What ERCOT’s New Report Signals About the Future of Texas’ Power

Blog in Brief

  •  Texas demand growth is outpacing the rest of the U.S., with ERCOT serving record load and projecting sustained increases driven by data centers and large industrial users  

  • The grid is reliable but entering a more complex phase, with aging assets, increased reliance on renewables, and tighter reserve margins  

  • Massive investment is underway across generation, storage, and transmission, including thousands of miles of new high-voltage lines 

  • State officials are making consequential changes to policy and market design 

  • Texas remains one of the most dynamic and business-friendly power markets, but success will depend on aligning policy, infrastructure, and stakeholder coordination

The Electric Reliability Council of Texas (ERCOT) is managing the fastest demand growth in the country, fueled by expansions of data centers, industry, and population. While this growth is a win for Texas’ economy, it introduces planning challenges. ERCOT’s latest report makes one thing clear: The state’s power grid is keeping up for now, but the margin for error is shrinking fast.

Maintaining Reliability Amid Shifts to Power Mix and Policy

According to ERCOT, Texas has experienced an incredible 5 percent energy growth rate since 2021. But it’s handling that growth: In 2025, it added 16,000 megawatts (MW) of supply (mostly from solar and battery storage) and built or upgraded more than 500 miles of transmission lines. However, a significant portion of dispatchable generation is aging, and renewables introduce variability that complicates assurance of energy reliability. 

Large-load interconnection alone is reshaping how the grid is studied, built, and operated. These large-load (≥75 MW) interconnection requests now constitute over 70 percent of the more than 450,000 MW of interconnection requests as of January 2026. After state lawmakers passed SB6 last session, the state is determining how to ensure that market participants like data centers and cryptocurrency miners pay their fair share.  The Public Utility Commission of Texas (PUCT) has started proposing rules to change large-load interconnection standards, demand reduction, and other grid rules. So far, data center customers and developers and are hitting back on proposals that would charge them fees to study siting and interconnection,  while encouraging the PUCT to exempt existing large-load applicants from the new costs.

ERCOT and state leaders are innovating with additional market reforms. They’ve approved new 765-kilovolt transmission lines and initiated a policy called  Real-Time Co-optimization Plus Batteries (RTC+B), which is expected to improve battery storage’s integration and operational efficiency. 

What It Means for Companies in Texas

For energy developers and end-users, the takeaway is straightforward: Engagement matters. Whether it’s navigating interconnection, understanding new regulations, or gaming out project costs, proactive stakeholders will be best positioned to operate and grow in Texas. Despite geopolitical challenges, the state continues to set the pace for energy growth in the U.S. Each Texas legislative session (the next one starts in January 2027) brings innovative reforms to energy and infrastructure policy.  That’s why a robust public affairs strategy is critical to ensure greater coordination between policymakers, operators, the private sector, and communities. With a winning strategy, organizations can influence favorable outcomes across this rapidly evolving grid.
