Fiscal Impact The total cost for Change Order No. 48, including a contingency, is outlined below: Descri tion Estimated Cost Start Motor and En ineerin $653,900 Installation Services $118,102 Tax $47,500 Contin enc $200,�00 TOTAL $1,019,902 Report to Redding City Council Apri130,2025 Re: 4.5(a)--Budget Reso& Change Order for Unit 5 Start Motor Replacement Page 2 This project entails the replacement of the undersized starting motor for Generating Unit 5 to restore proper functionality. Due to the extended lead time required for the design and procurement of the new start motor and supporting structure, it is essential to finalize the change order before the end of the fiscal year. Funding for this capital project will be sourced from bond proceeds resulting in no fiscal impact to unrestricted reserves. Due to ongoing political uncertainty in the United States, Siemens Energy cannot accurately project future tariff rates. Consequently, the requested contingency amount includes a potential. 25 percent tariff on imports from Europe. If this tariff is enacted, the City Manager wi11 instruct staff to amend the Change Order 48 to reflect the additional cost, if any. Alte�native Action The City Council may choose not to approve the project to replace the Generating Unit 5 start motor and provide alternate direction to staff. Backg�ound/Analysis Generating Unit 5 has a power output of approximately 45 megawatts (MW) and uses waste heat recovery to produce an additional 15 MW of steam power for Generating Unit 4. The combined power generation of 60 MW accounts for approximately 30 percent of the 185-MW total capacity of the Redding Power Plant. Generating Unit 5 is a critical resource for REU's power portfolio. There are two reasons that the start motor for Generating Unit S is no longer adequate for the application: (1) Over the past 20-years, changes in the control scheme of the generating unit have been made by the manufacturer that have 1ed to increased power demand on the motor; because of these changes, the motor frequently exceeds its amperage and temperature rating, especially during summer months when it is most needed; and exceeding these ratings pose personnel safety and equipment integrity risks; (2) The changing power market is anticipated to increase the need for start cycles on Generating Unit 5, which will increase the demands placed on the Inotor; it is unlikely that the existing start motor will be able to meet the needs of the future power market profile. The start motor on Generating Unit 6 was replaced with a new motor in 2016. The new start motor is oil cooled instead of air cooled, so it is better able to handle multiple starts, even on hot days. By replacing the start motor on Generating Unit 5, both motors wi11 be the same and one spare motor will serve both units. At the present time, two different motors are needed for spares. Environmental Review This repair is categorically exempt from review under the California Environmental Quality Act pursuant to Sections 15301 (Existing Facilities) and 15302 (Replacement or Reconstruction). Council Priority/City Manager Goals This is a routine operational item.

Re-Use of Existing Components Existing components that will be re-used are assumed to be undamaged, free from significant defects, and in serviceable condition. Any components found to be unusable will be identified to the Client and quoted at the time of discovery. Costs and/or delays associated with unusable, existing components will be the sole responsibility of the Client. 2. Compressor Noise Noise measurements are subject to many environmental factors beyond SEI control; thus, no guarantee of maximum noise level shall be made. Any estimated sound pressure levels provided are for information only. SEI is willing to assist the client with any required corrective action at the client's expense. Assistance can include aid in design, construction, and installation of suitabie modifications to reduce the noise to an acceptable level. 3. Special Shipping Packaging The supplied components will be packaged for either long- or short-term storage and wood packaging may be fumigated depending on the end-user location or preferences. If no special shipping packaging is necessary or required by the client, SEI will proceed with employing internal shipping and packaging standards. Note:SEI shipping packaging standards can be suppiied upon request. 4. Specialized Cleaning for Chlorine Service Chlorine gas can react with any residues of grease,wax,or oil present in the compressor flow path. This exothermic reaction has the potential to cause a chlorine-iron fire. As such, SEI highly recommends that specialized cleaning of compressor flow path components in direct contact with process gas is conducted during the assembly process. This scope is not included with this offer but can be quoted separately by a SEI service center specifically approved for servicing chlorine units. Copyright 2025 Siemens Energy, Inc.

