Alstom will upgrade the turbine at Ligga hydro power station for Vattenfall in Sweden


Alstom Renewable Sweden AB has in fierce competition been chosen by Vattenfall 
Vattenkraft AB to upgrade one of three turbines at the Ligga power station in 
Luleå River in northern Sweden. The Ligga power station has 327 MW of installed 
capacity and an annual production of 1 656 GWh, which corresponds to an average 
annual electricity consumption of 83 800 Swedish homes. 

Alstom Renewable Sweden AB will carry out a model testing in Vattenfalls 
turbine laboratory in Älvkarleby in Sweden. The model test is performed to 
verify the technical performance guarantees for the new hydro turbine to be 
delivered by Alstom to the power station. Alstom will also supply a new pilot 
bearing and oil pressure system to the hydro turbine. In addition to the new 
parts to be delivered, Alstom will also dismantle, rebuild and re-assemble 
existing equipment on the turbine.

“We have chosen Alstom as supplier for this important modernization project 
based on a combination of the technical solution offered and a competitive 
price”, says Christer Ljunggren MD for Vattenfall Nordic Hydro Power.

“We are proud to be selected as supplier for this turbine upgrade project and 
we look forward to a good cooperation with Vattenfall during the execution of 
the project”, says Bertil Ekström MD for Alstom Renewable Sweden AB.
