Description: The William H. Zimmer Power Station, located near Moscow, Ohio, was originally intended to be a boiling water reactor type of nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. Today, the plant is generates 1400 gross MWe and 1300 net MWe. Zimmer Power Station is the largest single-unit power facility in the United States and is majority-owned by Duke Energy. Another very unusual fact about this plant is that Little Indian Creek flows into the Ohio River through the plant. The creek continues to run the way it did, but has several environmental features to prevent pollution of Little Indian Creek from the plant.
