Surplus wind power could cost Ontario ratepayers up to $200 million: IESO | Toronto Star

Surplus wind power could cost Ontario ratepayers millions and compromise power system, says electricity system operator. It says renewable energy market rules must change

Duane Tilden‘s insight:

“It is not unusual for the wind to fall off in the morning at the same time as the morning load picks up,” says the IESO.

 

At present, the IESO can’t control the flow of wind and solar onto the system in the same way it can control the output of other generators. It all flows onto the grid, and is paid a fixed price.

 

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.
