# Østfold Energi

Østfold Energi is a Norwegian energy producer within the business areas of hydropower, wind and heat. The company operates hydroelectric power plants in Østfold and Sogn og Fjordane with an annual power production of 1,680 TW·h/year.

In 2009 Østfold Energi, together with Nord-Trøndelag Elektrisitetsverk, purchased Siso and Lakshola power plants in Nordland county. Combined production at the power plants totals around 1 TWh. This acquisition brings Østfold Energi’s share of Norway’s total hydropower production to around 1.7 per cent.
Østfold Energi is co-owner of Kvalheim Kraft DA who owns and operates the windmill park Mehuken in Sogn og Fjordane on the west coast of Norway. The wind farm was opened in 2001 with five wind turbines. In 2010 the wind farm was extended with additional eight wind turbines. The annual production of electricity is now 65 GWh. The approximately 3,000 households in the Vågsøy municipality are now self-supported with electricity from the wind turbines at Mehuken.
Østfold Energi owns and operates two modern waste-to-energy plants. The plant in Sarpsborg converts waste residue (house refuse and industrial waste) into thermal energy (process steam) to Borregaard. The plant in Rakkestad provides process steam and district heating to nearby industrial companies. Totally 181 GWh thermal energy was produced at the waste-to-energy plants during 2010.
The company also holds ownership of Zephyr (33%), Norsk Grønnkraft (25%), Kvalheim Kraft (33%), Rygge sivile lufthavn (15%) and Hafslund (4.5%).

In 2014, Østfold Energi sold its shares in EfW heat provider, Hafslund ASA. The managing director Oddmund Kroken said, the energy firm will use the cash to invest €30.7m in other renewable energy projects.

## History

The company was created through the 1960s to the 1980s as a merger between the municipal owned power companies throughout Østfold, with only five municipalities not joining. Until 1997 the company was named Østfold Energiverk.
In 2000 49% of the grid and retail subsidiaries were sold to Swedish Sydkraft, and in 2003 Sydkraft took over the distribution, installation and retailing subsidiaries while the power production was left in Østfold Energi. The same year Sydkraft swapped its ownership to Fortum in a business deal.
