A power plant is a type of industrial facility that uses primary energy to generate electricity. Most power plants employ one or more generators that convert mechanical energy to electrical energy in order to supply electricity to the electrical grid for societal needs. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. Like every other facility, though this industry generates electricity, the facility itself has canteen and in some offices or areas which has ductworks, ventilations and even water. If you are reading this then you would know that buildings as such do require cleaning services. Acoustics/noise, air quality, ventilation, water, temperature, and space are the main aspects of a building that needs regular cleaning. These are discussed in greater detail in each service.
