The IESO introduced a new system on 11 September requiring wind and other renewable producers to respond to dispatch instructions from the system controller every five minutes, just like conventional generating technologies. Previously, the IESO was required to accept all energy produced by wind facilities. This created challenges at times when the province already had more base-load generation than it could use or sell into other markets, said IESO spokesman Jordan Penic. "When that happens something has got to give," he says. Typically, the default was to curtail nuclear generation. But once a nuclear unit goes down, it takes 72 hours to ramp back up again, requiring the IESO to buy costlier gas generation to pick up the slack in the interim.
