The economy of Papua New Guinea (PNG) is largely underdeveloped with the vast majority of the population living below the poverty line. However, according to the Asian Development Bank its GDP is expected to grow 3.4% in 2022 and 4.6% in 2023. It is dominated by the agricultural, forestry, and fishing sector and the minerals and energy extraction sector. The agricultural, forestry, and fishing sector accounts for most of the labour force of PNG while the minerals and energy extraction sector, including gold, copper, oil and natural gas is responsible for most of the export earnings.
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant.
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.
Hydro-Québec is a Canadian public utility Crown corporation based in Montreal, Quebec. It manages the generation, transmission and distribution of electricity in Quebec, as well as the export of power to portions of the Northeast United States.

Ontario Hydro, established in 1906 as the Hydro-Electric Power Commission of Ontario, was a publicly owned electricity utility in the Province of Ontario. It was formed to build transmission lines to supply municipal utilities with electricity generated by private companies already operating at Niagara Falls, and soon developed its own generation resources by buying private generation stations and becoming a major designer and builder of new stations. As most of the readily developed hydroelectric sites became exploited, the corporation expanded into building coal-fired generation and then nuclear-powered facilities. Renamed as "Ontario Hydro" in 1974, by the 1990s it had become one of the largest, fully integrated electricity corporations in North America.

As of 2018, hydroelectric power stations in the United Kingdom accounted for 1.87 GW of installed electrical generating capacity, being 2.2% of the UK's total generating capacity and 4.2% of UK's renewable energy generating capacity. This includes four conventional hydroelectric power stations and run-of-river schemes for which annual electricity production is approximately 5,000 GWh, being about 1.3% of the UK's total electricity production. There are also four pumped-storage hydroelectric power stations providing a further 2.8 GW of installed electrical generating capacity, and contributing up to 4,075 GWh of peak demand electricity annually.
