RE:
Recommendations from Energy Subcomrnittee regarding April 21 2009 Agenda
Item 8
__ __ 1
Acting as the Energy Subcommittee, we have held several meetings over the past few months in
which we have discussed various aspects of energy-related issues in Chula Vista. \\lith the issuance
of the City's SolarRFP and rhe process on the Chula Vista Encrgy Upgrade Pwject (C\lEUP) near
completion, we believc that now IS the time to regroup and move forward in a direCtlon designed to
accomphsh our unanimous Council goal to remove the South Bay Power Plant from our 13ayfwnt.
Thcre are a number of reasons the council should takc action soon. Firsr, San Diego Gas and
Electric is expected to issue a new Request for Offers (RFO) for gencratlon, the results of which
could be a key facwr in removal of the IUvIR or resomce adequacy design~tions from the power
plant.
Second, the Regional Water Quality Contwl Board will consider the renewal of the plant's Natlonal
Pollutant Dischargc Elinlll1ation System (NPDES) pernllt in the next few months. The current
NPDES perrnit expires in November of this year and the plant cannot operate if thc permit is not
renewed. Third, the Califorma Independent System Operator's (CAISO) annual Relwbility l'vlust
Run (RMR) rcview period is August to November.
We also understand that there may be negotiations by the Port District to extend the leases of the
power plant and the substatIon beyond their current lease terms. Our city needs to bc involved and
active with any future action on the part of the Port DistrIct in these negotiatlons and provide lllput
to our Port Commissioner.
\X!hile the CVEUP process was difficult for our community, one positive aspect is that many of our
Federal, state, and local leaders and community members have become aware of and very involved
in our collective effon to remove the South Bay Power Plant:. \V'hile we have sometimes had
Item 8, page I of 2
'-
-,
different ideas of how best to do this, the city council now has an opportumty to move this effort
forward.
Another positive aspect of this process was the identification of potentIal public and priv:1tcly
owned alternative sites within Clty limits that could meet basIc conditions to locate a peaker power
plant or other type of generation. \Y./e also know more aGout the size of the 'reliability gap' and how
best to address it.
All of these issues have been discussed 111 our various subconunittee meetings. To harness the
momentum and the interest of all parties around South Bay energy issues and to enSUl:e that the city
is well positioned to take assertive action on upcoming decisions that will be made, we recommend
that the full council take the following direction on Tuesday, April 21,2009
. Direct staff to assemble specific informatl<:m on publicly and privately owned sites within the
Clty of Chuh Vista that are at least four acres in size, at least '\ ,000 feet from sensitive
receptors, and zoned for general industrial uses.
. Task the Energy Subcommittee to convene a Blue Ribbon Comnuttee uf Chula Vista and
other Federal, State and Local elected leaders and stakeholders to work collectively with
CAISO and other state energy agencies to secure specific commitments for projects and
timelines resulting in the removal of IU'iIR from South Bay Power Plan.
. Direct staff to assemble necessary inform~ltion on the upcoming renewal of the NPDES
permit for the South Bay Power Plant and to communicate witb the Regional Water Quality
Control Board that the city intends to be involved in tbe consideratIOn of this renewal and
opposes a full five-year renewal of the permit.
. Direct staff to request a status report from the Port District on any current or proposed
lease extension negotiations related to the South Bay plant or the substation and present
results to the Energy Subcommittee or fuIJ Council for direction.
Additionally, we must ensure that the two million stirnulus dollars for energy efficiency block grants
is spent 111 a way that helps us the rnost in getting rid of the South Bay Power Plant. Energy
infrastructure stimulus money should tie in with energy effiClent development based on a
commitment that all new bayfront redevelopment would meet or exceed the lughest energy
efficiency standards.

, Honorable Cheryl Cox
Mayor
City of Chula Vista
276 Fourth Avenue, Iv1S A-101
Chula Vista, CA 91910
Dear Mayor Cox:
Thank you for your letter of January 7,2008, regarding the future of the South Bay Power Plant
("SBPP")., The letter asks the California Independent System Operator (ISO) to respond to the
following questions:
1) What is the function of the SBPP as it relates to reliability and transmission?
