Medium load

from Wikipedia, the free encyclopedia
Daily course of electricity consumption (principle)

In power plant management, mean load denotes the area of ​​the daily load curve in which

  1. additional electricity is consumed beyond the base load and
  2. the characteristic of the electricity consumption is such that it can be covered by medium-load power plants. For short peaks in power consumption, very strong load increases or unforeseen power requirements, peak load power plants must then be added.

The load curve shows the course of power consumption over the 24 hours of a day. The base load indicates how much electricity is at least consumed around the clock. In the German power grid, the load increases during the day, between 6:00 a.m. and midnight, mostly above the base load in the range of the medium load. Power consumption is greatest during peak load times . They are usually between 7:00 a.m. and 12:00 p.m. in the morning and between 4:00 p.m. and 8:00 p.m. in the afternoon. Low load, on the other hand, refers to periods in which electricity consumption falls below the base load.

Medium load power plants

The normal periodic fluctuations in energy demand are covered by medium load power plants. They can be regulated better than base load power plants, which above all cover the constant energy demand. When their output is no longer sufficient, peak load power plants are used to cover these short-term energy requirements.

All thermal power plants can technically be operated at medium load. Examples of medium -load power plants are coal-fired power plants or gas and steam combined cycle power plants .
