GridBeyond launches commercial optimization of 29.7 MW battery portfolio in ERCOT new co-optimized market

[August 20, 2026 Austin, Texas] GridBeyond, a global AI-powered energy technology company, has commenced commercial optimization for 29.7 MW of front-of-the-meter battery storage asset in Texas, providing AI-driven optimization, forecasting and Qualified Scheduling Entity (QSE) services for SmartestEnergy’s South Texas battery portfolio.

SmartestEnergy's "Texas Ten" PPA portfolio has begun withthree 9.9 MW battery energy storage systems located in Cotulla, Palmview and Edinburg, now actively participating in ERCOT’s real-time and day-ahead energy markets under GridBeyond’s optimization and QSE representation.

The announcement comes as battery storage operators adapt to ERCOT’s Real-Time Co-Optimization plus Batteries (RTC+B) market design, which went live in December 2025 and has changed how batteries participate in real-time energy and ancillary services markets. With energy and ancillary services now co-optimized in real time, and battery state of charge explicitly considered in market operations, asset owners require more sophisticated forecasting, bidding and dispatch capabilities to compete effectively.

Through its technology platform, GridBeyond combines AI-driven battery optimization, energy price forecasting, automated bidding and QSE scheduling. This full-stack approach enables each asset to be dispatched into the right market at the right time, maximizing revenue opportunities while managing degradation, state of charge and operational constraints.

GridBeyond's proprietary Bid Optimizer is purpose-built for this environment, leveraging advanced AI to simultaneously optimize across energy and ancillary service products, aligning market price forecasts with battery state-of-charge simulations. This helps battery owners and investors respond to market volatility, capture stacked revenue opportunities and improve long-term asset performance.

Sean McEvoy, US President & Chief Product Officer at GridBeyond, said: " Battery storage is becoming significantly more sophisticated. Success in ERCOT is no longer determined simply by market participation, but by the ability to make thousands of optimization decisions across multiple value streams while respecting asset constraints. Bringing these three BESS projects into commercial operation in ERCOT demonstrates the strength of our platform and our ability to deliver full-service solutions across multiple US ISO markets. Our team in Austin delivers real-time optimization, market forecasting, and QSE services to help asset owners capture greater long-term value in one of the world’s most dynamic power markets."

Gavin Baker, VP Trading and Origination, SmartestEnergy US, said, "As ERCOT's market continues to evolve, having the right optimization strategy and market expertise is critical to maximizing the value of battery storage assets. Our continued collaboration with GridBeyond reflects our shared commitment to delivering innovative, data-driven solutions that help assets perform in an increasingly sophisticated market."

Across the U.S., GridBeyond provides optimization and market access services across CAISO, ERCOT, PJM, MISO, and SPP, managing a rapidly growing portfolio of utility-scale battery storage, large flexible loads, and renewable generation assets. With 5+ GW under management globally and 900+ MW of battery storage, the company continues to expand its North American footprint to meet rising demand for intelligent, technology-led asset management.

About GridBeyond
At GridBeyond, we believe that the future of energy should empower businesses, communities, and the planet. We exist because a resilient, decarbonised, and economically sustainable energy system is only possible when every asset, from renewables to industrial load, plays its part. Our mission is to accelerate the transition to net zero by enabling organisations to unlock the full value of their energy and contribute meaningfully to a cleaner, smarter, more balanced grid.

We achieve this by bridging the gap between energy assets and real-time markets. Our technology turns latent flexibility into tangible value, orchestrating renewable generation, battery storage, EV infrastructure, and industrial processes into a unified ecosystem of controllable, optimised resources.

GridBeyond provides an end-to-end suite of energy services built on our virtual power plant (VPP) and distributed energy resource management system (DERMS) capabilities.
