Texas Firm Invests $1.7B in Massive Solar Farm at Coal Site

A Texas coal plant is getting a sunny second act as the future home of one of the nation's largest solar energy projects.

Energy investment firm Panamint is putting $1.7 billion toward Big Rooter Power, a massive solar complex in Robertson, Texas that will add 1.2 gigawatts of clean energy to the grid. The smart part? Building next to the existing Twin Oaks coal plant lets them use tens of millions of dollars worth of existing power lines and grid connections instead of starting from scratch.

"We believe deploying new capacity at existing energy sites is the clearest way to benefit communities, ratepayers, and the environment alike," said Apolka Totth, Panamint's CEO. The strategy saves money by building on "brownfield" sites that are already developed for industrial use rather than converting untouched land.

This approach is catching on nationwide. Similar projects in Illinois, Kentucky, and Louisiana are transforming old mining sites into clean energy hubs, proving that yesterday's industrial infrastructure can power tomorrow's renewable future.

The numbers behind Big Rooter are staggering. The first phase will bring 491 megawatts of solar panels online in August 2028. Phase two follows that December, adding another 658 megawatts by August 2029, plus 1.6 gigawatts of battery storage and 20 miles of new transmission lines.

Texas is already a renewable energy giant, producing 30% of America's wind power. That's three times more than runner-up Oklahoma and eight times California's wind output. The state also ranks second nationally in solar power, making Big Rooter a natural fit for the Lone Star State's energy ambitions.

The project qualifies for a federal investment tax credit covering 50% of costs. Smart planning let developers order long lead-time equipment like transformers early to take advantage of previous tax incentives.

The Ripple Effect

Big Rooter shows how America can build clean energy faster and cheaper by reimagining existing infrastructure rather than always starting fresh. Similar coal-to-solar transformations are popping up across the country, creating a template for rapid renewable expansion that benefits communities through lower costs and faster construction while putting existing industrial sites to productive new use.

When Big Rooter reaches full capacity in 2029, it will stand among America's largest solar projects, proving that Texas-sized ambition works just as well for renewable energy as it does for everything else.
