Of the numerous short streams that flow on Dominica, at least 30 might be sources of hydroelectric power on a small scale; about 50% of the power supply already comes from hydroelectric sources. In 1991, the Trafalgar Hydroelectric Power Station became operational, making the island nearly self-sufficient in energy. The island also has thermal power potential in the volcanic Boiling Lake, the temperature of which has been recorded in the range of 82–92° C (180–198° F ). In 2000, 67 million kWh of electricity were produced, 47.8% from fossil fuels and 52.2% from hydropower. In the same year consumption was 62.3 million kWh. Total capacity was 19 MW.
