The stator of the Raasakka hydroelectric power plant’s second generating unit will be replaced in 2023. The investment is part of PVO-Vesivoima’s long-term modernisation programme and will strengthen the Raasakka power plant’s production and control capabilities.
PVO-Vesivoima has decided to invest in a replacement stator. The new stator will be installed in the power plant’s second generator, replacing the 1970s original.
“The stator of the second generator of the plant’s three units has shown signs of degrading, so a new stator will be installed next year. This is a replacement investment that will ensure reliable, uninterrupted, and energy-efficient electricity production at the Raasakka power plant in accordance with our modernisation programme,” says Juha Kähkölä, PVO-Vesivoima’s development manager.
The new stator is due to be installed in the summer and autumn of 2023. The stator is supplied by the Spanish company Indar, part of Ingeteam Group.
