WHY ILLUMINE-i FOR EPCs
"10 years of EPC partnerships. We understand your timelines and margins — and we engineer for construction, not just compliance."
What We Solve For You
EPCs and developers live in a world of tight timelines, thin margins, and unforgiving AHJs. A permit rejection or a revision cycle costs real money. An interconnection package that doesn't meet utility requirements delays a project by months. We've been engineering alongside EPCs long enough to know exactly what causes these problems — and how to prevent them.
Our packages are formatted for the recipients who matter to you: AHJ plan checkers, interconnection engineers, building inspectors. We produce deliverables that move forward the first time.
What We Provide
01
Preliminary Engineering
Site assessment, feasibility, conceptual design, and rough cost estimates for go/no-go decisions. Fast, accurate, decision-ready.
02
Detailed Engineering
Construction-ready permit packages, SLDs, structural calculations, interconnection applications. Formatted for first-time AHJ approval.
03
Interconnection Support
Utility application preparation, open comment resolution, and interconnection study support. We close open items in the format utilities want to receive them.
04
Project Management
Coordination, scheduling, RFI management, and quality control through construction. Includes Thrive portal for full schedule visibility.
05
BESS & Substation Integration
When the project scope extends beyond PV — BESS electrical design, substation interface, civil coordination — we cover the full stack.
PRODUCTS
Why Teams Come Back
First-time approval focus
We build packages for the reviewer, not just the spec. Fewer revision cycles means faster COD and lower cost of engineering.
Construction-aware design
Our engineers know what gets built and what causes field RFIs. Constructability is in the design, not added at the end.
Volume capability
We work with EPCs running concurrent projects across multiple markets. Our process scales without quality degrading.
Flexible integration
We operate as an extension of your engineering team — in your workflow, using your naming conventions, on your schedule.
