In a significant shift for Texas’s energy landscape, the Electric Reliability Council of Texas (ERCOT) is poised to witness a groundbreaking milestone in 2026: utility-scale solar power is expected to outstrip coal generation for the first time. This transition from fossil fuels to renewable energy poses both exciting opportunities and critical considerations for small business owners who rely on electricity.
The latest forecast from the U.S. Energy Information Administration (EIA) predicts that solar generation in ERCOT will hit an impressive 78 billion kilowatt-hours (BkWh) in 2026, dwarfing coal’s anticipated 60 BkWh output. This momentous change is not just a win for renewable energy advocates; it also signals a shift in how businesses in Texas might approach their energy consumption and sustainability efforts.
Notably, solar energy’s share of the generation mix has blossomed, increasing from a mere 4% to 12% between 2021 and 2025, while coal has seen a decline from 19% to 13%. Meanwhile, natural gas continues to be the leading source of electricity in ERCOT, contributing to approximately 44% of the total generation during that same period.
For small business owners, this evolution in the energy sector offers tangible benefits. As solar capacity ramps up, the decreased reliance on coal could lead to stability in energy prices in the long run. More importantly, the growing prevalence of solar energy opens avenues for businesses to bolster their sustainability credentials. Companies that incorporate solar energy into their operations can not only reduce utility costs but also enhance their brand image, appealing to the growing number of environmentally conscious consumers.
"With ERCOT increasingly meeting rising demand through renewable energy sources, we anticipate that approximately 40% of total solar capacity additions in the U.S. will occur in Texas this year," stated Jonathan Church, principal contributor at EIA. He further highlighted the Tehuacana Creek 1 Solar and Battery Energy Storage System (BESS) project — the largest solar photovoltaic project slated to come online in 2026, with a capacity of 837 megawatts (MW).
This project exemplifies the shift towards not only solar generation but also the integration of battery storage solutions, enabling businesses to harness solar power even during non-sunny hours. Battery systems can store energy produced during the day for use during peak hours, potentially minimizing energy costs further.
While the outlook for solar energy in Texas is promising, small business owners should be aware of potential challenges that may arise as the energy landscape evolves. Although solar generation is forecasted to exceed coal on an annual basis in 2026, ERCOT’s mixed-energy portfolio implies ongoing fluctuations in energy output. Business owners should prepare for scenarios where energy supply may not always meet demand, particularly during peak periods.
Additionally, as more solar projects roll out, competition for this renewable source may intensify. To effectively capitalize on the benefits of solar energy, small businesses might consider investing in their own solar installations or exploring partnerships with local energy providers to secure advantageous energy rates.
Looking forward, forecasts predict that solar generation in ERCOT will continue its upward trajectory. In 2027, annual solar generation is expected to reach 99 BkWh, while coal generation is projected to dwindle to 66 BkWh. Yet as the energy landscape shifts, small business owners must stay informed and adaptable.
As Texas embraces this clean energy revolution, small businesses stand at the forefront of an energy transformation. The benefits range from lower energy costs and improved sustainability credentials to innovative solutions like battery energy storage. By preparing for both opportunities and challenges, small business owners can position themselves advantageously in a rapidly changing market.
