Cal. Code Regs. Tit. 17, § 95412 - Greenhouse Gas Emission Standards Methodology

(a) Beginning in 2022, and every three years thereafter until 2047, the Executive Officer shall calculate the annual greenhouse gas emission standards for the next three years and publish them on the California Air Resources Board (CARB) website using the process outlined in section 95412(a)(1)-(4). The calculation will be performed on the second Monday of November and published on the CARB website within five business days.

(1) Calculate the standard for the calendar year following the year in which the triennial update is occurring using the following equation:

FCNEM_y+1 = CSC ER _{y-1 *(HR - HRO y-1)/HR}

Where:

FCNEM = Fuel cell net energy metering GHG emission standard

FCNEM_y+1 = FCNEM GHG emission standard for year y+1 (kgCO₂e/MWh) rounded to the tenths place (00.0)

y = Calendar year in which the update is occurring CSC ER_y-1 = CEC GHG emission rate (kgCO₂e/MWh) for combined/simple cycle gas power plants for year y-1, or the most recent year that data is available

"HR" = Number of hours in a year (8,760 for years with 365 days)

"HR0y-1" = Hours the day-ahead market electricity price was at or below zero for year "y-1" or the most recent year that day-ahead market electricity price data are available from the California Independent System Operator Department of Market Monitoring Unit, published annually pursuant to the Code of Federal Regulations, title 18, section 35.28(g)(3)

"CSC ER_y-1" is calculated as follows:

CSC ER_y-1 = CEC SA_y-1 * 0.001 * 53.07

Where:

CEC SA_y-1 = State average natural gas-fired electric generation heat rate value (Btu/kWh), excluding cogeneration plants, for year y-1, or the most recent year that data are available from the California Energy Commission pursuant to California Code of Regulations, Title 20, Division 2, Chapter 3, Section 1304(a)

0.001 = Conversion factor Btu/kWh to million Btu (MMBtu)/MWh

53.07 = Conversion factor MMBtu/MWh to kgCO₂e/MWh

(2) Calculate the standard for the calendar year two years after the year in which the triennial update is occurring using the following equation:

FCNEM_y+2 = FCNEM_y+1 - 13.4

Where:

FCNEM = Fuel cell net energy metering GHG emission standard

FCNEM_y+2 = FCNEM GHG emission standard for year y+2 (kgCO₂e/MWh) rounded to the tenths place (00.0)

y = Calendar year in which the update is occurring

13.4 = Adjustment to reduce annual GHG emission standard by 13.4 kgCO₂e/MWh

(3) Calculate the standard for the calendar year three years after the year in which the triennial update is occurring using the following equation:

FCNEM_y+3 = FCNEM_y+2 - 13.4

Where:

FCNEM = Fuel cell net energy metering GHG emission standard

FCNEM_y+3 = FCNEM GHG emission standard for year y+3 (kgCO₂e/MWh) rounded to the tenths place (00.0)

y = Calendar year in which the update is occurring

13.4 = Adjustment to reduce annual GHG emission standard by 13.4 kgCO₂e/MWh

(4) If in any year FCNEM_y+1, as calculated per section 95412(a)(1), is greater than FCNEM_y, FCNEM_y+1 shall be calculated as follows:

FCNEM_y+1 = FCNEM_y - 13.4

Where:

FCNEM = Fuel cell net energy metering GHG emission standard

FCNEM_y+1 = FCNEM GHG emission standard for year y+1 (kgCO₂e/MWh) rounded to the tenths place (00.0)

y = Calendar year in which the update is occurring

13.4 = Adjustment to reduce annual GHG emission standard by 13.4 kgCO₂e/MWh
