The Henvey Inlet Wind farm project is well underway and now visible at the laydown yard at the Oastler Lake exit off the 400. OLRA asked several questions of Jody Law, Sr. Manager, Business Development, Pattern Energy and received these answers Nov. 22, 2017
- Does Hydro One Networks Inc. (HONI) need to bring forward a leave to construct (LTC) application for the tap line that would be reviewed by the Ontario Energy Board? No – only Henvey Inlet Wind needs to do this as owner of the line.
- Were there any mitigation measures to deal with the visual pollution from the switching station noted in your environmental assessment (EA)? No, other than a commitment to minimize the amount of disturbance to existing vegetation, where possible.
- If there are no mitigation measures noted in the EA, what mitigation measures will Henvey Inlet complete to minimize the visual pollution around the 230-kV and switching station particularly from Little Otter Lake? No concrete mitigation measures have been finalized to date; however, we will continue to consult with affected stakeholders, including the Otter Lake Ratepayers’ Association, on this issue.
- The 230-kV tower on the hill above the Foley Matheson Park is higher than the 500-kV towers of either side. Does that mean that the tap line poles and wires, once under the 500-kV lines will go up to this higher 230-kV tower? Not yet finalized (these structures are part of HONI’s scope) but, generally, tap structures are not as high as the towers to which they are connecting.
- Where is the final location for the switching station? Henvey Inlet Wind has severed and purchased from the Municipality a piece of land off Garden Court Road, just at the final curve before the road heads down to the cottages. From the perspective of Little Otter Lake, the station will be situation behind the existing HONI transmission lines.
- When will the engineering/design work be completed for the switching station? Early 2018
- When will the engineering/design work be completed for the tap line? This is in HONI’s scope, but we anticipate early 2018 as well.
- What will the switching station look like, including what it will look like from the water? TBD
- What will the tap line that will connect the Henvey Inlet transmission line to the 230-kV tower look like, including what it will look like from the water? TBD
- When will clearing start for the switching station? Clearing will occur over the 2017/2018 winter. Exact timing is not yet known, but likely Q1 2018.
- How long will the clearing and subsequent construction to build the switching station take? At this time, we expect all construction on the switching station to be completed by Q4 2018.
- When will the Henvey Inlet transmission line be completed? At this time, we expect construction of the transmission line to be completed by Q4 2018.
- When will the Henvey Inlet transmission line be in-service? At this time, we expect the wind farm and transmission line to be in-service starting in Q1 2019.
- Can neighbours expect to hear any noise from the switching station and/or tap lines when the transmission line is in service? No. There are not transformers or sound-generating equipment at the switching station.
