The Indiana Department of Environmental Management had in December 2012 issued air permits for the project, including a prevention of significant deterioration permit. The permits had a routine 18-month deadline for the project to go into construction or the permits would lapse, according to GenerationHub.
In February, the developer asked for the 18-month deadline extension, citing delays for the project like reconfiguration of turbine layout design and in working out grid interconnection agreements. The agency on April 1 approved the extended deadline.
The 2012 permits covered four natural gas-fired combined cycle combustion turbines and four heat recovery steam generators.
The combined nominal power output would be 1,350 MW under that permit. The PJM Interconnection website shows this project working its way through the interconnection process under a reduced size of 675 MW.
