Surprise, surprise.
The Enron crowd came out and made a complete mess of a well enough functioning system in California with their deregulation sparkle ponies 20 years ago. As the problem was growing but before it completely blew up, I started monitoring the state's ISO website which showed all daily statewide power supply and demand graphs and power plants taken down for maintenance, etc. It was obvious to me that during a non-energy intensive portion of the late fall and winter that they were taking down an excessive number of plants so they could sell power at a ridiculous marginal cost by taking down just enough plants at their discretion to cause shortages. Months later, investigators confirmed that this was part of what they were doing. Crooks. While the Texas situation is different, it seems to involve some players and government officials with the same attitudes. I simply do not trust these swindlers.
It took us a long time to recover from that fiasco, and has done long term damage to energy provision here from which we're still recovering. Deferred maintenance that has added to our recent fire issues was partly a result of recovering from this, plus greedy energy company execs here looking for high pay and shareholder dividends instead of necessary maintenance, and compliant PUC boards who seem to have bent over backwards for them since then. Boring, reliable, and cost-plus under regulated monopolies is my preference for energy, while eventually working towards a future of more distributed renewables tying into the grids. Currently, some of the older generating plants here are being converted into massive battery storage units and are using the existing and modified distribution infrastructure at the plants, repurposed to accommodate more distributed and renewable sources coming from wind and solar farms and also more rooftop solar. It's still an experiment in progress while we continue with more traditional sources and determine how to best transition over time. We're planning on adding solar panels with our next roof replacement.
