GENERAL
The proposed Southline Project would redevelop an approximately 26.5-acre industrial site in the City of
South San Francisco (City), CA through implementation of the proposed Southline Specific Plan, which
would allow for buildout of a transit-oriented office/research and development (R&D) campus with a
maximum anticipated building area of 2,800,000 square feet, in addition to below grade and above grade
parking structures. The proposed project would also construct off-site transportation, circulation, and
infrastructure improvements at several locations outside the Specific Plan area, totaling approximately 6.4
acres (collectively, with implementation of the Specific Plan, the “Southline Project” or “project”.) The
EIR prepared for the Southline Project analyzes two reasonably foreseeable buildout scenarios: the Office
Scenario and the Life Sciences Scenario. The Office Scenario assumes development of office uses up to
seven stories tall and the four-story amenities building (Building 2), for a total of 2,800,000 square feet;
the Life Science scenario assumes development of R&D uses, including laboratory and office spaces, up
to six stories tall and the four-story amenities building (Building 2), for a total of 2,025,050 square
feet. Phase 1 of the Southline Project contemplates two office buildings totaling approximately 612,715
SF and one 88,200 square foot amenities building which includes 16,400 square feet of public retail and
dining spaces and 71,800 of tenant-serving amenity spaces. The analysis provided estimates the total
electric demand based on historical utility data. Coincidentally, the maximum demand for the two options
appear to be about the same, taking into account the differences in useable square footage, and recent
evaluation of office space versus life science space electric demands.
The development site is bordered by S. Maple Avenue to the west, Tanforan Avenue to the south and
Dollar and Linden Avenues to the east. Southline Avenue is proposed to bisect the project site into
northern and southern areas.
Scope of this narrative is to describe existing and proposed electric utility requirements for the project,
including load projections as relevant to existing and required capacity to serve the project. This data is
necessary for utility engagement to assure capacity when needed. Also included in this narrative is a
description of peripheral improvements necessary to serve the project, including overhead to underground
utility system conversions as required for street improvements, and or project conditions of approval.
Service delivery concept is discussed and illustrated as well.
Gas distribution has not been analyzed within this scope. Trending is all electric use for major
commercial campuses. Additional analysis may be provided if the project becomes all electric.
ELECTRIC UTILITY DISTRIBUTION SYSTEM
Existing Electric Distribution System
PG&E is the existing electric service provider in the greater project area. PG&E electric distribution
facilities in the greater subject project area are served from the East Grand Substation. East Grand
Substation serves the greater South San Francisco area. The station has 115kV overhead feeds and is
equipped with four (4) three-phase 115/12kV transformer banks. There are seventeen (17) 12kV
distribution feeders emanating from the station providing electric distribution to the greater South San
Francisco area.
Local electric distribution utilities in the project area consist of 600A and 200A 12kV underground
and overhead distribution lines and secondary systems of below 600V. Specifically within project site
are PG&E 12kV overhead and underground radial distribution and secondary service systems that
will require removal before demolition and initial grading and or geotechnical efforts. PG&E
applications for these removals and quitclaiming of any identified PG&E easements should be made
8-10 months before the site must be cleared.
12kV distribution facilities on the site periphery include overhead facilities on the project side of S.
Maple Avenue, Tanforan Avenue, and Dollar Avenue. As an element of project conditions of
approval, undergrounding of all utilities on the project side periphery is anticipated. The overhead to
underground conversions will be pursuant to the California Public Utilities Commission Rule 20
tariff. Requirements for undergrounding of existing overhead lines are identified in attached exhibits,
and subsequent sections of this narrative. Timelines for undergrounding existing overhead PG&E
facilities is 12-24 months.
Existing Electric Utility Demand
Based on the provided limits of the project site, about 845kVA of transformer nameplate capacity will be
removed to accommodate development. This would equate to about 500kVA of demand or capacity that
will be available, and potentially offset the proposed and anticipated electric demand. Again, the removal
of these facilities the quitclaim of their associated easements will be necessary for development of the
site.
