The story

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.
