Question

How is district heat produced in Finland currently and in the future? More specifically:

How much district heat is produced in combined heat and power (CHP) plants versus plants which only produce heat?
What is the capacity range of district heat production plants?
What fuels are used in district heat production?

Statistics Finland^[1]:

Plant type:	Combined heat and power		Separate heat production
	GWh	Share	GWh	Share
Oil	291	1 %	2339	24 %
Coal	7422	25 %	675	7 %
Natural gas	9080	31 %	2789	29 %
Other fossil fuel	209	1 %	248	3 %
Peat	6334	22 %	1155	12 %
Black liquor and other concentrated liquors	233	1 %	*	*
Other wood fuels	5097	17 %	1457	15 %
Other renewables	334	1 %	200	2 %
Other energy sources	208	1 %	887	9 %
Total	29208	100 %	9750	100 %

Notes:

In addition to hard coal, coal includes blast furnace gas and coke oven gas and coke.
Mixed fuels (such as recycled fuel) are divided into renewable and fossil fuels in ratio to the fossil and biodegradable coal contained in them. Other fossil fuels include plastics fuels and other waste fuels and the fossil part of mixed fuels. Other renewable fuels comprise the bio part of mixed fuels and biogas.
Other energy sources include hydrogen, electricity, and reaction and secondary heat of industry.
Combined heat and power production includes pure combined production.
Reduction heat produced in connection with condensate production and combined heat and power production were calculated in separate production of heat.

Finnish Energy Industries^[2]^[3]:

Plant capacities in 2010:

There were 94 heat and power cogeneration plants that produced district heat. The total heat capacity of these was 7210 MW. Of these 94 plants, 10 were industrial plants (total capacity 350 MW).
There were 666 stationary distric heat plants, the total heat capacity of which was 13070 MW.
In addition, there were 392 portable district heat plants, the total capacity of which were 1400 MW.
