I'm troubled by the amount of misleading info about the deregulated Texas electricity markets being presented here. This probably isn't the place for a lengthy discussion on this topic but I will say three things since Tesla is in the renewable energy business and their cars require electricity to work:
1) There are no fights between the electrical utility and customer in Texas over how to value the excess electricity produced by your rooftop solar because the citizens (customers) have no say in the matter and the amount they will pay you ranges from absolutely zero to very little.
2) Electricity in Texas SHOULD be cheap due to the amount of excess natural gas created by extensive fracking and the amount of cheap wind power. The natural gas prices have been hovering near zero and sometimes go negative.
But electricity in Texas is not as cheap as it would be under a regulated system. The energy companies are making record profits. There are 15 states with cheaper residential electricity than Texas and almost all of them are fully regulated in a traditional manner. This, despite the fact that power in Texas should be cheaper, not due to de-regulation but due to abundant and cheap natural gas. Texas is sorely lacking in natural gas pipelines to export the huge volume that is a by-product of fracking so gas prices are the cheapest in the nation. It literally has nowhere to go. But the electrical consumer is not benefitting from this in the form of cheap electricity.

3) Texas deregulated electricity in 1999 and by 2012 Texas was ranked the lowest in the nation for grid reliability. Do I need to say how important it is to have reliable electricity?

As TSLA investors we should all be experts in misinformation and propaganda by now. Energy companies in Texas put out a lot of propaganda with regard to how great deregulation is. They wouldn't do this if it didn't allow them to take a bigger slice of the pie home. Regulated utilities are incentivized to have reliable power while in a completely deregulated system the only incentive is to sell more electricity. It may not pay to invest in the #1 most important thing, reliability.
