February 20, 2023 — A major Texas energy trade association says it can work with a new electricity market system favored by the Public Utility Commission of Texas (PUC) called the Performance Credit Mechanism (PCM).
Speaking to the Texas Legislature’s Business and Commerce committee on Thursday, Executive Director of Texas Competitive Power Advocates (TCPA) Michelle Richmond said the organization representing wholesale power marketers and generators would be able to build the needed 4500 MW of new natural gas generation under the PCM.
The TCPA represents a majority of providers in the ERCOT grid, largely natural gas but also including coal and nuclear energy.
The PUC has said the PCM is intended to incentivize the production of power during peak demand hours in extreme weather when solar and wind or thermal power equipment production fails, such as occurred in Texas in February, 2021.
Ms. Richmond followed testimony from former PUC member Rebecca “Becky” Klein, who gave some historical perspective to changes in the Texas electricity markets over the past 30 years.
Ms. Klein expressed some skepticism about the PCM plan, noting that it presents a realignment of risk factors, saying she needed to study the plan further.
Ms. Richmond then provided views of the state power markets from the power providers’ perspective, saying the TCPA agrees with the PUC that the new plan would see to it that required grid reliability would be met.
“Today, the ERCOT market is a volatile market,” she said, but the PCM “removes the scarcity” therein, indicating that there is some enthusiasm for the new plan among the TCPA members.
There is about 4500 MW of power generation ready to be built, some of it in response to the announcement of the PCM, Ms. Richmond said.
The markets need to get away from scarcity power generation mechanisms, as are found today, and move toward more market stability, which the PCM provides, she added….
