The district heating in the large system (central Frederikshavn) is produced
on combined heat and power (CHP) plants, partly based on waste incineration
and partly including peak load boilers fueled by natural gas.
District heating in the small system (the northern suburb Strandby) is
produced on a small CHP plant fueled by natural gas, shown in the photograph
to the right.

The individual supply is based on oil- and gas-fired burners and a small
amount of wood.
Fig. 7.1 shows that a large share of the power demand in Frederikshavn is
already met by local wind power and CHP production. In addition to the
electricity production of the three mentioned CHP plants, 10.6 MW of near-
shore wind power placed at the Frederikshavn harbor (see photograph)
covers some of the demand. The rest is imported from the national grid. Here,
the latter is assumed to be produced on a coal-fired power station with an
efficiency of 40%, equal to the average of Danish condensing-mode power
plants.