2) What needs to occur in order to reduce the reliability designation on the SBPP enough
to allow the lattice towers and transmission lines to be removed by December 2008?
3) What needs to occur in order to eliminate the Reliability Must Run (RMR) designation on
SBPP so that it can be decommissioned and removed by February 2011?
I understand that the City of Chula Vista is in negotiations with various parties' regarding the future
use of the bay front that would require removal of the SBPP, Thus, the timing of the possible
retirement of the SBPP is an important factor in these negotiations, As you know, the generating
units at the SBPP are currently designated by the CAISO as Reliability Must-Run (RMR) units, This
designation cannot be removed until local reliability requirements can be met without the SBPP.
The CAISO is a non profit public benefit corporation chartered under the laws of the State of
California for the purpose of operating and maintaining the reliability of the statewide electric
transmission grid, The reliability of the transmissiof] grid is dependent on a number of specific power
plants located in specific areas. SBPP is, in fact, critical to maintaining the reliability of the San
Diego area, In order to remove the RMR designation from SBPP, the California ISO must find that
reliability requirements can be met without SBPP units.
In May .2007, San Diego Gas & Electric ("SDG&E") entered into an agreement with the operator of
the SBPP to fill SDG&E's Local Capacity Area Resource requirement needs as mandated by the
California Public Utility Commission (CPUC). This agreement runs through December 31, 2009 and

will secure all of the 704-megawatt capacity from the SBPP to the region. Although this agreement
will provide SDG&E more flexibility over the operation of the facility and will ensure that the output
from the plant is available to the CAISO to suppoli the local area needs, the CAISO concluded that
continued RMR designation was required in order to ensure availability of the resource to meet local
reliability needs.
The CAISO is aware of the widespread interest that exists to see SBPP decommissioned and has
been in discussions with SDG&E about the requirements necessary to remove the SBPP'S RMR
designation. In order to remove the RMR designation, there are a number of modifications to the
transmission and/or generation infrastructure that must happen first to ensure that local area
reliability is maintained,
Three projects are underway to meet this local area reliability requirement. First, with respect to the
need for new resources, construction of the Otay Mesa Energy Center is currently underway.
Second, SDG&E has filed an application with the CPUC to construct the Sunrise Powerlink
Transmission Project that will enable SDG&E to substantially improve system reliability and provide
access to renewable resources. Third, SDG&E has recently executed contracts with two developers
for new peaking generation resources in its service territory.
From the CAISO's perspective, at least two out of three of these major modifications must occur
before the RMR designation at the SBPP can be removed. In addition to these modifications, the
new Silvergate 230 kV substation and its related upgrades (scheduled for December 2008) as well
as the new Baja Nolie natural gas interconnection (scheduled for January 2008) must both be in
service.
Given that the Otay Mesa Energy Center is under construction, the future addition of Sunrise
Powerlink would satisfy the requirements for removal of RMR designation at SBPP. If Sunrise is
delayed or not constructed, additional new peaking generation will be required within SDG&E's
service territory. The amount of new capacity would be based on the CAISO's existing grid reliability
standards, which are analyzed each year. Based on the current status of the previously noted
projects, the RMR designation at the SBPP could be removed as early as 2010. However, delays in
construction of the Sunrise Powerlink, lack of sufflcierlt new peaking capacity, or delays in the in-
service dates in implementing the new Baja Nolie rlatural gas interconnectiorl, would clearly delay
this date. Once the RMR desigrlatiorl is removed, there should be no CAISO-related impediment to
retiring and decommissioning SBPP.

