en.Wedoany.com Report on Mar 31st, Chinese renewable energy technology company Sungrow has signed a major supply agreement with South African distributor Herholdt's Group to deliver commercial and industrial (C&I) battery energy storage systems (BESS) with a total capacity of 1155 MWh across South Africa.
The C&I BESS project will be implemented in phases, with deployment expected to commence in 2026. It aims to help C&I customers improve grid reliability and integrate renewable energy to address the country's persistent electricity supply constraints. The liquid-cooled systems provided by Sungrow will offer peak shaving, frequency regulation, and backup power support for applications such as factories, data centers, and logistics operations.
This agreement reflects growing demand for scalable energy storage solutions in the South African market, where frequent power outages are driving more businesses to seek independent energy supply options. Having operated in Africa for nine years, Sungrow sees this contract as a significant validation of its BESS platform specifically developed for African conditions.
As Sungrow's exclusive local partner in South Africa, Herholdt's Group will be responsible for logistics, installation, and commissioning across multiple sites. These C&I BESS utilize Sungrow's Power Conversion System technology, achieving over 95% round-trip efficiency even under heavy load conditions.
As South Africa pushes for a Just Energy Transition, such large-scale BESS deployments mark a shift away from reliance on diesel generators towards utility-scale renewables paired with storage. Sungrow stated that by the end of 2025, its global shipments of PV and energy storage equipment had exceeded 1000 GW, and it maintains a leading position as a bankable supplier in BloombergNEF rankings. The project's implementation coincides with state utility Eskom accelerating its procurement of BESS, creating complementary market opportunities for private C&I investment.
