Peace Region Electricity Supply

What's new

Construction of the Peace Region Electricity Supply (PRES) Project is underway.

We've cleared the route for the transmission line and we're installing the required upgrades at the substation sites. We're also upgrading and developing access roads where they're needed for construction. We have also recently awarded the contract for transmission line construction to Voltage Power and they'll be starting transmission line construction in summer 2019.

Safety is our top priority. We ask hunters, trappers, and recreational and other users to use caution along our power line route. Please watch for signs that indicate active work areas and don't hunt, shoot, or set traps in areas where construction could be planned or occurring,

We're building two parallel 230 kilovolt power lines between the Site C Substation that’s under construction near Fort St. John and the existing Groundbirch Substation, located about 30 km east of Chetwynd.

We are also completing upgrades at both substations, building new access roads and upgrading existing access roads.

Electricity demand in the South Peace Region is increasing as a result of natural gas exploration and development in the area. There is significant potential load growth and the existing transmission infrastructure is reaching capacity.

PRES will increase the capacity of the transmission system that supplies the South Peace Region and improve service reliability.

PRES will also help to ensure that we can reliably provide electricity to our industrial customers who want to power their facilities with clean energy.

The 58-kilometre long transmission line route is located between the Site C Substation that's under construction near Fort St. John and the existing Groundbirch Substation, located about 30 km east of Chetwynd.

PRES will help reduce greenhouse gas emissions by enabling customers to use clean electricity rather than fossil fuels to power their equipment and operations.

Our route is located on Provincial Crown land. In June 2018, the Province (Ministry of Forest, Lands, Natural Resource Operations and Rural Development) granted BC Hydro a Licence of Occupation to start construction of the PRES Project. Thereafter, other associated Project construction permits and authorizations were obtained in accordance with the Land Act, Wildlife Act, Water Sustainability Act, and the Heritage Conservation Act.

Construction began in the summer of 2018 and we expect to put the project into service in late 2021. Remediation and reclamation will continue for another one to two years after the in-service date. The schedule moving forward is shown below.

Safety is our top priority. We ask hunters, trappers and recreational and other users to use caution along our power line route. Please watch for signs that indicate active work areas and don't hunt, shoot or set traps in areas where construction could be planned or occurring.

We prepared a Construction Environmental Management Plan for the project. This plan includes requirements for protection of the environment, including environmental monitoring and environmental compliance auditing during construction and restoration. Activity-specific Environmental Protection Plans have also been developed.

Thanks to all of you who have provided feedback to us so far. We'll continue to work with First Nations and local communities and update you as project construction advances.
