What is IMPA? 
The Indiana Municipal Power Agency (IMPA) is the wholesale electric power supplier to 61 cities and towns across Indiana and Ohio. 
Who are IMPA's members? 
IMPA's members are municipally-owned electric utilities in 61 cities and towns in Indiana and Ohio.  The communities own and operate their own electric distribution systems and purchase generation and transmission service from IMPA. 
What are the benefits of being a member of IMPA? 
IMPA provides its member systems with a low-cost, reliable, environmentally responsible power supply.  In addition, the Agency assists members with power supply planning, engineering, economic development, government relations, marketing and communications services. 
How does IMPA meet its members’ electric needs? 
IMPA uses a portfolio approach to meet the electric needs of its members. This includes a combination of mostly IMPA-owned generation and some long-term, firm power purchases with some seasonal market purchases. IMPA conducts power supply studies regularly and monitors load growth to ensure it has ample generating or purchased power resources available to meet the growing needs of its member communities. 
Can any city or town join IMPA? 
Only cities or towns that own the electric distribution system in their community may become members of IMPA. There are 72 of these entities in the state of Indiana, and 60 of them are members of IMPA. 
Why do some municipals have an electric utility and others don't? 
Some cities and towns chose to purchase or construct their own electric distribution systems in order to locally control the delivery and cost of electricity to citizens and businesses. Those cities and towns in Indiana who do not own their electric utility are currently served by either an investor-owned utility (IOU) or a rural electric membership cooperative (REMC), as designated by state territory law. 
What is the difference between Public Power and municipal power? 
Municipal power systems are owned by the communities they serve.  Power systems can also be owned by other entities, including state governments and federal governments.

Why is Public Power more reliable? 
Public Power systems are typically more reliable because they are locally owned, operated and controlled. The individuals who work on the system live in the area and do not need to be dispatched from a remote location in the event of a service interruption. 
What is the difference between IMPA and a municipal utility? 
IMPA is a wholesale electric provider to municipal utilities. IMPA produces or purchases the electricity and then delivers the power to the member municipal utilities it serves.  The member municipalities then deliver the power to the residents and businesses in their communities.  
What is the difference between IMPA and an REMC? 
IMPA is a wholesale electric provider to municipally-owned utilities. REMCs, or Rural Electric Membership Cooperatives, can be either wholesale or retail providers of electricity to rural consumers. IMPA was created and is governed by its member utilities, while the member utilities are owned by the cities and towns. REMCs are owned by the consumers (members) in their service territories. 
What is the difference between IMPA and an investor-owned utility? 
IMPA is a wholesale electric provider to municipalities, and as such is a not-for-profit entity that exists to serve its members and their customers with low-cost, reliable power. Investor-owned utilities (IOUs) are for-profit entities that exist to make a profit for their shareholders. 
Why are some utilities regulated by the IURC and others not? 
Investor-owned utilities are required to be regulated by the Indiana Utility Regulatory Commission (IURC), which provides oversight of electric rates for consumer protection. Municipalities and REMCs can opt out of IURC regulation, because their rates can be overseen and regulated by their local government or board, and are subject to public hearings in the process. 
What is a combustion turbine peaking plant? 
Combustion turbine peaking plants are designed to provide power at times of high electric demand, such as during the very hot summer days or very cold winter nights.  IMPA owns seven combustion turbine units, located in Anderson, Richmond and Indianapolis.
What is IMPA doing to protect the environment? 
IMPA is working very hard with all its power supply partners to ensure that each of its generating facilities meets or exceeds Environmental Protection Agency (EPA) and Indiana Department of Environmental Management (IDEM) environmental standards. The Agency has implemented a variety of environmental technologies at all of its plants to reduce pollutant emissions to below the levels set forth by the government.  In addition, two of IMPA's jointly owned facilities – Gibson Station and Trimble County Station – as well as IMPA's combustion turbine stations are home to many species of wildlife, including several which are endangered. Several IMPA members also participate in environmental programs throughout their communities, including promoting the planting of electric-system-friendly trees and shrubs.
