TORONTO, June 22 /CNW/ - In its latest 18-Month Outlook released today,
the Independent Electricity System Operator (IESO) indicated that under normal
weather conditions and with the planned resource additions, there should be
sufficient resources available within the province to meet expected
requirements during most of the period covered by the Outlook.
However, as in past summers, Ontario may need to rely on power from
neighbouring jurisdictions on some occasions, particularly if extreme weather
occurs or if equipment performance is below normal.
"With generation reserves forecast to be less than required in some
weeks, extremely hot and humid weather conditions could put the system under
significant stress," said Derek Cowbourne, IESO Chief Operating Officer.
More than 2,300 megawatts (MW) of new supply is expected to come into
service over the next 18 months. The new supply includes over 1,500 MW of new
gas-fired generation and over 700 MW of new wind generation. The majority of
this new capacity is expected to come into service during the last three
months of the study period.
"The 2,300 MW of new generation scheduled to come into service represents
the highest amount of additional capacity in any 18-Month Outlook period since
2002," said Cowbourne.
Conservation and demand response programs offered by the Ontario Power
Authority and local distribution companies continue to gain traction and will
grow moving forward. This Outlook includes the anticipated effects of those
conservation and demand response programs. The announced delays to the Goreway
generating station in Brampton have also been incorporated in this 18-Month
The Ontario transmission system is expected to be adequate to supply the
2007 and 2008 demand under forecast conditions.
