The refurbishment and expansion of the Akkats hydro power plant near Jokkmokk, Sweden, is Vattenfall’s largest hydro power project in 20 years.
The power plant, which was built on the river Lule älv between 1969 and 1973 with a 150 MW turbine, is now being retrofitted with two turbines each with 75 MW of installed capacity. With two turbines, sensitivity to operational disruptions will be decreased, and annual electricity generation is expected to increase by approximately 26 GWh to approximately 590 GWh.
The project is scheduled for completion in 2016. The investment sum is estimated at approximately SEK 1.2 billion.
