The acquisition of the Evelyn Battery Energy Storage project by GridStor marks a significant stride in addressing Texas's growing energy demand and grid stability concerns. The project's strategic location near Houston, a hub with notable congestion issues, indicates a tactical move to alleviate energy delivery challenges. This development aligns with the Electric Reliability Council of Texas (ERCOT) forecasts, which predict a substantial increase in peak power demand.

The integration of a large-scale battery storage facility is pivotal, as it provides a buffer against power outages and supports load balancing during peak hours. The potential impact on the energy market includes increased trading activity in ERCOT's electricity market, potential shifts in energy prices due to improved supply during high-demand periods and a reduction in congestion costs. Furthermore, the project's construction phase is expected to create employment opportunities, which could have a positive ripple effect on the local economy.

GridStor's initiative reflects a broader industry trend towards renewable energy solutions and grid modernization, with battery storage being a cornerstone technology. The operationalization of the Evelyn project by Spring 2025 will contribute to Texas's energy resilience, particularly in light of recent extreme weather events that have stressed the grid. The deployment of such storage systems is essential for the integration of intermittent renewable energy sources, as they can store excess energy and release it when solar or wind generation is low.

From a sustainability perspective, the project underscores the transition towards a clean energy landscape. It also demonstrates the role of private investment, as seen with Goldman Sachs Asset Management's backing, in accelerating the deployment of renewable infrastructure. The project's expected performance and reliability will be critical benchmarks for future investments in the sector.

The announcement of the upcoming construction of the Evelyn Battery Energy Storage project highlights the growing intersection between the energy sector and the construction industry. The engagement of leading suppliers and contractors suggests a focus on quality and reliability in the project's execution. The expected employment of 100 skilled tradespeople and apprentices indicates a boost to the local job market and the importance of skilled labor in the deployment of modern energy infrastructure.

Such projects often require specialized expertise in both construction and energy systems, which can lead to the development of a more skilled workforce. The long-term implications for the construction industry include potential growth in the sector specializing in energy storage facilities, which may lead to advancements in construction techniques and project management practices tailored to the unique demands of energy infrastructure projects.

450 MW / 900 MWh Texas acquisition expected to begin construction as early as Summer 2024

PORTLAND, Ore.--(BUSINESS WIRE)-- GridStor, a developer and operator of utility-scale battery energy storage systems, announced today that it has acquired an up to 450 MW / 900 MWh project in Galveston County, Texas from Balanced Rock Power. The Evelyn Battery Energy Storage project, which is slated to begin construction in Summer 2024, has an anticipated on-line date of Spring 2025.

The project is scheduled to go online at a critical time for Texas. The Electric Reliability Council of Texas (ERCOT) recently forecasted that summer peak power demand in the state will increase by another 5,000 MW by the end of the decade, with the potential for 16,000 MW of new peak demand during winter extreme weather.

“Battery storage is a scalable and near-term solution to powering historic load growth in Texas,” said Chris Taylor, CEO of GridStor. “Every day, batteries are consistently providing energy to stabilize the power system and meet hours of greatest demand in the state. The rapid deployment of battery energy storage is strengthening the Texas grid to support the growing needs of its residents and businesses today while new power sources and transmission infrastructure are built over the longer term. The quality site selection and early development completed by Balanced Rock Power position this project to contribute substantially to electric reliability in this rapidly growing load area in Texas.”

GridStor’s Evelyn project will be built near the existing Hidden Lakes substation owned by Texas New Mexico Power (TNMP), allowing the batteries to begin grid-connected operations quickly. The project will be near Houston, which suffers from congestion issues – the inability to deliver low-cost energy due to insufficient capacity. Once operating, the Evelyn project will increase the resilience of the Texas electric grid, helping ensure reliable power supply during disturbances and peak hours through participation in the electricity market managed by ERCOT.

Engineering and procurement are underway with leading suppliers and contractors preparing for on-site construction starting in the Summer of 2024. The project is expected to employ 100 full-time, skilled tradespeople and apprentices during its construction.

"We are committed to driving the adoption of clean energy across the United States," said John Knight, CEO of Balanced Rock Power. "Together with GridStor, we're building clean, reliable and affordable energy solutions today for a promising tomorrow."

GridStor develops and operates battery facilities directly integrated with American power infrastructure, storing electricity to deliver when it is most needed. GridStor is backed by Goldman Sachs Asset Management and comprises a team of seasoned energy professionals with a record of past accomplishments in energy storage and clean energy project acquisition, development, finance and operations. GridStor’s target markets include regions seeing higher energy demand from unpredictable weather events such as extreme heat, and areas at risk of increasing grid instability due to retirements of older and aging grid infrastructure and power plants.

Balanced Rock Power is a boutique developer that specializes in the planning and development of utility-scale solar and energy storage projects to support the transition towards renewable energy, sustainability, and a clean energy landscape. Balanced Rock Power approaches development from a long-term owner point of view, including advance procurement of long-lead equipment to meet utility interconnection timelines.
