SA goes for gas, nuclear: Ramokgopa unveils big electricity shift | News24 South Africa plans to ramp up electricity generation from gas and nuclear dramatically in the next 15 years, Electricity and Energy Minister Kgosientsho Ramokgopa announced on Sunday.

This is not going to happen, but the nuclear, gas and coal lobbies will be celebrating as it stalls their otherwise imminent demise. The solar targets are far too modest given the trend elsewhere in the world and South Africa's superb solar potential

#China #nuclear power generation increased by 3.7 % but its share of total electricity output slipped for third year in a row to 4.5 %. While nuclear capacity grew by 3.5 GW, #solar capacity grew by 278 GW.

MILESTONE | This September, EU solar generation already surpassed 2024's total.

In the whole of 2024, solar generated 301 TWh of EU power. By September 2025, it reached 312 TWh.

Good morning with good news: "IRENA found that in 2024, the global average cost of electricity generated by solar PV was, on average, 41% lower than the least-cost new fossil fuel-fired power plant, as shown in the figure below."

Defects in metal tubes delay return to service of Koeberg unit 1 Defects detected in metal tubes have delayed the return to service of Koeberg nuclear power station's unit 1 until the end of August.

www.timeslive.co.za/news/south-a...
This means that the current Koeberg Unit 1 outage will be 7-month long. Unit 1 was also off line for virtually the entire 2023

The amount of down-time is scandalous, and Eskom should stop spinning this as 'proof of high safety standards'

A HISTORIC MILESTONE: For the first time, solar power generated more electricity globally than nuclear, making it the worldโ€™s 4th largest power source.

In just 5 years, solar output nearly tripledโ€”from 79 TWh (Apr 2020) to 233 TWh (Apr 2025). The energy transition is speeding up.

Important read, explaining the awful dilemma South Africa faces if it wants to keep its coal plants going

The quoted astronomical costs should be a wake-up call to those who believe "clean" coal is a viable option

Massive upscaling of renewables seems like the only reasonable solution
