Belle Rive Farm in South Africa is taking a major step toward energy independence by developing what is expected to be the country’s largest solar and battery energy storage system for an agricultural operation. Located in the Free State province, the commercial farm has appointed renewable energy company RenEnergy to design and build the project, which will allow the farm to operate completely off the national electricity grid.
The project will include a 4.89 MWp ground-mounted solar photovoltaic (PV) system combined with a 20 MWh battery energy storage system (BESS). Once completed, the installation will provide reliable electricity across more than 2,000 hectares of farmland through a 17-kilometre medium-voltage distribution network. The system is designed to deliver uninterrupted power for the farm’s daily operations while reducing dependence on conventional electricity sources.
The decision to invest in renewable energy has been driven mainly by rising electricity prices in South Africa. Power tariffs from the national utility Eskom have increased significantly in recent years, including a 12.74% increase in 2025 and a further 8.76% hike from April 2026. With electricity accounting for around 6% of total farming input costs, and an even larger share for farms that rely heavily on refrigeration, securing a stable and cost-effective energy supply has become increasingly important.
Belle Rive Farm grows several important crops, including seed potatoes, ware potatoes, pecan nuts, onions, and maize. These farming activities require continuous electricity for irrigation systems, crop processing, and cold storage facilities that preserve produce after harvest. Any interruption in power can affect productivity and product quality.
To meet these operational requirements, RenEnergy carried out a detailed assessment of the farm’s electricity consumption by analysing half-hourly power demand across multiple supply points. Based on this analysis, the company designed a battery storage system capable of supplying critical loads during the night and extended periods of low solar generation. The battery will also eliminate the need for diesel generators and reduce dependence on backup grid power.
Industry estimates suggest that the Belle Rive project will be one of the largest behind-the-meter battery storage installations in Southern Africa. Most similar commercial, industrial, and agricultural projects in the region currently range between 10 MWh and 20 MWh. The farm’s 20 MWh battery alone is expected to represent around 5% of South Africa’s projected annual commercial, industrial, and agricultural battery storage installations. The project highlights the growing role of solar and battery storage in improving energy security while helping agricultural businesses manage rising electricity costs.