I trust that this sheds some light on the California ISO's role in determining the generation and
transmission infrastructure necessary to ensure grid reliability and its analysis of local reliability
needs related to the SBPP, If you have additional questions, please call AIi Chowdhury, Director of
Regional Transmission South, at (916) 608-1113,

Subject: South Bay Power Plant
Dear Senator Ducheny:
This letter responds to your office's request for additional factual information concerning the
statements in the January 28, 2008 letter from ISO Chief Executive Officer, Yakout Mansour to
Chula Vista Mayor, Cheryl Cox regarding the Reliability Must Run ("RMR") status of South Bay
Power Plant. The purpose of Mr. Mansour's letter was to identify the minimum conditions that
must be met before the ISO would be able to remove the RMR designation of the 708 MW
South Bay Power Plant
In summary, at least two of the following three conditions must be met in order to remove the
RMR designation from the South Bay Power Plant: (1) the Otay Mesa Energy Center must be
in service; (2) the Sunrise Powerlink Transmission Project must be in service; and (3) additional
new peaking generation resources within the SDG&E service area must be available. The letter
also indicated that the Silvergate 230kV substation and its related upgrades as well as the new
Baja Norte natural gas interconnection must both be in service. At the time of the January 28,
2008 letter, the ISO noted that the earliest possible date that the RMR designation could be
removed would be 2010 provided that the above condition was satisfied Finally, the letter noted
that the annual reliability assessments depend on an analysis of all relevant facts and, given
delays or other circumstances unanticipated at that time of the letter, RMR designation may
continue to be necessary beyond 2010.
To bring you up to date, the Otay Mesa project, which will provide 561 MW of new capacity, is
scheduled for completion in 2009. The California Public Utilities Commission has approved the
Sunrise Powerlink project, which has a 1,000 MW transfer capability, and it is currently
scheduled to be completed in June of 2012. If the Sunrise Powerlink project is delayed or
deferred, preliminary load growth estimates indicated that we would need an additional 400 _
500 MWof capacity (i.e. in addition to Otay Mesa) in the San Diego local area in service in 2012
to remove the RMR designation from the South Bay Power Plant beginning as of the 2012 RMR
contract year. These are preliminary estimates and would need to be updated as part of the
ISO's annual local reliability assessment. At this time both the Silvergate and Baja Norte
projects are complete. If the Sunrise Powerlink project is complete and in service on schedule,
the ISO would be in a position terminate the RMR contract at the end of the 2012 RMR contract
year.
Hon. Denise Moreno Ducheny
April 1 , 2009
Page 2 of 2
Finally, the ISO is contractually required to make its decision to extend the term of the RMR
contract by October 1 of each year for the following year. If there is any doubt as to the whether
the Sunrise Powerlink project would not be in service by the end of 2012, the ISO will have to
extend the term of the contract for the 2013 RMR contract year.
We hope this information is helpful. Please feel free to contact me if you have any questions, I
can be reached at (916) 802-3576.

Subject: MMC Chula Vista and Reliability Must-Run Status of the South Bay,Power Plant
Dear Ms. Luckhardt
This letter responds to your June 25, 20G8 letter conceming the. relationship between your client's Chula
Vista Energy Upgrade Project (Project) and the Reliability Must-Run (RMR) status of the South Bay Power
Plant (SBPP). Specifically, you request clarification concerning a statement allegedly attributed to a
representative of the California Independent System Operator Corporation (CAISO) at a meeting with the
City of Chula Vista, that the additional capacity created by the Project "could not be counted to support the
removal of the RMR designation" of the SBPP.
To set the record straight, consistent with CAISO CEO Yakoul Mansour's January 28, 2008 letter to Chula
Vista Mayor Cheryl Cox, any new resource, with Resource Adequacy (RA) deliverable capacity, located
within the San Diego local area would contribute toward the peaking resources required (including your
client's Project) to meet the capacity need tor San Diego local area reliability. In other words, in the event
either the Otay Mesa Energy Center or Sunrise Power Link Transmission Project is delayed, the capacity of
the Project would contribute to meeting San Diego's local reliability requirements provided that sufficient
additional new capacity in the San Diego local area were. available in order to allow tor the entire SBPP to
be retired.
As noted in Mr. Mansour's January 28, 2008 letter, two infrastructure enhancements will also be needed:
the Silvergate 230kV substation and the new Baja None natural gas interconnection projects must both be
in service. In addition, local capacity is not the only local reliability need served by SBPP. SBPP also has
black start and dual-fuel capabilities. Belore the CAISO releases SBPP, the CAISO must be satislied that.
suitable alternatives are available that would replace these services or obviate the need for these serviceS.
