Spearmint Energy Lands $450 Million Financing for Texas Battery Storage Project

• Spearmint Energy secured approximately $450 million in financing for its Red Egret battery storage project in Texas.
• The standalone battery energy storage system will deliver 300 MW / 600 MWh of capacity in Texas City.
• Andrew Waranch, Founder and CEO of Spearmint Energy, said the project is focused on strengthening grid reliability across the Texas Gulf Coast.

What the Red Egret Financing Includes

Spearmint Energy has officially closed a major financing package to fund the construction of Red Egret, a large-scale battery energy storage project planned for Texas City, Texas. The financing totals roughly $450 million and includes a $225 million construction facility, approximately $126 million tied to investment tax credit transfer commitments, and an additional $96 million in preferred equity investment from Nuveen Energy Infrastructure Credit. The transaction represents another major capital raise within the rapidly growing U.S. battery storage sector as developers continue scaling infrastructure tied to grid reliability and renewable energy integration.

What the Texas Battery Storage Project Will Deliver

Once completed, Red Egret will operate as a standalone Battery Energy Storage System with 300 MW / 600 MWh of capacity. The project is intended to help stabilize power delivery across Texas City and the broader Gulf Coast region by storing and dispatching electricity during periods of high demand or grid stress. Large-scale battery storage projects have become increasingly important across Texas as population growth, industrial expansion, and weather-related grid challenges continue driving demand for more flexible energy infrastructure.

What the Financing Structure Says About Energy Investment Trends

The financing package reflects the increasingly sophisticated capital structures now supporting major clean energy and battery storage projects. The construction financing was arranged by a consortium of banks led by First Citizens Bank and Investec, alongside participation from Nord/LB and East West Bank. The use of transferable investment tax credits also highlights how federal clean energy incentives continue playing a major role in accelerating infrastructure investment across the energy sector.

What This Means for Spearmint Energy’s Growth

According to Founder and CEO Andrew Waranch, the Red Egret development is part of Spearmint Energy’s broader effort to improve energy reliability while delivering cost-effective power infrastructure across Texas. Upon completion in 2027, the project is expected to push the company’s total operating battery storage capacity above 1.5 GWh across four projects. The Florida-based company currently operates significant battery infrastructure within ERCOT while continuing to expand its national project pipeline.

What the Industry Will Watch Next

Battery storage remains one of the fastest-growing sectors within U.S. infrastructure and energy development as utilities, grid operators, and private developers work to modernize aging power systems. Texas, in particular, has emerged as one of the country’s largest battery storage growth markets because of its independent power grid, expanding renewable generation, and rising electricity demand. For infrastructure investors, transactions like Red Egret continue demonstrating strong institutional appetite for large-scale energy transition assets backed by long-term grid demand and federal incentives.
