AGENDA TITLE: Engineering Services for 230 KV Interconnection Project Phase II ($75,020)
MEETING DATE: March 5, 1997
SUBMITTED BY: Electric Utility Director
RECOMMENDED ACTION: That the City Council adopt the attached resolution authorizing the City
Manager to enter a personal services contract with Power Engineers, Inc. for
the 230 KV Interconnection Project Phase 2 - Preliminary Engineering.
BACKGROUND: On November 6, 1996, the City Council authorized a 230 KV west
interconnection scoping study. The results of this study were given to each
councilmember at the February 19, 1997 council meeting. This scoping study
accomplished three things:
analyzed previous studies conducted by NCPA, Western and PG&E;
provided and reviewed cost estimates for various options;
made recommendations as to the steps the City should take to continue with this project.
Continuing the project into Phase 2 - Preliminary Engineering is recommended. This phase includes the
preliminary engineering, siting and routing tasks in order to provide the City with the analysis and drawings
necessary to start the detailed design and engineering phases. It also provides the necessary steps required for
the initial study under the California Environmental Quality Act (CEQA) which will determine the level of
environmental permitting required for the project. The Community Development Department will be the lead
agency for addressing CEQA activities.
FUNDING: NCPA Phase IIA Resource Development Fund
Estimated Cost: $75,020

Subject: 230kV Interconnection Project
Engineering Work Plan for Preliminary Engineering
Dear Alan:
As you requested, we have prepared a Work Plan describing the initial tasks required for the
230kV Interconnection Project. The Work Plan includes five tasks to accomplish the initial
project objectives.
Completion of these tasks, which include the preliminary engineering and the routing and siting
tasks, would provide the City with the information, analyses and drawings needed to start the
actual design and engineering phases. Also, the steps required for an Initial Study under CEQA,
which will determine the level of environmental permitting required for the project, are described
in Task 2.
The Work Pian is as follows:
TASK 1 SYSTEM STUDIES
Objective: To help the City determine the system configuration, new 60kV transmission line
size and tie locations and operating criteria for the system with the addition of the new 230kV
interconnection. The deliverables produced in this task will allow the engineering and design of
the new facilities to proceed and will outline the operational possibilities and constraints for the
new system.
Approach:
• Establish the new 60kV facility requirements and operational capabilities and limitations for
the new system.
Interconnection Analyses: Draft a letter for the City to forward to NCPA, PG&E and/or West-
ern requesting the desired additional load flow simulations for two scenarios: future system
loading beyond the loading limits used in previous studies, and conditions where the existing
60kV system and the new 60kV system are electrically interconnected. Also, request any revised
mitigation cost estimates for the cases already studied and new mitigation cost estimates for any
new cases to be studied. We will provide a technical review of the results and prepare a letter
report outlining our conclusions and recommendations for discussion and ultimate inclusion into
the Final Report.

60kV Transmission Analysis: In conjunction with the City, determine the desired normal and
emergency circuit loading capacity for the new 60kV interconnect transmission line(s) and the
possible locations and configurations for the 60kV ties to the existing system. Consider existing
City criteria, line construction impacts, relative losses, physical constraints and operational
flexibility in determining the desired conductor and system configuration. Forward a letter report
outlining the findings to the City for discussion and ultimate inclusion into the Final Report.
12kV Loop Feed Investigation: Using a WSCC database provided by PG&E, Western, NCPA
or one retrieved from the FERC Bulletin Board, add the elements to model the City's 60kV
transmission system including the 60-12kV distribution substations. In conjunction with the City,
select possible l2kV circuits that could be switched to connect one substation 12kV bus to
another l2kV substation bus under conditions when the 12kV buses are served from separate
transmission sources. Add a simplified model of each 12kV tie circuit to the system model to
simulate the looped connection. To simulate actual conditions, assume that the simplified 12kV
tie circuit would consist of no more than eight (8) line sections with loads distributed along the
line. Perform six (6) system configurations and load flow simulations to determine the opera-
tional constraints of looping the system through the 12kV distribution network. Prepare and for-
ward to the City for discussion and ultimate inclusion into the Final Report a letter report out-
lining the findings and recommendations for potential loop feeds within the l2kV system.
Deliverables:
• Draft Letter to Forward to NCPA, PG&E and/or Western
• Technical Review of Additional Interconnection Analyses
• Recommended 60kV Transmission Conductor Type and Size
• Recommended Tie Location(s) for the Connection of the New 60kV Line(s) to the Existing
System
• Summary of 12kV Loop Flow Results
Assumptions:
• NCPA, PG&E and/or Western will conduct the additional interconnect studies.
• Tie locations will be investigated in conjunction with the Task 2 efforts.
• The City will provide 12kV backbone feeder and loading information.
• The 12kV loop studies will be limited to six (6) load flow scenarios.

Objectives: To identify a feasible substation site and transmission line routes. To identify
existing land rights for transmission line alternative routes. To prepare an Initial Study to deter-
mine CEQA compliance requirements and predict probable environmental impacts.
Approach:
• Investigate the two substation sites under consideration. Determine the advantages and disad-
vantages of using either site.
• Define the licensing and permitting requirements for each substation site in conjunction with
engineering design and City preferences.
• Conduct a preliminary routing study to identify the feasible 230kV transmission intertie tap
configurations from the Western lines to the selected substation site and for the line routes to
connect the selected substation site to the City's 60kV system.
• Identify the land rights along the potential line routes.
• In order to determine the appropriate CEQA action required, prepare an Initial Study.
Substation Siting Study: Investigate the two substation sites under consideration near the STIG
site (Wastewater Lagoon and west side of transmission corridor). Determine the advantages and
disadvantages of each site. Identify the licensing and permitting requirements for each site and
potential environmental impacts associated with developing each site. Prepare a Technical
Memorandum documenting the findings of the study and incorporate final version into the Initial
Study Report.
