In 1952, we started out our mission towards an energy system with high efficiency and low environmental impact

  • In total, our district heating system supplies more than 60% of the heating demand

  • in Göteborg



District Heating Gothenburg

- environmental advantages in three dimensions

  • Local: Improved urban air quality (Particles, SO2, NOx,)

  • Regional: Reduced acidification (SO2, NOx),

  • Global: Reduced emissons of greenhouse gases (CO2)

    Reduced consumption of resources


Linked environmental impact climate change and resource efficiency

Rya combined heat power plant
Rya Combined Heat & Power Plant future

  • Fired by natural gas, and with diesel as reserve fuel

  • Future transfer to gasified biofuel possible

  • Construction began in 2004. The plant was taken over in december 2006

  • Investment amounts to SEK 2 billion

  • Ensures the supply of electricity for important social functions in Göteborg

  • 35 % of Göteborg’s heat requirements are met using district heating from the Rya Combined Heat & Power Plant

  • 30 % of Göteborg’s electricity requirements are met using electricity produced by the Rya Combined Heat & Power Plant


Technical data for the plant future

  • Maximum fuel input 600 MW

  • Electric output 261 MW

  • Heat output 292 MW

  • Total efficiency 92,5 %

  • Operating time 4000 h

  • Electricity prod. 1250 GWh

  • Heat prod. 1450 GWh

  • NOx 10 mg/MJbr

  • Ammonia slip 5 ppm

  • Black start & ”Island mode operation”
