of copenhagen energy, 

highlighted the potential of district cooling. the first large-scale 

district cooling project is currently being constructed at Kongens 


nytorv square in copenhagen, but the potential for district cooling 

is enormous, and there are currently ten projects being planned 

throughout europe with Danish involvement. “compared to ordinary 

private cooling systems, preliminary calculations show that 

collective cooling systems provide 80% more electricity savings 

and reduce carbon emissions by 70%”, he concluded. 

More interaction and more research 

Jørgen g. Jørgensen, Director of the Danish District Heating 

Association, explained that district heating is under an obligation 

to make an active effort to ensure Denmark can meet the 

carbon targets it has set. “we have a good heating system, but 

to be the future’s leading technology, we need more energybased 

research”, he concluded. Jens stenbæk, chairman of the 

Association of local Authorities, confirmed the expediency of 

enhancing the interaction among municipalities, local energy 

companies and nation-wide efforts in the field of energy. “Many 

small projects are carried out in the municipalities without taking 

a holistic view of heating and energy planning and that is not 

always energy-wise”, he claimed. 

emergence of district heating 

Mogens olsen, science officer at the British embassy, described 

how district heating is emerging in the uK. Both southampton 

and sheffield are e.g. supplied with heat from a central district 

heating plant. But still only 1% of the heating requirement is met 

by district heating and 77% of all houses in the uK are heated 

by gas. the uK’s goal is to reduce its carbon emissions by 60% 

by 2050. 

Jes christensen, Director of DBDH, completed the day by present- 

ing hard facts about district heating and the increasing growth, 

exports figures and the increasing number of employees in the 

Danish DH sector.

how EFFiCiEnt CAn it bE? 

By sales Director, Mr. Bent Have Johnsen, Aalborg engineering A/s 

During decades the Danish industry of energy producing equipment 

has been pushed for achieving higher and higher goals. the 

pressure has come from the shifting governments in order to 

release Denmark from import of energy to being independent. 

the results have been shown in many ways. these years the most 

visible effect has been the renewable energy market. there are 

however other technologies which has proven its co2 and emis- 

sion reducing capabilities previously. 

in 2003, Aalborg engineering was awarded the heat recovery boiler 

for the new block 8 on H.c. oerstedsvaerket in copenhagen. the 

plant would be a part of a master plan for the complete district 

heating system of the capital. Basis for the plant was a gas turbine 

(today known as a siemens sgt 600) which was moved from 

naestved to the site in copenhagen. 

in order to meet the required capacity the gas turbine had to 

be equipped with a heat recovery boiler with the possibility of 

increasing the production considerably. During the project study 

Aalborg engineering worked closely with the plant owner to make 

the best technical and feasible solution. the result was a heat 

recovery boiler with a high degree of supplementary firing using 

natural gas. 

in this solution we made it possible to increase the basic gas 

turbine load with additional app. 60 Mwt. the parameters were 

defined as low pressure steam for the copenhagen district 

heating system as well as district heating water. the plant was 

defined to have approx 500 annual operating hours. not much 

compared to the work carried out and investment made. But 

still the installed capacity had to cover for the expected ambi- 

ent conditions of the city and to make sure there were sufficient 

heat for the consumers. 

the plant was installed in an old power plant building. this fact 

required extraordinary efforts to avoid making any changes to the 

old building which was considered worth preserving. the installation 

was made through the basement and access ports just 

below roof level. the plan succeeded and today a modern efficient 

plant is producing heat for the city of copenhagen. 

speaking about efficiency there are some quite interesting operational 

features the heat recovery boiler is build for. As mentioned 

it was expected to use the installation for approx 500 hours per 

year. today, after five years of service the plant has become base 

load. that means the plant is scheduled to operate all the time. 

Due to the combination of producing power and heat this is the 

most feasible installation of the system. the heat recovery boiler 

has an efficiency as high as 98 % when the plant is on full gas 

turbine and supplementary firing mode. 

indeed an achievement which is difficult to speak against even in 

a time where fossil fuels in general are considered problematic. 

let this be a good example of the climate friendly and prudent 

fossil usage.

distRiCt hEAting 

ClimAtE summit 

in november 2009, the first 

District energy climate Award 

took place in copenhagen, and about 200 

people from more than 40 countries participated. the 

event was an occasion to award outstanding innovative projects 

and to highlight district energy systems that were making a difference. 

