Reducing cycling costs in coal fired power plants through ...

Nov 16, 2016· The more frequent cycling of coal-fired power plants can cause thermal and pressure stresses. Over time, these can result in premature or unplanned component failure and increased maintenance. Repeated starting up and shutting down of a unit, or operating at part load, can also increase emissions compared to non-cyclic operation.

Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load ...
