Renewable Senior Performance Engineer

Responsibilities

This position is based on a hybrid work schedule and will require in-office work 3 days per week.

Sargent & Lundy’s Consulting group is seeking a senior performance engineer with experience performing solar PV energy yield assessments on utility-scale solar projects. Candidate will specialize in solar PV and battery energy storage performance modeling while getting the opportunity to expand their expertise across CSP, wind, geothermal, simple‑ and combined‑cycle gas, RICE, and fuel cell projects—building client-facing experience with utilities, developers, IPPs, and data center developers on complex, high‑visibility consulting engagements.

This position in Sargent & Lundy’s Consulting group will require you to do the following:

• Perform solar resource assessments considering both satellite-based and ground-based data
• Analyze operational production and performance data and climatic data from solar projects
• Lead and mentor a team of performance engineers responsible for modeling, design review, and technical optimization across the solar, wind and battery energy storage projects.
• Conduct long-term solar PV energy production assessments using PVsyst and Excel-based post-processing tools.
• Primarily focus on utility-scale solar assessments but support work across all scales including residential, commercial, and industrial
• Predict energy production
• Perform uncertainty analysis to determine probabilities of exceedance (e.g., P90, P95, P99)
• Conduct statistical uncertainty analyses, clipping adjusted degradation analysis
• Participate in energy yield assessment process improvement initiatives and process validation
• Write technical due diligence reports and communicate results to clients and key stakeholders including developers and financiers
• Incorporate appropriate PV modeling assumptions and inputs into simulation
• Communicate with clients to answer technical questions with regard to solar resource and energy yield

In addition to performing PV energy yield assessments, candidate will be expected to support S&L’s independent engineering and technical due diligence services for project financing or asset acquisition of new solar projects. Common tasks include:

• Evaluating solar equipment selections / technologies
• Evaluating project execution plans from EPC contractors

• Collaborating with teammates to define project execution plans
• Monitoring project schedules and budgets
• Supporting multiple projects simultaneously while ensuring a high quality standard is met
• Interfacing with clients to understand requests and confirm successful project execution
• Familiarity with inverter/load ratio strategies, bifacial gain considerations, and soiling/loss estimation
• Preparing proposals for new business development opportunities
• Traveling occasionally to visit project locations and client offices.
