Energy

Roncelli provides full-service Engineering, Procurement, and Construction, or EPC, delivery for utility-scale renewable energy projects. Our EPC model brings engineering development, procurement strategy, construction execution, and commissioning under one accountable structure, creating alignment from early concept through system turnover.

Renewable energy projects require coordinated integration across every discipline. Grid interconnection, permitting, long-lead procurement, supply chain management, site logistics, construction sequencing, and field execution must work together as one continuous process. Roncelli manages these elements with discipline and clarity, helping clients anticipate risk, protect schedules, and maintain cost certainty.

Our energy work includes utility-scale solar arrays, battery energy storage systems, and the critical infrastructure that supports them. By managing engineering, procurement, and construction as a single effort, we streamline decision-making, strengthen cost control, and maintain schedule integrity across large, complex renewable energy programs.

We build energy facilities that support system performance, resilience, and long-term value for our clients and the communities they serve.
