Togo receives about four-fifths of its electricity in the form of hydroelectric power from the Akosombo (or Volta River) Dam in Ghana. The transmission line, partly financed by an interest-free loan from the Canadian government, was formally inaugurated in July 1975. There is also a hydroelectric station at Kpimé, near Kpalimé, built with Yugoslav assistance. The 65-MW Mono River hydroelectric plant, near Atakpamé, began operating in 1987. The project has an annual output of 150 million kWh, enough to meet 25% of the combined demand of Togo and the joint project's partner, Benin. A 15–20 MW hydroelectric plant has been proposed for Adjaralara, 75 km (47 mi) downstream on the Mono River. Togo's installed capacity in 2001 was 34,000 kW (approximately 90% conventional thermal and 10% hydroelectric). Electrical output that year totaled 97 million kWh, of which 97.9% was from fossil fuels and 2.1% from hydropower. Consumption of electricity in 2000 was 525.2 million kWh.
Petroleum exploration has been conducted, but no reserves have yet been located. An estimated 4,280 barrels per day of petroleum products were imported in 1994.
