The Plan has been implemented as follows: Effective Date and Time: 07-31-2000 at 14:54 Effective Hours: Approximately 04 hours. (HE1500 through HE1900) Reason(s): Second Stage 2 notice Your response: PG&E requests NCPA achieve 3MW total voluntary load curtailment. NCPA requests Palo Alto and Roseville each implement 1.5MW each. Participating transmission owners are to notify the Utility Distribution Companies within their operational areas. STAGE 2: Operating reserves are expected to fall below 5%. The UDC will implement interruptible service programs as directed by the ISO and will take all additional actions necessary in preparation for immediate implementation of electrical emergency plans and await further orders from the ISO. This message is from Market Operations (916-351-2494) at the California ISO. Please call Central Dispatch at (916) 786-3518 or Al Parsons at 916-781-4225.

Lodi Interconnection Project • Increased Reliability — Full transformer and transmission line redundancy — Added generation capacity from the west — Unloads PG&E system improving Lodi area reliability • Electric System Studies - Western — Improves 27 system elements of 36 presently overloaded — 16 MW load reduction vs. loss of entire City for N-1 LODI INTERCONNECTION PROJECT The proposed Interconnection project will connect Lodi's electric system with the 230kV Transmission System to the West of Interstate 5. This project will provide many benefits to Lodi and the surrounding community. 1) The Western Area Power Administration (Western) has performed electric system studies to identify the impacts of the proposed interconnection. The study uses the latest data and criteria available provided by PG&E and the Sacramento Area Study Group. The Lodi Interconnection Study Final Report is dated June 5, 2000. The study results include the following benefits: 2) Increased reliability and operational flexibility with the addition of the Interconnection. 3) Increased ability for Lodi to serve electrical Toads in the western part of Lodi's service area. 4) Taking service at 230kV from Western may prove to be more economical than relying totally on a 60kV interconnection with PG&E.

Of theses 36 elements, four remain unchanged, 27 will improve and five will get worse. The following tables show the comparison in the loading of transmission lines and transformers before and after this interconnection for base case and n-1 contingencies for some selected elements. The complete tables are in the Appendix IV. As shown in these tables the City's interconnection to Western has a marginal effect on these overloads and the overloads are mostly improved. There are five elements with increases in their overloads; of these five elements, the worse overloads are Bellota 230/115 -kV transformer by 1.62% and Tracy 500/230 -kV transformer by 1.4%. Another group is addressing the Tracy transformer overload. Table III Selected Base Case Overloads With and Without City Connected to Western 230 -kV and Up .

Pine Street Lodi, CA 95240 Subject: Alternative Power Sources for Lodi Subsequent to your meeting with the Agribusiness Comrnitte, the committee approached the board of directors asking that we form a task force to meet with you in order to explore alternative routes for bring power into the west side of Lodi. The folowing motion was passed at our board meeting on June 16, 1998. "The Lodi District Chamber of Commerce recognizes the need to study the routing plans for an alternative electric power source and therefore has formed a task force to meet with the City to help in the determination of an acceptable route.". Tin' committee will consist of six members representing industry, agriculture, economic development and small business. John Ledbetter will chair the committee. It is our hope that we will be able to work with you in determining some alternatives that will bring power to Lodi at a reasonable cost and meet some of the concerns of agriculture and tourist interests. Very truly yours. Anthony Trassare Chairman. Board of Directors 35 S.

Lodi, Ca 95242-3995 November 4, 1998 Re: Pacific Bell Facilities Relocation (aerial to underground relocation) - along Hwy. 12 from Lower Sacramento Rd. to Ray Rd. Dear Mr. Hansen, Pacific Bell has proceeded with your requests to provide an estimate on the costs involved with undergrounding aerial facilities along Highway 12 from Lower Sacramento Rd. to Ray Rd. The estimated cost of this project would be approximately S901,257.29. The cost estimate being provide to you is only an estimate, and was based on measurements taken in the field. Included in the costs are all labor and material associated with the replacement of all existing facilities and service's. A separate cost for a joint undergrounding was not provided, instead the cost of a typical joint trench to Pacific Bell was used in the estimate. We look forward to working with you on this project and hope that the information provided will aid you in your decisions. Should you have any further questions regarding this estimate or this project please feel free to contact either myself or Helen Hoskins, Engineering Manager at 209-474-4760.
