ESS Tech partners with Nigeria’s Sapele Power on 8MWh long-duration storage project

May 8, 2024

Long-duration energy storage system manufacturer ESS Tech, Inc. has partnered with Nigerian energy company Sapele Power Plc to provide an initial 1 MW / 8 MWh of long-duration energy storage.

“This agreement represents the largest battery storage system export to Africa financed by the Export-Import Bank of the United States of America to date,” a statement said.

According to the International Energy Agency, an estimated 40 per cent of all the electricity consumed in Nigeria is produced from backup generators due to an unreliable power supply.

“As we continue to grow and meet global demand for long-duration energy storage, we are proud to serve innovative use cases, demonstrating the many potential applications for ESS technology,” ESS CEO Eric Dresselhuys said. “This project demonstrates Sapele’s leadership in ensuring reliable electricity for homes and businesses with greater capital efficiency, which will be key to creating a sustainable and resilient energy system across Africa.”

Sapele board member Heather Onoh added: “This project will deliver improved reliability and efficiency for our generation assets in Nigeria. We are pleased to partner with ESS to deploy the first iron flow battery system in Africa. Long-duration energy storage will play a critical role in a resilient, reliable energy system and this is just the first of many LDES projects that we anticipate in coming years.”
