How to Apply for Senior Project Commissioning Engineer - Battery Storage

at Plus Power

🏢 About Plus Power

Plus Power is at the forefront of the renewable energy transition, specializing in utility-scale battery energy storage systems (BESS) that enable a greener grid. Their remote-first culture and focus on cutting-edge technology make them an exciting place for engineers who want to drive impactful projects from start to finish.

About This Role

As a Senior Project Commissioning Engineer, you will lead the technical delivery of BESS projects from design through commissioning, ensuring seamless integration with high-voltage substations and transmission systems. Your work directly enables the reliable operation of grid-scale storage, accelerating the shift to clean energy.

💡 A Day in the Life

A typical day might involve reviewing design drawings for a new BESS substation, then hopping on a call with an EPC contractor to resolve a commissioning schedule conflict. After lunch, you could review an interconnection agreement with the transmission team, followed by a site visit (virtual or in-person) to verify equipment installation meets specifications.

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Review Plus Power's recent press releases and project announcements to understand their current pipeline and technology partners.
  • → Familiarize yourself with their approach to standalone BESS vs. solar-plus-storage, as this role focuses on standalone systems.
  • → Look into the specific utility interconnection requirements in regions where Plus Power operates (e.g., ERCOT, CAISO, PJM).
  • → Check out their career page and LinkedIn to understand company culture and any recent leadership changes.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a time you resolved a major commissioning issue on a substation or BESS project.
2 How do you prioritize tasks when managing multiple vendors and contractors on a tight schedule?
3 Walk us through your process for reviewing and negotiating an interconnection agreement.
4 What experience do you have with battery energy storage system commissioning, including testing battery management systems?
5 How do you stay current with evolving grid codes and standards (e.g., IEEE, NERC) for high-voltage systems?

⚠️ Common Mistakes to Avoid

  • Don't submit a generic resume—omit unrelated experience (e.g., low-voltage or residential) and emphasize utility-scale power engineering.
  • Avoid vague language like 'helped with commissioning'—use action verbs and specific metrics (e.g., 'led commissioning of 200MW substation').
  • Don't neglect to mention AutoCAD proficiency; if you're not current, take a refresher course before applying.
