South Africa to procure 9.6GW of new capacity: 4.6GW batteries, 5GW gas

Energy minister Kgosientsho Ramokgopa announced a determination for 9.6GW of new capacity — 4.6GW of battery storage and 5GW of gas-to-power, with no new wind or solar. The move addresses a daytime surplus of over 4GW and rising curtailment payments; battery investment is estimated at upwards of R90-billion.

• 4.6GW of batteries and 5GW of gas-to-power, 9.6GW total
• Grid surplus averages more than 4GW, mostly during the day
• Battery investment estimated at upwards of R90-billion
• Batteries will charge from curtailed power and discharge at evening peak
