REPORT TO COUNCIL
SUBJECT
Title
Action on a Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program and Route Approval for the Silicon Valley Power 115 kilovolt Transmission Line from the Northern Receiving Station to the Kifer Receiving Station
Report
BACKGROUND
On September 28, 2021, City Council accepted Silicon Valley Power's (SVP) Three-Year System Growth Strategy Plan (RTC 21-871). The Three-Year System Growth Strategy Plan identified proposed projects for both near-term and long-term capital improvement projects needed to support anticipated system growth and to replace end-of life equipment to ensure system reliability. One of the necessary near-term projects is the construction of a new 115 kilovolt (kV) transmission line between the Northern Receiving Station (NRS) and Kifer Receiving Station (KRS). Constructing the 115kV transmission line will allow energy to be balanced and redistributed within SVP's transmission receiving stations and allow SVP to serve the new load growth projected based on the SVP Resource Load Forecast. The three receiving stations [NRS, Scott Receiving Station (SRS), and KRS] within the City of Santa Clara (City) are all interconnected. As approved by the City Council, SRS and KRS are being fully rebuilt and NRS is being upgraded and expanded to replace obsolete infrastructure and accommodate future growth.
The NRS and SRS sites are currently directly connected via two 115kV lines, which are owned by PG&E. The NRS site is connected to PG&E's system via three 115kV transmission lines and one 230kV transmission line. The KRS site has two 115kV transmission lines connected with PG&E. A second 230kV transmission line is being designed to connect to NRS which will be owned and operated by LS Power and rated for 500MW (recently updated to a 1000MW line that will be considered for approval November 2024). To transfer this additional power and balance loads between the receiving stations, a new 115kV trans...
