Their capacities range from a few kilowatts to hundreds of megawatts. This power output is ordinarily stated in watts or kilowatts. A power inverter will often have an overall power rating expressed in watts or kilowatts. Electric power is usually measured in kilowatts (kW). The plan calls for 365 wind turbines, each with a nameplate capacity of 850 kilowatts. Heater outputs are measured in kilowatts or BTU per hour. It had two Isotta Fraschini Delta RC.40 engines rated at 574 kilowatts (770 horsepower) each. The plant initially had a capacity of 500 kilowatts (KW). Ten microturbines run on landfill gas, producing 300 kilowatts of renewable energy for Burbank. Power generation began on June 30, with an initial capacity of 2,000 kilowatts (KW). Power is more commonly expressed as kilowatts (10 W, kW) or horsepower. Power is more commonly expressed as kilowatts (10 W, kW) or horsepower (hp = kW/0.746). It can be expressed in kilowatts or horsepower. It had a generating capacity of 7,500 kilowatts. This hydro-electric dam is capable of producing 8,000 kilowatts.
