The future of the district heating sector

Demand and market share of district heat 2010 - 2025

2010• Market share of district heat 45%• Demand for district heat 36 TWh

(temperature-corrected demand)

2025• Market share of district heat in new

construction 2011–2025 50–75%• Demand for district heat 40–42 TWh

Production of district heat, CHP 2010–2025• New heat capacity 1,500 MW

– of which CHP heat 0–1,000 MW (CHP electricity 0–500 MW)– new heat capacity 500 MW, the rest is substitutive

• If the max. number of CHP plants is realised– Additional heat production 4 TWh, electricity 2 TWh– Savings in primary energy 14‒27% (note! part of the additional

production will substitute old CHP production)
