Ontario Power Generation (OPG) has launched a 16-year overhaul of the 1045MW R.H. Saunders Generating Station, the second-largest hydroelectric project in Ontario, Canada. The project began in January, with the first of the station’s 16 units, G9, now fully disassembled, with refurbishment set to be completed by early 2024. The overhauls of the rest of the station’s units will occur each subsequent year until the project wraps up by around 2039.