Proposed Electric Distribution System
The following describes the proposed undergrounding of peripheral electric distribution facilities,
including the undergrounding per C.P.U.C. Rule 20 tariff, and new line extensions to serve load based on
applicable C.P.U.C. Rule 15 and 16 tariffs. The local PG&E electric distribution system will most likely
require reinforcement for the anticipated project electric demand. PG&E planning engineers will review
the loads and timelines for project requirements and develop a plan to transfer load and or provide
additional distribution facilities to serve the project. Rule 20 undergrounding projects previously
mentioned above will include substructure work to accommodate the required additional capacity if
necessary. Specifically, additional conduits and cables to provide additional capacity would be included
in the underground work. Please note that the utility is responsible for the cost of any system upgrades
off-site in excess of existing local capacity to accommodate the projected loads to the point of new project
line extension, as long as the loads are not atypical. This means that the loads are realistic for the type of
use proposed. Atypical load projections may result in utility deficiency billing for revenue based
allowances in excess of load realized; therefore reasonable load forecasts are paramount.
The undergrounding of the peripheral existing overhead systems will require trench and excavation for
utility vaults, and the installation of conduits and boxes. The addition of cable and devices will create
system continuity. The proposed underground system will be will be equivalent to the overhead system
per tariff. Any improvements related to capacity or for utility convenience would be defined as
“betterment,” and the costs borne by the utility. The undergrounding of the system should include
elements of the new service facilities for the subject project, and those facilities should be accounted for
in the Rule 15 and 16 tariffs. Undergrounding of existing customers on Tanforan Avenue will be
required. It is the applicant’s obligation to underground services along the underground route per PG&E
interpretation of the tariff. This precludes the installation of service poles on the opposite side of the street
where they do not already exist. The applicant is encouraged to work with PG&E for beneficial
interpretation of the tariff to allow service poles. PG&E’s latest tariff interpretation of not allowing
service poles is both inconsistent with past interpretations, and unfairly burdens the development
community with open ended cost. Also, for the Rule 20 undergrounding to proceed per PG&E, written
permission from each customer to be undergrounded must be provided to the utility. Undergrounding to a
customer’s premises is costly and difficult; strategies for customer contact and negotiation of
underground service arrangement are encouraged. Budgetary and illustrative exhibits for the necessary
Rule 20 work and costs are included in this study.
Again, noteworthy is the communication of realistic anticipated loads to the utility early in the
development process, so that any system improvement work may be identified, designed and constructed
to meet occupancy dates as required.
Again, electric distribution facilities of adequate capacity that provide interconnection on the periphery or
limits of the project should be provided by the utility at no cost to the developer. This includes design,
construction and land rights procurement for any electric utility distribution improvements off-site
providing additional capacity to the project.
The electric distribution system on-site should consist of 600A 12kV main line feeder continuity, and
200A, 12kV protected radial tap lines feeding pad mounted transformers, or medium voltage switchgear
at each building location as preferred. Peripheral pad mounted or subsurface distribution equipment such
as switches, interrupters and street lighting transformers would be placed in franchised areas or where
adequate land rights exist for the equipment and required working space. Underground apparatus may be
provided where the utility allows; these facilities would be subject to special facilities charges as
described in the appropriate section of the Rule 2 tariff. Exhibits illustrating these equipment
requirements are included in the study.
Service facilities, specifically pad mounted transformers will be located at grade where adequate space
exists for equipment and working space, or in at grade transformer rooms that comply with the latest
revision of the “PG&E Greenbook.” PG&E may allow the use of UCD (subsurface) transformers, where
load requirements do not exceed standard available transformer capacity. It should be noted that any
facilities requested that are beyond what the utilities define as “standard” are subject to special facilities
charges (cost of ownership to perpetuity). Switchboard/meter locations, access and mechanical protection
must be in accordance with the latest revision of the “PG&E Greenbook.” Geotechnical efforts should
include any requirements for settlement vaults based on available data.
