- 28 GWh of renewable electricity to be supplied annually from 2028.
- Estimated emissions reduction of 25,000 tCO2e per year.
- Diversified wind and solar portfolio exceeds 700 MW capacity.
Afrox, a leading industrial gases and welding products company in sub Saharan Africa, has signed a 10 year power purchase agreement with Discovery Green to supply renewable energy to its Kuilsriver air separation unit in Cape Town, South Africa.
Under the agreement, Discovery Green will deliver about 28 GWh of renewable electricity each year starting in April 2028. The supply will be sourced from a diversified portfolio of wind and solar projects located across the Western Cape, Mpumalanga and the Free State.
The clean energy supply is expected to reduce Afrox’s operational carbon emissions by around 25,000 tCO2e annually, supporting the company’s decarbonisation strategy and transition toward lower carbon operations.
Ferdinand Kuehner, Managing Director of Afrox, said the agreement reflects the company’s commitment to increasing renewable energy sourcing and reducing Scope 2 emissions. He added that the deal strengthens electricity supply resilience in South Africa and supports continued delivery of essential industrial gases with a reduced carbon footprint.
The renewable energy will be sourced from a portfolio that includes the Overberg Wind Farm, as well as the Tournee Solar Farm and Notsi Solar Farm. The combined portfolio currently exceeds 700 MW of generation capacity and is expected to expand as Discovery Green grows its asset base.
Discovery Green’s aggregation model combines wind and solar resources across multiple geographic locations to ensure a stable and consistent renewable energy supply. This approach enables alignment with Afrox’s industrial load profile while delivering operational reliability and long term price certainty.
Andre Nepgen, Chief Executive of Discovery Green, said the agreement demonstrates how industrial companies can modernise energy procurement. He noted that the company provides a platform that simplifies the structuring of complex renewable portfolios, enabling long term solutions that deliver both price certainty and sustainability.
