Terra Works Prime Power provides a full-wrap EPC solution for solar and battery energy storage (BESS) projects, taking responsibility for early-stage project optimization, engineering coordination, procurement management, construction execution, QA/QC, commissioning, and closeout under one accountable delivery structure.
We help owners and developers refine layouts, equipment selections, constructability, schedules, budgets, and interconnection assumptions early so projects are better positioned before major capital is committed. From there, we bridge the gap between developers, utilities, engineers, suppliers, and subcontractors to turn partially developed or owner-furnished designs, equipment, and requirements into buildable, financeable projects.
The result is a practical, contractor-led EPC approach that combines technical depth, disciplined project management, and real-world construction execution to reduce owner risk and keep distributed generation and commercial-scale energy projects moving.
Our engineering team supports solar and BESS projects with coordinated discipline expertise—from site civil work through grid interconnection. We align drawings, specifications, and constructability reviews with how the project will actually be built in the field.
Grading, drainage, erosion control, access roads, stormwater management, and site layout optimization for trackers, inverters, and collection systems.
Foundation and racking design support, load analysis, pile embedment requirements, and coordination with geotechnical recommendations.
AC/DC collection, inverter placement, cable routing, grounding, and code-compliant low- and medium-voltage system design.
Substation layout, equipment specifications, protection and control interfaces, and coordination with the utility of record.
Generation tie-line planning, routing, permitting support, and constructability input for overhead and underground interconnection assets.
Whether you need a single scope or a complete turnkey build, TPP self-performs and manages the field work required to deliver utility-scale and distributed solar projects on schedule.
End-to-end EPC delivery or targeted civil scopes including mass grading, road building, stormwater controls, laydown areas, and site infrastructure.
Pile driving and verification, tracker and fixed-tilt racking assembly, module mounting, and torque/completion documentation aligned with manufacturer requirements. We are a preferred installation partner for multiple racking and tracker solutions; we work closely with equipment partners and owners to align the right system with each site.
Low-voltage DC collection, combiner and inverter installation, medium-voltage cabling, terminations, testing, and commissioning support.
Foundations, equipment setting, bus work, protection systems, and generation tie construction managed with the same QA/QC standards applied across the project site.
Specialized capabilities that improve accuracy, durability, and supply-chain control on solar and BESS projects.
High-resolution aerial surveys to build exact existing-grade surfaces for design models, quantity verification, and progress documentation.
Factory-certified adfreeze coating applied to piles for cold-region foundations where bond to permafrost or seasonally frozen soils is critical.
Procurement support and supply coordination for major equipment, including modules, inverters, trackers, and main power transformers.
Pre-cast foundation options where schedule, repeatability, or site conditions favor off-site fabrication and faster field installation.
On capped landfills or hazardous waste sites where ground penetration is limited or not permitted, we have installed fixed-tilt and tracker racking on pre-cast blocks—keeping projects buildable where conventional foundations are not an option.
Pre-cast equipment pads, substation components, and steel structure foundations reduce on-site labor while improving quality control through controlled fabrication before materials reach the project site.
