♦ Category: Energy

IPCC: 1A1ai - Fuel Combustion Activities - Energy Industries - Main Activity Electricity and Heat Production - Electricity Generation
Sector: Electricity Generation (Imports) : Specified Imports : Nevada : Harry Allen Station (NV)

♦ Activity: Electricity generation - Primary fuel: Natural Gas

♦ Greenhouse gas: Methane ( CH4 )

► Year 2016 —

● Greenhouse gas emission estimate —

Amount: 0.447 tonne of CH4 Emitted (11.19 tonnes CO2 Eq.)
Basis: Calculation
Calculation: [Electricity Generation] * [CH4 emission factor]
Reference: CARB (2016). Technical support document on GHG inventory methodologies for the 2000-2014 inventory. See Discussion of emissions from electricity imports available at: https://ww3.arb.ca.gov/cc/inventory/pubs/reports/2000_2014/ghg_inventory_00-14_technical_support_document.pdf

● Activity level used in calculations —

Activity: Electricity generation = 63,165,540 kWh of Primary fuel: Natural Gas
Basis: Data
Reference: CARB (2021). Summary of 2008 to 2019 data from California's Greenhouse Gas Mandatory Reporting Program. Reported emissions are available at: https://ww2.arb.ca.gov/our-work/programs/mandatory-greenhouse-gas-emissions-reporting

● Parameters and Constants used in calculations —

Parameter: CH4 emission factor = 7.084E-03 g / kWh
