Faulty bolts discovered during a routine inspection of Manitoba Hydro’s 200-MW Wuskwatim hydropower project have forced the operator to temporarily shut down three turbine units.
Company officials said the weakened bolts were found in the turbines’ discharge rings after the units had been in service for about 8,000 hours, though what caused the bolts to weaken has yet to be discovered.
Repairs are not expected to take more than a few days, Manitoba Hydro said.
The US$1.34 billion plant is the utility’s newest, opening in July 2012. (1)
Wuskwatim was developed through a partnership between the Nisichawayasihk Cree Nation (NCN) and Manitoba Hydro called the Wuskwatim Power Ltd. Partnership (WPLP).
The plant will is operated by Manitoba Hydro, but NCN has an option to own up to one-third of the Wuskwatim project through its wholly-owned corporation, Taskinigahp Power Corporation, as per a development agreement signed by the parties in 2006.
