“André de Ruyter says Eskom is unfixable” In South Africa those who argued passionately that ⁦Eskom Hld SOC Ltd⁩ is unfixable, will be the same “experts” that will educate all why load shedding has stopped. mybroadband.co.za/news/energy/53…

South Africa never had a shortage of installed generation capacity. The intention to phase-out coal couldn’t exist simultaneously with the intention to improve its performance. There is now a clear focus on improving performance

It pretty obvious now, that framing ‘inadequate transmission’ as the ‘biggest constraint’ to end loadshedding was another fairytale. Improved EAF solved load-shedding Building transmission lines to connect variable generation adds very little to System Adequacy. Long term

The biggest risk to Security of Supply (Unserved Energy) in RSA, is the timing of the retirement of coal plants in relation to their replacement by CCGT gas capacity, not Transmission & VRE - Medium Term System Adequacy Outlook 2025

Every power system irrespective of the amount of variable energy (solar & wind), have enough dispatchable capacity to supply the total peak demand. For Energy Security, every system should have sufficient dispatchable capacity to supply max demand even if variable energy is at

“60GW of wind installed, only 0.3GW showed up” Jim Robb, NERC As a mandatory rule, renewables require backup from dispatchable capacity for grid reliability. But unreliable dispatchable generation cannot be ‘fixed’ by renewables.

There is no Power System Operator in the world who will prescribe the installation of Variable Weather Dependent Generation to solve reliability problems of Dispatchable/Baseload Capacity In fact, it’s almost mandatory that high penetration of Variable Generation must be backed

When Germany made a political decision to phase-out nuclear power in 2011, the plan was to replace it with solar and wind. After installing ~200GW of solar & wind they have discovered painfully that it was a ‘ huge strategic mistake’ . Now Germany is planning more fossil gas
