What Does a Renewable Energy Engineer Actually Do?
Renewable energy engineers design, build, and optimise power generation systems — solar farms, wind turbines, hydroelectric plants, and battery storage projects. Day-to-day work involves energy yield modelling, technical design reviews, grid connection negotiations, and supporting construction or commissioning teams on site. You'll work for energy developers, EPC contractors, consultancies, or utilities like Ørsted, RWE, or National Grid. The role typically reports to a project director or senior engineer and is split between office-based design work and site visits during project execution.

Summary
Chartered Renewable Energy Engineer with 7 years of experience in wind and solar farm design, grid integration, and energy storage. IET member with expertise in PVsyst, WindPRO, and SCADA systems.
Work Experience
Senior Renewables Engineer at EDF RenewablesApr 2022 — Present
Lead technical design for 200MW offshore wind project in the Celtic Sea from concept to consent
Conduct energy yield assessments using WindPRO and in-house wake modelling tools
Solar Engineer at VattenfallAug 2018 — Mar 2022
Designed 8 utility-scale solar farms totalling 400MW across UK and Netherlands
Performed detailed PVsyst modelling and loss assessments for due diligence reviews
Renewable Energy Engineer CVs must demonstrate technical expertise in specific renewable technologies and project delivery experience. Recruiters want to see MW capacity designed, energy yield assessments conducted, and grid connection experience.
Key Skills to Include
PVsyst, WindPRO, grid integration, SCADA systems, energy storage (BESS), project management, AutoCAD, power systems analysis, and environmental impact assessment.
Common Mistakes
Not specifying your technology focus. Wind, solar, and battery storage are different specialisms. Be clear about your specific expertise and the scale of projects you have worked on.
Formatting Tips
One to two pages. Include a Key Projects section listing MW capacity and technology type. Highlight your IET or equivalent chartership.

Top 5 Interview Questions — Renewable Energy Engineer
1Walk me through how you would conduct an energy yield assessment for a proposed solar site.
Describe the process: obtaining irradiance data from a source like SolarGIS or Meteonorm, applying PVsyst or similar modelling software, accounting for shading, soiling, and inverter losses, and producing a P50/P90 energy estimate.
2What are the main grid connection challenges for large-scale renewable projects and how do you navigate them?
Talk about grid capacity constraints, DNO/TSO queue processes, reactive power requirements, and the importance of early grid studies. Show awareness of how connection timelines can make or break a project programme.
3Tell me about a technical problem you encountered during the commissioning of a renewable energy project.
Give a specific example — an inverter fault, protection relay miscoordination, unexpected wind turbine performance. Show how you diagnosed it, who you coordinated with, and how it was resolved.
4How do you approach the technical due diligence of an energy project you're reviewing for the first time?
Cover the key workstreams: energy yield review, technical design assessment, grid connection review, contract review (EPC and O&M), and identifying key risks and mitigation measures.
5What engineering software are you proficient in and how have you used it on live projects?
Be specific: PVsyst, WindPRO, AutoCAD, ETAP, PSCAD, or Python for data analysis. Name the actual project where you used each tool — it demonstrates real application rather than just familiarity.
How to Tailor Your CV
Ørsted, RWE Renewables, Tesla Energy, and WSP Global hire renewable energy engineers broadly. Energy developers like Ørsted want engineers with wind or solar project development experience, grid connection expertise, and familiarity with offshore or onshore consenting processes. EPC contractors want hands-on construction and commissioning experience. Consultancies like WSP or Atkins value breadth — the ability to do independent technical review and write credible due diligence reports for lenders and investors is particularly valued.
