P.E.I. government to repair Hermanville turbine that lost blade in storm
CBC
Hermanville Wind Farm has been running at reduced capacity since the end of December after a storm took down a large part of a blade on one of its turbines.
Blair Arsenault, an operational engineer at P.E.I. Energy Corporation, said the incident with Turbine 3, or T3, is still under investigation but the damage could've been worse.
"The technicians have gone up the tower and everything is functional out in the hub and including the nacelle. So it's definitely repairable. We will need a new blade and we will need to do repairs to the nacelle."
He said T3 will likely be operational in late May or mid-June.
While blades are usually supposed to withstand storms, Arsenault says damage is not uncommon. In the almost nine years he's been with the company, he's seen many instances of this happening.
"So [at] East Point, for example, we've replaced five blades, and at Hermanville we've replaced two blades," Arsenault said, excluding the blades that were demolished in an explosive fashion in mid-June of last year.
The corporation had already ordered spare blades for its turbines before this incident. These parts, which were ordered in February of last year, are being prepared for shipping from India, where they are being made.
"It's a good idea to have spare parts so you can get your investment back up and running," he said.
Arsenault said that fall, winter and spring are the best in terms of electricity production in the province. He also said that if T3 was active, it would produce approximately one gigawatt of electricity per month.
As a result, the province is losing $90,000 per month of revenue from this turbine being down.
Although the turbine is still under warranty, Arsenault said the manufacturer won't be paying for the damage. He told CBC News why the warranty wouldn't cover the damage, but said that information is privileged.
Arsenault also said the province wouldn't be filing an insurance claim.
"Our deductible and waiting have grown in recent years to the point where you know insurance claim doesn't make sense for everything that happened at the farm," he said.
The Hermanville Wind Farm was constructed in 2013 and accounted for $20 million in contracts.
