Salten Kraftsamband operates the Daja, Fagerli, Lomi, and Sjønstå power stations on the Sjønstå River in Sulitjelma and the Forså, Langvann, Sundsfjord, and Oldereid power stations in Salten.

It also owns 58% of Rødøy-Lurøy Kraftverk and 60% of Nord-Norsk Vindkraft and part of Fauske Lysverk.

The municipalities had cooperated in building the power plants, but needed a separate company to transport the electricity.

The current structure of the company arose in 1975 with a merger of Salten Kraftlag.

In 2000 SKS tried to merge with Bodø Energi and Fauske Lysverk, but the fusion failed.
