Overview

The Interconnection & PV/BESS Design Engineer supports utility‑scale photovoltaic (PV) and battery energy storage system (BESS) projects from early development through EPC execution. This role serves as the developer’s technical representative through ~30% design and as an owner’s design steward thereafter, ensuring design intent, performance assumptions, and interconnection requirements are consistently carried forward into EPC‑led detailed engineering.

Key Responsibilities

• Owns developer‑level PV and BESS layouts, single‑line diagrams, through all interconnection phases and 30% design.
• Acts as the design authority for early‑stage and pre‑EPC design decisions; accountable for technical completeness and accuracy at handoff.
• Represents owner design intent during EPC execution, ensuring performance, constructability, and interconnection assumptions are preserved.
• Responsible for identifying design risks, performance impacts, and constructability issues and elevating them with clear recommendations.

Early Development & Interconnection

• Develops preliminary PV and BESS site layouts and electrical single‑line diagrams using PVCase and AutoCAD.
• Integrates utility, land, environmental, and permitting constraints into early design packages.
• Supports utility interconnection applications and studies by supplying layouts, system parameters, and modeling assumptions.
• Coordinates with utilities, consultants, and internal stakeholders to align interconnection requirements with project design.

Performance Modeling & Technical Analysis

• Builds and maintains SolarFarmer and/or PVsyst performance models through all design phases.
• Establishes and documents modeling assumptions, including losses, degradation, clipping strategy, and curtailment considerations.
• Supports Independent Engineer reviews by providing transparent, defensible modeling inputs and documentation.
• Ensures performance assumptions align with long‑term asset ownership and financing requirements.

Pre‑EPC Design Development (to ~30%)

• Advances layouts and electrical design content to support EPC pricing, constructability review, and risk evaluation.
• Ensures alignment between interconnection requirements and plant‑level electrical design.
• Documents design intent, constraints, and open items prior to EPC handoff.

EPC Transition & Design Oversight

• Participates in EPC kickoff meetings as the owner’s design representative.
• Communicates design assumptions, performance drivers, and constraints to EPC partners.
• Reviews EPC‑issued design packages (IFC and revisions) for conformance with approved layouts, performance assumptions, and interconnection commitments.

M&A Development and Oversight

• Support M&A activities by performing technical due diligence to assess facility, site, and infrastructure viability, risks, and capital requirements.
• Develop conceptual layouts and engineering models (up to ~30% design) for acquired or target assets to validate capacity, footprint, and redevelopment or expansion scenarios.
• Conduct preliminary building, fire, zoning, and life‑safety code reviews; identify compliance gaps and develop code enforcement and mitigation strategies in coordination with AHJs.
• Collaborate with corporate development, finance, and operations teams to translate technical findings into acquisition recommendations and post‑acquisitio
