Merritt Area Transmission (MAT) project

BC Hydro is building a new 138 kV transmission line, between the Highland and Merritt substations, by July 2014 in order to meet the increased demand for power in the Merritt area. This project also includes expansion of the Merritt substation and upgrades to the Highland substation.

About This Project

Demand for electricity in the Merritt area is growing. BC Hydro load forecasts have determined that significant electrical load growth is anticipated in this area. Contributing factors to this growth include development of new hotels, residential subdivisions, commercial areas and a resort south of Merritt in the Coquihalla corridor. To meet this increasing demand for power in Merritt, a new transmission line mst be in service by the end of 2014.

The Merritt Area Transmission Project will ensure Merritt's homes and businesses continue to have reliable electricity for the next 30 years. The project includes:

  • A new 35 kilometre above-ground 138 kV transmission line along mostly existing BC Hydro rights-of-way, between the Merritt and Highland substations.
  • Upgrading the Merritt Substation, including the addition of new equipment and small buildings, all within a new, expanded fenced area.
  • Adding new equipment at the Highland Substation.

Routing of the Merritt Area Transmission line was selected to be cost effective, minimize environmental impacts and allow the project to be built on time to meet Merritt's electricity needs in 2014.

Construction for the Merritt Area Transmission project began in the spring of 2013. BC Hydro had been carrying out engineering and environmental studies, and consulting with First Nations and key stakeholders to confirm the project design and transmission line routing. Consultation will continue to take place throughout construction.

Following completion of the Merritt Area Transmission project, BC Hydro will upgrade a portion of the existing transmission line in Merritt to support Merritt Green Energy, an independent power producer, to provide safe reliable electricity.
