What does a steel mill do?

Steel mills commonly cast and form sheets, billets, bars, blooms, pipes, ingots, and wires. A mill may also hot-roll or cold-roll steel during production. These processes create different shapes and finishes. Before shipment, the steel might be cut, spooled, or bundled before leaving the mill. In foundry or mill, steel may be heat treated.

What happened to the steel mill?

The steel mill helped fund parks and other infrastructure. But by the 1970s, as competition grew from steelmakers overseas, the mill started to slow down. Layoffs grew in the 1980s. By the late 1990s, the mill was no longer the largest in the state (Walmart took that mantle, with jobs that were much less well-paid).

How much energy will the Maine Energy Project store?

The project, with around 2,000 modules, will store 8,500 megawatt-hour of energy, or roughly enough power for around 70,000 homes for 100 hours. The Maine project will be built on another abandoned industrial site—a former paper and pulp mill.
