Hafslund E-CO AS is an integrated energy and infrastructure group that is wholly owned by Oslo City Council.

Merging with Eidsiva

On October 1, 2019, the companies in the Hafslund E-CO and Eidsiva Energi groups were merged. It strengthened the environments within both hydropower generation and grid operations. Hafslund E-CO's focus on start-ups and innovative electrification solutions has also been strengthened with Eidsiva Energi on the owner’s side.

Hafslund E-CO owns 57.2 percent of the jointly owned power generation company with E-CO Energi and Eidsiva Vannkraft. In addition to operating an annual production of more than 20 TWh, the new production company owns hydroelectric power plants which together produce more than 17 TWh, enough power to supply more than 2.2 million people. The power plants are in Oslo and the counties of Akershus, Østfold, Buskerud, Oppland, Hedmark, Sogn og Fjordane and Vest-Agder.

Network Operations

Hafslund E-CO has significant ownership in grid operations through its 50 per cent stake in Eidsiva Energi. Eidsiva Energi owns 100 per cent of the shares in Hafslund Nett, which will be merged with Eidsiva Nett into a new grid company with around 900,000 customers. The network area includes Oslo, most of Akershus and Østfold, as well as large parts of Hedmark and Oppland.
