Especially when they can foist off the costs of black swan events onto their customers, investors, insurance, and/or the government. In the mean time, they will optimize for profit in the average case.
There are certainly valid criticisms of government operated public utilities, but in places I've lived under their umbrellas there weren't any life-threatening fiascos due to under-investment in expert-recommended tail risk mitigations. Maybe the operating cost of power / water was more than elsewhere, but I didn't notice (or have the ability to shop around).
A market approach may be to let utility customers buy service with a distribution of costs including claw-backs if there is a utility failure. Such a contract may incentivize utilities to install whole-house UPSs for customers who have a "$500 per hour of downtime" service contract. One can imagine the government mandating that in exchange for the last-mile monopoly and access to customers you must offer a full range of SLAs (ranging from a griddy-like "you pay for wholesale price + vig" to "you pay more but have a fixed cost but may have service interruptions" to "you pay substantially more but get clawbacks if the utility fails to meet delivery SLAs".
Likely over the next decade we'll see a continued 3rd worldization of more public goods such that those who are wealthy can just buy a powerwall and those who aren't will freeze / boil every 8-15 years.
A less markety approach is to operate the utilities as a quasi-government (IE not-profit seeking) organization with clear goals and governance; such things have worked in the past and also failed in the past and lots of fair-weather zealots will complain that it is government overreach.
There is every reason to predict that we will continue to send the cost of failure to the government/taxpayers and send profits (plus what should be normal infrastructure upkeep) of normal operation to whoever is well enough connected to operate the utility.
Which company is going to take a hit to their profits each quarter so they can prepare properly? The companies who don't will be more competitive and successful right up until a freak event actually occurs. And if that happens, the absolute worst case is the your under prepared company goes under. Unlimited upsides and very limited downsides.
No individual company will take the profit hit without a regulation forcing all the actors to do it.
Not to make light of the events in Texas - it sounds scary and they need to be prepared for next time. But the answer isn't automatically "they should have had a gold plated the grid!". The answer might be "they should be have been prepared for a few days without power in extreme conditions".
Every new 9 gets added to 99.9...% reliability figure costs a lot more than the 9 before. At some point, it is more effective for rare events to be handled on a case-by-case basis.
The market based solution is to add a very large fine for blackouts on a per customer bases. Grid operators can still select how many actual 9’s they want, but the externalities for doing so are priced in.
Your solution will cause power prices to go up. I'm sure a lot of consumers would be happy with that trade, but why should the ones who are unhappy with it be dragged along for the ride? There is no need to force the grid to provide reliable power to people who won't pay for it.
Are you saying that the rest of the US does not have a power market with appropriate regulations? Because as far as I can tell, this crises could have been completely avoided if we didn't have our own isolated grid.

> One example of how Texas has gone it alone is its refusal to enforce a “reserve margin” of extra power available above expected demand, unlike all other power systems around North America. With no mandate, there is little incentive to invest in precautions for events, such as a Southern snowstorm, that are rare.

Give it up.
Free markets often fail to adopt low cost protections to tail events. E.g. the free market didn't get us 100% of new cars having seatbelts and airbags, government requirements did. And those standards were fought by the car manufacturers.
My point is we need regulations to mandate our energy system to be resilient to outlier events (heat/cold/flooding/high wind etc.) and that's a government function separate from the free market structure of ERCOT and actually upstream of the market ERCOT creates.
Said differently, I don't want people to critique ERCOTs market structure (a huge success) when the real issue is the government resiliency regulations in Texas (a huge failure).
