TORONTO, Feb. 28, 2014 /CNW/ - The outlook for Ontario's bulk
electricity grid continues to be positive in the near term, the
Independent Electricity System Operator (IESO) said in its latest
18-Month Outlook. The report anticipates adequate resources to meet
demand throughout the summer of 2014.
Approximately 3,100 megawatts (MW) of new generation is expected to come
online during the report timeframe, almost all of it
transmission-connected renewable generation. This follows the recent
retirement of nearly 2,000 MW of coal-fired generation removed from the
system in December 2013 when the remaining units at Nanticoke
Generating Station ceased operation.
Meanwhile, demand on the bulk electricity system is expected to remain
flat, as economic and population growth is mitigated by demand
response, conservation and expanded embedded wind and solar
generation. During the outlook period, embedded generation will nearly
double, rising to an estimated 2,500 MW. While embedded generation does
not reduce end-use consumption, it reduces the need for grid-supplied
energy. In particular, solar generation contributes to lower summer
Demand response is another factor working to reduce summer peaks. Large
industrial consumers are playing a large role in that, by reducing
their use on what are expected to be the five peak days of the year.
Together, various demand management efforts reduced peak demand by an
average 1,200 MW during peak days last summer - with similar outcomes
expected during the summer periods.
"The IESO's role, as system operator, is to ensure reliability by
keeping the grid in balance, regardless of circumstances," said Bruce
Campbell, President and Chief Executive Officer of the IESO. "That
balancing process starts months - and years - ahead, including through
our forecasts and assessments in reports like the 18 Month Outlook."
The IESO issues 18-Month Outlook reports every three months. The reports
assess the reliability and operability of Ontario's power system. They
are designed to advise market participants about reliability issues,
assess potential adverse conditions that might be avoided through
adjustment or coordination of maintenance plans and report on
initiatives being put in place to improve reliability. The full report
