How to Apply for HV and Transmission Interconnection Engineer

at Intersect Power

🏢 About Intersect Power

Intersect Power is a mission-driven team focused on scalable low-carbon solutions for energy markets, and as of December 2025, it's set to be acquired by Google to accelerate data center and clean energy infrastructure. This unique partnership offers the stability and resources of a tech giant while maintaining the agility and culture of a startup, making it an exciting place to drive real climate impact.

About This Role

As an HV and Transmission Interconnection Engineer, you'll lead the technical design and grid interconnection of high-voltage systems for large-scale clean energy projects. Your work directly enables the rapid deployment of renewable generation and data center capacity, supporting Google's ambitious energy and infrastructure goals.

💡 A Day in the Life

A typical day might start with reviewing interconnection study results from an ISO, then collaborating with the development team to adjust project layouts. After lunch, you could run power system simulations to assess a new substation design, followed by a call with a utility to negotiate a generator interconnection agreement. The day ends with documenting technical specifications for a 230 kV transmission line.

Practice questions for this role

🎯 Who Intersect Power Is Looking For

  • Deep expertise in high-voltage (HV) transmission system design, including substation, line, and protection schemes, with hands-on experience in utility-scale renewable projects (solar, wind, BESS).
  • Proven track record of managing interconnection applications (e.g., with ISOs/RTOs like CAISO, ERCOT, PJM) and navigating complex grid interconnection processes.
  • Strong analytical skills using power system modeling tools (e.g., PSS/E, PSCAD, ETAP) to assess grid impact and ensure compliance with NERC, FERC, and local codes.
  • Ability to collaborate cross-functionally with development, construction, and regulatory teams, and communicate technical concepts to non-technical stakeholders.

📝 Tips for Applying to Intersect Power

1

Highlight specific projects where you led interconnection from initial application to commercial operation, including any challenges overcome with ISOs/RTOs.

2

Quantify your impact: e.g., 'Reduced interconnection timeline by 20% through proactive coordination' or 'Designed a 230 kV substation for a 200 MW solar farm that achieved 99.9% availability.'

3

Show familiarity with Google's energy goals and how Intersect's role fits into powering data centers with clean energy.

4

Tailor your resume to emphasize HV engineering, not just general electrical engineering; include specific voltage levels (e.g., 138 kV, 230 kV, 500 kV) and relevant software.

5

Mention any experience with energy storage or hybrid plants, as Intersect focuses on innovative low-carbon solutions.

✉️ What to Emphasize in Your Cover Letter

["Express passion for the company's mission to decarbonize energy and enable data center growth, aligning with Google's acquisition.", 'Describe a specific interconnection challenge you solved (e.g., managing a long queue or mitigating grid upgrade costs).', 'Demonstrate understanding of the unique opportunity at the intersection of clean energy and tech infrastructure.', 'Show eagerness to work in a fast-paced, remote environment with cross-functional teams.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Study Intersect Power's current project portfolio (solar, storage, green hydrogen) and their interconnection statuses.
  • → Understand the terms of Google's acquisition and how it impacts Intersect's operations and growth plans.
  • → Review the interconnection requirements in key ISOs/RTOs where Intersect operates (e.g., CAISO, ERCOT, WECC).
  • → Look into recent news about data center energy demands and how Intersect/Google plans to address them.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk me through a time you managed a complex interconnection process from start to finish.
2 How do you approach modeling and analyzing grid impacts for a large-scale renewable project?
3 Describe a situation where you had to negotiate with a utility or ISO to resolve a technical issue.
4 How do you stay current with changing interconnection standards (e.g., NERC, FERC, IEEE)?
5 Given Intersect's focus on 'scalable low-carbon solutions,' how would you design a transmission system for a hybrid solar-plus-storage plant?

⚠️ Common Mistakes to Avoid

  • Submitting a generic cover letter that doesn't mention Google acquisition or Intersect's specific mission.
  • Overlooking the remote nature of the role; emphasize your self-motivation and remote collaboration experience.
  • Failing to provide concrete examples of interconnection work; vague claims like 'familiar with grid codes' won't stand out.
