Work on the initial stage of Panamint Capital’s 1.2 GW Big Rooter Power solar venture commenced in July at the Twin Oaks power station in Robertson County, Texas. According to the company, it will rank as the biggest solar installation ever built on land previously used for coal mining, as well as the largest brownfield renewable energy development in North America.
The energy infrastructure investor has just finalized the first tranche of a $1.8 billion green loan earmarked for construction. The $769 million initial portion will support continuing work on Big Rooter West, a 491 MW segment of the project. A second tranche exceeding $1 billion will fund Big Rooter East, the 658 MW latter stage.
Situated roughly midway between Dallas and Houston, Big Rooter Power occupies 1,804 hectares of reclaimed coal mine terrain and utilizes existing interconnection infrastructure at Panamint’s 349 MW coal-fired Twin Oaks Complex. The site integrates generation, surface mining, storage, data center capacity and high-voltage transmission.
Chief executive officer Apolka Totth stated that upon completion of Big Rooter, the Twin Oaks complex will host 1.5 GW of operating thermal and renewable capacity, plus more than 20 miles of new 345 kV transmission lines, 1.6 GWh of battery storage and 790 MW of Batch Zero data center capacity being developed across the 10,000-acre property.
Panamint said it has secured a long-term power purchase agreement with a corporate buyer that was not identified. Bill Stanton, the firm’s managing director of development, noted that the deal with one of the nation’s largest companies will guarantee that power produced at Big Rooter supports American job creation through the 2050s.
Building both Big Rooter West and Big Rooter East should generate more than 800 jobs, Panamint indicated. Big Rooter East, the 658 MW second stage, is scheduled to break ground in December 2026 and reach commercial operation in August 2029, with financial close anticipated during the first quarter of 2027.
Panamint says it is dedicated to working with domestic renewable energy suppliers. Solv Energy will handle EPC services covering solar, substation and transmission infrastructure. First Solar will supply roughly 2 million panels produced in Ohio, Louisiana and Alabama. Nextpower, based in California, will install its NX Horizon tracker systems featuring Hail Pro-75 and NX Navigator software. More than 34,000 tons of steel made in the United States will also be used, according to the company.
Panamint Capital, headquartered in Nevada, is a woman-led energy investment firm established in 2019 that operated 718 MW of generating capacity in 2025. Its sustainability report highlights the Twin Oaks station as an illustration of redevelopment work aimed at readying existing sites for utility-scale solar, storage and thermal projects, which the report describes as extending the productive use of existing infrastructure through clean energy investments that sustain local employment and generate long-term economic value in host communities.
