The first phases of refurbishment works at Ffestiniog Power Station, part of the 2 GW First Hydro pumped storage operation in Wales, have been completed, says ENGIE. 

The £50mn refurbishment programme involves replacement of two 90 MW generating units, extending their operational life for at least a further 20 years. 

Both original units were disassembled, providing the first access to the lower bearings and turbine, revealing substantial corrosion and confirming ENGIE’s decision to refurbish. 

In addition, one of the two 200 m deep vertical hydraulic shafts is being refurbished, a new 2.7 km power supply to the upper reservoir has been installed and safety systems have been upgraded.
