text: Toronto Star; Coping with surplus wind power will cost Ontario electricity ratepayers up to $200 million a year if market rules don't change, says the power system operator. Moreover, it says, if it can't control the flow of wind and solar power onto the Ontario grid, then "reliable and economic operation of the power system is, at best, highly compromised and likely not feasible." When there's more power than the system can handle, the IESO sells it to neighbouring provinces and states -- sometimes at a loss, and sometimes actually paying them to take it. No worries, there's plenty of wood in the Greenbelt . h/t AK
