Steingríms Power Station is the third station built in the River Sog area. The station harnesses the head where the Upper Sog drains from Lake Þingvallavatn into Lake Úlfljótsvatn. A dam was built at the outflow of Lake Þingvallavatn, with the headrace tunnel running through Dráttarhlíð, which separates Lake Þingvallavatn and Lake Úlfljótsvatn, and into an open-air surgepond above the powerhouse. The outflow from Lake Þingvallavatn is on average approximately 100 m3/s.

The station came on-line in 1959, and the installed capacity is 26.4 MW.

Third largest power station in the Sog area

Steingríms Power Station came online on 6 August 1959 and located at lake Úlfljótsvatn.