Removal of bolts, studs, pins, keys and other parts by burning,freezing,drilling, machining or by other abnormal means if required shall be provided on a T&M basis as Extra Work under our current published rate sheet. The Purchaser shall furnish new hardware when destructive removal is necessary at no charge to SEI. SEI will discuss this abnormal procedure with the Purchaser unless the problem occurs off hours, and a schedule delay would result. 2. Monitoring for and removal andlor disposal of all hazardous material such as asbestos bearing materials, lead carbonate, etc. are not included in SEI proposal. 3. Removal and reinstallation of the fire protection system, including fire protection instrumentation, electrical equipment and instrumentation, conduit and piping are not included in this proposal. All electrical disconnects (motors, generator bus, etc.) are to be performed by Purchaser. 4. The Purchaser will provide all spare parts. �ack of spare parts when needed may delay the completion of work. Any such delay will be billed to the Purchaser on a T&M basis per the current rate sheet. Large spare parts and materials, which cannot be transported easily by hand, are to be provided by the Purchaser directly on the equipment deck or under the station crane prior to the outage start date. 5. Supplier will provide general tooling for the scope of work. No special tooling required. Copyright 2025 Siemens Energy, Inc. Page Z3 of 29 SF242276021,Rev.4 All rights reserved. Siemens Energy, Inc.Confidential March 31,2025 Siemens Energy is a trademark licensed by Siemens AG. 6. The Purchaser is responsible for the proper operation and availability of the overhead crane. A crane inspection is required, and a load test performed prior to the outage (no more than 12 months prior). The crane shall be made available to SEI and its subcontractors on a priority basis; however, SEI will share the use of the crane in order not to adversely impact the outage completion. Any and all crane delays/problems will result in a delay charge to Purchaser. 7. In the event that the Purchaser provides scaffolding, SEI Quality Assurance guidelines require that the Purchaser ensures that the scaffolding is inspected by qualified personnel prior to each shift. The Purchaser is to ensure that qualified inspection personnel are available each day that the scaffolding is in use. 8. The Purchaser is responsible for directing SEI regarding where to place heavy loads on the equipment deck (i.e. lay down location, rotors, etc.) in order to comply with the design floor-loading plan. 9. In order to assure effective communication and timely response to project needs, it is expected that the Purchaser will provide a Plant Contact with EWA signatory authority on a 24-hour basis for the work duration for assistance during the outage to avoid delays of the project. The Purchaser and SEI would each provide persons for interfacing, with the authority to represent their companies during the time SEI is performing work. 10.The craft manpower loading, and work schedule may change depending on the work scope, inspection findings and at SEI discretion. Any schedule float on SEI tasks will be the exclusive property of SEI. 11. Rotating and stationary component repairs beyond what is explicitly included in this proposal are not included in the price. SEI can offer repair as an option and, dependent on requirements, can either complete the repair on site or ship parts to one of SEI's authorized workshops. 1 z.Should disassembly andlor inspection findings reveal that machining is necessary, the Purchaser will be notified, and a quote revision will be made in accordance with the Extra Work and Contingency Planning 13.SEI will communicate inspection findings and any recommended repair scopes to the Purchaser at the conclusion of the inspection process. 14. Purchaser will remove and replace the lubrication oil and the control fluid, if required, and inspect and clean the tanks. The Purchaser will provide the necessary jumpers and/or fittings to complete lube oil and control fluid flush. Normal flush time is 1 Z hours and SEI recommends this duration even in cases when new oil is supplied. 15. It is anticipated that there will be no delays caused by the Purchaser for safety related issues, special permitting requirements, work area admittance, plant admittance, or safety meetings and pre-outage orientation during the entire outage exceeding a total of 2 hours per person. Such delays impact the schedule and will be billed on a T&M basis per the current rate sheet. SEI shall not be held responsible for delays resulting from the actions of the Purchaser or other personnel not subcontracted by SEI. 16.Checking the coupling alignment is included in the price. (The SEI standard methods are rim and face dial indicator, reverse dial indicator, and straight edgelfeeler gauge.) Major realignment (moving the case), if required, will be considered Extra Work and will affect the outage duration and cost. The determination will be made when the coupling reference readings are recorded following the unit cool down. Copyright 2025 Siemens Energy, Inc. Page 24 of 29 SF242276021,Rev.4 All rights reserved.
