Panamint Capital Breaks Ground on 1.2 GW Solar Project in Texas

Panamint Capital has broken ground on the Big Rooter Power solar project, a 1.2 GWdc development located at its Twin Oaks power station site in Robertson County, Texas. Positioned roughly halfway between Dallas and Houston, the project is identified as the largest solar facility constructed on a former coal mining site in North America.

Construction is currently underway for the initial phase, Big Rooter West, which will have a capacity of 491 MWdc and is scheduled to begin commercial operation in August 2028. The second phase, Big Rooter East (658 MWdc), is expected to start construction in December 2026, with commercial operation anticipated in August 2029. The combined project is projected to create over 800 construction jobs.

The initiative aims to transform the historic Texas energy site into a hub for next-generation power and digital infrastructure. By leveraging existing infrastructure, the project intends to address increasing electricity demand and extend the economic value of assets that have historically powered the region. The development also includes plans for 1.6 GWh of battery energy storage and 790 MW of data center capacity.

For the project's execution, Panamint Capital has partnered with U.S. renewable energy firms. SOLV Energy will provide EPC services for the solar, substation, and transmission infrastructure. First Solar will manufacture approximately two million solar panels, and Nextpower will supply its solar tracker systems. The project will incorporate over 34,000 tons of domestically manufactured steel.
