IN THE MATTER OF SUPPORTING THE ] RESOLUTION NO. 991607
PACIFIC CTAS AND ELECTRIC COMPANY ]
TRI-VALLEY UPGRADE PROJECT ]
WHEREAS,the electrical demand in the Tri-Valley region is nearing the area's electric system's
capacity and is expected to exceed it by mid-2002;
WHEREAS, to keep the electrical system at its traditionally high reliability level and avoid
blackouts at peak hours,PG&E must upgrade the region's electrical system and infrastructure,
WHEREAS,to upgrade the system,PG&E plans to build two new substations and construct new
power lines capable of delivering more electricity to the region;
WHEREAS, in working with the community to develop plans for the upgraded system,PG&E
has focused on environmental,engineering and economic factors;
WHEREAS, PG&E has met with local agency representatives in recent months to discuss and
develop alternatives for supplying the electrical energy needs of the developments envisioned
and approved by the local jurisdictions;
WHEREAS,PG&E's preferred alternative for the Tri-Valley Upgrade Project is shown on the
attached map and is comprised of(i) a northern component consisting of two five-acre 230/21
kV substations, approximately seven miles of 230 kV transmission line extending along
existing PG&E right-of-way from the existing Contra Costa-Newark transmission line to a new
Dublin substation and approximately one mile of 230 kV transmission line extending along
North Livermore Avenue to a new North Livermore substation at May School Road;
(ii)a southern component consisting of approximately 6 miles of new 230 kV transmission line
2.7 miles of which will be located underground within Pleasanton city streets, connecting the
existing Vineyard substation and the Contra Costa-Newark transmission line and
(iii) if electric demand increases, a second phase, consisting of a new 230 kV transmission
line along PG&E's existing northern right-of-way connecting the existing Contra Costa line
to the Tesia substation;
WHEREAS, PG&E has been communicating directly with the public in order to build an
understanding of the need for the upgrade, as well as to gain input and insight into specific
concerns raised through the community;
WHEREAS,PG&E intends to file an application with the California Public Utilities
Commission(CPUC)on or about November 22, 1999, for a certificate of Public Convenience
and Necessity(CPCN)authorizing construction of the above project,together with a proponent's
Environmental Assessment(PEA);
WHEREAS, at that time,PG&E will provide notice to, among others, all public agencies having
an interest in the project and make available the Application and the PEA for review;
WHEREAS,the CPUC will likely issue a draft Environmental Impact Report(EIR) analyzing
the projects potential environmental effects for formal public review and comment in late 2000;
WHEREAS,this resolution is in advance of that review and is intended to illustrate a high level
of interest in the project;
