Clifty Creek held its official dedication, following completion of the six-unit station.
Clifty Creek installed selective catalytic reduction equipment to reduce nitrogen-oxide emissions.
The Department of Energy power agreement ended after DOE's cancellation notice; thereafter the station's generating capacity was made available to the sponsoring utilities under the Inter-Company Power Agreement.
Construction of two flue-gas desulfurization scrubbers began, with each scrubber designed to serve three generating units.
Scrubber construction was approximately 35 percent complete when work was suspended because of capital constraints associated with the economic downturn.
The OVEC-IKEC board voted to restart the Clifty Creek scrubber project; construction was expected to resume in May 2011.
