U.K. Coal Plants Killed Off One by One as Profit Declines: Chart

Coal’s days in U.K. power are numbered. By the end of March, SSE Plc will probably have closed almost all its coal generation in the U.K. after the clean-dark spread, a measure of the profitability of burning the fuel, turned negative. Margins were hit by a 25 percent drop in power prices in the past year and an 88 percent increase in April in a carbon tax to help fight global warming. The government plans to close all stations burning coal by 2025.
