1 Introduction and Overview SLAC receives power at its Master Substation (MSS) from a PG&E 230kV transmission line via two 230kV/12.47kV stepdown transformers. SLAC identifies that its AC power system encounters power factor issues at the point of connection (POC) with PG&E, where the power factor strays outside the contractual range (0.97 lag to 0.99 lead). This deviation stems from various factors, including reactive power imbalances, capacitive or inductive loads, etc. Consequently, suboptimal power factor conditions can result in increased power losses, reduced system efficiency, and involve potential penalties imposed by PG&E.

To address this challenge, SLAC plans to implement power factor correction measures through the installation of two switched power factor correction (PFC) systems – one on 12.47 kV Bus-1 and another on 12.47kV Bus-2 at the Master Substation (MSS). These PFC units will dynamically improve reactive power flow, compensating for system reactive power demand, and maintaining the overall power factor within the required range. Enhancing power factor correction in this manner will optimize energy utilization, reduce system losses, and ensure continued compliance with PG&E contractual requirements.

2 Purpose Prior to the installation of the new power factor correction equipment, it is necessary to demolish existing buildings (B308 and B311) with equipment inside them to create adequate space within the MSS Yard.

This Statement of Work outlines the scope for the demolition, disassembly, and removal of existing assets, including metal buildings B308 and B311, a non-operational synchronous condenser, and the associated electrical equipment and cabling and wiring serving the condenser. All identified buildings and equipment are located in the SLAC MSS Yard.

The intent of this document is to also provide the Subcontractor with a basic insight into the type and magnitude of the project, safety compliance issues, and technical and project management requirements.

3 Location Perform onsite support work outlined in this SOW at SLAC National Accelerator Laboratory, 2575 Sand Hill Road, Menlo Park, San Mateo County, 94025, California, at the specified location.

4 Scope of Work

1. The Subcontractor shall furnish all labor, materials, tools, equipment, and incidentals necessary to perform and complete the work indicated in this SOW.

2. This SOW defines the intended outcomes of the work, identifies applicable reference standards, and provides relevant technical requirements. All work shall be performed in accordance with applicable industry standards, codes, and SLAC requirements.

3. All work shall be performed within an active substation yard. Subcontractor personnel shall be escorted at all times by a SLAC employee, typically a High Voltage Electrician or a qualified Construction Manager. The subcontractor shall coordinate all activities with the assigned Construction Manager.

4. The Subcontractor shall provide all “temporary construction power” for the execution of the work.

4.1 System to Remain

A. Existing Ground grid – maintain and preserve the ground grid; any unavoidable impacts shall be coordinated with SLAC in advance.

5 Qualifications

1. Subcontractor shall be capable of successful project outcomes and demonstrate their experience in self-performed work and partnering with sub-tier firms.

2. Subcontractor shall demonstrate key personnel have experience from successful execution of past projects and current relationships with partners.

3. Subcontractor shall demonstrate they and their sub-tiers have experience working in an operational critical facility, such as a main substation.

7 Deliverables

SLAC-I-708-905-023 Page 8 of 9

1. Schedule and Work Planning & Controls

a. Provide a schedule of major work activities

b. Provide work plans for high-risk critical activities

c. Provide Job Hazard Analysis (JHA)

d. Complete Daily Safety Tailgates

2. Execution

a. The Subcontractor shall verify existing conditions prior to the start of work.

b. The Subcontractor shall identify any ambiguity in the drawings and work with SLAC

SMEs to verify existing conditions. These gaps shall be resolved via RFI’s and captured as red-lines on the field drawing set.

c. Work shall be coordinated with the CM and with SLAC HV electricians.

d. A Red-lined drawing set shall be available in the field.

e. Subcontractor is to conduct daily safety tailgate meetings prior to start of work

3. Project Acceptance

a. Perform project close-out inspections and provide documentation as required by the contract.

b. Complete the project close-out punch list provided by SLAC.

4. Demo Disposal Clarifications:

a. Synchronous Condenser’s Weight approximation: 110,000 lbs.

b. The building and equipment materials are to be disassembled into pieces/convenient sizes and separated into SLAC provided bins (for metal, wire, and “breakage”) and removed for salvage by SLAC. GC activities shall be coordinated with the CM and SLAC Salvage.

c. The removed Class II concrete and soil materials are to be placed in SLAC provided bins and disposed of by SLAC. GC activities shall be coordinated with the CM and SLAC Waste Management.

d. Due to the clearance limitations from the 230kV overhead power lines in the MSS yard, large/tall vehicles and cranes cannot be used. A 20’ wide by 11’ high “stay within” limit is defined to maintain the proper distance from the energized components.
