CO 2 Emission Standards for Affected Stationary Combustion Turbines That Commenced Construction After January 8, 2014, and Reconstruction After June 18, 2014 (Net Energy Output-Based Standards Applicable as Approved by the Administrator)

[Note: Numerical values of 1,000 or greater have a minimum of 3 significant figures and numerical values of less than 1,000 have a minimum of 2 significant figures] Affected EGU CO 2 Emission standard Newly constructed or reconstructed stationary combustion turbine that supplies more than its design efficiency or 50 percent, whichever is less, times its potential electric output as net-electric sales on both a 12-operating month and a 3-year rolling average basis and combusts more than 90% natural gas on a heat input basis on a 12-operating-month rolling average basis 450 kg CO 2 /MWh (1,000 lb CO 2 /MWh) of gross energy output; or 470 kg CO 2 /MWh (1,030 lb CO 2 /MWh) of net energy output. Newly constructed or reconstructed stationary combustion turbine that supplies its design efficiency or 50 percent, whichever is less, times its potential electric output or less as net-electric sales on either a 12-operating month or a 3-year rolling average basis and combusts more than 90% natural gas on a heat input basis on a 12-operating-month rolling average basis] 50 kg CO 2 /GJ (120 lb CO 2 /MMBtu) of heat input. Newly constructed and reconstructed stationary combustion turbine that combusts 90% or less natural gas on a heat input basis on a 12-operating-month rolling average basis Between 50 to 69 kg CO 2 /GJ (120 to 160 lb CO 2 /MMBtu) of heat input as determined by the procedures in § 60.5525.
