The coal fleet has been the foundation of the American electricity grid and continues to be an integral part of the evolving energy landscape. Currently, the coal fleet is responsible for over 20 percent of U.S. electricity needs.  With an infrastructure network that includes a complex transmission system, and access to highways, railways,  and waterways, the coal fleet provides consistent, dispatchable, fuel-secure power on a 24/7 basis.  It is critical to maintaining affordable electricity prices, and a reliable and resilient electricity grid.
