Cleveland Public Power

Cleveland Public Power's three hundred megawatt system ranks as the largest municipally owned electric utility in the State of Ohio and one of the largest in the United States. Cleveland Public Power's electrical footprint extends throughout the City of Cleveland, providing service to the nearly 80,000 residential, commercial and industrial customers. This system is comprised of three 138 kV interconnections, allowing for access to electrical power available on the market. The 138 kV circuit feeds the 36 substations located throughout the City, which in-turn, step down load to a distribution system of 69 kV, 13.8 kV, 11.5 kV or 2300 volts, depending on the substation. It is a system that features state-of-the-art technology throughout the network with its automated switchgear and relays located at the substations, to the System Controls and Data Acquisition System (SCADA) that provides real-time information through telemetry. System control is highly automated with voltage regulation through Capacitor Banks and Load Tap Changers. Most of its power and energy requirements are obtained through short and long-term contracts with various regional utilities and other power suppliers through three 138 kV interconnections to the regional grid. The balance is made up through three combustion turbine generating units and ten diesel generators located throughout the network.
