But.. it's also opportunism to the max. Buy low sell high is typical stock trader/entrepreneurial mindset.
This is also an issue on multiple levels. Generation of electricity does not have to a problem per se: we just turn up our gas generators, although those are expensive to run.
Another issue is grid capacity, especially on a mid to local level when we have introduced many higher loads with heat pumps, more airconditioners, charging electric cars and induction stoves. Then we also add some reverse electricity flow with micro solar panel or wind generation, add some batteries that do whatever their owner sees fit, and we have created a far more chaotic system than just the large supplier => variable demand electricity system we used to have. Note that many electricity systems are only fused for that last scenario, not for the phantom currents that are supplied between neighbouring houses that run through the local wiring. Theoretically you could have 0A transformer current while still overloading cables.
I'm not surprised at all that a financial curtailment incentive is now introduced at more places.
