to the north of the Project site. Currently, approximately 300 dwelling units could be served
by the existing overhead facilities associated with the Gorman Substation before a utility
upgrade would be required (BJ Palmer 2015).

Project Design Features

See the Centennial Specific Plan’s Appendix 1-B, Green Development Program, and summary
of corresponding Project Design Features in Section 5.21, Climate Change.

Threshold Criteria

The following criterion from the County of Los Angeles Environmental Checklist is used to
establish the threshold in order to determine the potential for significance. The Project
would result in a significant impact to electrical facilities and services if it would:

Threshold 20-1 Create energy utility (electricity, natural gas, propane) system capacity
problems, or result in the construction of new energy facilities or
expansion of existing facilities, the construction of which could cause
significant environmental effects.

Environmental Impacts

Threshold 20-1 Would the project create electrical system capacity problems, or
result in the construction of new energy facilities or expansion of
existing facilities, the construction of which could cause
significant environmental effects?

On-Site Impacts

The Project would place new demands on electrical service provided by SCE. Specifically, the
Project would result in an increase in the amount of electricity consumed on the site for
lighting and other uses, and it will create a need for new delivery infrastructure. The physical
environmental impacts related to the implementation of necessary utility infrastructure are
addressed as part of the Project analyzed throughout this EIR.

Electrical Demand

Project construction would involve limited electricity demands for equipment such as
temporary lighting fixtures and tools.

During operations, SCE estimates that buildout of all proposed land uses in the Project over
a 20-year horizon would generate a peak increase in electricity demand of approximately
165 MW1 at buildout (as shown in Table 5.20-1, Southern California Edison Estimate of the
Centennial Peak Electrical Demand). The peak demand, rather than the total annual demand,
is based on the type and quantity of land uses on the Project site which SCE determined
would collectively generate the highest demand (i.e., peak) for electricity at one time (rather
than the average demand of all types and quantities of the proposed land uses). The purpose

1 A megawatt (MW) is one million watts
