The Louisiana Energy and Power Authority (LEPA) is a joint-action agency established in 1979 to provide firm, stable sources of electricity to its member communities. LEPA operates across 17 Louisiana cities and towns, each maintaining its independent municipal power system.

LEPA works to ensure member communities receive electricity at the lowest possible cost. By allowing optional participation in the system operation, member cities can realize significant power cost reductions while maintaining control over their municipal systems. This joint-action arrangement is recognized as the best approach for energy management in Louisiana and other states.
