How to Apply for Substation O&M Field Engineer

at Clearway Energy Group

🏢 About Clearway Energy Group

Clearway Energy Group is one of the largest renewable energy operators in the US, offsetting 10.5 million metric tons of carbon emissions annually. Their focus on wind, solar, and storage projects offers a chance to work on cutting-edge clean energy infrastructure while contributing to meaningful climate impact.

About This Role

As a Substation O&M Field Engineer, you'll be the technical backbone for high-voltage substations across wind and solar plants in Texas and the central US. Your work ensures safe, reliable power transmission and directly supports grid stability, making you a critical player in the renewable energy transition.

💡 A Day in the Life

Start your day reviewing emails from site managers about equipment alarms or relay events. You might remotely query a SEL relay to analyze a fault, then travel to a wind farm to supervise a transformer outage, training local techs on grounding procedures. Afternoons involve writing maintenance procedures or reviewing NERC compliance reports from your home office.

Practice questions for this role

🎯 Who Clearway Energy Group Is Looking For

  • Has a BS in Electrical Engineering (power systems focus) or 5+ years hands-on experience with HV substation equipment, including breakers, transformers, and switchgear.
  • Skilled in reading electrical schematics and wiring diagrams, and experienced with high-voltage testing equipment (e.g., megger, hi-pot, relay test sets).
  • Proficient in querying SEL protective relays for fault analysis and troubleshooting, with working knowledge of NERC compliance standards.
  • Comfortable working remotely but traveling to field sites (50%+ travel) and training site personnel on substation safety and maintenance procedures.

📝 Tips for Applying to Clearway Energy Group

1

Highlight specific experience with SEL relays (e.g., SEL-421, SEL-751) and any relay event analysis you've performed.

2

Include examples of developing LOTO or HV switching procedures—mentioning NERC compliance is a plus.

3

Quantify your hands-on substation experience: number of outages supported, voltage levels worked on, or megawatts affected.

4

Tailor your resume to show both technical depth (testing, schematics) and soft skills (training, contractor supervision).

5

If your degree isn't power-focused, emphasize relevant coursework or certifications (e.g., NERC certification, OSHA 30).

✉️ What to Emphasize in Your Cover Letter

['Emphasize your passion for renewable energy and how this role directly contributes to carbon reduction goals.', 'Detail your hands-on experience with HV equipment and SEL relays, linking it to troubleshooting and reliability.', 'Show your ability to train and lead site personnel, highlighting safety-first mindset and procedure development.', 'Mention willingness to travel extensively across Texas and central US and adapt to remote work dynamics.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Review Clearway's project portfolio, especially wind and solar farms in Texas and the central US (e.g., Mesquite Star, Rosamond).
  • → Understand their commitment to safety and sustainability—look for their safety record or ESG reports.
  • → Familiarize yourself with common SEL relay models (SEL-421, SEL-751) and their querying software (AcSELerator).
  • → Check recent news about Clearway's expansion or technological innovations in substation automation.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a time you diagnosed a substation fault using SEL relay event reports. What steps did you take?
2 How would you create a safe LOTO procedure for a 345kV breaker replacement? Walk through key steps.
3 Explain how you would train a site technician with minimal substation experience on HV switching safety.
4 What NERC compliance standards are most relevant to substation O&M, and how have you supported them?
5 Given remote work, how do you stay organized and communicate effectively with field teams across multiple sites?

⚠️ Common Mistakes to Avoid

  • Downplaying travel requirements—this role involves significant travel (50%+), and flexibility is key.
  • Lack of specific relay experience—generic electrical engineering skills won't suffice; highlight SEL or similar.
  • Ignoring safety protocols—failing to emphasize LOTO, HV switching, or NERC compliance can be a dealbreaker.
