Two Coal Sites Futures: What Texas and Minnesota Tell Us About Solar’s Takeover
To illustrate the shift, let’s examine a pair of two coal sites—two major coal sites in these states. In fact, the story of Texas and Minnesota’s two coal sites—two sites in particular—can reveal how solar is replacing coal. Notably, major energy changes have centered around unique coal sites, and the fate of these two coal sites offers a signpost for clean energy directions.
The American energy grid is changing faster than ever. Specifically, two massive projects made headlines this week in July 2026. These projects involve two coal sites, each at a turning point. One project is in the heart of Texas. The other is in the cold plains of Minnesota. Both tell a story of solar power’s inevitable rise. However, they show two very different paths for the future of coal.
At Green Living Guy, we track these shifts closely. We focus on green living consulting services because the grid affects everyone. Consequently, understanding these projects helps us see where our energy comes from. Let’s dive into the contrast between the “Big Rooter” in Texas and the “Sherco Hub” in Minnesota.
Texas: The Additive Approach at Big Rooter
In Robertson County, Texas, Panamint Capital is building something huge. Specifically, the Big Rooter Power project is a 1.2 GWdc solar farm, representing a significant advancement in renewable energy. This $1.7 billion investment uses two million First Solar panels, which play a crucial role in harnessing sunlight to generate clean power. Furthermore, these panels are made right here in the US, ensuring that the project not only supports sustainable energy but also contributes to the local economy by reducing reliance on two coal-fired power plant sites.
The project is massive in scale. For instance, it uses 34,000 tons of American-made steel. It also creates over 800 construction jobs. Phase 1, called Big Rooter West, will go online in August 2028. Subsequently, Phase 2 will follow in 2029.
Tales of Two Coal Sites
However, there is a catch. The Big Rooter project sits right next to the Twin Oaks power station, which is a 310 MW lignite coal plant. Interestingly, there are no plans to retire the coal plant yet, and in fact, it is one of two coal sites in the vicinity. Instead, the developers are adding solar and batteries to the existing grid connection to facilitate a more sustainable energy mix while continuing to operate both coal sites.
This project also includes 790 MW of data center capacity. Therefore, the solar power will feed the growing demand for AI and computing. Panamint calls this “getting more out of America’s energy infrastructure.” In other words, they are stacking clean energy on top of old coal.
Minnesota: The Replacement Model at Sherco Hub
Meanwhile, Minnesota is taking a different route. The Sherburne County Generating Station, or Sherco, was once a giant among energy producers. Specifically, it was the biggest coal plant in the state at 2.2 GW, standing alongside other notable coal sites that have powered the region. It has been a landmark since the 1970s, symbolizing both the state’s industrial past and the ongoing transition to more sustainable energy sources.
However, Xcel Energy is moving on. They recently completed 710 MW of solar at the site. If Phase 4 is approved, that number will jump to 910 MW. Consequently, this solar power is actively replacing the coal units as they retire, specifically targeting two coal sites that are nearing the end of their operational lives.
Sherco Unit 2 is already gone. Unit 1 will follow soon. Finally, Unit 3 will close by 2030. This is a true transition. Specifically, Xcel is installing 600 MW of lithium-ion batteries. They are also testing a 10 MW iron-air battery from Form Energy. This “multi-day” storage is key for a reliable grid.
Furthermore, a new transmission line called the Minnesota Energy Connection will deliver up to 4,000 MW of renewables. As a result, the Sherco site is transforming from a coal burner into a clean energy engine.
The Economic Reality of 2026 for Two Coal Sites
Why is this happening now? The answer is simple: economics. According to the US EIA, renewable energy accounted for over 30% of US capacity in early 2026. Specifically, utility-scale solar output grew by 21.6% year-over-year.
In contrast, coal output fell by 10.9% during the same period. Even with political support for coal, the market is decisively choosing solar energy. Consequently, coal is becoming too expensive to run, particularly for two coal sites that previously relied heavily on this resource. For example, Sherco was consuming 9 million tons of coal per year. Replacing that with solar and batteries not only yields significant environmental benefits but also saves money in the long run. As these transitions take place, the shift from two coal sites to renewable energy will continue to gain momentum.
Businesses are noticing this trend. Many are looking into energy financing for going green to lower their costs. Therefore, the transition isn’t just about the environment. It is about the bottom line.
Solving the Infrastructure Bottleneck
As we see in both Texas and Minnesota, the tech is ready to transform the energy landscape significantly. Solar panels are efficient, harnessing sunlight to produce clean energy, and their adoption is gradually increasing across various regions. Batteries are getting cheaper and more effective, allowing us to store energy generated during sunny days for use when the sun isn’t shining. However, the bottleneck remains the grid; without the necessary infrastructure, even the best technologies will struggle to meet demand. Specifically, we need more transmission lines to carry the energy from solar farms to urban centers effectively and better interconnection between different energy sources to enhance reliability and stability of the power supply. This integration is crucial to ensuring that renewable energy can meet the ever-growing demand effectively and sustainably, paving the way for a greener future.
The Texas project succeeds because it uses an existing connection. Similarly, the Minnesota project succeeds by building new lines to deliver wind and solar. As experts recently noted regarding electric trucks, the technology is no longer the problem. Instead, the challenge is logistics and grid capacity.
Therefore, we must focus on upgrading our wires. If we don’t, all this clean power will have nowhere to go. Fortunately, projects like Sherco and Big Rooter are leading the way.
Two Coal Sites to Transition the Path: all to the Same Goal
Ultimately, Texas and Minnesota show us two ways to reach a clean energy future. Texas is adding renewables to the mix without killing coal immediately. Minnesota is aggressively swapping coal for solar.
Both approaches prove that solar is taking over. Whether we stack it or swap it, the results are the same. We are moving toward a cleaner, more resilient grid. At Green Living Guy, we believe this is the most exciting time in energy history.
Stay tuned as we continue to track these massive shifts. The sun is rising on a new era of American power.
