Ontario ’s power system is prepared to meet the province ’s expected demand for electricity over the coming summer months , accord to the Independent Electricity System Operator ’s ( IESO ) latestReliability Outlook .
“ Our arrangement remains reliable as we head into the summer , with adequate resources to supply the electrical energy needs of homes and businesses across the state , ” says Leonard Kula , the IESO ’s Chief Operating Officer . “ Maintaining the reliability of the state ’s electricity arrangement on behalf of all Ontarians is at the core of what we do , and we are well equipped to manage potential operational challenges resulting from potential uttermost weather this summertime . ”
The Reliability Outlook includes prefigure electrical energy demand and scheme adequacy over the next 18 - calendar month period , and includes an extended 42 - month outlook to leave transparence into the future electrical energy penury of the province .

The trend of flat provincial electrical energy demand over the past decade is ask to uphold over the next 18 months . Ontario will , however , receive some localized need growth as a upshot of regional economic activity . electrical energy exercise in the Windsor - Essex region is expected to reduplicate over the next five twelvemonth due to strong agricultural growth , in the first place from expansion in the greenhouse sector . The IESO recently requested the development and expression of new transmissioninfrastructurein the Windsor - Essex arena , to help support future electrical energy want .
The extended five - twelvemonth mind-set identify a potential content need beginning in the summer of 2020 , with that need uprise large in 2023 – a time when long - term contracts with contemporaries facilities commence to expire , and nuclear unit are being refurbish or retired . Ontario ’s capacity requirements throughout this period are bear to be meet using resources such as need response , imports , generator that are coming off long - term contract , enlargement of existing facility and energy efficiency measures .
free-enterprise auctions in 2020 and beyond will address the growing electrical capacity need , providing an chance for these resource to vie in Ontario ’s electrical energy market . This is part of aMarket Renewal programthat will achieve approximately $ 3.4 billion in saving for Ontario residents and business over a ten yr period of time .
The IESO will be updating its forecast and will release a new annual provision written document this September , which will outline Ontario ’s succeeding electricity needs for the next 20 years .
