3. Marketer Reporting Protocol

Marketers shall comply with the reporting requirements in Subsections 3.1, 3.3, and 3.4. The other subsections in Section 3 describe how ARB attributes GHG emissions to each marketer.

Report all quantities of electricity generated, purchased, or sold in MWh, as measured at the busbar or, if busbar data is not available, at the first point of receipt or point of delivery for which the reporting entity has information. For purposes of this Protocol, quantities of electricity received under exchange agreements are considered purchases, and quantities of electricity delivered under exchange agreements are considered sales.

3.1 Imports

Exclude any transactions reported pursuant to Section 3.3.

Report all imports of electricity from specified sources with a final point of delivery in California that the reporting entity delivered to the first point of delivery in California, reported separately for each power plant supplying the power. Include the plant name and ARB plant identification code for each plant.

Report all imports of electricity from unspecified sources with a final point of delivery in California that the reporting entity delivered to the first point of delivery in California, reported separately for each region of origin (Northwest or Southwest) and, within each region, reported separately for each party supplying the power, including the reporting entity itself where applicable.

3.2 Calculation of Emissions from Imports

Emissions are calculated based on the quantities of electricity imported and the corresponding emission factors as described below.

For imports from specified sources that report under ARB's source-based reporting system, ARB retrieves the emissions for all GHGs and the generation data transmitted to ARB under the source-based reporting system, and calculates emission factors on that basis.

For imports from specified sources not reporting under ARB's source-based reporting system, ARB calculates emission factors using data from finalized reports under 40 CFR Part 75 or plant-level fuel consumption data from the Energy Information Administration if Part 75 data are not available.

For imports from unspecified sources for which ARB has certified supplier-based emission factors (developed pursuant to Section 4), ARB uses the certified supplier-based emission factor. For imports from all other unspecified sources, ARB uses the appropriate regional default emission factor.

3.3 Wheel-throughs

Report any electricity imported into California that terminates in a location outside of California, as measured at the first California point of delivery. Report these transactions aggregated separately for each counterparty supplying the power, and for each region of origin (Northwest or Southwest), These transactions must be verifiable via NERC Etags.

3.4 Exports

Exclude any transaction reported pursuant to Section 3.3.

Report all exports of electricity from specified sources that the reporting entity delivered to the first point of delivery outside California. Report totals separately for each power plant supplying the power. Include the plant name and ARB plant identification code for each plant.

Report all exports of electricity from unspecified sources that the reporting entity delivered to the first point of delivery outside California.

3.5 Calculation of Emissions from Exports

Emissions are calculated based on the quantities of electricity exported and the corresponding emission factors as described below.

For exports from specified sources that report under ARB's source-based reporting system, ARB retrieves the emissions for all GHGs and the net generation data transmitted to ARB under the source-based reporting system, and calculates an emission factor on that basis.

For exports from specified sources not reporting under ARB's source-based reporting system, ARB calculates emission factors using data from finalized reports under 40 CFR Part 75 or plant-level fuel consumption data from the Energy Information Administration if Part 75 data are not available.

For exports from unspecified sources for which ARB has certified supplier-based emission factors (developed pursuant to Section 4), ARB uses the certified supplier-based emission factor. For exports from all other unspecified sources, ARB uses the appropriate default emission factor.
