History
American Municipal Power, Inc. (AMP) was founded in 1971 when a group of municipally owned electric systems joined forces to strengthen wholesale market buying power, gain access to transmission and enhance advocacy efforts.
Originally called American Municipal Power-Ohio, Inc., AMP’s primary focus in its first 25 years was joint ownership of electric facilities, pooled buying power in energy markets and alternative means of generating, transmitting and distributing electric power and energy to benefit customer-owners. The organization also provided a forum for Members to come together on mutual aid, safety training, and other programs, as well as regulatory and policy matters.
Through the years, the organization has developed a variety of programs and services to meet Member needs. In 2009, in recognition of the expanded membership footprint, AMP-Ohio officially became AMP. AMP has grown to serve more than 130 Members across nine states.
AMP 50 Years

In 2021, AMP celebrated its 50th anniversary of serving Member electric systems: five decades of being Stronger Together.
In AMP’s first 50 years, it was proven time and again that municipal electric systems are stronger when they work together. Through the years, AMP and its Members have celebrated many key milestones that have strengthened public power.
Throughout its 50th anniversary year, AMP gathered more than two dozen interviews, videos, historical reference materials and photos to document AMP’s history and many of the organization’s achievements since its founding in 1971.
