A transformer functions as the “heart” of an electricity substation, according to a press release from Ameren Transmission Company of Illinois. Its function is to convert the voltage levels of electricity passing through the substation to the levels needed to power homes and businesses.
According to the ATXI release, benefits of the project for northeast Missouri will include improved electric system reliability, improved access to renewable energy sources, improved transmission capacity and increased annual tax revenue. Ameren officials say the approximate cost of the Zachary Substation is $25 million.
