Converted from coal to sustainable wood pellets, Studstrup heat and power plant is one of the largest biomass-fuelled power stations in the world, providing enough power and heat for hundreds of thousands of Danish homes.

Studstrup heat and power plant also consists of the coal-fired unit 4, which can generate 360 MW of electricity. On 1 October 2022, the Danish authorities decided to order Ørsted to resume operations of three of its power station units which use oil and coal as fuel, in order to ensure the security of the electricity supply in Denmark. Unit 4 at Studstrup is one of the units to resume operations until 30 June 2024.

Location: Nordhavn, Copenhagen

Heat-generating capacity: 256 MJ/s

Fuel: Natural gas

In operation since: 1953

Converted from coal into oil and gas in 1994, and to gas alone in 2014

Originally built to supplement heat and power production at H.C. Ørsted CHP on the other side of central Copenhagen, Svanemølle is now a heat plant which supplies around 6000 homes with district heating. 

Location: Hornsherred, Zealand

Power-generating capacity: 404 MW

Fuels: Diesel, natural gas

In operation since: 1940

Kyndby power station provides emergency and peak-load electricity for the island of Zealand. That means it can be started up within minutes if there are problems elsewhere in the grid.

Kyndby power station also consists of the oil-fired unit 21, which can generate 260 MW of electricity. On 1 October 2022, the Danish authorities decided to order Ørsted to resume operations of three of its power station units which use oil and coal as fuel, in order to ensure the security of the electricity supply in Denmark. Unit 21 at Kyndby is one of the units to resume operations until 30 June 2024.

Location: Northwich, Cheshire, northwest England

Power-generating capacity: 3 MW

Waste-processing capacity: 80,000 tonnes per year
