After reforms, the South African electricity market has gradually overcome the persistent power rationing dilemma. Industrial enterprises are no longer solely pursuing basic power supply; stable and adjustable green electricity has become a rigid demand. Envision Energy, in collaboration with the local SOLA Group and WBHO, has finalized a cooperation agreement for the supply of 660 MWh of energy storage, implementing the Arctic Express No. 1 Solar-Storage Project. This project is a large-scale private new energy initiative in South Africa that has completed financing, with a supporting 300 MW photovoltaic capacity and a total energy storage capacity of 855 MWh. It specifically serves leading chemical enterprises and is scheduled to commence operations in the first half of 2028. This collaboration transcends the mere sale of equipment, offering a 25-year long-term operation and maintenance service. It also points out a new direction for domestic energy storage enterprises to explore the African market.  

Basic overview of the project

The Arctic Express No. 1 is located in the vicinity of Viljoenskloon in the Free State province of South Africa. It boasts a photovoltaic (PV) AC side capacity of 300 MW and a peak installed capacity of 435 MW. The 660 MWh energy storage system provided by Envision is exclusively for Sasol and Air Liquide. These two major industrial enterprises have signed long-term power purchase agreements, with electricity being transmitted through the national power grid. The project is expected to complete financing and commence construction in February 2026. It relies on energy storage to regulate PV power generation during the day, fill the gap in industrial electricity consumption at night, and accommodate the uninterrupted production needs of the chemical industry.

Market demand shifts

The new regulations for electricity regulation in South Africa will be implemented in early 2025, opening up market-oriented electricity purchasing channels. The local power grid has maintained stable power supply for 385 consecutive days. Even though there is no longer large-scale power rationing, industrial customers have long been targeting private photovoltaic (PV) and energy storage projects. Their core demands focus on controllable electricity usage periods, stable electricity prices, and meeting carbon emission standards. The dispatchable characteristics of energy storage complement the shortcomings of PV power generation, becoming a core supporting facility for industrial carbon reduction and stable production, and spurring the implementation of large-scale energy storage.

New logic of competition in overseas markets

The threshold for the energy storage industry in South Africa continues to rise, and purely low-priced equipment no longer holds competitiveness. Financing feasibility, long-term operation and maintenance capabilities, and local collaboration abilities have become core conditions for signing contracts. Envision provides a comprehensive solution encompassing integrated design, manufacturing, and operation and maintenance, which aligns with the new standards of the local market. Domestic energy storage enterprises can enter the market through two paths: one is to possess system integration and long-term operation and maintenance capabilities and jointly bid with local enterprises; the other is to provide energy carbon management services for mining and chemical parks. The upcoming 600MW hybrid project to be developed by SOLA Group will become a replication model for the industry.Editor/Min Jing
