ANNUAL REPORT 2011 - DONG Energy

DONG Energy contributes to green growth
by establishing offshore wind farms
While the rising generation of electricity from wind benefits
customers in the form of greener electricity, DONG
Energy also contributes to value creation and economic
growth in the local areas in which the Group operates. In
connection with the construction and operation of the
Group’s new offshore wind farm at Anholt in Denmark, it
is expected that 8,000 jobs will be created in each of the
two years in which the farm is being constructed.
impact on customer consumption
On the consumption side, efforts are being made to make
consumer demand for energy more flexible so that consumption
more closely matches the periods in which high
levels of wind energy are being generated. Electric cars are a
good example of how flexibility can be incorporated in electricity
consumption. An electric car needs to be charged with
electricity to run. However, the charging does not need to
take place at the time at which the plug is inserted in the
socket. Customer needs will typically dictate that charging
takes place during the evening and the night, so that the
car is ready for use the following morning. With intelligent
“The Anholt project shows that the Danish suppliers in
the industry can hold their own internationally. All the
work was put out to tender on equal EU conditions, but
Danish-based companies won two thirds of the orders,”

systems in the grid and at the customer’s home, it is possible
to ensure that charging takes place at a time at which
there is surplus electricity generation from wind turbines but
consumption is low.
In 2011, DONG Energy began a trial of intelligent, flexible
electricity consumption in 155 private households. The
households were supplied with a ‘smart’ unit that reacts to
a price signal and starts or stops heat pumps, charging of
electric cars or other units with high electricity consumption.
The aim of the trial is to study the customers’ ability
and desire to interact with their electricity supplier to
achieve flexible electricity consumption.
