Our Generation Portfolio
Etana Energy is rapidly scaling its generation portfolio to provide South African businesses with flexible, reliable, and cost-competitive renewable energy. In a 12-month period, we successfully reached financial close on more than 500MW of renewable energy projects spanning wind, solar, and hydroelectric power.
Through these facilities, we wheel clean electricity over the national and municipal grids to help our customers achieve deep decarbonisation and long-term price certainty.
Our Projects
Technology: Run-of-river hydropower
Capacity: 5MW
Location: Ash River within the Lesotho Highlands Water Scheme near Clarens, Free State
Status: Operational
Project partners: Developed and operated by Serengeti Energy, with Growthpoint Properties holding a 30% stake.
Du Plessis Dam Solar PV2
Zen and Bergrivier Wind Farms
The Du Plessis Dam Solar PV2 project marks Etana Energy’s first solar project as an offtaker and a key milestone in scaling the company’s renewable generation portfolio.
The project reached financial close in March 2025 and will add 75MW of new renewable electricity capacity to South Africa’s grid. Construction began in April 2025 and is set to start supplying electricity to Etana’s customers through its trading platform in 2026.
Du Plessis Dam PV2 is also the first project to utilise Etana’s R1 billion payment guarantee facility, unlocked with financing from Standard Bank and Norfund. This financing structure strengthens the bankability of renewable projects and supports the development of new generation capacity for large electricity users.
Technology: Solar PV
Capacity: 75MWac (105MWdc)
Location: Near De Aar, Northern Cape
Status: In construction
Project partners: Codeveloped by Mulilo and H1 Holdings.
The Zen and Bergrivier wind farms form a cornerstone of Etana’s renewable generation portfolio and provide significant wind capacity to the trading platform.
The projects reached financial close in December 2026, with commissioning expected in mid-2027. Once operational, they will generate approximately 580GWh of renewable electricity annually under a 20-year agreement supplying Etana’s customers.
Wind generation plays a critical role in complementing solar production by delivering electricity during high-value evening and early-morning periods, improving the overall supply profile available to businesses.
The projects will displace approximately 600,000 tonnes of CO₂ emissions annually, equivalent to removing more than 225,000 cars from the road.

Boston Hydroelectric Plant
The Boston Hydroelectric Plant supplies renewable electricity to customers through Etana Energy’s trading platform. Boston Hydro became operational in October 2025, the plant generates approximately 30GWh of renewable electricity annually, providing reliable 24/7 baseload renewable power with an expected operational lifetime of more than 40 years.
Electricity from Boston Hydro is delivered through renewable electricity wheeling, allowing power generated at the plant to reach customers via South Africa’s existing grid infrastructure.
The project forms part of Etana’s renewable portfolio supplying Growthpoint Properties and its tenants through the eco₂ programme. Growthpoint has committed to purchasing 195GWh of renewable electricity annually from Etana, which is made up of Boston Hydro and the solar and wind projects that are currently in construction.
