This is an executive summary report on the “Coal Plants in Transition: An Economic Case Study” prepared by Natural Capitalism Solutions in Colorado. The report makes a strong business case for energy providers to consider transitioning away from coal to a combination of renewable and energy efficiency technologies. The transition becomes cost effective and quite profitable when combined with revenue streams that result from selling pollution credits (NOx, SO2), carbon credits, water rights, and also fuel savings. The study specifically considers the Navajo Generating Station as an example. But the report is designed to provide information to utility managers all over the country who are faced with serious economic decisions regarding the future of their coal plants as we enter a carbon and water constrained world.
