Waneta Dam Expansion is a two-unit powerplant which started construction in winter of 2010/11 just downstream of the existing Waneta Dam on the Pend d'Oreille River. The dam generates power from water that would otherwise be spilled from the existing project, and is delivered to the BC Hydro grid via a separate 10 km long 230kV transmission line. The expansion project is a partnership, with Fortis Inc. holding a 51% share in the project and the two Crown agencies Columbia Power Corporation and Columbia Basin Trust holding a 32.5% and 16.5% share, respectively. SNC-Lavalin designed and built the project. In January 2019, Columbia Power and Columbia Basin Trust announced that they had agreed to purchase Fortis Inc.’s 51% interest in the facility. The purchase was concluded in April 2019.
The project started delivering power to the grid in 2015 [3] via its two Francis turbine-generator units [4]
The British Columbia Hydro and Power Authority, operating as BC Hydro, is a Canadian electric utility in the province of British Columbia. It is the main electricity distributor, serving more than 4 million customers in most areas, with the exception of the City of New Westminster, where the city runs its own electrical department and portions of the West Kootenay, Okanagan, the Boundary Country and Similkameen regions, where FortisBC, a subsidiary of Fortis Inc. directly provides electric service to 213,000 customers and supplies municipally owned utilities in the same area. As a provincial Crown corporation, BC Hydro reports to the BC Ministry of Energy, Mines and Low Carbon Innovation, and is regulated by the British Columbia Utilities Commission (BCUC). Its mandate is to generate, purchase, distribute and sell electricity.

The electricity sector in Canada has played a significant role in the economic and political life of the country since the late 19th century. The sector is organized along provincial and territorial lines. In a majority of provinces, large government-owned integrated public utilities play a leading role in the generation, transmission, and distribution of electricity. Ontario and Alberta have created electricity markets in the last decade to increase investment and competition in this sector of the economy.

According to the International Hydropower Association, Canada is the fourth largest producer of hydroelectricity in the world in 2021 after the United States, Brazil, and China. In 2019, Canada produced 632.2 TWh of electricity with 60% of energy coming from Hydroelectric and Tidal Energy Sources).
Natural gas was Canada's third largest source of energy production in 2018, representing 22.3% of all energy produced from fuels in the country. By contrast, the share of fuel-based energy production from natural gas in 2013 was 17.0%, indicating a growth rate of approximately 1.06% per year.
The Waneta Dam is a concrete gravity-type hydroelectric dam on the Pend d'Oreille River in the Canadian province of British Columbia. It lies 9.5 kilometres (6 mi) downstream of Seven Mile Dam at the Pend d'Oreille's confluence with the Columbia River. It is located about 12.5 kilometres (8 mi) southeast of Trail and 0.35 kilometres (0.2 mi) north of the U.S. border at Washington.
Seven Mile Dam is a concrete gravity-type hydroelectric dam on the Pend d'Oreille River 15 km SE of Trail, 18 km downstream from Boundary Dam and 9 km upstream from Waneta Dam in the Canadian province of British Columbia. The power plant has a capacity of 848 MW and generates 3200 GWh per year. The May, June and early July flow of the river in most years, is greater than the plants capacity. During these times water is spilled, not used to generate power. The reservoir is 420 ha, which includes 170 ha of flooded river channel. Under the Canal Plant Agreement operations are coordinated with Waneta Dam.
The Kootenay Canal is a hydroelectric power station, located 19 km downstream of Nelson, British Columbia, Canada. Where the Kootenay River flows out of the reservoir formed by the Corra Linn Dam on Kootenay Lake., a canal diverts water to BC Hydro's Kootenay Canal Generating Station. Its construction was a result of the Duncan Dam and Libby Dam providing year round flows into Kootenay Lake. The powerhouse was completed in 1976.
GMR Vasavi Diesel Power Plant, owned by GMR Power Corporation Limited, was a private-owned power plant located in Basin Bridge, Chennai. It was a 200-MW LSHS fuel power plant of the GMR Group. The plant was based on two-stroke diesel engine technology from MAN B&W, Germany. It was the state's first plant commissioned by the private sector. The plant was decommissioned in 2018.
The John Hart Dam is one of three hydroelectric dams on the Campbell River, located on Vancouver Island in British Columbia, Canada. The dam is located at the outflow of John Hart Lake. The John Hart Generating Station is located nearby.
