The project will be the first solar Independent Power Project (IPP) in Djibouti and will be located in Grand Bara, south of Djibouti City. The solar project is being fully developed by AMEA Power under a Build-Own-Operate and Transfer (BOOT) model and will generate 55 GWh of clean energy per year, enough to reach more than 66,500 people.
Djibouti's substantial potential for geothermal electricity generation, along with its rising capacity to produce energy from wind and solar power plants, should help the country reach its goals in coming years. In addition to the growing need for generation capacity, the expansion of renewable energy is key for Djibouti to diversify its economy.
Djibouti produced 654,062 MWh of electricity in 2021, according to figures from the Central Bank of Djibouti, representing a 4.3% increase relative to 2020. Improving domestic energy production will require the government to direct private investment towards electricity generation.
The sharp rise in prices of crude oil, petroleum and natural gas in the months after the start of the war have driven up Djibouti's energy import bill. To cushion the impact of price hikes on its citizens, the government suspended the automatic adjustment of fuel prices and waived taxes and levies on refined products.
The UAE-based Amea Power signed an agreement with the Ministry of Energy and Natural Resources in July 2022 to build a 30-MW solar plant. The energy produced will be sold to EDD under a power purchase agreement. Djibouti is also looking to exploit the untapped potential of wind power.
Djibouti has significant solar energy potential, with an estimated average daily global horizontal irradiance of 4.5 to 7.3 KWh per sq metre across its territory. The construction of the first large-scale solar generation project began in November 2022 in the Gran Bara Desert, which is located in the country's southern region.
