“We need to unbundle the services that are required to operate the grid reliably. This includes energy, capacity and other grid services,” said Barbara Ellard, the IESO’s Director, Markets and Procurement. “In this way, we’ll be able to send accurate price signals and let the market determine what the best solutions are to meet those needs. Meeting our system needs through open and competitive markets will encourage innovative solutions and ensure emerging technologies can compete with conventional ones on a level playing field.”
