IMPA Combustion Turbines

 

IMPA has seven wholly-owned combustion turbines and associated facilities aggregating 419 MW.  The Combustion Turbines include two 41 MW units, placed in service in 1992 and one 85 MW unit placed in service in 2004 located in Anderson, Indiana; two 41 MW units, placed in service in 1992 located near Richmond, Indiana; and two 85 MW units, acquired by IMPA in 2004, located in Indianapolis, Indiana.  IMPA employees operate and maintain the combustion turbines located in Anderson and Richmond.  The Georgetown Plant is currently operated and maintained by Indianapolis Power & Light Company. 

The Anderson and Richmond Combustion Turbines operate primarily on natural gas, which is delivered under an interruptible transportation contract with Vectren.  This contract gives IMPA the option to obtain its own gas supplies with local distribution supplied by Vectren.  The Anderson and Richmond Combustion Turbines also maintain an inventory of No. 2 fuel oil as an alternative fuel in the event of interruptions in natural gas supply, or as an economic option.  The Georgetown Plant operates solely on natural gas, which is delivered pursuant to a capacity reservation and gas transportation agreement with Citizens Gas.  Natural gas used to operate the Combustion Turbines is purchased at market prices.
