Texas deregulated its electricity market 10 years ago. Greentech Media calls it the “oldest and most successful deregulated electricity marketplace in the U.S.” It’s certainly the oldest, but is it really the most successful?

The Greentech Media article trots out rosy statistics, such as the increase in renewable energy, which increased from one percent in 2002 to over 8.5 percent last year. Wind grew 10 times over, from 2.6 million megawatt hours (mWh) to 26 million mWh. Texas has over 10,000 megawatts (MW) of installed wind capacity, more than all other states. I am all for increasing renewable energy, and Texas should be proud that it leads the U.S. in installed wind capacity.

The article also cites the fact that by 2008, 80 percent of registered Texas voters “favored a competitive electricity market, and by 2010, 55 percent of residential customers had selected a competitive retail electricity provider or product.” Okay, Texas voters favor a competitive electricity market, but does that mean deregulation has brought lower electricity prices?
