In 2018, the national average sales price of coal at coal mines was per short ton, and the average delivered coal price to the electric power sector was per short ton, resulting in an average transportation cost of per short ton, or about 8% of the delivered price.
cycling costs for conventional fossil generation in this report. The report also lists the typical cycling cost of the "flexible" power plants, as it is important to realize that while such plants are built for quick start and fast ramping capabilities, they are not inexpensive to cycle. There is still a cost to cycle such plants.
Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
