How Solar and Batteries Stabilized Texas’s Grid This Summer

This summer, Texas experienced record-breaking energy demands as extreme heat waves swept across the state, with temperatures consistently exceeding 100 degrees Fahrenheit. In previous years, the Electric Reliability Council of Texas (ERCOT) would respond to such conditions with conservation requests, asking residents to limit their power usage to prevent strain on the grid. In 2023, ERCOT issued 11 conservation alerts. However, despite similar conditions this summer, ERCOT has not asked Texans to conserve power, a major shift from last year’s pattern.

So, what changed? Energy experts and grid operators point to the rapid growth of solar energy and large-scale battery storage as critical factors that have kept Texas’s power grid stable.

The Growth of Solar Power in Texas
Texas has seen an unprecedented boom in solar power production. On a single day in August 2024, the state’s solar farms generated 20,832 megawatts of power—the highest production of solar energy in Texas history. To put that into perspective, 1 megawatt can power about 250 homes during times of peak demand. This extraordinary output doesn’t even account for the energy produced by residential solar panels on homes and businesses across the state, which further bolsters Texas’s energy resilience.

This growth in solar capacity is vital in Texas, where scorching, sunny days lead to higher electricity consumption as air conditioners run at full blast. These same conditions also create the perfect environment for generating solar power, making it a natural solution to the state’s energy needs. Solar power doesn’t just reduce strain during the day, either. Excess energy from solar farms is stored in large batteries, allowing that energy to be fed back into the grid after sunset, when demand is still high but solar production has ended.

Utility-Scale Batteries: The Game-Changer
While solar energy generation has been essential, the state’s expanding battery capacity has also played a pivotal role. This summer, Texas set new records for power storage from utility-scale batteries, surpassing the previous record by an impressive 25%. According to Doug Lewin, author of The Texas Energy and Power Newsletter, this additional battery storage likely prevented rolling blackouts, as it provided a critical cushion during times of peak demand.

In fact, many experts agree that without these large-scale battery installations, Texas may have faced grid emergencies this summer. These batteries store surplus energy generated during sunny periods and release it during times of peak usage, balancing the supply-demand equation and keeping the grid stable.

The Business Opportunity Behind Solar and Battery Growth
Why the sudden surge in solar and battery investments? The answer lies in the increasing demand for energy in Texas. Over the past few years, Texas has experienced rapid population growth and industrial expansion, leading to a spike in electricity consumption. This increase in demand, coupled with frequent energy shortages, has created a lucrative market for solar farms and battery storage facilities. These businesses can quickly set up shop and provide much-needed relief to the grid.

Additional Factors Stabilizing the Grid
Solar and batteries are not the only factors that have contributed to Texas’s stable grid performance this summer. ERCOT CEO Pablo Vegas highlighted that strong evening winds have also brought more wind power online as the sun goes down, complementing the solar power and stored battery energy. Additionally, natural gas power plants have operated without major breakdowns, which could have otherwise exacerbated grid strain.

By combining solar power, battery storage, wind energy, and natural gas, ERCOT has been able to meet the state’s energy demands without asking residents to reduce their consumption, even during record-breaking heat waves.
