Discovery Green has signed five new clients in the mining, property and hospitality sectors, securing long-term partnerships with Impala Platinum Holdings, KP Lime, The Capital Hotels and Apartments, Balwin Properties, and Fortress REIT Limited.
Wheeling is the delivery of energy from a generator to an end-user located in another area through the use of an existing distribution or transmission networks.
Discovery Green, part of the Discovery Group, provides affordable and price-certain renewable energy to businesses in South Africa, advancing the country’s transition to cleaner, more sustainable energy solutions.
The agreement with Implats represents a key achievement for Discovery Green’s portfolio. Beginning in 2026, a five-year Power Purchase Agreement (PPA) will provide 90% of the electricity required for Impala Refineries in Springs, Gauteng.
This agreement is expected to reduce Impala Refineries’ Scope 2 greenhouse gas emissions by more than 852,000 tonnes of CO2e over the next five years, while delivering substantial cost savings on over 130,000 MWh of electricity annually.
Patrick Morutlwa, Group COO at Implats, said: “From 2026, the PPA will reduce our Scope 2 GHG emissions by 170,484 tonnes CO2e per year and advance our goal of achieving a 30% reduction in carbon emissions by 2030, off 2019 as our baseline year.”
Discovery Green also signed a deal with KP Lime, a producer and distributor of burnt lime and dolomite. The 10-year power purchase agreement (PPA) will supply 54,000 MWh of renewable energy annually to the Bowden mine in the Northern Cape.
This agreement will replace over 90% of the mine’s energy needs with renewable energy, delivering significant cost savings and contributing to the mine’s sustainability goals.
The group said it is also finalised long-term agreements with The Capital Hotels and Apartments, Balwin Properties, and Fortress REIT Limited last quarter.
A 15-year agreement with The Capital Hotels and Apartments will supply 5,000 MWh of renewable energy annually to three of The Capital’s properties in Gauteng.
In a 20-year contract signed with Balwin Properties, Discovery Green will supply renewable energy to four Balwin sites, totalling 13,600 MWh annually.
The agreements follow a 10-year wheeling arrangement with Fortress REIT Limited, a leading property group. Discovery Green will wheel renewable energy to 14 Fortress properties, increasing Fortress’s renewable energy penetration up to 100% in these buildings.
By partnering with Discovery Green, the companies are positioned to replace more than 90% of their electricity demand with renewable energy wheeled from the largest wind and solar plants in South Africa, saving a total of 39,000 tonnes of CO2e emissions annually. The transition to renewable energy allows the companies to avoid escalating electricity costs, which are rising faster than inflation, and mitigate the impending impact of carbon taxes.
“These partnerships highlight our commitment to supporting sustainable business growth and resilience, helping companies remain competitive in an increasingly dynamic market,” said Andre Nepgen, head of Discovery Green.
