Large emission sources such as power plants, industrial plants and refineries
are included as large point sources in the Danish emission database. Each
point source may consist of more than one part, e.g. a power plant with several
units. By registering the plants as point sources in the database, it is possible
to use plant-specific emission factors.
In the inventory for the year 2010, 77 stationary combustion plants are specified
as large point sources. These point sources include:
• Power plants and decentralised CHP plants.
• Waste incineration plants.
• Large industrial combustion plants.
• Petroleum refining plants.
The criteria for selection of point sources consist of the following:
• All centralized power plants, including smaller units.
• All units with a capacity of above 25 MWe.
• All district heating plants with an installed effect of 50 MWth or above
and significant fuel consumption.
• All waste incineration plants obliged to report environmental data annually
according to Danish law (DEPA 2010).
• Industrial plants,
• with an installed effect of 50 MWth or above and significant fuel consumption.
• with a significant process related emission.
The fuel consumption of stationary combustion plants registered as large
point sources in the 2010 inventory was 325 PJ. This corresponds to 59 % of
the overall fuel consumption for stationary combustion.
A list of the large point sources for 2010 and the fuel consumption rates is
provided in Annex 2A-6. The number of large point sources registered in the
databases increased from 1990 to 2010.
The emissions from a point source are based either on plant specific emission
data or, if plant specific data are not available, on fuel consumption data
and the general Danish emission factors. Annex 2A-6 shows which of the
emission data for large point sources are plant-specific and the corresponding
share of the emission from stationary combustion.
SO2 and NOx emissions from large point sources are often plant-specific
based on emission measurements. Emissions of CO, NMVOC, PM, heavy
metals and dioxin are also plant-specific for some plants. Plant-specific
emission data are obtained from:
• Annual environmental reports / environmental reporting available on
the Danish EPA home page 3 (PRTR data)
• Annual plant-specific reporting of SO2 and NOx from power plants
>25MWe prepared for the Danish Energy Agency (DEA) and Energinet.dk
• Emission data reported by DONG Energy and Vattenfall, the two major
electricity suppliers
