Self-performing EPC for solar, wind, and battery storage. Engineering, procurement, and construction from foundations to long-term operations and maintenance, across North America.
Willert Construction self-performs across the renewable energy stack. We engineer, procure, and build utility-scale, distributed-generation, and commercial solar, along with battery energy storage and balance-of-plant wind. Self-performing the civil, mechanical, and electrical scopes keeps quality, schedule, and safety under one accountable team.
From Safe Harbor and PTC qualification work through pile installation, module and tracker construction, substation and transmission foundations, and full commissioning, we deliver the whole project. When the plant is running, our operations and maintenance, repowering, and decommissioning services keep it producing for the long haul.
Nine self-performed disciplines that carry a renewable energy project from the first pile to long-term operations.
Civil, structural, and electrical engineering and design for utility-scale, distributed-generation, and commercial solar.
Equipment and material procurement and storage, plus Safe Harbor and PTC qualification work to protect tax credits.
Driven and screw-pile installation, pile load testing, and reporting for solar racking and tracker foundations.
Self-performed civil, mechanical, and electrical construction for fixed-tilt, single-axis tracker, rooftop, and floating solar.
Battery storage facility construction and foundations for utility-scale and commercial energy storage.
Balance-of-plant wind: turnkey turbine foundations, WTG assembly and erection, collection-system trenching, grout, and bolt tensioning.
Substation, switchyard, and transmission-line foundations, plus operations and maintenance building foundations.
Operations and maintenance, module replacement, storm and wind damage repair, repowering, and full decommissioning.
Site maintenance, mowing or sheep grazing, pollinator seeding, and tracker, pile, and fixed-tilt remediation.
One accountable team from engineering through operations, so your schedule, budget, and safety stay under control.
