Hydro One Networks Inc. is asking the Ontario Energy Board for permission to reconductor approximately 11.9 kilometres of single circuit 230 kilovolt transmission lines (known as M30A and M31A circuits) from Hawthorne Transmission Station to Merivale Transmission Station, in the Ottawa area. If the application is approved as filed, Hydro One Networks Inc. will reconductor the M30A and M31A circuits with a dual-bundled (two conductors per phase) circuit configuration. The M30A and M31A circuits currently consist of 3 phases each and with each phase consisting of a single conductor.
Hydro One is also asking the Ontario Energy Board for approval to perform related work at the two transmission stations and to approve the form of agreement it offers to landowners to use their land for routing or construction of the proposed line.
A map of the proposed route for the transmission line is provided in the notice below.
