Who's No. 1 in Texas electricity?

According to J.D. Power and Associates it’s Houston-based StarTex Power.
The second annual survey of the state’s competivie electric retail markets by the consumer survey firm asked consumers to rate their providers based on 1. pricing; 2. billing and payment; 3. communications; and 4. customer service.
StarTex Power scored 714 on a 1,000-point scale and did particularly well on the price factor. Green Mountain Energy (last year’s No. 1 company) was second with a 694, with good billing and payment; communications and customer service scores. Amigo Energy was third with 681.
Overall satisfaction among residential electric customers in Texas “decreased notably” in 2009 J.D. Powers notes, down 9 points on a 1,000-point scale to 629. This was largely due to decreased satisfaction with pricing, which averages 601 in 2009, down from 614 in 2008.

“Residential retail customers have experienced wide fluctuations in their electricity rates during the past year due to volatility in natural gas prices and other costs associated with power generation,” said Jeff Conklin, senior director of the energy and utility practice at J.D. Power and Associates. “For this reason, customers on fixed-price programs are considerably more satisfied than customers on variable programs–by a difference of nearly 100 points.”

“Wide fluctuations” is putting it mildly considering what happened last summer.
