In 2018, the installed capacity was approximately 105MW connected to the national grid including a seasonal 50MW from Bumbuna Hydropower plant and the rest produced from thermal plants to serve Freetown and its outskirts, but excluding power rentals from Independent Power Producers.

This innovative project combines solar energy with cutting-edge battery technology to provide stable electricity to over 500,000 residents. Think of it as a giant power bank for the West Africa's energy landscape is getting a major upgrade with the Sierra Leone Battery Energy Storage Power Station. As of 2025, this $120 million endeavor aims to store enough renewable energy to power 400,000 homes, acting as the missing puzzle piece between solar potential and actual electricity access. Sierra Leone's energy sector has been stuck in a Catch-22 situation: Here's the kicker: The country. This plant, which is expected to be completed in two to three years, will almost double Sierra Leone's total installed electricity capacity in its first phase. This reflects limited and dilapidated power infrastructure base in generation, transmission and distribution. 8% of the installed capacity, while other sources include fossil fuels, solar, and biomass. The country's energy storage power station development could: "A 50MW storage facility could prevent 18,000 tons of CO2 emissions annually - equivalent to planting 280,000.