27 cities/systems from all over the world were showing 

their interest by sending applications. these applications can be 

downloaded at www.copenhagenenergysummit.org. 

Two main activities were at the agenda for the event: 

1) election of the winners of the first District energy climate 

Award 

2) to hand over a set of recommendations to call upon all parties 

involved in the negotiations of the new climate deal at the 

cop15 in December in copenhagen. the recommendations were 

made to guide the decision-makers who were gathered at the 

cop15 in their search for pragmatic and easy-to-implement 

solutions that combine economic and ecological benefits 

The award was serving to: 

• provide a platform for sharing ideas and efforts that have 

made systems successful 

• identify and recognize systems that illustrate the overall 

importance of district energy in providing sustainable energy 

solutions 

• provide a global benchmark for environmental excellence 

the panel of judges, which the ieA chaired, selected 6 winners of 

the 27 applications from 11 countries. the 27 applications represented 

very large metropolitan areas as well as communities, cities, 

towns but also a university campus and an industrial park. 

the following text describes shortly the background of the 6 

winners of the climate Award: 


university of Texas at Austin, united states 

the ut Austin is a large university campus serving 70,000 students. 

200 campus buildings are connected by a district energy system 

with several high-efficiency features, including cogeneration. As 

a result of the system, the campus’ co2 emissions have remained 

flat in spite of increasing campus energy demands. 

Borås, sweden 

55% of Boras’ 64,000 residents rely on the town’s innovative 

district heating system, which receives its energy from a cogeneration 

plant using a mixture of biomass, waste and landfill gas. 

Borås use biodegradable household waste in production of biogas 

for bus transport and the production of fertilizer. 

copenhagen, Denmark 

the district energy system in copenhagen covers 98 % of the 

city’s heat demand. the system is part of a wide-ranging network 

covering the city centre and 15 suburban districts. the system 

is pioneering the large-scale use of renewable resources via the 

integration of cogeneration, biomass and solar energy. 

Dunkerque, France 

this district heating system recycles surplus energy from France’s 

largest steel mill. the city has added three cogeneration units 

and a second surplus heat capture unit at the steel plant and 

increased the share of recovered energy in the network to 90%, 

significantly lowering overall co2 emissions. 

Jiamusi, china 

this pioneering system includes a vision for growth to 2020, when 

the network will supply 14.5 million m2 of area, representing 75% of 

the city’s current heating surface. the current plant has already 

reduced co2 emissions significantly through the replacement of 

over 60 coal-fired boilers.

Krakow, Poland 

social and economic transformation has strongly influenced local 

heat distributors so that the heat market has grown in size 

and competitiveness. Krakow’s system demonstrates a modern, 

efficient system that is providing energy and economic savings 

while reducing greenhouse gas emissions, e.g. through the closure 

of 392 coal-fired boiler units over the period 1990-2008. 

the presentations of the winners can be downloaded at www. 

dbdh.dk 

At the end of the presentation richard Jones (ieA Deputy 

executive Director) said: these communities are showing the 

world the path forward on climate change: low-carbon, energy 

efficient district energy systems are win/win/win solutions for 

the environment, energy security and local economic growth. we 

hope that other cities will look to these models as examples.” 

The recommendations 

the second and very important activity at the event was 

the outline of the set of recommendations that were 

made to call upon all parties involved in the negotiations 

of the recently ended cop15. the aim was to involve all 

the parties at the cop15 negotiations and to make aware 

of a technology that is proven and reliable, convenient 

to use, and highly cost-effective in combating climate 

change. 

the set of recommendations were happily accepted by 

the cop 15 Hostess Minister Ms. connie Hedegaard (now 

the first eu commissioner for climate) and in a letter 

of thanks to the organizers of the summit (received 9 

november), she wrote: 

(...)the conference was indeed a very timely initiative 

and a positive contribution to the international negotiations 

prior to the 15th conference of the parties 

(…). emphasising the importance of cities, district 

energy and cogeneration in regard to global climate 

issues will hopefully bring us one step further on the 

way to copenhagen. 

