NOA set to deliver 1.5TWH of renewable energy to mining sector per year
NOA has secured a 401GWh per annum renewable energy supply agreement with Sibanye-Stillwater (JSE: SSW; NYSE: SBSW), positioning the energy trader to deliver approximately 1.5TWh of renewable energy to the mining sector annually.
The transaction represents one of NOA’s largest agreements to date, reflecting the strength of its commercial offering and execution capability in structuring complex, long-term renewable energy solutions for energy-intensive customers. The energy supply agreement follows NOA’s acquisition of the Stellar solar PV project from DRDGOLD, which now forms part of NOA’s generation portfolio.
“This transaction reinforces the accelerating shift toward large-scale wheeled renewable energy in mining,” said Karel Cornelissen, CEO of NOA Group. “We have scaled to deliver approximately 1,5TWh p.a. of renewable energy to some of South Africa’s leading mining companies.”
The additional contracted capacity increases Sibanye-Stillwater’s renewable energy portfolio to approximately 765MW, reinforcing its position as the largest contracted private renewable energy consumer in the South African mining industry and a leader in the country’s private sector transition to renewable energy.
This offtake agreement represents a further step in scaling private renewable energy procurement within South Africa’s mining sector.
Taking Sibanye’s unique operational and consumption requirements into account, NOA designed a bespoke solution that combines long-term and short-term supply arrangements to ensure optimal alignment with Sibanye’s energy objectives. The offtake arrangement is underpinned by a long-term energy supply agreement, providing approximately 401GWh per annum through fixed allocations. This is supplemented by a 100GWh per annum short-term flexible agreement, enabling further cost savings for Sibanye. Electricity will be supplied from NOA’s diversified fleet of generation facilities, enabling supply resilience across operations.
Sibanye-Stillwater CEO, Richard Stewart, commented, “We welcome this renewable energy supply agreement with NOA, which is 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 SA 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.”
Cornelissen added that Sibanye-Stillwater ranks among the country’s top ten energy users by contracted capacity, with NOA further supporting Sibanye’s decarbonisation drive. “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.”
Beyond the initial supply, the agreement provides a platform for expanded energy solutions. A proposed second phase aims to incorporate battery energy storage systems (BESS) and additional renewable energy volumes, creating opportunities for further cost efficiencies and enhanced supply security over the long term.
