This is not a criticism, though I am curious. I'm interested in why you chose to delete the paragraph about the TCAP study, namely:

According to a 2014 report by the Texas Coalition for Affordable Power (TCAP), "deregulation cost Texans about $22 billion from 2002 to 2012. And residents in the deregulated market pay prices that are considerably higher than those who live in parts of the state that are still regulated. For example, TCAP found that the average consumer living in one of the areas that opted out of deregulation, such as Austin and San Antonio, paid $288 less in 2012 than consumers in the deregulated areas." However, the report concluded that re-regulating the market would not solve the issue. TCAP instead offered a series of reforms designed to increase market efficiency.

I think that the first two sentences make a valuable addition to the article, though the last sentence likely violates NPOV. Perhaps the information would be better moved to a different section of the article dealing with effects of deregulation.

I have made a small edit to the article in the past, though I don't remember what it was. I have been following this issues since the late 90s. A.T.S. in Texas (talk) 21:31, 11 January 2023 (UTC)
