IESO's 18-Month Outlook Available Online

June 28, 2012
The IESO 18-Month Outlook for June 2012 to November 2013 is now available. The report, which assesses the adequacy and reliability of Ontario's power system, states that the province is expected to have an adequate supply of electricity to handle the increased demand resulting from air conditioning use over the summer, even under hotter than normal weather conditions.
 
Approximately 1,500 MW of nuclear generation and 500 MW of renewable generation will be added to the high-voltage grid during the reporting period. By November 2013, total wind and solar generation connected to the transmission and distribution networks in Ontario will reach approximately 3,800 MW.
 
The double-circuit Bruce to Milton transmission line is now operational and can accommodate the full output from all eight generating units at the Bruce nuclear complex as well as the additional renewable resources planned in southwestern Ontario.
 
Economic growth in Ontario is expected to result in a modest increase in electricity consumption which will be partially offset by conservation initiatives and increased embedded generation. Total consumption is expected to rise by 0.1 per cent in 2012. Peak demand is expected to remain flat over the forecast period due to increased embedded generation, conservation measures, and the impact of time-of-use rates and other demand response initiatives.
 
New sources of generation continue to be brought into service to meet future supply needs and replace coal-fired capacity. The incorporation of this supply, coupled with declining demand during off-peak periods, has caused periods of surplus baseload generation which the IESO will continue to manage.
 
The IESO regularly assesses the adequacy and reliability of Ontario's power system. The 18-Month Outlook is issued on a quarterly basis (www.ieso.ca/18-month.outlook.jun2012). For the IESO News Release, please see: http://www.ieso.ca/imoweb/media/md_newsitem.asp?newsID=6112.
