Longlac TS is an existing Hydro One, two 25/42MVA, 115/44kV transformer station located in Geraldton, Northwest Ontario. To accommodate the upcoming Hardrock Project, the Longlac TS will be relocated to a mutually agreeable new location between Hydro One and Greenstone Gold Mines.
In accordance with Hydro One’s latest requirements, standards and best practices, the scope of work of our team include the station design, procurement support, and contract management of Longlac TS.
GGM mandated our team to complete the detailed engineering for this greenfield station, including Environmental, site preparation, protection & control, metering, teleprotection, electrical arrangement, telecom and project management. In addition to design and engineering responsibility, we were mandated to manage the site construction contract for installation and pre‐commissioning to the point of transfer of responsibility to Hydro One.
