South African electricity trading platform Etana Energy has signed a 10-year power purchase agreement with mining group Sibanye-Stillwater, a leading producer of gold and platinum group metals, according to an announcement on Friday, February 6, by indirect shareholder Chariot Limited.
Under the agreement, Etana will supply up to 220 MW of renewable electricity to Sibanye-Stillwater’s mining operations from late 2027.
The power will be generated from Etana’s portfolio of wind and solar projects and delivered to the mining sites through wheeling arrangements on South Africa’s national electricity grid, Ecofin Agency reported.
The contract is designed to cover Sibanye-Stillwater’s current and future electricity needs, while helping to reduce power costs and cut carbon emissions.
“This is another material offtake agreement signed with a major industrial customer which continues to underline the scale of the market that Etana can address,” said Benoit Garrivier, chief executive of Chariot’s renewable power division.

The agreement further strengthens Etana’s presence in South Africa’s private power contract market. In December 2025, Chariot reached financial close on two wind projects in the Western Cape with a combined capacity of 190 MW, with all output contracted to Etana under 20-year agreements.
In March 2025, Etana also signed a 20-year deal covering the entire output of the 105 MWp Du Plessis Dam PV2 solar project in the Northern Cape.
That power will be resold to industrial customers, including Sibanye-Stillwater and Tharisa.
The rise in such agreements highlights the growing use of wheeling and private power purchase contracts in South Africa, as the electricity market gradually opens to private operators and large industrial users seek more reliable and cleaner energy sources.
