Project Overview
The Naos-1 Hybrid Solar and Battery Project, developed by SOLA Group, is a 300 MW (435 MWp) solar PV facility with 660 MWh of battery energy storage. It is the first utility-scale solar PV and battery energy storage project in South Africa designed for wheeling to private end-users.
Financial and Operational Milestones
Enabled by long-term power purchase agreements with Sasol and Air Liquide, the project has reached Financial Close. The commercial operation date is targeted for the first half of 2028.
Technological Advancements
Naos-1's hybrid design allows it to store low-cost solar energy and dispatch it during peak demand, providing a reliable supply of clean energy at competitive tariffs. This project sets a new benchmark for utility-scale solar-plus-storage wheeling to private end-users.
Location and Development
Located near Viljoenskroon in the Free State, the project is developed, designed, and will be operated by SOLA Group. It is supported by South African institutions, including the Development Bank of Southern Africa (DBSA).
Future Prospects
Naos-1 is the first of several projects by SOLA Group, with a further 600 MW of hybrid solar and battery projects in advanced development stages. The project contributes to the modernization and decarbonization of South Africa's power system, with over 1 GW DC in operation and construction.