To accommodate proposed grading operations existing PG&E facilities will be impacted. Removal of
PG&E 12kV facilities to accommodate environmental remediation and grading will be required
Land rights for electric distribution utility elements, such as utility corridors, public utility easements and
other rights for utility ingress and egress will be necessary where distribution utilities are required on-site.
“Distribution facilities,” by definition are facilities serving more than one customer, therefore land rights
may be necessary on-site where systems serve more than one customer (building). Parcelization may
require distribution or service land rights if such a system crosses third party properties on route to their
terminus.
Proposed electric distribution systems are planned to be an element of a joint or common trench system
which would include gas, phone, cable TV, and streetlight facilities as applicable.
Planning Exhibit ‘A’ illustrates PG&E existing 12kV primary distribution system, required removals for
site clearing and removals for Rule 20 undergrounding.
Planning Exhibit ‘B’ illustrates PG&E conceptual 12kV primary distribution system arrangement for
peripheral Rule 20 work, and new service line extensions to serve the project.
Costs including reimbursable amounts and refunds associated with the PG&E new business Rule 15/16
would be based on the appropriate tariffs. Costs for the Rule 20 undergrounding will be borne by the
applicant requesting the undergrounding. The cost of trenching, conduits and vaults/boxes is solely the
responsibility of the developer for all tariff applications.
Proposed Electric Utility Demand
The total cumulative peak coincident power demand (design) for the subject project at full build out is
about 11 MVA (design). This value is based on interpretation of general use data provided and historical
PG&E load data for the project specific climate zone. Two (2) PG&E 12kV distribution feeders are
suggested for reliability if the projected peak demand is realized. Load will be phased in over a period of
about 6 years as the project builds out. See Exhibit ‘B’ for breakdown of electric demands over time.
Redundancy and Reliability
The proposed PG&E distribution arrangements illustrated in this narrative are based on existing and
published electric utility design and planning standards, and typical sound utility practice. Actual
distribution system arrangement including source and level of redundancy is to be determined by the
serving utility. There are two East Grand Sub 12kV circuits in the vicinity of the project. Any project
electric reliability criteria in excess of typical utility provisions should be defined, and vetted through the
utility planning department before design and specification of proposed facilities.
The project’s proximity to the East Grand Substation and the undergrounding of peripheral facilities
provide a reasonable level of reliability.
Renewables and Electric Vehicle Charging
Conceptual renewable energy production or distributed generation planning is not available at this time.
Electric vehicle charging load data is based on recently developed criteria, as follows; commercial
charging is based on the following assumptions 15% of total parking spaces, utilizing Level II chargers
with a 45% demand factor. This load criteria to be confirmed and updated as requirements and market
determines.
The renewable power production portfolio is to be determined. Installation and interconnection of any
generation facilities are governed by utility rules and policy. Type, size, configuration and location of all
generation facilities must be compliant with the latest rules for generation interconnection, and must be
developed and coordinated in collaboration with the utility to assure compliance with utility rules, and to
assure integration and satisfactory performance with the existing utility systems.
Study Conclusions
As discussed above, a project of this magnitude will most likely require PG&E planning and analysis to
confirm system capacities as the project builds out. Ongoing PG&E communication regarding loads, type
of use and scheduled buildout are primary considerations of the project. Secondarily, Rule 20
undergrounding of existing peripheral systems will be required. Costs should be evaluated, as well as
impact on project schedule based on the cooperation of local residents impacted by the undergrounding.
Removals of existing facilities in a timely manner is necessary for required on-site work and should be
scheduled well ahead of dates required to clear the site. Where facility relocations or undergrounding is
required, facility locating is recommended. The civil utility bases should identify existing facility
placement where necessary to accommodate all utility work required.
