Ontario Power Authority Recommends Moving Forward on Power Corridor

    Bruce to Milton Transmission Line Key to Ontario's Long Term Power

    TORONTO, March 26 /CNW/ - In a letter to Hydro One, the Ontario Power
Authority (OPA) has recommended commencement of the planning and approvals
process required to build a new 500 kilovolt transmission line to deliver
renewable and nuclear power from the Bruce region to Ontario's electricity
    The OPA has indicated the optimal route for the new line is adjacent to
an existing transmission line from the Bruce Power facility to the Milton
switching station, a distance of approximately 180 kilometers. In keeping with
provincial land use policy, the preferred route follows an existing right of
way. With this route, the system will accommodate 1,000 MW more power than the
next best alternative.
    The existing transmission line has the capability to transmit enough
generation from the Bruce area to Ontario's electricity consumers to meet
today's needs. The new line will provide transmission capability to reliably
and safely deliver an additional 3,000 MW of generation capacity.
    Bruce Power is returning to service two nuclear units by 2009. These
units have been out of service since the mid 1990s. Approximately 700 MW of
wind development projects have also been identified in the Bruce area to date,
with another 1,000 megawatts of future renewable energy potential in the
    The OPA's analysis looked at various options to increase the capacity of
the electricity transmission system in southwestern Ontario to meet this need.
The final recommendation considers technical requirements, total system
capacity, provincial land use policy and the overall cost to Ontario
electricity consumers.
    In December, 2006, the OPA called on Hydro One, working with the
Independent Electricity System Operator and Bruce Power, to institute interim
measures by 2009 to maximize the capability of the existing system to the
extent possible until the new line is in service.

    In pursuit of its mandate of ensuring an adequate, long-term supply of
electricity for Ontario, the OPA creates and implements conservation and
demand management programs, ensures adequate investment in new supply
infrastructure, performs long-term electricity system planning, and
