Textbook discussions of American industrialization often begin with New England's water-powered textile mills. By the 1830s, though, large-scale coal extraction had begun in Pennsylvania, Virginia, and beyond. Northern railroads and factories took the lead in replacing wood and water power with coal.

Capacity. Normal ability to produce metals in a given time period. This rating should include maintenance requirements, but because such service is scheduled to match the needs of the machinery (not those of the calendar), a mill might run at more than 100% of capacity one month and then fall well below rated capacity as maintenance is performed.

All mill capacities are based on a standard coal with HGI = 50. The larger the value for HGI, the easier it is to grind the coal, resulting in a higher mill capacity. An HGI of 35 reduces the mill capacity about 20%. Coals with HGI less than 35 can be pulverized, but mill capacities are reduced significantly.
