As Homer City became less competitive economically and was dispatched for load following – that is, it adjusted its power output as demand for electricity fluctuated – rather than for baseload power, the plant generated less electricity, and its capacity factor dropped.

The Homer City plant operated at an annual capacity factor of 82% in 2005. By 2022, the capacity factor had dropped to 20%, contributing to the decision to retire the plant, along with “the low price of natural gas, a dramatic spike in the cost of its ongoing coal supply, unseasonably warm winters, and increasingly stringent environmental regulations,” according to William Wexler, CEO of Homer City Generation, in a written statement.
