CAPE TOWN, South Africa, June 25, 2026 /PRNewswire/ — Envision Energy, a global 
leader in green technology, has signed an 660MWh battery energy storage system (
BESS) supply agreement with the SOLA Group and WBHO for the landmark Naos-1 project.
As the largest privately contracted hybrid renewable energy initiative to reach 
financial close in South Africa, Naos-1 highlights the country’s shift toward more
flexible, market-driven, and low-carbon power systems. The agreement also marks 
a key milestone in Envision Energy’s expansion in Africa, reinforcing its commitment
to advancing the region’s energy transition through integrated renewable solutions.

Located near Viljoenskroon in South Africa’s Free State, Naos-1 combines 300MW of
solar PV generation with 660MWh of battery storage to deliver reliable, dispatchable
renewable power to major private businesses. Designed for wheeling across the national
grid, the project enables clean electricity generated in one location to be supplied
to offtakers across the country. By integrating solar with storage, Naos-1 addresses
renewable intermittency challenges and enhances grid stability.

Leveraging its vertically integrated BESS expertise across the full value chain,
Envision Energy will provide comprehensive technical support for the project, spanning
the design, manufacturing, operation and maintenance of the energy storage system.
Backed by advanced battery technology and AI energy system, Envision’s solution 
will enable intelligent optimization and ensure safe, efficient and reliable performance
over the project lifecycle. A 25-year Long-Term Service Agreement(LTSA) between 
Envision and SOLA Group will further support the project’s ongoing operation and
maintenance, contributing to the continued development of South Africa’s renewable
energy ecosystem.

John Lee, General Manager of Asia & Africa Markets at Envision Energy, said: "Naos-
1 demonstrates how integrated renewable and storage solutions can redefine the future
energy systems, delivering not only clean power, but also reliability, flexibility,
and economic value at scale. Envision is proud to support this landmark project 
and to work alongside leading partners to accelerate the transition toward a more
sustainable energy future in South Africa and across emerging markets."

"Across South Africa and beyond, businesses are seeking energy solutions that balance
sustainability, reliability, and cost-effectiveness," said Ian Burger, Managing 
Director of SOLA Build at SOLA Group. "Naos-1 reflects a new generation of energy
infrastructure, one that is flexible, scalable, and aligned with the needs of modern
power markets. Through collaboration with strong technology partners like Envision
Energy, we are helping to unlock new pathways for private-sector participation and
advancing the development of a more resilient and future-ready energy system."
