In the early 1980s the group joined a vast coalition organized against the Zimmer Nuclear Power plant in Moscow, Ohio. Most groups in the coalition cited safety concerns and project mismanagement, but OPIC highlighted injustice to consumers who were paying Construction Work in Progress (CWIP) fees for a plant from which they had used no energy. By 1984, the Cincinnati Gas & Electric Company announced it would convert Zimmer to burn coal, instead of running the risk the plant would fail to secure a federal operating license after numerous cost overruns.
