American Public Power Association

The American Public Power Association (APPA) is the national trade association representing not-for-profit, community-owned electric utilities in the U.S. APPA organizes multiple conferences, summits, and events (e.g., National Conference & Public Power Expo, Legislative Rally, APPA Academy events) focused on electric utilities, grid reliability, operations, and related infrastructure. This makes it a strong match for "utilities conference" and related infrastructure/municipal utility topics but less directly aligned with non-electric public works sectors (water utilities, transportation, facilities management).
