Position Summary

Commissioning Engineer – responsible for commissioning transmission and distribution substation additions or modifications. This role ensures that equipment is installed, tested, energized and released for service correctly while providing safety oversight and correcting any design or installation errors before energization.

• Review specifications and engineering drawings to understand substation purpose and functionality.
• Schedule installation and commissioning with subcontractors and customers.
• Provide safety analysis and proper equipment isolation procedures.
• Develop day‑to‑day outage plans for customers.
• Create detailed test procedures and sign‑off sheets for each piece of equipment.
• Monitor construction and respond to technical questions arising during installation and testing.
• Identify and resolve design errors.
• Assist field crews and dispatch in developing, switching to proper sequence, and establishing hold points for testing.
• Direct or witness critical tests such as DC Functional Trip Testing prior to energization and in‑service.
• Direct crews during critical work junctures, typically during final commission, just prior, and through initial energization.
• Acknowledge substation modifications are complete and functional, then formally hand over to Dispatch for operation within design limits.
• Support multiple capital projects concurrently, rotating among jobs, reviewing test results, monitoring work, and anticipating problems.
• Work extended hours/days in a row near project completion when control schemes must be functionally tested and equipment energized.
• Develop and maintain strong relationships with customers, understanding their needs, preferences, and constraints.
• Manage resources and services required to install electrical equipment.

• Experience: 3+ years with capabilities in the following areas:
• In‑depth understanding of:
• Three‑phase power systems
• Protection and control schemes and implementation
• Equipment testing – circuit breakers, transformers, circuit switchers, MOABS, CTs, PTs, batteries and chargers, transfer switches, line tuners, wave traps, carrier relays, etc.
• Experience in:
• Testing, troubleshooting, evaluating, and servicing electrical distribution and control systems
• Utilizing relay secondary injection test sets
• PQ measurements
• Leading crews to test and commission new and modified substations
• Rotating machinery, including generators and excitation systems
• SCADA, RTU, and DFR systems
• AutoCAD (desired)

Work will be mostly onsite at clients primarily in Maine and Northern Massachusetts.
