“Tool to calculate baseline, project and/or leakage emissions from electricity consumption”
SCOPE, APPLICABILITY AND PARAMETERS
This tool provides procedures to estimate the baseline, project and/or leakage emissions associated with the
consumption of electricity. The tool may, for example, be used in methodologies where auxiliary
electricity is consumed in the project and/or the baseline scenario. The tool can also be applied in
situations where electricity is only consumed in the baseline or in the project or as leakage source.
The tool provides several options to project participants. These options aim to provide flexibility to project
participants, while ensuring that the estimation of emission reductions is conservative. Some options
provide more rough estimates of the emission reductions and rely on conservative default values or
conservative simplifications, whereas other options provide more accurate estimates but require more
accurate project or country specific data.
Methodologies which refer to this tool should:
(a) Specify clearly which sources of project, baseline and leakage electricity consumption should be
calculated with this tool;
(b) Provide the necessary procedures, equations and monitoring provisions to determine the quantity of
electricity that is consumed by each identified source; and
(c) Provide the necessary procedures to determine the most likely baseline scenario for each source of
baseline electricity consumption.
The tool is only applicable if one out of the following three scenarios applies to the sources of electricity
Scenario A: Electricity consumption from the grid. The electricity is purchased from the grid only.
Either no captive power plant is installed at the site of electricity consumption or, if any on-
site captive power plant exits, it is not operating or it can physically not provide electricity to