Danish experience shows that district heating and cogeneration 

are significant elements in the fight against climate change and 

the development of more sustainable cities. i am pleased to learn 

from the conference that cities and urban communities from all 

over the world are actively involved in mitigating climate change 

and that a number of cities have been granted the first global 

District energy climate Award for their municipal efforts. 

the summit itself did provide an opportunity to demonstrate the 

principles and benefits of district energy and it brought together 

government representatives, policy leaders and environmentalists. 

At the summit people like Doug parr of greenpeace uK, seiichi 

Kondo (the Japanese Ambassador of Denmark), and the former 

swedish environment Minister lena sommestad participated as 

well. it was an opportunity to experience first-hand how district 

energy can deliver higher efficiency, greater fuel flexibility and 

more sustainability.

REliAblE uPgRAdE to gREEn EnERgy 

By Mr. Jesper g. Jensen, Jgkomm, for Bwsc 

it is not a bad smell...it is renewable energy, with environmental 

and financial potential for the community. we have to change the 

way we perceive organic waste products. they represent a vast 

and valuable energy resource right in front of us. lemvig Biogas 

has, with assistance from Bwsc, realized the potential. 

Biogas has the potential of replacing up to 25% of Denmark’s 

consumption of natural gas to replace the Danish natural gas 

resources starting to decline from 2015. 

in 2009, the Danish government launched an ambitious plan to 

promote ‘green growth’. A significant element in the plan is to 

utilize half of the country’s livestock waste into energy by 2020. 

ten years prior to this deadline, we are utilizing approximately 7%. 

so it will take a substantial effort to reach the target. 

the most obvious means is to build 40-50 new, large scale biogas 

plants. leading experts are, however, not convinced that this is 

feasible within the time frame. Another means is to expand the 

treatment capacity on existing plants. 

“no matter which means we choose, the potential is there,” says 

ceo sigurd Ø. Andersen from Denmark’s leading energy plant developer, 

contractor and supplier, Burmeister & wain scandinavian 

contractor A/s (Bwsc). “But we must change the way we perceive 

biomass. we tend to see the source as waste only. But in reality, 

these surplus bi-products are valuable energy and fertilizer resources 

which we have in abundance right in front of us.” 

in an environmental context, the potential has even more important 

significance, because we have to dispose of the ‘waste 

resources’ anyway – with minimal environmental impact. then 

why not benefit by its energy potential? And that is exactly what 

they have done in lemvig in west Jutland. Here, an existing biogas 

plant has recently been expanded to take in even more biomass, 

thereby increasing biogas production and expanding lemvig 

Biogas’ commercial potential. 

lemvig Biogas is one of the largest plant of its kind in Denmark, 

and it doubled its fermentation volume in 2008 to almost 15,000 

m3 coupled with an upgrade all performed by Bwsc. 

the expansion and upgrade have provided lemvig Biogas with a 

potential to expand their business beyond the present customer, 

lemvig District Heat and power. now other district heat and 

power plants in the vicinity can have the benefit of the biogas to 

replace a part of their current fossil energy source. 


Develop for the future 

Back in 1992, Bwsc built the original lemvig Biogas plant and 

was also selected to expand and upgrade the plant in 2008. the 

purpose was to increase the gas output from the biomass and 

to develop the plant for the future. 

the fermentation tank capacity had to be substantially increased 

to ensure both sufficient and efficient digestion of the biomass 

supply from livestock waste combined with other industrial material 

such as fish waste, slaughterhouse waste, bacteriologic 

contaminated foods etc. 

the new tank was serial-connected to the existing tanks to 

improve digestion even further together with an upgrade of the 

pasteurization at the plant. And the original gas treatment system 

was upgraded to be able to handle the increased production. 

Reliable long-term solutions 

A local study in lemvig showed that the community could increase 

their financial benefit through a more efficient utilization of the 

biogas plant, so the decision to expand the plant was evident. 

And the decision to contract Bwsc to perform the expansion 

was not hard to make either. 

Bwsc has built some of the most efficient and longest serving 

biogas plants in Denmark and that is no coincidence. 

