Load following power plant : ウィキペディア英語版 | Load following power plant A load following power plant, also known as mid-merit, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day.〔Renewable and Efficient Electric Power Systems By Gilbert M. Masters p. 140〕 Load following plants are typically in-between base load and peaking power plants in efficiency, speed of start up and shut down, construction cost, cost of electricity and capacity factor. ==Base load and peaking power plants==
Base load power plants operate at maximum output. They shut down or reduce power only to perform maintenance or repair. Base load power plants include coal, fuel oil, almost all nuclear, geothermal, hydroelectric, biomass and combined cycle natural gas plants. Peaking power plants operate only during times of peak demand. In countries with widespread air conditioning, demand peaks around the middle of the afternoon, so a typical peaking power plant may start up a couple of hours before this point and shut down a couple of hours after. However, the duration of operation for peaking plants varies from a good portion of the waking day to only a couple dozen hours per year. Peaking power plants include hydroelectric and gas turbine power plants. Many gas turbine power plants can be fuelled with natural gas or diesel. Most plants burn natural gas, but a supply of diesel is sometimes kept on hand in case the gas supply is interrupted. Other gas turbines can only burn either diesel or natural gas.
