Safety issue idles wind turbine at Clay
Toledo Edison shut down a 900 kilowatt wind turbine installed at Clay High School in May because it is missing a trip switch that would prevent backfeeding of electrical energy to and from Edison's substation. The Direct Transfer Trip switch costs $200,000 ...Edison denied a request from the district for a temporary operating permit to run the turbine until the matter could be resolved. "We can't run that risk."

Toledo Edison shut down a 900 kilowatt wind turbine installed at Clay High School in May because it is missing a trip switch that would prevent backfeeding of electrical energy to and from Edison's substation.
"The turbine is perfect," said Dean Sandwisch, business manager for the Oregon City Schools District. "Edison is requiring a shut down switch that would stop the turbine from operating and backfeeding into the system in the event of an electrical mishap, such as a lightning strike. And we're working to accommodate Edison."
Backfeeding, technically known as "islanding" would be a "rare event," said Sandwisch.
