They have been being increasingly used by business entities and individual investors and are designed to provide financial profits, which will be ensured only with correct operation of the energy system. One of examples of alternative energy sources application is the construction of small hydropower plants, where the efficiency of all elements included is of great importance. The article analyses financial losses incurred by owners of power plants when the energy system lacks 100% capacity of the inlet channel. Material that accumulates on SHP trash racks might be analysed in two ways: biologically (these are screenings – as in wastewater treatment plants) and hydraulically.
