Coal-to-Clean Price Index

Coal-to-Clean Price Index (CCPI) is an open data project that tracks the operating cost of coal and gas versus the cost of new onshore wind or utility-scale solar PV plus four hours of battery storage in 25 countries. CCPI represents around 90% of global coal and over half of gas capacity, respectively. CCPI can be used to shape the debate about the cost-competitiveness of zero-carbon technologies, especially during periods of fossil fuel price volatility.
