Göteborg Energi has several heat supply production units. Different kinds of fuel are used, among them bio oil, recovered wood waste and wood pellets.

​Sävenäs boiler HP3 was built in 1985 as a clean coal boiler to produce heat for district heating. In years gone by, the boiler has been converted to produce heat with cheaper and renewable fuels. In 2004 HP3 was converted to a biomass boiler to burn wood chips. With rising electricity prices and the introduction of green certificates for biomass power, it became interesting with the conversion of HP3 for electricity generation. The conversion result, we get an additional 40 to 50 GWh of renewable electricity, which is a requested item from our customers. The conversion is also an investment that will strengthen the company’s environmental profile and contributes to Göteborg Energi’s vision.
