Slide 2: What is a Neighborhood Substation?
What is a Neighborhood Substation? ► A substation is part of an electrical generation, transmission, and distribution system that allows us to use electricity. ► Substations transform voltage from high to low so that lower voltage electricity can be sent to homes and businesses to operate everything
Slide 3: Project Purpose and Need
Project Purpose and Need ► The substation is needed to serve increased commercial and residential demand. (The targeted load center for the Brantner Substation is centered along Colorado Blvd and 128th Ave) ► The new substation will also provide backup and electric load relief for Washington, Glenn,

Slide 5: Distribution of Electricity
Distribution of Electricity ► There are two major distribution utilities in your community: ►Xcel Energy/Public Service Company of Colorado and United Power ►Public Service Company of Colorado, an investor- owned utility has been providing electricity to customers since 1924 ►United Power, a member-
Slide 6: Distribution of Electricity
Distribution of Electricity ► Electric distribution service territories often are not contiguous and form a patchwork throughout much of the greater Denver metro area. ► Because of the location of high voltage transmission lines it is not uncommon to see another utilities’ facilities located within
Slide 7: Why a Substation Here?
Why a Substation Here? ► Assessment of Needs ►Increased Residential Load Growth Approximately 3% annually ►Location – Ability to provide backup to existing substations 7
Slide 8: Why a substation here?
Why a substation here? ► Equipment Limitation Factors ►Electric feeders should not be more than 3 miles to the load being served ►The distance to provide back-up to the existing substations should be as short as possible ►The physical location of the existing transmission line used to energize the n

Slide 10: Substation Siting Analysis
Substation Siting Analysis ► The Purpose, Need, and equipment/facilities limitations help to determine the Siting Study Area These factor into developing siting criteria, also referred to as Opportunities & Constraints Criteria The criteria is used as parameters for evaluating potential site loc
Slide 11: Substation Siting Analysis
Substation Siting Analysis ► A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographic information. ► GIS allows us to view, understand, question, interpret, and visualize volumes of data in many ways that
Slide 12: Substation Siting Analysis
Substation Siting Analysis Criteria Evaluated: ► Distribution feeder length ► Distance to the transmission line ► Road accessibility ► Land use ► Proximity to residences ► Proximity to oil/gas wells ► Areas around radio towers ► Surface waters ► Floodplains ► Sensitive wildlife habitat ► Sensitive p
