Miller Creek
The Miller Creek facility is a 33 MW, two-unit run-of-river hydroelectric power plant located on Miller Creek, near Pemberton, British Columbia. It is wholly owned by Capital Power and consists of a 30 MW main unit and a 3 MW unit for peaking and use during the low-water creek flow season. Both units were commissioned in 2003. The facility is located on Crown land leased by Capital Power. Capital Power pays water rental fees to the Province of British Columbia for the use of water.
The Miller Creek powerhouse contains one 29.5 MW vertical-axis Pelton Wheel turbine and one 3.3 MW horizontal-axis Pelton Wheel auxiliary turbine. The facility has an automated control system to allow unattended operation, remote monitoring and remote control of the project, which helps reduce its operating costs. Water flows on Miller Creek peak from May through August, with relatively low flows in the winter months. Power is sold to BC Hydro, a British Columbia Crown corporation, which has the same S&P credit rating as the province: AA+.
Brown Lake
Brown Lake is a 7 MW hydroelectric power plant located on the Ecstall River, near Brown Lake and Prince Rupert, British Columbia. The plant was commissioned in 1996 and purchased by Capital Power in 2000. In addition to water rental fees paid to the Province of British Columbia, a royalty, which ends in 2034, is paid to one of the original developers. Power generation from the facility is generally consistent throughout the year, with the exception of July and August when water flows and the resulting electricity generated are usually lower. The facility is located on leased Crown land.
The Brown Lake plant uses water flow from two lakes: Brown Lake and McKnight Lake. The powerhouse contains a single horizontal Francis turbine-generator.
Capital Power is party to a 20-year term EPA with BC Hydro, ending December 2016, for all of the power output from the facility.
