Another day, another retail electricity provider bites the dust.
Company representatives didn't return phone calls.
Three other electricity retailers have stopped serving customers in as many weeks, unable to make ends meet as wholesale power prices spike.
Sure Electric, a Houston retailer, said in Thursday's motion that it serves around 6,500 retail customers. When wholesale power prices began to spike last month to thousands of dollars per megawatt-hour, almost 5,000 of Sure Electric's retail contracts became unprofitable.
Sure Electric said in the filing that it entered bankruptcy to avoid defaulting on a security deposit demanded by the grid operator, the Electric Reliability Council of Texas.
When wholesale prices rise, ERCOT requires smaller retailers who don't have certain debt ratings to post higher security deposits.
A third company, National Power, couldn't honor its fixed-rate contracts and allowed ERCOT to switch its customers to default providers.
Larry Kelly, chief operating officer for retailer Texas Power LP, said, "These spikes, they're going to kill us.
"They're going to kill the consumer."
He said his company isn't in financial trouble, but if wholesale prices remain high, he will have to find a way to shed customers in Houston or South Texas, where he can't make money.
Mr. Kelly fired off an e-mail to the Public Utility Commission and its staff on Thursday, complaining about ERCOT's credit requirements and the way the market awards every power generator the highest bid for power at any given time.
Power generators bid their electricity to ERCOT each day, asking for certain prices for their power. ERCOT accepts the lowest bids first, then moves to the higher bids as demand for power increases in the course of the day.
The highest bid sets the price for power for the entire market.
"There's nothing to stop generators from bidding $1,000 every day," Mr. Kelly said.
An alternate method would be to award each power generator only the price it bid, even if other power from other generators fetches higher prices.
Dan Jones, the PUC's independent market monitor, said congestion on lines that carry power to Houston and South Texas caused the high prices, which reached thousands of dollars per megawatt hour at some points during the past few weeks.
He said he's monitoring the situation for evidence of manipulation, but he has yet to issue notices of violation to any companies.
The ERCOT board will hold an emergency meeting Friday to discuss new methods to relieve the power line congestion.
