How much of Texas should one electric company power? As much as the free market dictates, a North Texas lawmaker says.

Texasย prohibits companies from owning or controlling more than 20 percent of the generation capacity on the electric grid. The ban was a key piece of the law that deregulated the state’s electricity market in 1999. But state Rep.ย Matt Krause, R-Fort Worth,ย filed legislationย this week that would eliminate that cap, worrying consumer advocates who say the change would open the door to market abuse and higher electric rates.

ACBS animated gifโ€œWe still think the market can take care of itself and should take care of itself,โ€ said Clayton Knippa, Krauseโ€™s chief of staff. โ€œThe arbitrary 20 percent maybe isnโ€™t as necessary as it was when it was first conceived of.โ€

The Texas Public Policy Foundation, a conservative think tank, supports the change. โ€œThe state of Texas just shouldnโ€™t have anything to do with mandating or regulating installed capacity,โ€ said Bill Peacock, the groupโ€™s director of research.

But consumer groups say the proposal would eliminate a fundamental consumer protection โ€“ one that keeps the electricity market competitive by preventing behemoths from controlling large swaths of it.

โ€œWhat this basically means is that the more powerful companies end up controlling prices, and it would be bad for consumers,โ€ said Tom โ€œSmittyโ€ Smith, director of the Texas office of Public Citizen, a nonprofit advocacy group.

Public Utility Commissioner Ken Anderson Jr. said that the 20 percent threshold wasn’t sacred but that officials created it to ensure โ€œrobust competition in the wholesale market and to keep from a monopoly situation from occurring โ€“ or a duopoly.โ€

Knippa said that the rule had outlived its purpose and that Texas has other ways to ensure mammoth power companies donโ€™t toy with the market.

Other state laws, for instance, bar generators from abusing their market power.

โ€œMarket power,โ€ according to a 2006 Public Utility Commission rule, is โ€œthe ability to control prices or exclude competitionโ€ in a market. The rule defines โ€œabuseโ€ of such power as practices that are โ€œunreasonably discriminatory or tend to unreasonably restrict, impair or reduce the level of competition.โ€ Examples of such practices include predatory pricing, withholding of production, precluding entry and collusion.

Charges of such market power abuse are not unheard of.ย In 2005, for example,ย state investigators accusedย TXU Corp. (now called Luminant) of controlling such a large share of the power-generation market that it drove up wholesale electricity prices.ย Despite a recommended fine of $210 million, Luminantย ended up paying $15 million as part of a settlement in which it denied wrongdoing.

Luminantโ€™s power plant fleet can typically power about 20 percent of the stateโ€™s grid. The company is a subsidiary of Energy Future Holdings, which has been entangled in bankruptcy proceedings since last April. Krauseโ€™s bill could make it easier for other large generators โ€“ such as Calpine or NRG Energy โ€“ to buy Luminantโ€™s plants.

Krause wasnโ€™t motivated by those implications, Knippa said.

Krauseโ€™s bill would also prohibit the utility commission from switching Texas from an โ€œenergy onlyโ€ market to a โ€œcapacity market,โ€ whichย would pay power plants to maintain excess capacity. That issue spurred heated debate throughout much of 2013, but simmered after the commissioners backed off the discussion. Consumer groups side with Krause on that issue.ย (Read moreย about the capacity market debate.)

“We would certainly agree that the capacity market is the wrong way to go,” said Jake Dyer, a policy analyst with theย Texas Coalition for Affordable Power. But nixing the 20 percent ownership rule? That would eliminate a “key consumer protection,” he said.
