Understanding Electric Utility Types
Investor-Owned Utilities (IOUs)
Private companies owned by shareholders, serving about 72% of US electricity customers. IOUs are regulated by state public utility commissions and typically serve large urban areas.
Electric Cooperatives
Non-profit utilities owned by the communities they serve. Co-ops typically serve rural areas — about 13% of customers but 56% of the nation's landmass.
Municipal Utilities
Public utilities owned by local governments, serving about 14% of customers. Often offer competitive rates since they're non-profit and can respond quickly to local needs.
Federal Power Agencies
Government-owned utilities that typically operate large hydroelectric facilities (e.g., TVA, Bonneville Power). Often provide wholesale power to other utilities.
