Värtaverket CHP plant
Central Stockholm is the location of one of Europe’s largest district heating and cooling systems. The newable energy is enough to heat 190 000 apartments and to generate electricity for 150 000 electric vehicles.
The Värtaverket plant is a familiar feature of the Stockholm skyline. From 2013 to 2016 the construction of a new biofuelled CHP plant was underway for the new Värtaverket - one of the largest bio CHP plants in Europe.
The heat from Värtaverket is produced mostly by combined heat and power and/or heat pumps. Värtaverket’s combined heat and power plant uses coal and biofuels to produce heat and electricity, with fuel and ash processed in an entirely closed system in order to minimise problems with dust, noise and smell. The heat pump facility at Ropsten produces heat using natural cycles. Värtaverket produces 2,598 GWh heat, 526 GWh electricity and 304 GWh cooling per year.
Fortum invested SEK 4.4 billion in the facility at Värtan. The biomass CHP plant involves a comprehensive modernisation of Stockholm's district heating provisioning and will help reduce CO2 emissions in Stockholm by an estimated 126,000 tonnes annually.
The CHP plant produces 1,700 GWh heat and 750 GWh electricity per year, which is equivalent to heating of approximately 190,000 average size apartments. The facility therefore makes a significant contribution to the City of Stockholm in meeting its climate targets and will be an important step in the development of a sustainable energy supply in Stockholm and Europe.
