Djibouti has an installed electrical power generating capacity of 126 MW from fuel oil and diesel plants. In 2002 electrical power output was put at 232 GWh, with consumption at 216 GWh. At 2015, per capita annual electricity consumption is about 330 kilowatt-hours (kWh); moreover, about 45% of the population does not have access to electricity, and the level of unmet demand in the country's power sector is significant. Increased hydropower imports from Ethiopia, which satisfies 65% of Djibouti's demand, will play a significant role in boosting the country's renewable energy supply. The geothermal potential has generated particular interest in Japan, with 13 potential sites; they have already started the construction on one site near Lake Assal. The construction of the photovoltaic power station (solar farms) in Grand Bara will generate 50 MW capacity.
