Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(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:
FCNEMy+1 = CSC ER y-1
						  *(HR - HRO y-1)/HR
Where:
FCNEM = Fuel cell net energy metering GHG emission
						  standard
FCNEMy+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 ERy-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 ERy-1" is calculated as
						  follows:
CSC
ERy-1 =
CEC
SAy-1 * 0.001 * 53.07
Where:
CEC SAy-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:
FCNEMy+2 =
						  FCNEMy+1
- 13.4
Where:
FCNEM = Fuel cell net energy metering GHG emission
						  standard
FCNEMy+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:
FCNEMy+3 =
						  FCNEMy+2
- 13.4
Where:
FCNEM = Fuel cell net energy metering GHG emission
						  standard
FCNEMy+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
						FCNEMy+1, as calculated per section
						95412(a)(1), is
						greater than FCNEMy, FCNEMy+1
						shall be calculated as follows:
FCNEMy+1 =
						  FCNEMy
- 13.4
Where:
FCNEM = Fuel cell net energy metering GHG emission
						  standard
FCNEMy+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
