When Ohio’s investor-owned utilities pushed to deregulate the electricity markets, Ohio Citizen Action helped write the “community choice” provision of the 1999 deregulation law, which allowed local governments to aggregate residents into a single buying group that could solicit competitive bids and save residents money. Later the organization advocated for aggregated communities to use their power to solicit bids for renewable energy to meet their electricity needs. In 2012, Ohio Citizen Action campaigned for the City of Cincinnati to aggregate and contract for renewable energy. At the time, Cincinnati was the largest U.S. city to do so.