“we strive to use our vast knowledge and experience in the turnkey 

field to design plants specifically to the customer’s needs,” explains 

sigurd Ø. Andersen. “we use solid and well-proven concepts and 

equipment with high reliability and predictability of the biogas 

plant, which together with the management of the organic waste 

resources at the plant provide a solid basis for the financial performance 

of the plant for the customers.” 

But sigurd Ø. Andersen is also aware that Bwsc’s biogas enthu- 

siastic customers cannot realise the 2020 targets by themselves. 

“Biogas is a sound and sensible energy alternative which represents 

double sustainability – both environmentally and financially 

– for a society very much in need of such solutions. therefore, we 

can only hope that the good intentions behind the ‘green growth’ 

plan will be followed through with the sufficient framework conditions 

to ensure that the target is reached,” he concludes.

go to youtube, search district heating, and the next thing you 

know you are part of the Midsummer eve celebrations on a 

warm summer night in Denmark. with the amazing bonfire along 

the beautiful coastline, the scene is set for telling the story of 

district heating in Denmark. 

well, actually, you can also find a copy of the DVD inserted in this 

Annual report! 

in cooperation with FiF Marketing, DBDH has published the film on 

district heating and cHp in Denmark. the title of the film is ”Just 

imagine” and we are rightfully proud of the result. see it and judge 

for yourself! Many did already during cop15 when the film was 

shown on wide screen at the town Hall square in copenhagen. 

with over 60% of Danish buildings receiving heating and hot 

water via district heating (80% of which comes from surplus 

energy sources), Denmark is the world leader in District Heating 

and cooling technology. District heating has played a vital role in 

reducing Danish energy consumption, to the extent that Denmark 

has been self-sufficient energy-wise since 1997. with district 

heating and cooling technology Denmark has reduced co2 emissions 

per sq. metre, the share of fossil fuel consumption 

per sq. metre, and the total energy consumption 

per sq. metre for space and water heating. 

in terms of combating climate change 

and reducing co2 emissions, no other 

technology offers industrial nations 

the potential of meeting the requirements 

of energy saving and 

emissions reduction, without affecting 

the standard of living and 

productivity of the nation.

imPRovEd sECuRity with AutomAtiC lEAk suRvEillAnCE 

By web editor, Mr. gert skriver, Kamstrup A/s 

At the cHp Feldborg-Haderup in central Jutland, the operating 

Manager svend Jensen is pleased with the strong position of his 

utility and its services in the mind of the heat customers. the 

utility is not only supplying the 500 residences with heat, but is 

in addition offering leak surveillance. 

recently one family’s house in the village Feldborg was saved from 

destruction because of the leak surveillance. 

some three years ago the utility invested in new heat meters and 

a radio mesh network for automatic meter reading for the sake 

of getting monthly readings of the consumption. 

But the automatic reading has provided extra opportunities for 

information gathering, and especially the leak surveillance has 

proven to be a manifest service that strengthens the role of the 

utility in local society. 

in 2009, a customer experienced a genuine bursting of the heating 

installation. one late evening svend Jensen called the residents to 

inform them that they had a problem. shortly after, he appeared 

at the residence and opened up into the basement from where 

steaming hot water was pouring out. Quickly the supply was cut 

off, and the day after the plumber exchanged the corroded pipes. 

A disaster had been averted. 

the reason for the operator’s quick arrival at the residence – even 

before the residents themselves found out there was something 

wrong – lies in the automatic meter readout and in his own sense 

of responsibility. 

the meters are linked together in a radio network. each meter 

contains a radio module transmitting consumption data to a 

centrally placed concentrator. From the concentrator the data 

are being transmitted via the gsM net to the server located at 

Kamstrup. 

Kamstrup runs a permanent operation surveillance which for 

svend Jensen is ideal as he is the sole member of staff at the 

utility: “i have nothing to do with the actual operation of the 

radio network. i just receive the information. Kamstrup notifies 

me if a module needs to be exchanged somewhere or mounted 

an extra antenna.” 

