The powerhouse accommodates electromechanical equipment, such as the turbine, generator, and control panels. Sometimes in micro hydro power plants, agro-processing units are also incorporated. The main function of the powerhouse building is to protect the electromechanical equipment from adverse weather as well as possible mishandling or vandalism of the equipment by unauthorized persons. The powerhouse should have adequate space such that all equipment can fit in and be accessed without difficulty. The generators, turbines, and other accessories need to be securely fixed on the machine foundation in the powerhouse. This requires a careful design because the equipment generates dynamic forces, and even a slight displacement can cause excessive stresses on various parts and lead to equipment malfunction.
