ABOUT IMPA
The Indiana Municipal Power Agency (IMPA) is a not-for-profit utility providing 61 communities with a wholesale power supply that is low-cost, reliable, and environmentally responsible.
IMPA was formed so its members could share power resources, allowing municipally-owned utilities 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, public power communities had limited access to power supply options. By joining together to purchase and generate power through IMPA, member communities found they could save money and keep electric costs as low as possible.
IMPA is governed by its members.
Member utilities purchase their 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 supply portfolio includes a mix of the Agency’s own generating capacity and purchased power. IMPA’s active management of power costs and service quality makes it one of the country’s most competitive power providers.
Where our power comes from.
IMPA is committed to providing member communities with environmentally responsible and locally generated electricity.
Our diverse power supply portfolio includes resources fueled by coal and natural gas as well as wind, solar, and nuclear. We invest in infrastructure to support our generation resources, creating jobs and economic opportunities for our members.
