Participant News

The next baseline implementation of market changes on September 12 will include a change in the ramp rate multiplier to three times from the current 12 times ramp rate.

The IESO is moving to a three times ramp rate multiplier to improve the quality of market signals to all consumers and producers by making the energy price more closely reflect the cost of producing electricity in real time.  

As part of the implementation, over the next 18 months the IESO will review the effect of the ramp rate change as compared to the forecast system benefits.
