Terra Firma’s R1.3 Billion Solar Project to Cut South Africa’s Rising Electricity Costs

Terra Firma, a leading South African renewable energy company, has unveiled plans for a groundbreaking R1.3 billion ($73.8 million) solar energy project, designed to help alleviate the financial strain of escalating electricity costs in South Africa. As the country faces a mounting electricity crisis and the potential for Eskom’s tariffs to rise by as much as 43.55% by mid-2025, Terra Firma’s solar project is poised to offer substantial relief to businesses through sustainable and cost-effective energy solutions.

110MWp of Solar Energy to Power Key Industries

The initiative, which will deliver 110MWp of solar power, is targeted at South Africa’s commercial and industrial sectors, including manufacturing, extractive industries, and digital infrastructure. The project will be implemented across two major sites in Gauteng — Hammanskraal (87MWp) and Rietfontein (23MWp) — and will leverage Eskom’s grid through a financial model known as energy wheeling.

What is Energy Wheeling?

Energy wheeling allows Terra Firma to transport renewable energy generated at its solar sites to customers located elsewhere, using Eskom’s distribution network. This model provides businesses with a reliable and flexible off-site renewable energy solution, helping them cut their electricity costs significantly. Terra Firma’s CEO, Grant Berndsen, explains that this model has the potential to save customers up to 40% on electricity bills.

Addressing South Africa’s Energy Crisis

With Eskom’s tariffs set to increase, Terra Firma’s solar project is particularly timely. Many businesses and municipalities are struggling to keep up with rising electricity prices, and renewable energy offers a more affordable and environmentally friendly alternative. Terra Firma’s Power Purchase Agreements (PPAs), ranging from five to 20 years, provide customers with long-term energy cost stability while contributing to South Africa’s transition toward a low-carbon economy.

Advanced Technology and Sustainability

The project will incorporate smart metering systems at both the generation sites and customer locations. Terra Firma’s proprietary software will track energy consumption, reconcile it against utility tariffs, and ensure maximum cost savings for its customers. By combining solar energy with battery energy storage and other embedded generation systems, businesses can further optimize their energy strategies, ensuring they maintain a stable supply of renewable energy during daytime operations.

This landmark solar project is expected to play a crucial role in reducing South Africa’s reliance on coal-powered electricity, while promoting sustainability and cost-efficiency across various sectors of the economy.
