ERCOT Urges Texans to Conserve Power Amid First Major Heat Wave of the Season

Austin, TX — As temperatures soared above 100°F across much of Texas during the week of June 10, 2024, the Electric Reliability Council of Texas (ERCOT) issued its first conservation notice of the summer. The grid operator urged residents and businesses to reduce electricity usage during peak hours due to high demand and tight operating reserves. Though no rolling blackouts occurred, officials warned that similar conservation calls could be necessary in the weeks ahead. Texans responded by adjusting thermostats and limiting appliance use to help prevent strain on the power grid.

The heat wave, which saw temperatures exceeding 100°F in many areas, led to a significant surge in electricity demand, primarily due to increased air conditioning usage. ERCOT reported that the state’s power grid experienced its highest demand of the season, reaching levels close to the all-time peak set in August 2023. Despite the high demand, the grid remained stable, thanks in part to the public’s response to conservation requests and the integration of renewable energy sources.

ERCOT’s conservation notice specifically requested Texans to voluntarily reduce electricity consumption between 3 p.m. and 9 p.m., the period of highest demand. Suggested measures included raising thermostats by a few degrees, postponing the use of large appliances, and turning off non-essential lights and electronics. These steps aimed to alleviate stress on the grid and prevent potential outages.

In recent years, Texas has made significant investments in renewable energy, particularly solar and wind power, which have bolstered the grid’s capacity during peak times. Additionally, the state has expanded its battery storage capabilities, allowing for better management of energy supply and demand fluctuations. These advancements have played a crucial role in maintaining grid reliability during extreme weather events.

Looking ahead, ERCOT officials cautioned that continued high temperatures and increased energy consumption could necessitate further conservation appeals. They emphasized the importance of public cooperation in managing electricity usage to ensure the stability of the power grid throughout the summer months.
