About IMPA

The Indiana Municipal Power Agency (IMPA) is a wholesale electric power provider serving the needs of 61 cities and towns in Indiana and Ohio. 

IMPA was formed so its member utilities could share power resources, allowing cities and towns to provide electricity more economically to their customers. The Agency began operations as a “joint action agency” in 1983 with 26 members. As individual utilities, IMPA members had limited access to power supply options.  By purchasing power from IMPA, instead of purchasing or generating it themselves, IMPA members found they could have a more reliable power supply, save money and keep electric costs as low as possible.

IMPA is governed by its members. Member utilities purchase their total power requirements from IMPA and deliver that power to the residents and companies in their service territories. Altogether, IMPA members deliver electric service to over 350,000 individuals throughout Indiana and Ohio.

IMPA’s diverse power portfolio consists of primarily the Agency’s own generating capacity and some purchased power.  IMPA’s active management of power costs and service quality has made it into one of the country's most competitive power providers.
