CO2e | = | MWh × TL × EFsp | (Eq. 124-1) |
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 ecology 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. |
| TL | = | Transmission loss correction factor. |
| TL | = | 1.02 to account for transmission losses associated with generation outside of a Washington state balancing authority. |
| TL | = | 1.0 if the reporting entity provides documentation that demonstrates to the satisfaction of a verifier and ecology that transmission losses have been accounted for, or are compensated by using electricity sourced from within Washington state. |
(A) Ecology shall calculate facility-specific or unit-specific emission factors and publish them on the ecology website using the following equation:
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). |
(B) To register a specified unit(s) source of power, the reporting entity must provide to ecology 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 Washington state.
(I) For specified facilities or units whose operators are subject to this chapter or whose owners or operators voluntarily report under this chapter, Esp shall be equal to the sum of CO2e emissions reported pursuant to this section.
(II) For specified facilities or units whose operators are not subject to reporting under this chapter or whose owners or operators do not voluntarily report under this chapter, but are subject to the U.S. EPA GHG Mandatory Reporting Regulation, Esp shall be based on GHG emissions reported to U.S. EPA pursuant to 40 C.F.R. Part 98. For GHG emissions reported to U.S. EPA pursuant to 40 C.F.R. Part 98, if it is not possible to isolate the emissions that are directly related to electricity production, ecology may calculate Esp based on EIA data. Emissions from combustion of biomass-derived fuels will be based on EIA data until such time the emissions are reported to U.S. EPA.
(III) For specified facilities or units whose operators are not subject to reporting under this chapter or whose owners or operators do not voluntarily report under this chapter, nor are subject to the U.S. EPA GHG Mandatory Reporting Regulation, Esp is calculated using heat of combustion data reported to the Energy Information Administration (EIA) as shown below.
Esp | = | 0.001 × Σ(Q x EF) | (Eq. 124-3) |
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 chapter (kg CO2e/MMBtu). For geothermal electricity, EF is the estimated CO2 emission factor published by EIA. |
(IV) Facilities or units will be assigned an emission factor by the ecology based on the type of fuel combusted or the technology used when a U.S. EPA GHG Report or EIA fuel consumption report is not available, including new facilities and facilities located outside the U.S.
(V) Meter data requirement. For verification purposes, electric power entities shall retain meter generation data to document that the power claimed by the reporting entity was generated by the facility or unit at the time the power was directly delivered.
(VI) A lesser of analysis is applicable to imports from specified sources for which ecology has calculated an emission factor of zero, and for imports from Washington renewable portfolio standard (RPS) eligible resources, excluding the following: Dynamically tagged power deliveries; nuclear power; asset controlling supplier power; and imports from hydroelectric facilities for which an entity's share of metered output on an hourly basis is not established by power contract. A lesser of analysis is required pursuant to the following equation:
Sum of Lesser of MWh | = | ΣHMsp min (MGsp*Ssp, TGsp) | (Eq. 124-4) |
Where: |
| ΣHMsp | = | Sum of the Hourly Minimum of MGsp and TGsp (MWh). |
| MGsp | = | Metered facility or unit net generation (MWh). |
| Ssp | = | Entity's share of metered output, if applicable. |
| TGsp | = | Tagged or transmitted energy at the transmission or subtransmission level imported to Washington (MWh). |
(iii) Calculating GHG emissions of imported electricity supplied by asset-controlling suppliers. Based on annual reports submitted to ecology pursuant to WAC
173-441-070(3), ecology will calculate and publish on the ecology website the system emission factor for all asset-controlling suppliers recognized by the ecology. The reporting entity must calculate emissions for electricity supplied using the following equation:
CO2e | = | MWh × TL × EFacs | (Eq. 124-5) |
Where: |
| CO2 | = | Annual CO2 equivalent mass emissions from the specified electricity deliveries from ecology-recognized asset-controlling suppliers (MT of CO2e). |
| MWh | = | Megawatt-hours of specified electricity deliveries. |
| EFACS | = | Asset-Controlling Supplier system emission factor published on the ecology website (MT CO 2e/MWh). Ecology will assign the system emission factors for all asset-controlling suppliers based on a previously verified GHG report submitted to ecology pursuant to WAC 173-441-070(3). The supplier-specific system emission factor is calculated annually by ecology. The calculation is derived from data contained in annual reports submitted 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. |
| TL | = | 1.02 when deliveries are not reported as measured at a first point of receipt located within the balancing authority area of the asset-controlling supplier. |
| TL | = | 1.0 when deliveries are reported as measured at a first point of receipt located within the balancing authority area of the asset-controlling supplier. |
Ecology must calculate the system emission factor for asset-controlling suppliers using the following equations:
EFACS | = | Sum of System Emissions MT of CO2e/Sum of System MWh | (Eq. 124-6) |
Sum of System Emissions, MT of CO2e | = | ΣEasp + Σ(PEsp * EFsp) + Σ(PEunsp * EFunsp) - Σ(SEsp * EFsp) | (Eq. 124-7) |
Sum of System MWh | = | ΣEGasp + ΣPEsp + ΣPEunsp - ΣSEsp | (Eq. 124-8) |
Where: |
| ΣEasp | = | Emissions from owned facilities. Sum of CO2e emissions from each specified facility/unit in the asset-controlling supplier's fleet (MT of CO2e). |
