Stornorrfors Hydroelectric Power Station (Swedish: Stornorrfors kraftverk) is a hydroelectric power station on the Ume River in Västerbotten County, Sweden.

The city of Umeå lies about 15 km southeast of the power station.

Prior to the construction of Stornorrfors, the Klabböle Power Plant supplied power to the city of Umeå several kilometers downstream from Stornorrfors.

[1] It generates more electricity per year than any other hydroelectric power plant in Sweden and is the country's second largest in power production.

A canal connects the reservoir with the power station.
