very small shares. However, the amounts of waste for incineration now exceed
the capacity of the two existing plants in the area (one is beyond the project
area in the town of Skagen; the other is shown to the right), and it is planned to
build a new waste incineration plant. Consequently, the Energy Town project
includes a new waste incineration CHP plant with an expected net electricity
efficiency of 23% and a heat efficiency of 64%, and with an incineration
capacity of 185 GWh/year, equal to the available amount of local resources.

Expansion of District Heating Grid
The project also includes an expansion of the existing district heating grid,
whereby 70% of the heat demand in the presently individually heated houses
and industry is replaced by district heating. The demand covered by district
heating will thus expand from the present 190 GWh to a total of 236 GWh.
The rest of the industry (process heating) will be supplied from biomass
boilers, and the remaining individually heated houses will convert to a mixture
of solar thermal and electric heat pumps.
