Renewable Energy Integration in Ontario: An Update

  • In the absence of more-flexible nuclear output, surplus baseload generation would cause renewable energy to be dispatched off.
  • With Bruce Power’s apparent 2,400 MW of CSVD flexibility, renewable energy will still have to be dispatched off.
  • At the end of 2015, hourly scenarios exist whereby wind could produce up to 6,500 MW - with none effectively consumed in Ontario but at a cost to Ontario ratepayers of $705,000."
Aegent previously discussed the challenge presented by integrating renewable energy – particularly wind – into Ontario’s electricity grid. The highly variable nature of wind output is an ever-present challenge and while installed wind capacity is on the rise, flexible coal-fired generation is being taken out of service and being replaced by a much less flexible natural gas-fired fleet.
Ontario’s Independent Electricity System Operator (IESO) has an ongoing stakeholder engagement process (SE-91) that deals with the issues related to renewable integration. With more and more renewables coming online, the SE-91 process is ramping up. As the process moves forward, it is becoming increasingly clear that a key strategy for incorporating renewable is to implement mechanisms for paying generators not to generate.
