How to Apply for Grid Connection Engineer m/f/d (Solar PV – Construction Focus Only)

at Greencells Group

🏢 About Greencells Group

Greencells Group is a global leader in solar power solutions with a mission to build a cleaner future, operating across multiple continents with a strong track record in utility-scale solar projects. Their German location positions them at the heart of Europe's renewable energy transition, offering exposure to international projects while contributing to Germany's ambitious solar expansion goals. Working here means joining a company that combines technical expertise with environmental impact on a global scale.

About This Role

This Grid Connection Engineer role focuses exclusively on the construction phase of solar PV projects, ensuring all grid connection requirements are properly implemented during build-out. You'll be the technical bridge between DNOs/ICPs and construction teams, validating designs, overseeing HV/MV installations, and ensuring compliance with UK standards like G99/G100. Your work directly enables solar farms to connect to the grid and start generating clean energy.

💡 A Day in the Life

A typical day involves reviewing construction progress against grid connection milestones, validating that HV cable installations and substation works align with approved designs, and coordinating with DNO representatives for upcoming inspections. You might spend mornings on-site checking protection scheme implementations and afternoons reviewing as-built documentation or attending DNO meetings to ensure readiness for energisation.

🎯 Who Greencells Group Is Looking For

  • Electrical engineering graduate with hands-on construction experience on utility-scale solar PV or HV substations in the UK market
  • Demonstrates specific knowledge of DNO/ICP processes, G99/G100 requirements, protection coordination, and HV/LV installation standards
  • Proven ability to interpret technical drawings, SLDs, and protection schemes while validating as-built documentation against approved designs
  • Experience attending DNO/ICP meetings, site inspections, and witness tests with strong documentation and compliance focus

📝 Tips for Applying to Greencells Group

1

Highlight specific UK grid connection projects you've worked on, mentioning DNOs/ICPs by name and detailing your construction-phase involvement

2

Quantify your experience with utility-scale solar PV (e.g., 'oversaw grid connection for 50MW solar farm in Yorkshire') and HV substation construction

3

Demonstrate your G99/G100 expertise by describing how you've ensured compliance during construction, not just design phases

4

Tailor your resume to show construction oversight experience - not just design - with terms like 'method statements,' 'RAMS review,' and 'energisation readiness'

5

Research Greencells' specific projects in Germany/UK and mention how your grid connection experience aligns with their portfolio

✉️ What to Emphasize in Your Cover Letter

['Your hands-on construction experience with UK grid connections, specifically during build-out phases rather than just design', 'Examples of successfully coordinating between DNOs/ICPs and construction teams to meet energisation deadlines', 'Technical proficiency with protection schemes, HV/MV installations, and ensuring as-built documentation matches approved designs', "Why you're drawn to Greencells' global solar mission and how your UK grid expertise transfers to their German-based operations"]

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Greencells' specific solar projects in Germany and the UK - understand their scale, locations, and grid connection challenges
  • → German grid connection standards (like VDE-AR-N 4105) compared to UK's G99/G100 to show awareness of regulatory differences
  • → Recent news about Greencells' expansion or project completions to demonstrate genuine interest in their work
  • → Germany's solar energy targets and grid integration challenges to contextualize the role's importance

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk us through a specific grid connection project where you coordinated with a DNO during construction - what challenges arose and how did you resolve them?
2 How do you ensure G99/G100 requirements are properly implemented during construction, not just in design? Give a concrete example.
3 Describe your process for reviewing method statements and RAMS for grid-related works - what red flags do you look for?
4 How do you handle discrepancies between as-built conditions and approved connection designs during construction?
5 Given Greencells operates globally, how would your UK grid connection experience apply to projects in Germany or other markets?

⚠️ Common Mistakes to Avoid

  • Focusing only on design experience without emphasizing construction-phase involvement - this role is construction-focused
  • Being vague about UK-specific grid requirements - use precise terms like G99, DNO processes, and protection coordination
  • Applying with generic renewable energy experience without highlighting specific utility-scale solar PV and HV substation construction
