Grid operators were able to integrate a record amount of wind power last year without significant cost increases or destabilizing their systems, according to Michael Goggin, manager of transmission policy at the American Wind Energy Association. Critics of renewable energy "have said for years that costs would go up and the grid would fall apart. They have been proven wrong," Goggin said. "Newer research suggests systems can go to 40 percent renewables with no problem, using the very efficient grid operating practices being applied" by the Midwest ISO and others, Goggin said.
