Four medium voltage units were custom manufactured for a 1.3 gigawatt, 1300 (MW) coal-fired power plant station in Indiana. Built in the early 1950s, the facility is situated on 820 acres along the Ohio River. All six of its generating units are rated at 217.26 megawatts (MW), for a total capacity of 1,303.56 MW – enough to power a city of one million people. Those generators produce electricity at 15,500 volts while the transformers outside the plant step up the voltage to 345,000 volts so that it can be transmitted efficiently to customers.
