Renewable energy trader NOA Group on Friday clinched yet another deal. Announced on Friday is that Sibanye-Stillwater and NOA have concluded a 138 MW renewable energy power purchase agreement.
This is in addition to NOA's transactions with Sereti Green, DRDGOLD, and Pan African Resources.
Headed by CEO Karel Cornelissen, NOA is a renewable energy generator, aggregator and trader and is helping to transform South Africa's energy market by enabling open-market trading.
The additional supply to Sibanye-Stillwater will increase the renewable energy portfolio of this platinum group metals and gold-mining company to 765 MW.
In terms of this agreement, Sibanye-Stillwater's South Africa operations will be supplied from NOA's portfolio of aggregated solar and wind generation facilities under a flexible ten-year agreement, supplemented by short-term supply on a take-and-pay basis.
This additional renewable energy supply to the Johannesburg Stock Exchange-listed Sibanye-Stillwater from NOA is expected to reduce the mining company's greenhouse gas emissions by 433 080 tCO₂e a year from 2028 onwards.
The electricity will be delivered through a national wheeling framework using the Eskom grid.
The transaction reflects the strength of NOA's growing fleet of renewable energy generation assets and underpins NOA's execution capability in structuring long-term renewable energy solutions for energy-intensive customers.
Cornelissen described the transaction as reinforcing the accelerating shift toward large-scale wheeled renewable energy in the mining sector.
"We have scaled to deliver 1.5 TWh per annum of renewable energy to some of South Africa's leading mining companies," Cornelissen explained in the release to Mining Weekly.
The agreement was structured to meet Sibanye-Stillwater's additional energy requirements on flexible terms, which mitigate potential variations in the group's future energy demand.
"Our role is to absorb complexity while delivering bespoke renewable energy solutions aligned to real operational objectives. This agreement demonstrates what can be achieved when scale, execution capability and long-term strategy converge," Cornelissen explained.
Sibanye-Stillwater CEO Richard Stewart highlighted the renewable energy supply agreement with NOA as "another critical step towards reducing our carbon emissions and achieving our goal of carbon neutrality by 2040".
"As we further entrench our position as the leading renewable energy user in the South African mining sector, we continue to demonstrate our commitment to creating shared value for all our stakeholders through commercially attractive, sustainable energy security, while supplying our customers with responsibly produced products," Stewart explained.
Sibanye-Stillwater has secured a 765 MW renewable energy portfolio through off-balance-sheet financing with its various projects financed by Independent power producers and other third parties. By 2028, 56% of total energy demand from the South Africa operations of Sibanye-Stillwater will be met by renewable energy supply.
The annual renewable energy cost is forecast to average 20% to 30% lower than forecast Eskom wholesale annual tariffs, translating into a saving of more than R1-billion per annum from 2028.
Through the renewable energy portfolio, greenhouse gas emissions of 2.63 million tCO₂e a year are expected to be avoided from 2028, 41% lower compared than 2024 emissions. The recent additions to Sibanye-Stillwater's SA renewable energy portfolio. The conversion factor used is 1.08 tCO2e per megawatt hour.
Sibanye-Stillwater's current portfolio of renewable energy projects comprises 89 MW of wind energy from Castle wind farm, 75 MW of solar power from Springbok solar photovoltaic, 103 MW of w...
