__________________________________________________)  PROJECT MODIFICATION




On June 17, 2003, the California Energy Commission received a petition from Calpine for its Los Esteros Critical Energy Facility (LECEF) Project requesting approval for a previously completed modification. Additional information was required in order for staff to fully analyze the petition, and staff issued Information Requests on July 29, 2003. Calpine responded to staff's Information Requests on September 5, 2003.

At a regularly scheduled Business Meeting on January 21, 2004, the Commission considered staff's analysis and approved the Petition and the proposed additional conditions in accordance with Title 20, section 1769(a)(3) of the California Code of Regulations.


COMMISSION FINDINGS

Based on staff's analysis, the Energy Commission finds that the modifications already made will not result in any significant impact to public health and safety, or the environment. The Energy Commission finds that:

  • A. The new temporary interconnection tap line is inferior from an operational reliability perspective compared to the permanent interconnection specified in the Decision (a direct connection to the PG&E Los Esteros Substation bus). However, it is acceptable at the present time and it is in accordance with good engineering practices.

  • B. Staff's requirement for the installation of a disconnect/selector switch will improve operational reliability and flexibility.

  • C. There will be no new or additional unmitigated significant environmental impacts associated with the proposed change.

  • D. The facility will remain in compliance with all applicable laws, ordinances, regulations, and standards, subject to the provisions of Public Resources Code section 25523.

  • E. The change is beneficial to the project owner in terms of cost savings in excess of 3 million dollars and the flexibility to later connect to the PG&E Los Esteros Substation or the Silicon Valley Power (SVP) switching station to be built adjacent to LECEF.

  • F. There have been changes in circumstances relating to the electrical distribution/ supply in the North San Jose area. As proposed, the LECEF was to serve as a mitigation project for the U. S. DataPort (USD) Planned Development Zoning Project which was approved by the City of San Jose. USD was planned as an internet data center. It was never built. Also SVP is planning to build a switching station next to LECEF.

With the adoption of staff's two new Conditions of Certification there will be no new or additional unmitigated significant environmental impacts associated with the completed changes.

The facility will remain in compliance with all applicable laws, ordinances, regulations, and standards, subject to the provisions of Public Resources code section 25523.

ORDER

The California Energy Commission hereby approves the Los Esteros Critical Energy Facility petition to use the already installed new temporary interconnection tap line until July 2, 2005. It is further ordered that a three-phase disconnect/selector switch shall be installed within 60 days of this order, or as determined by the Energy Commission Compliance Project Manager as contained in the additions to the existing Conditions of Certification.

NEW CONDITIONS OF CERTIFICATION




TSE-A1: The new temporary tap interconnection shall consist of an approximately 152 foot transmission line under-crossing of the two double circuit PG&E 115 kV steel pole lines (running generally North/South) immediately adjacent to the LECEF power plant switchyard to a hard wire tap of the Nortech-PG&E Los Esteros Substation circuit utilizing three wood poles. The cable size shall be 795 ACSS.
Verification: This configuration has been implemented and conforms to existing LORS.
TSE-A2: To provide adequate operational reliability and flexibility for the new temporary interconnection, a three-phase disconnect/selector switch shall be installed at the interconnection tap point with the Nortech-PG&E Los Esteros Substation 115 kV line to be coordinated between Calpine and PG&E. At the interconnection tap point the switch is required for the circuit to the Nortech Substation.
Verification: TThe project owner shall provide to the CPM adequate documentation that a request for PG&E to install the disconnect/selector switch has been made within 15 days of the Commission's approval of the petition to modify the temporary interconnection tap line. The project owner shall assure that the disconnect/selector switch is installed within 60 days from the Commission's approval of the Calpine petition to modify the temporary interconnection tap line, or as determined by the Energy Commission Compliance Project Manager.
IT IS SO ORDERED. STATE OF CALIFORNIA ENERGY RESOURCES CONSERVATION AND DEVELOPMENT COMMISSION

Date On-Line: May 12, 2004.
