## Contract boundary

Eiffage Énergie Systèmes delivers electrical, automation and energy infrastructure packages. It may lead a group consortium or act through a JV or subcontract; client, technology-supplier and long-term operator roles are distinct.

## Project follow-through

Connection capacity, generation, battery power and storage duration are different measures. Final acceptance, permits and commercial-operation dates should be verified separately from targets.
