TORONTO, Feb. 6, 2012 /CNW/ - The Independent Electricity System
Operator (IESO) is planning a routine voltage reduction test for
tomorrow, Tuesday, February 7, 2012. The IESO performs voltage
reduction tests every 18 months to simulate emergency actions and
measure the load reduction that occurs.
The IESO is working closely with transmitters and local distribution
companies to prepare for the voltage reduction test, which will
comprise two separate exercises. A three per cent reduction in voltage
will take place from 9:00 a.m. to 10:00 a.m. EST, while a five per cent
reduction will take place from 1:00 p.m. to 2:00 p.m. EST.
"Voltage reductions are an important tool to help us maintain the
reliability of Ontario's power system," said Kim Warren, Vice-President
of Operations and Chief Operating Officer of the IESO. "Should demand
for electricity exceed available supply, a voltage reduction can lower
demand quite quickly and minimize the likelihood of service
Consumers should not notice voltage reductions as supplied voltages are
still expected to be within established industry standards for
electrical equipment. Consumers with questions about the test should
contact their local distribution company. A list of local distribution
companies is available at www.ieso.ca/findutility.
More information about voltage reductions is available on the IESO
website at www.ieso.ca/voltagereduction or by contacting customer relations at 1-888-448-7777.
The IESO is responsible for managing Ontario's bulk electricity system
and operating the wholesale electricity market. For more information,
