EXHIBIT A- SCOPE OF WORK -AMENDED JANUARY 1, 2023
Project Description
Customer and City entered into a substation agreement on November 22, 2004 for the construction of Juliette Substation and, pursuant to that agreement, Customer dedicated that substation to the City. The City currently owns and operates Juliette Substation, which is fully dedicated to Customer. To support Customer's increased load growth at the Juliette Substation, SVP will contract with Delta Star, Inc. or any successor entity to Delta Star (Delta Star) to perform work to increase the capacity rating for the existing two transformers at the Juliette Substation. This re-rate upgrade will increase the capacity rating of each transformer from 50MVA to 62MV A. This scope includes work performed by Delta Star and by SVP.
Scope
The scope of work to be performed by Delta Star and SVP includes the purchase and installation of equipment (including labor) and testing identified in Appendix A (Delta Star Scope of Work) as the upgrades necessary to increase the capacity rating on the existing transformers to 62MVA. As further described in Appendix A, Delta Star will provide manpower and equipment to upgrade fans, L V line lead cables, and add single ratio CTs to two 30/40/50 MVA HK Porter Transformers to uprate to 62 MVA. Delta Star wUI provide manpower and equipment to upgrade/add components and retrofit the L TC (TLH-21 to RMV-11) on two 30/40/50 MVA HK Porter Transformers. See Exhibit A for the complete scope of work details.
In addition to services performed by Delta Star, SVP staff will provide staff to complete tasks required for Delta Star's services such as: lockout/tagout, de-energize transformers, isolate transformers (removing conductor leads), install any additional control wiring that may be required, witness testing and commissioning, re-energize transformers, modify SCADA. In addition, SVP staff will provide oversight and project management for the Delta Star services.
Cost Estimate
The Cost Estimate for this work is detailed in Exhibit B - Cost Estimate - Updated January 1, 2023.

4.7. A One-Year (12-month) warranty will be included for all work performed and outlined in Delta Star's proposal and no additional warranty will be provided.
Because this equipment is service-aged and not new, the warranty will be a workmanship warranty only. For clarification purposes, all services pertormed, and components delivered/purchased, will carry Delta Star's standard one-year workmanship warranty. For example, any items disturbed by Delta Star personnel, such as a manhole gasket, would be covered under the warranty. If the manhole leaks during the warranty period, Delta Star would be responsible for repairing it at no cost to SVP. For a component, such as replacing HV bushings but not replacing L V bushings, the warranty would only apply to the newly replaced HV bushings, as an example, and not the existing old L V bushings.
