Interconnection Agreements Wheatland Overview Interconnection Agreements Interconnected to two 345 kV lines. The plant has an interconnect agreement with both Cinergy Services Inc. (“Cinergy”), and Indianapolis Power & Light (“IPL”). With the dual interconnect, the plant has the option of dispatching into the Cinergy or IPL systems Both Cinergy and IPL allow scheduling of energy into and out of each control area, giving the Wheatland Plant the option of generating power or filling the scheduled energy delivery from the market when market economics warrant. This enables playing day ahead vs intra-day hourly market to maximize optionality This added flexibility ensures that the plant is reserved for operation only during periods of economic dispatch

Gas Supply & Transportation Wheatland Overview Gas Supply & Transportation Permitted to use natural gas as its fuel source Interconnected to Midwestern Gas Transmission Company (“Midwestern Gas”), a natural gas pipeline system owned by Tennessee Gas Pipeline Company The term of the interruptible gas transportation agreement and associated transportation rate began on April 1, 2000, continues through March 31, 2008 and will continue on a month-to-month basis until terminated upon thirty days notice by either party Gas can be purchased at Chicago city-gate hub or from Gulf Coast
