Methodology for Calculating Greenhouse Gas Emissions

(1)

A generating facility’s annual average electricity production in megawatt-hours (MWh) is the sum of the electricity available for all of the following:

(a)

Use onsite;

(b)

Use at a host site in a commercial or industrial process;

(c)

Sale; or

(d)

Transmission from the generating facility.

(2)

The greenhouse gases for cogeneration facilities must include the total usable energy output of the process and includes all greenhouse gases emitted by the facility in the production of both electrical and thermal energy.

(a)

A cogeneration facility’s annual average electricity production is the sum of the MWh of electricity produced and the useful thermal energy output expressed in MWh.

(b)

The useful thermal energy output must be converted into a MWh equivalent using the standard engineering conversion factor of 3.413 MMBtu per MWh (or 3,413 Btu per kWh).

(3)

In determining whether a generating facility complies with the emissions standard, the total emissions associated with producing energy at the generating facility must be included in determining the rate of emissions of greenhouse gases. The total emissions associated with producing electricity at the generating facility do not include emissions associated with transportation, fuel extraction or other life-cycle emissions associated with obtaining the fuel for the facility.
