The Public Utility Commission voted Thursday to make a substantial change to the state’s electricity market in a controversial effort to get the whole system to be more reliable. The agency said it will let the Legislature review its plan before moving forward with putting it in place.
The idea, known as the “performance credit mechanism,” is a first-of-its-kind proposal. It’s meant to help produce enough power when extreme heat or cold drives up demand and electricity production drops for various reasons — such as a lack of sun or wind to produce renewable energy or equipment breakdowns at gas- or coal-fired power plants.
Under the new concept, which still has many details to work out, companies such as NRG would commit to being available to produce more energy during those tight times. The companies would sell credits to electricity retailers such as Gexa Energy, municipal utilities and co-ops that sell power to homes and businesses.
The credits are designed to give power generators an added income stream and make building new power plants worthwhile.
Theoretically, the credits help retailers and customers by smoothing out volatile price spikes when demand is high — but there’s wide disagreement over whether this will happen in practice. Some electricity providers filed for bankruptcy after the 2021 winter storm because they had to pay so much for power.
Critics of the plan say the idea is risky because it wasn’t properly analyzed and has never been tested in another place. Members of the Senate Committee on Business and Commerce wrote to the PUC in December that they had “significant concern” about whether the proposal would work.
Experts disagree on whether the performance credits will actually convince power companies to build more natural gas plants, which are dirtier than wind and solar energy but can be turned on at any time. Some say new plants will be built anyway. Others say companies can simply use the credits to make more money from their existing plants without building more.
Michele Richmond, executive director of Texas Competitive Power Advocates, wrote in her comments to the commission that the group’s members were “ready to bring more than 4,500 [megawatts] of additional generation” to the state grid if the new system were adopted. That would be enough to power 900,000 homes. The group’s members include Calpine, Luminant and NRG.
If the PUC doesn’t change the market, there won’t be enough reason to invest in building new power generation facilities and keep operating existing facilities, she wrote.
The Lone Star Chapter of the Sierra Club was among groups that asked the PUC to spend more time considering whether the new credits are the best solution “before making fundamental changes to our market that would increase costs to consumers,” as Conservation Director Cyrus Reed wrote.
The independent market monitor, Potomac Economics, which is paid by the PUC to watch the market for manipulation and look for potential improvements, does not support the idea. The group believes enough corrections have been made already to make sure the grid is reliable.
Still others, such as Alison Silverstein, a former senior adviser at the PUC and the Texas Public Power Association, which is made up of municipal-owned utilities, cautioned that there wasn’t enough reliable information and analysis about the proposed credits to make such a significant decision.
The grid’s reliability must improve, Silverstein wrote to the PUC, but “we cannot do so at any cost, and we cannot do so using poorly understood, poorly-analyzed, or unproven market mechanisms to address unclear problem definitions and goals.”
Silverstein added: “If the commission makes a bad decision on … market reform due to haste, erroneous problem definition, sloppy analysis or misguided rationalizations, all Texans will bear the consequences for years through higher electric costs, lower reliability, and a slower economy, and millions of lower income Texans will suffer degraded health and comfort as they sacrifice to pay their electric bills.”
See here for some background. The PUC unanimously approved the plan, which was spearheaded by Greg Abbott’s appointed Chair. I sure don’t know enough to say whether this will work or not. It sounds like it could, but there’s more than enough uncertainty to make it a risky proposition. I get the argument against waiting for more data, but I have to wonder if there were some other ideas with greater certainty that could have been used in the meantime. Not much to do but hope for the best now, and maybe take the idea of “accountability” more seriously in the next election. The Chron, whose headline says that electricity prices are likely to rise under this plan, has more.
