Where:
CO2e = Annual CO2 equivalent mass emissions from the unspecified electricity deliveries at each point of receipt identified (MT of CO2e).
MWh = Megawatt-hours of unspecified electricity deliveries at each point of receipt identified.
EFunsp = Default emission factor for unspecified electricity imports.
EFunsp = 0.428 MT of CO2e/MWh TL = Transmission loss correction factor.
TL = 1.02 to account for transmission losses between the busbar and measurement at the first point of receipt in California.
CO2e = MWh x TL x EFsp
Where:
CO2e = Annual CO2 equivalent mass emissions from the specified electricity deliveries from each facility or unit claimed (MT of CO2e).
MWh = Megawatt-hours of specified electricity deliveries from each facility or unit claimed.
EFsp = Facility-specific or unit-specific emission factor published on the ARB website and calculated using total emissions and transactions data as described below. The emission factor is based on data from the year prior to the reporting year.
EFsp = 0 MT of CO2e for facilities below the GHG emissions compliance threshold for delivered electricity pursuant to the cap-and-trade regulation during the first compliance period.
TL = Transmission loss correction factor.
TL = 1.02 to account for transmission losses associated with generation outside of a California balancing authority.
TL = 1.0 if the reporting entity provides documentation that demonstrates to the satisfaction of a verifier and ARB that transmission losses (1) have been accounted for, (2) are supported by a California balancing authority, or (3) are compensated by using electricity sourced from within California.
The Executive Officer shall calculate facility-specific or unit-specific emission factors and publish them on the ARB website using the following equation:
EFsp = Esp /EG
Where:
Esp = CO2e emissions for a specified facility or unit for the report year (MT of CO2e).
EG = Net generation from a specified facility or unit for the report year shall be based on data reported to the Energy Information Administration (EIA).
To register a specified unit(s) source of power pursuant to section 95111(g)(1), the reporting entity must provide to ARB unit level GHG emissions consistent with the data source requirements of this section and net generation data as reported to the EIA, along with contracts for delivery of power from the specified unit(s) to the reporting entity, and proof of direct delivery of the power by the reporting entity as an import to California.
Esp = 0.001 x £(Q x EF)
Where:
0.001 = conversion factor kg to MT
Q = Heat of combustion for each specified fuel type from the specified facility or unit for the report year (MMBtu). For cogeneration, Q is the quantity of fuel allocated to electricity generation consistent with EIA reporting. For geothermal electricity, Q is the steam data reported to EIA (MMBtu).
EF = CO2e emission factor for the specified fuel type as required by this article (kg CO2e /MMBtu). For geothermal electricity, EF is the estimated CO2 emission factor published by EIA.
Sum of Lesser of MWh = £HMsp min(MGsp*Ssp, TGsp)

ARB will assign the system emission factors for all asset-controlling suppliers based on a previously verified GHG report submitted to ARB pursuant to section 95111(f). The supplier-specific system emission factor is calculated annually by ARB. The calculation is derived from data contained in annual reports submitted pursuant to section 95111(f) that have received a positive or qualified positive verification statement. The emission factor is based on data from two years prior to the reporting year.
TL = Transmission loss correction factor.

The Executive Officer shall calculate the system emission factor for asset-controlling suppliers using the following equations:
EFACE = Sum of System Emissions MT of CO2e / Sum of System MWh
Sum of System Emissions, MT of CO2e = £Easp + £(PEsp* EFsp) + £(PEunsp* EFunsp) - £(SEsp* EFsp)
Sum of System MWh = £EGasp + £PEsp + £PEunsp - £SEsp
Where:
£Easp = Emissions from Owned Facilities. Sum of CO2e emissions from each specified facility/unit in the asset-controlling supplier's fleet, consistent with section 95111(b)(2) (MT of CO2e).
£EGasp = Net Generation from Owned Facilities. Sum of net generation for each specified facility/unit in the asset-controlling supplier's fleet for the data year as reported to ARB under this article (MWh).

SEsp = Electricity Sold from Specified Sources. Amount of wholesale electricity sold from specified sources by the asset-controlling supplier for the data year as reported to ARB under this article (MWh).
EFsp = CO2e emission factor as defined for each specified facility or unit calculated consistent with section 95111(b)(2) (MT CO2e/MWh).
EFunsp = Default emission factor for unspecified sources calculated consistent with section 95111(b)(1) (MT CO2e/MWh).
CO2e = (MWhR x TLR - MWhWSP-CA - EGCA) x EFMJRP + MWWSP-notCA x TLWSP x EFunsp - CO2elinked
Where:
CO2e = Annual CO2e mass emissions of imported electricity (MT of CO2e).
MWhR = Total electricity procured by multi-jurisdictional retail provider to serve its retail customers in California, reported as retail sales for California service territory, MWh.
MWhWSP-CA = Wholesale electricity procured in California by multi-jurisdictional retail provider to serve its retail customers in California, as determined by the first point of receipt on a NERC e-Tag and pursuant to a cost allocation methodology approved by the California Public Utilities Commission (CPUC) and the utility regulatory commission of at least one additional state in which the multi-jurisdictional retail provider provides retail electric service, MWh.

To apply for asset-controlling supplier designation, the applicant must:
"I certify under penalty of perjury under the laws of the State of California that I am duly authorized by [name of entity] to sign this attestation on behalf of [name of entity], that [name of entity] meets the definition of an asset-controlling supplier as specified in section 95102(a) of the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions, title 17, California Code of Regulations, section 95100 et seq., and that the information submitted herein is true, accurate, and complete." Asset-controlling suppliers must annually adhere to all reporting and verification requirements of this article, or be removed from asset-controlling supplier designation. Asset-controlling suppliers will also lose their designation if they receive an adverse verification statement, but may reapply in the following year for re-designation.
Each reporting entity claiming specified facilities or units for imported or exported electricity must register its anticipated specified sources with ARB pursuant to subsection 95111(g)(1) by February 1 following each data year to obtain associated emission factors calculated by ARB for use in the emissions data report required to be submitted by June 1 of the same year. If an operator fails to register a specified source by the June 1 reporting deadline specified in section 95103(e), the operator must use the emission factor provided by ARB for a specified facility or unit in the emissions data report required to be submitted by June 1 of the same year. Each reporting entity claiming specified facilities or units for imported or exported electricity must also meet requirements pursuant to subsection 95111(g)(2)-(5) in the emissions data report.
