Renewable-energy solutions provider Scatec is optimistic that its R16.4-billion solar-battery project in the Northern Cape will finally address long-standing questions about the so-called “intermittency” of renewables. The project, which achieved financial close this week, will couple 540 MW of solar photovoltaic (PV) generators to lithium-ion batteries with a capacity of 225 MW/1 140MWh to provide 150 MW of dispatchable power into South Africa’s grid under a 20-year power purchase agreement.
