Harris County Commits $88.3 Million to Solar for All Projects

Commissioners Court on March 19 authorized $88.3 million to fund projects under the Solar for All plan despite the Environmental Protection Agency's attempted termination of grants associated with the program. The vote signals that Harris County intends to build out the initiative regardless of how its federal court battle unfolds.

Each site will carry a 2-to-5-megawatt capacity, for a total combined capacity of up to 40 megawatts of solar generation and at least 15 megawatt hours of battery energy storage. County staff are in the process of finalizing agreements with two contractors to deliver the projects: Big Sun Solar and SunGrid Power. Construction must begin by July 4 for the county to qualify for federal Investment Tax Credits, and representatives from both contracting firms told commissioners they are on track to meet that deadline.

The $88.3 million upfront investment, plus an additional $5.6 million in commercial paper financing, comes from Harris County's CIP fund, but officials said they anticipate reimbursement from federal tax credits and the pending EPA grant. Harris County anticipates an Investment Tax Credit reimbursement of about 40% of the total project cost, or approximately $36 million. If the federal grant does not come through, the county could pay off the debt with capital improvement program funds, and officials also noted the county expects to earn revenue from the sale of generated solar energy, which could offset upfront costs.

The county expects to connect approximately 10,000 households to the clean energy sources through retail electricity providers, with electricity use expected to decrease by about 20%, an estimated $468 in annual savings for qualifying households. The initiative aims to ease the financial burden of rising energy costs in vulnerable communities and enhance grid resilience during extreme weather events.

The stakes behind the county funding its own way forward are significant. The Texas Solar for All Coalition, composed of officials from Harris County and other state municipalities, was one of 60 applicants to receive EPA grants in April 2024, with the coalition awarded $249.7 million to fund projects across Houston, Dallas, Waco, San Antonio and Austin. Harris County specifically received $54 million for local energy initiatives. The federal government ended the program in August 2025 after the new presidential administration took office, calling the grants a "massive dilution of money."

Harris County Attorney Jonathan Fombonne told commissioners March 19 he is "cautiously optimistic" about their case in the ongoing lawsuit against the EPA, which includes the argument that the agency does not have authority to unilaterally terminate the Solar for All program, though he said the federal court may not deliver a ruling until the end of the year.

Precinct 3 Commissioner Tom Ramsey, who has previously spoken against redirecting funding from other capital improvements, directed county staff to identify the specific projects that would lose funding if Harris County does not secure the grant.

Harris County plans to have all of the clean energy projects in service by summer 2030. With litigation ongoing and a July construction deadline bearing down, the county is betting $88.3 million of its own money that the solar buildout cannot afford to wait for Washington.
