Second Province-Wide Activation of peaksaver(R) in Less Than Two Weeks Demonstrates Value of Conservation

    TORONTO, July 18 /CNW/ - peaksaver, a residential and small business
electricity demand reduction program that temporarily powers down central air
conditioning systems has demonstrated its value as an active conservation
measure again-less than two weeks after its first use on July 7th.
    Activated for the second time provincewide today, peaksaver is helping
Ontario actively manage its demand for electricity, forecast this morning to
be the highest so far this summer. It's estimated that the program, designed
and administered by the Ontario Power Authority (OPA) and co-ordinated by the
Independent Electricity System Operator (IESO), could potentially save up to
45 MW today. This would be equal to the peak electricity requirements for more
than 11,000 homes. The OPA expects that peaksaver will be activated up to
10 times this summer to mitigate peak demand on Ontario's electricity system.
    "Everyone in Ontario benefits when peaksaver is activated: it reduces
system strain by helping to keep summertime demand in check," says Director DR
and Industrial Programs Sean Brady. "peaksaver is a flexible and valuable
electricity demand management resource for Ontario. We encourage any homeowner
or small business person with access to the program who has not done so
already to sign up today."
    With peaksaver, participating homeowners and small businesses agree to
have a device (thermostat or switch) installed to allow a wireless signal to
temporarily cycle air conditioning on and off with minimal impact on comfort
levels; they receive $25 to have the device installed and the overall system
saves money as a result. The program is offered by 47 local electricity
distribution companies (LDCs) across the province. More than 90,000 homes and
businesses have signed up so far.
    Residents who participated in targeted activations of peaksaver last
summer reported that they hardly noticed when a cycle-down had taken place.
During the four-hour period when an activation has occurred there is only a
very small rise in temperature because air conditioners are only turned down,
not off entirely. With some participating LDCs, peaksaver can also be applied
to reduce the power consumed by electric water heaters in homes with central
air conditioning.
    Peaksaver is complemented by three other OPA programs supporting the
residential sector and the OPA has several other business focused programs;

    By the end of this year, the OPA expects to be offering 26 conservation
programs in total. As part of the OPA's Integrated Power System Plan (IPSP),
it has been proposed that Ontario invest $10.2 billion in conservation over 20

    The OPA is responsible for ensuring a reliable, sustainable supply of
electricity for Ontario. Its four key areas of focus are: planning the power
system for the long term, leading and co-ordinating conservation initiatives
across the province, ensuring development of needed generation resources and
supporting the continued commercial evolution of the electricity sector.
