Renewables are growing on the Texas power grid. Republicans want more natural gasoline.


Clear vitality is quickly rising on the Texas power grid, however regulators in the Lone Star State are now contemplating a plan that might give fossil fuels a lift.
The zero greenhouse gasoline emissions trio — wind, photo voltaic, and nuclear vitality — offered more than 40 % of electrical energy in the state in 2022. It was a yr when a number of Texas cities skilled their hottest summers on file, driving electrical energy demand to its highest ranges ever as followers and air conditioners switched on. Winter proved irritating too, with freezing temperatures final month pushing winter electrical energy peaks to record-high ranges, narrowly avoiding outages.
Texas wasn’t alone. Over the previous yr, states like California have confronted their very own brushes with blackouts as searing temperatures drove up electrical energy consumption whereas the ongoing drought in the Western US throttled power provides. All through the nation, renewable vitality is growing, however so are threats to the power grid. Utility regulators are attempting to provide you with methods to manage, and Texas — the largest vitality producer in the US — might present essential classes.
Nonetheless, Texas has some distinctive components at play.
Texas leads the US in oil and natural gasoline manufacturing, but it surely’s additionally primary in wind power. Photo voltaic manufacturing in the state has nearly tripled in the previous three years. A part of the purpose is that Texas is especially suited to renewable vitality on its grid. Wind generators and photo voltaic panels in Texas have a excessive diploma of “complementarity,” so shortfalls in a single supply are typically matched by will increase in one other, smoothing out power manufacturing and decreasing the want for different turbines to step in. That has eased the integration of intermittent vitality sources on the grid.
Coal, in the meantime, has misplaced more than half of its share in Texas since 2006. For a very long time and throughout a lot of the nation, the story was that low-cost natural gasoline from hydraulic fracturing was consuming coal’s lunch on the power grid. Coal was additionally going through harder environmental rules like stricter limits on mercury, requiring coal power vegetation to improve their tools, and elevating electrical energy manufacturing prices.
“The mix of the environmental rules that are tightening and the cheapness [of competitors] imply that coal has hassle competing in the market,” stated Michael Webber, a professor of vitality sources at the College of Texas at Austin.
However in Texas, natural gasoline’s share of the electrical energy combine has been holding round 40 % for more than a decade. On the different hand, renewable vitality has surged as coal withered. Wind alone began beating out coal in 2019 and is now the second-largest supply of electrical energy behind natural gasoline in the state.

An necessary issue is that the state has its personal inner power grid, serving 26 million prospects and assembly 90 % of its electrical energy demand. It’s managed by the nonprofit Electrical Reliability Council of Texas, or ERCOT. In the freewheeling Texas vitality market, the least expensive sources of electrical energy grow to be dominant, and wind and photo voltaic — with low development prices, speedy construct instances, and nil gas bills — have emerged as winners.
Some Texans are additionally going out of their approach to purchase renewable electrical energy. Utilities like Austin Power provide prospects the alternative of paying further to purchase wind and photo voltaic power, and hundreds have executed so. “As a public utility, Austin Power’s decades-long shift in direction of renewable vitality displays the priorities of our prospects and our metropolis,” Matt Mitchell, a spokesperson for Austin Power, stated in an e mail.
Since there are few grid connections to different states, the Texas power grid avoids federal oversight, giving Texans more flexibility in setting their very own guidelines. The draw back is that Texas has a tough time getting further juice when its personal dynamos lose steam.
That was starkly evident in February 2021 when Winter Storm Uri chilled big swaths of the United States. In Texas, more than 4 million prospects misplaced power as temperatures dipped beneath these in Alaska. The official dying toll was 246, although some estimates place the quantity greater.
The blackouts resulted largely from frozen coal piles and natural gasoline pipelines, stalling the circulate of gas into power vegetation. Nonetheless, Texas Republicans, together with Gov. Greg Abbott, blamed wind power for the disaster.
Some lawmakers are now working to tilt the steadiness towards fossil fuels. “There are totally different political figures who are attempting to incentivize gasoline power vegetation or deny, prohibit, or inhibit renewables,” Webber stated.
Final yr, the Texas legislature handed a legislation that will stop the state’s retirement and funding funds from doing enterprise with firms that “boycott” fossil fuels.
Texas Lt. Gov. Dan Patrick stated certainly one of his legislative priorities for this yr is to safe more assist for natural gas-fired technology. “We’ve got to stage the enjoying area in order that we entice funding in natural gasoline vegetation,” Patrick stated throughout a press convention final November. “We are able to’t go away right here subsequent spring except we’ve got a plan for more natural gasoline power.”

He could get his approach. With current winter storms in thoughts, the Texas Public Utility Fee, which regulates electrical energy, is now contemplating proposals for reform the electrical energy market to spice up reliability. This month, the fee authorized a proposal that’s ostensibly technology-neutral, however could find yourself favoring natural gasoline vegetation.
Whereas wind and photo voltaic power are ascendant, they are intermittent, and regulators want to ensure there may be sufficient dispatchable power like natural gasoline to ramp up on nonetheless, cloudy days. The brand new proposal would create a credit score scheme that will encourage more of those dispatchable vegetation to return on-line and lengthen a lifeline to some current turbines that are struggling to compete. However it might additionally increase the prices of electrical energy manufacturing.
Environmental teams like the Sierra Membership famous that the proposal leaves the door open for different techniques for balancing electrical energy provide and demand, like vitality storage, growing vitality effectivity, and demand response.
Whereas Texas regulators hammer out the particulars of those reforms, the remainder of the nation ought to concentrate. With local weather change pushing common temperatures upward, the US power grid is more pressured than ever, not solely from rising demand and struggling provides, however from excessive climate damaging infrastructure. Clear vitality sources could also be more plentiful than ever, however so are the threats to the power grid.
