When will a battery energy storage system start in Senegal?

Construction of the battery energy storage system is expected to commence in early 2024 at the Tobène substation in Thies and is expected to become operational in 2025. Once complete, it will be one of the largest of its kind in West Africa, and will help Senegal to avoid approximately 37,000 tonnes of carbon dioxide emissions each year.

Why is battery storage important in Senegal?

Battery storage offers incredible opportunities for Senegal to reap the benefits of renewables, while ensuring people get a secure, reliable supply of energy. We are excited to begin a promising new chapter in Senegal and further strengthen our work in the renewable energy sector.”

Why do African companies choose lithium-ion technology over lead acid batteries?

These companies shift the cost of technology ownership from end-consumers to the company. These companies often can access long term credit at more competitive rates than typical African consumers or businesses. As a result, they typically opt for lithium-ion technology over lead acid batteries.

Who makes lithium ion batteries in South Africa?

China is the leading manufacturer of both lead-acid and lithium-ion batteries used in SSA. There are a few examples of lithium-ion battery assembly in South Africa, with Freedom Won, Blue Nova and Solar MD currently assembling batteries for use in local markets.

Can lithium-ion batteries be used on a rural mini grid?

The use of other battery chemistries such as lithium-ion is increasing, but this has typically been limited by a lack of local availability. Our research has suggested that most lithium-ion batteries are installed on C&I projects rather than on rural mini grids. The use of other technologies is very uncommon.

Why are batteries so expensive in Africa?

Mini grid and captive power developers often do not meet the minimum order volumes required for direct battery purchases from manufacturers. Lead-acid batteries, which are still the most used energy storage technology in Africa, are expensive to store due to the maintenance required whether they are in use or stored in a warehouse.
