Xcel Energy, Colorado's largest utility, is embarking on a transition away from coal by closing its last coal-burning unit, Comanche 3, by 2031. This shift is part of the state's efforts to reduce emissions and promote cleaner energy sources. Xcel is set to submit its Pueblo Just Transition electric resource plan on October 15, aiming to support Pueblo's economy post-coal era. The plan includes possible projects to create new jobs and tax revenue in the region. The article discusses the swift departure from coal by Colorado's utilities, driven by the decreasing costs of wind, solar, and battery storage. Xcel's proposal for the future involves integrating more renewables, expanding transmission lines, using lithium-ion batteries for storage, and exploring innovative technologies like iron-air and pumped-storage hydro. Additionally, Xcel is considering green hydrogen production, carbon capture and storage, but views nuclear and enhanced geothermal as less feasible due to high costs. The utility acknowledges the growing demand for electricity, especially with the rise of electric vehicles and the need to replace natural gas in buildings. The article also highlights the potential impacts of climate change on Colorado's environment, emphasizing the importance of global solutions. Overall, Xcel Energy's plan for Pueblo showcases a positive outlook on transitioning to clean energy sources while fostering economic growth and addressing climate challenges.