Among the collected data figures the actual as well as the accumulated 

consumption can be accessed directly by the operating 

manager from a computer at the utility. 

the principle of the leak surveillance is that the meters register 

the actual flow by comparing forward flow with return flow. A 

normal flow amounts to 50-70 litres/hour. if the flow exceeds 300 

litres/hour the system will automatically generate a leak alarm. 

the first person to receive the leak alarm via sMs is the operat- 

ing manager who can then pay a visit to the installation. the sMs 

contains the address. in the recent case the actual flow showed 

no less than 1,200 litres/hour. But a quick response ensured a shut 

down of the water supply after just 20 minutes from the time of 

the alarm. svend Jensen received the alarm at 9.45 p.m. which is 

actually a good deal past normal working hours. But as he points 

out: “it is important to respond with equal urgency every time; 

even in the middle of the night or on sundays. But it feels good 

to be able to offer that kind of service too. it gives the utility a 

stronger position in the community.” 

in this way svend Jensen has detected three serious leakages in 

the past two years. small leakages used not to be detected at 

all, but the system is so sensitive that they are being picked up 

too. in that case the operating manager receives the alarm by 

e-mail. He can then contact the customer by phone and inform 

them of the problem. 

often the alarm is caused by plumbing work where the heating 

system is being emptied. in one case a plumber had disconnected 

the meter from the return flow pipe which resulted in about 50 

leak alarms within two hours. “But i would rather turn out once 

too many times, than once too few,” says svend Jensen.

cHP share of thermal power and heat production 

for district heating 

By generating electricity and district heating together, it is possible 

to exploit the large amounts of heat generated by thermal 

electricity production. 

in 2008, 55.4% of thermal electricity production (i.e. the total production, 

excluding wind energy and hydropower) was generated in 

combination with heat, as opposed to 51.7% the previous year. this 

increase is in particular due to less exports of electricity in 2007, 

which led to a fall in electricity production at separate electricitygenerating 

plants. in 1990, the share was 36.8%, while the figure 

was 17.6% in 1980. 

in 2008, 79.7% of district heating was produced together with 

electricity. the corresponding figures in 1990 and 1980 were 58.8% 

and 39.1%, respectively.

Heating installations in homes 

the significant changes in the composition of energy consumption 

by energy type reflect changes in the composition of heating installations 

in homes over time. until the mid-1980s, oil-fired boilers 

clearly dominated the market, after which district heating became 

the most common source of heat. in the late 1980s and during the 

1990s, the number of district heating installations and natural gas 

boilers continued to increase at the cost of oil-fired boilers. 

As at 1 January 2009, the total of 2.7 mill. heating installations could 

be analysed as follows: District heating installations 61.1%, oil-fired 

boilers 14.5%, natural gas boilers 15.0% and other installations, 

including firewood boilers and electricity, 9.3%.

energy consumption for space heating in homes 

energy consumption for space heating fell from 178.4 pJ in 1980 to 

164.4 pJ in 2008, corresponding to a fall of 8.5%. the fall occurred 

even though the heated area increased by 31.4% in the same period. 

the fall in energy consumption took place from 1980 to 1990. After 

an increasing trend in recent years, consumption for space heating 

fell again by 1.2% from 2007 to 2008. 

in the period 1980 to 2008 energy consumption for heating per m2 

fell by 30.4%. this is due to improved insulation in older homes, and 

replacement of old oil-fired boilers with more efficient natural gas 

boilers and district heating installations. in addition, according to the 

building regulations, new homes must have lower energy consumption 

per m2 than existing homes. since 1990 energy consumption 

for heating per m2 has fallen by 10.8%.

composition of fuels in district heating production 

there was a significant change in the fuel used in the production of 

district heating in the period 1980 to 2008. in 2008 the distribution 

was: 46.2% renewable energy etc. (of which nonrenewable waste 

8.9%, biomass 35.4% and other renewables 2.1%), natural gas 27.8%, 

coal 22.0% and oil 3.8%. 

consumption of natural gas and renewable energy etc. has increased 

year by year. in 1990, the share of natural gas and renewable energy 

etc. was 17.4% and 31.6%, respectively (including biomass 24.9%). 

the percentage of oil fell sharply from 1980 to 1990, and has subsequently 

remained more or less constant. consumption of coal 

decreased significantly from 1990 to 2008. in 1990, this constituted 

44.2% of the total consumption of fuel for district heating.
