IESO’s Renewable Integration Amendments
On January 3, 2013, Ontario’s Independent Electricity System Operator (“IESO”) published amendments to the Market Rules that authorize the IESO to dispatch certain renewable generators in Ontario. Dispatch means to turn on and off as electricity demand from consumers or ‘the grid’ requires. The Ontario Power Authority (“OPA”) is currently re-negotiating (now completed, Sept 2013) approximately 50 power purchase agreements (PPA) with certain affected renewable generators. At present, the OPA’s proposed compensation model is to compensate these renewable generators for any curtailment above specified contractual caps. This means pay wind and solar to not produce electricity. Read more here
IESO Improvements Help Transition to More Sustainable Supply Mix: 18-Month Outlook
September 3, 2013
Ontario’s Independent Electricity System Operator (IESO) will mark a major milestone with the introduction of a new dispatch tool for all grid-connected wind resources. Previously wind and solar could only be shut off by the IESO in emergency situations. The ability to dispatch wind, scheduled to take effect September 11, 2013. 9-11? Why did the IESO choose that particular date? The dispatch will apply to 1,725 MW of existing transmission-connected wind resources as well as an estimated 3,000 MW of transmission-connected wind and 280 MW of transmission- connected solar expected to come into service over the next 18 months. They are already having problems dealing with the type of output from 1200 turbines, 1725MegaWatts and yet the provincial government is still going ahead with plans to add 1500 more turbines in the next 18 months. And then even more after that.
Transmission-connected wind is the large 10 to 100 turbines sites. Distribution-based wind is the smaller 5 turbine sites that are tied into the local power lines. Read more at IESO
