Electrical Engineer

Project Overview

Our customer is a utility in central Arizona looking to add 2000MW of pumped energy storage to its storage capacity to meet growing demand on its network. We are building a high performing team to deliver this complex EPC heavy civil project and looking for motivated, hands‑on, collaborative innovators, doers, and problem solvers. The project will involve the use of the existing Apache lake as the lower reservoir and creation of an upper reservoir by building dams in the Alchesay Canon, the reservoirs will be connected by underground waterways tunneled into the rock, channeling water down the ~1,200ft drop between the two reservoirs.

The project scope includes significant access roads work development, construction of the upper reservoir with dams and an overflow spillway, underground tunnel waterways in challenging geological and hydrogeological conditions, upper and lower reservoir inlet/outlet structures, hydromechanical equipment, an underground powerhouse, and surface site facilities and buildings. The Electrical scope includes a 500kV system comprising of incoming power lines, above ground takeoff structures, 500 kV cables routed via underground tunnels, 500 kV Gas Insulated Switchgear (GIS) substation and Generator Step Up (GSU) transformers inside a cavern as well as other BOP electrical equipment (medium voltage transformers, medium voltage switch gear, distribution transformers, low voltage switch gear and panel boards).

The Senior Electrical Engineer is responsible for the engineering, coordination, and technical oversight of powerhouse and balance of plant electrical systems for the Salt River Project Pumped Storage Project (SRPSP).

The role supports EPC execution through design development, interface management, constructability, and construction/commissioning support for a large, pumped storage facility comprising underground powerhouse, shafts, tunnels, intake/outlet works, and surface facilities, in accordance with SRP requirements, applicable codes, and Bechtel engineering procedures.

A key part of this role is collaboration with JV partner, Design consultant and the Customer. The Senior Electrical Engineer shall work with the team to establish regular meetings with design consultant and other external stakeholders as required and reporting cycles for managing, coordinating, and assuring the design.

The position is based at our design subcontractor offices in Edmonton, Canada with regular attendance at the central design office in Phoenix, Arizona. During construction, the role may transfer to site or require regular site attendance.

• Perform and review conceptual, preliminary, and detailed design for SRPSP BOP electrical systems, including:
  • Medium and Low Voltage distribution within the underground powerhouse and plant facilities
  • Unit auxiliary systems, station service power, black start and emergency power provisions
  • Grounding, bonding, and lightning protection for underground and surface facilities
  • Powerhouse, access tunnel, and cavern lighting (normal, emergency, maintenance)
  • Cable tray, conduit, shaft, and tunnel routing systems, including segregation and installation constraints
  • Electrical systems supporting cranes, hoists, gates, valves, drainage, dewatering, ventilation, HVAC, and other BOP equipment
• This role will include working with the Design Subcontractor and discharging responsibilities as set out in the Management of Third‑Party Engineering, 10G-M41-00013 as part of the BTJV Engineering team.
• Develop and check electrical design criteria, load lists, calculations, single line diagrams, layouts, specifications, and data sheets consistent with SRPSP operational, reliability, and safety requirements.
• Coordinate electrical designs with Civil / Geotechnical (underground caverns, shafts, tunnels, powerhouse layout), Mechanical (turbine generator auxiliaries, pump motor auxiliaries, gates, HVAC), Control Systems / I&C (auxiliaries control, power/controls segregation, UPS interfaces) and Plant Design and Constructability.
• Interface with OEMs (turbine generator supplier, auxiliary equipment vendors) for electrical integration into SRPSP powerhouse systems.
• Support and management of electrical interfaces between:
  Powerhouse and switchyard / transmission tie‑in, Underground works and surface facilities and Permanent and temporary construction power.
• Provide Construction & Commissioning Support during execution including response to RFIs, field change evaluations, etc.
• Support construction sequencing, installation constraints, and temporary power planning for underground works.
• Participate in testing, energization, and commissioning support, including review of test procedures, energization and turnover sequencing for station service and auxiliaries.
• Support SRP operations readiness and commissioning teams.
• Review and approve electrical deliverables to ensure compliance with SRP technical requirements, project specifications and design criteria, applicable…
