The Indiana Department of Environmental Management on Sept. 13 issued the final Title IV acid rain permit for the gas-fired St. Joseph Energy Center LLC power project in St. Joseph County, Ind.
The permit covers four natural gas-fired combined cycle combustion turbines, identified as units CCCT1, CCCT2, CCCT3, and CCCT4, permitted in 2012, each with a combustion turbine equipped with dry low NOx burners, natural gas fired duct burners, and a heat recovery steam generator identified as HRSG1, HRSG2, HRSG3, and HRSG4. The nominal heat input for each CCCT is 2,300 MMBtu/hr (higher heating value (HHV)). The combined nominal power output is 1,350 MW.
On July 23, the department’s Office of Air Quality (OAQ) had a notice published in the South Bend Tribune in South Bend, Ind., stating that St. Joseph Energy Center had applied for a Title IV permit.
The department in December 2012 had issued a prevention of significant deterioration air permit to St. Joseph Energy Center for this same plant.
The Indiana Utility Regulatory Commission in February approved this project. St. Joseph Energy Center LLC is a subsidiary of an investment fund managed by ElF Management LLC, which was founded in 1987 as the first investment manager dedicated exclusively to the independent power and electric utility industry. Funds managed by ElF Management currently own and operate a number of power plants.
