LGOP Power Generation Facilities

Local governments that burn fossil fuels, municipal solid waste, or other materials to produce electricity, heat, or steam must quantify the associated emissions as Scope 1 emissions.

The amount of GHGs emitted from combustion depends greatly on the quantity of the fuel and the carbon content of the fuel used. Additionally, the "oxidation" fraction of a particular fuel also influences emissions and must be accounted for. An oxidation fraction reflects an incomplete combustion process, to the extent that all the carbon contained in the fuel does not oxidize into CO2, but remains as ash or unburned carbon.

Power generation facilities use a number of stationary combustion technologies to generate, transmit, and distribute electricity, and to produce heat and/or steam. Chapter 8 of the LGOP provides guidance to quantify CO2 emissions from these stationary combustion sources through two different methodologies:

o    Measurement-Based Methodology (Chapter 8.1)
o    Fuel Use-Based Methodology (Chapter 8.2)

Other emission related to power generation facilities include:

o    Scope 2 emissions from transmission and distribution losses (Chapter 8.3)
o    Fugitive emissions (Chapter 8.4)

Emissions from non-fossil fuels such as biomass, landfill gas, and biofuels are counted separately from other power combustion emissions. For guidance on calculating these emissions refer to:

o    Calculating Emissions from Biofuels, Waste Fuels, and Biomass
