Supply to York Region - Parkway Transformer Station and Line Project
 The
growing need for electrical supply in the Greater Toronto Area and specifically
in the communities of Richmond Hill, Markham and Vaughan requires Hydro
One to reinforce our existing electricity transmission facilities in southern
York Region. The timing for the placing in-service of the transmission
line and most transmission station facilities is also linked to ensuring
reliable electricity supply to the Greater Toronto Area after the shutdown
of Lakeview Generating Station in April, 2005.
Hydro One and the local electric utilities in York Region have worked
together on a transmission solution that will increase electrical transmission
capacity, improve power reliability and reduce power losses.
The proposed facilities involve the construction of a transformer station
and a transmission line running parallel to existing lines, both on the
existing Parkway Belt hydro corridor.
- The new transformer station (Parkway TS) is now being constructed
on the southwest corner of Warden Avenue and Highway 407 in Markham
- The new 6.5-km transmission line is now being constructed from Parkway
TS to the existing Richmond Hill TS just west of Bayview Avenue in Richmond
Hill

Utilities
Hydro One worked with local utilities (Aurora Hydro, Hydro Vaughan,
Newmarket Hydro, Markham Hydro and Richmond Hill Hydro), to ensure
continued reliable electricity supply to York Region communities.
The results of their cooperation are available in the joint
planning study (PDF 1.2 MB).
Local Elected Officials and staff
Hydro One met with staff at Municipal and Regional levels to discuss
this project. Elected officials in Markham were also briefed on
the project.
Public Information Centre
Hydro One held a Public Information Centre on November 25 at the
St. Robert Catholic High School in Thornhill, centrally located
within the project study area. Through a series of information
panels (PDF 3 MB), brochure
(PDF 130 KB), discussion and feedback forms, valuable input was
gathered on the project, including preferences on the line location
within the existing right-of-way and preferences on tower type.

Based on public input, steel
poles were selected as the tower type for the transmission line. The
recommended alignment for the new line was along the northern side
of the existing tower lines on the transmission corridor. |

Parkway Transformer Station
Construction of the Parkway Transformer Station began in March 2004,
and continues today. The first stage of the station is expected
to be in service by April 2005.
6.5 km Transmission Line
Construction of the 6.5-km transmission line began in May 2004 and
continues today. Construction stages include: access road layout;
access road construction; augering for tower foundation footings;
pouring tower foundation footings; erecting towers; and stringing
conductors. The line is expected to be in service by April 2005.
Stormwater and Habitat Management
The realignment of existing creeks and the construction of two stormwater
management ponds will result in effective stormwater management
and a net increase of fish habitat at the site.
