The Independent Energy Producers of Maine (IEPM) is a not-for-profit association of renewable power producers, suppliers of goods and services to those producers, and other supporters of this industry. IEPM power producer members generate electricity in a sustainable manner from hydro, biomass, wind, and waste to energy. Located in Augusta, Maine, the IEPM represents the renewable power industry at the State Legislature and before the Maine Public Utilities Commission. In 1999 the IEPM joined with its sister associations from other New England states to form the New England Renewable Power Producers Association. NERPPA represents the renewable power industry at the New England Power Pool (NEPOOL), and before the Federal Energy Regulatory Commission (FERC).
