![]() Record power demand and other problems culminated this week when ERCOT issued a level 2 energy emergency alert, bringing Texas the closest it has been to statewide outages since the 2021 winter storm. HOW HAS THE SUMMER HEAT IMPACTED THE POWER GRID? When a bill to increase energy efficiency in new construction reached Abbott’s desk in June, the governor lumped it in with other vetoes while trying to pressure lawmakers into reaching a deal on property tax cuts. But skepticism remains.Įnergy experts say Texas isn’t doing enough to ease demand on the system. Greg Abbott has declared the changes have fixed “all of the flaws” that caused one of the largest power outages in U.S. ![]() But it’s not clear whether that will entice companies to build. Texas lawmakers also passed bills this year aimed at providing incentives for the development of more “on-demand” generation - not including renewables like wind or solar - to keep up with the state's fast-growing population. Significant changes included mandates for plants to weatherize for the cold. WHAT HAS TEXAS DONE SINCE THE 2021 BLACKOUT? This summer’s challenges have raised more questions about the power grid’s reliability and what more the Electric Reliability Council of Texas, the grid manager, should do to shore it up. ![]() The summer heat isn’t subsiding as high temperatures above 100 degrees Fahrenheit (37.8 Celsius) were expected in much of Texas through the weekend. Department of Energy granted an emergency order allowing Texas to temporarily suspend emissions rules so power plants could produce enough electricity to prevent outages. The grid's reliability has been questioned by residents and lawmakers since a deadly winter blackout in 2021 knocked out power to millions of customers for days and resulted in hundreds of deaths.Ĭoncerns were renewed this week after Texas’ power grid manager issued an emergency alert due to low reserves and high demand.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series.