We hope this letter provides the clarification that you requested. Should you have any questions regarding
this letter, please contact Catalin Micsa at (916) 608-5704 (cmicsa@caiso.com), Irina Green at (916) 608-

CITY OF
(HULA VISTA
Department of Public Works
DATE:
April 21, 2009
VIA:
The Honorable Mayor and City Council
Jim Sandoval, City Manager~.,-.-
Scott Tulloch, Assistant City ~nager 7 )
TO:
FROM:
R. A. Hopkins, Director of Public Works'
SUBJECT:
Emergency StOl1l1 Drain Repairs at: (1) Helix Avenue, (2) EI Capitan Drive,
(3) Neptune Drive, and (4) Grand Teton Drive
In February and March 2009, corrugated metal pipe (CMP) storm drain failures were discovered
at three locations in close proximity to residential structures in the City of Chula Vista. These
failures occurred at (I) 882 Helix Avenue, (2) 106 EI Capitan Drive, and (3) 1188 Neptune
Drive. Each of these CMP failures, if not repaired, poses an imminent threat to public safety and
private property. In addition, staff was made aware of a 7-ft by 7-ft by 10-ft deep sinkhole on
Thursday, February 19, 2009 that had developed at 1526 Grand Teton Court, as reported in a
February 23, 2009 Information Item to City Council, due to the displacement of concrete storm
drain pipe segments. All of these emergency repairs must be undertaken to protect life and
property and are being funded using General Fund Reserves.
Due to heightened awareness of significant corrugated metal pipe (CMP) failures throughout San
Diego County in 2004 and 2005, on March 22, 2005, the City contracted with Hirsch &
Company Consulting Engineers to evaluate the existing condition of the approximately 88,000
lineal feet of cOITugated metal pipe (CMP) storm drain within the city limits. In November 2005,
Hirsch & Company delivered a prioritized CMP repair report listing all inspected CMPs, with
the associated recommended priority and recommended timing for the rehabilitation of each pipe
segment. Due to the conditions of the inspected pipes and the projected rates of deterioration of
these pipes, the consultant recommended that all pipes be replaced or structurally lined within
one to five years of the report's submittal.
The November 2005 Hirsch repol1 prioritized all CMP repair work as followed:
Priority Time Repair Needed (Year) Lineal Feet of CMP
1 Immediately (2005) 2,282 ft
2 Within one year (2006) 21,858 ft
3 Within three years (2008) 9,698 ft
4 Within five years (2010) 2,437 ft
The Honorable Mayor and City Council
April 21, 2009
Page 2
Much of the approximately 2,282 lineal feet of existing CMP identified as "Priority I" has been
rehabilitated, largely due to funding provided to the City through the Federal Department of
Housing and Urban Development. However, none of the CMP under Priorities 2, 3 and 4,
totaling approximately 33,993 lineal feet, has been addressed, due to budget constraints and the
lack of dedicated funding for CMP rehabilitation and drainage projects. As a result, CMPs in
Priorities 2, 3, and 4 are currently rehabilitated on an emergency basis only as failures occur,
which is costly and inefficient compared to performing rehabilitation on a prescribed priority
schedule. Further, without a dedicated funding source to rehabilitate these pipes and with the
passage of time, the rates of deterioration and failure will increase into the foreseeable future.
Each of the ClllTent storm drain repairs are being performed on an emergency basis in accordance
with provisions in Section 1009 of the City Charter. Public Works staff has taken precautionary
measures where deemed necessary to provide protection and safety in the interim, until
permanent repairs may be implemented.
An emergency contract has been let to Cass Construction Company for the repair of the concrete
storm drain system and embankment at 1526 Grand Teton Court. This work is currently
underway.
FISCAL IMPACT
There are no direct or dedicated funding sources for the maintenance and repair of storm drain
facilities; therefore, General Fund Reserves are used to fund this type of work, but only on an
emergency basis. Staff will return with an item on May 12 for appropriation of funds.
Emergency repair costs will be presented to City Council upon completion of emergency work.
