Complete civil packages for battery energy storage near Port Byron, NY: pad subgrade and mass grading, foundation excavation, access and crane pads, collection trenching, ductbank, SWPPP, and substation civil.
Backwell contracts complete civil site work packages for battery energy storage developers and EPCs building near Port Byron in Cayuga County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Port Byron sits on the Erie Canal and the Seneca River in the Town of Mentz, at Thruway interchange 40 and the Route 31 and Route 38 junction. The village lies at the edge of the Montezuma wetland complex, so muck depth and a surface water table are the dominant subsurface conditions on the north and east sides. The Town of Mentz has an active utility scale battery storage moratorium listed as of 2026. Heavy haul access is excellent from the Thruway. Any pad in this ground requires full muck excavation and replacement or a surcharge program, trenching requires continuous dewatering, and access roads need geotextile separation with a heavy stone section to avoid pumping.

Cayuga County is drumlin country. North of Auburn the ground is one of the densest drumlin fields in North America, with Honeoye, Lima and Ontario silt loams on the drumlin crests and flanks and Kendaia, Lyons and Canandaigua soils in the poorly drained swales between them. The Montezuma marshes at the north end of Cayuga Lake, straddling the Seneca River and the towns of Montezuma, Mentz and Aurelius, hold extensive Carlisle, Palms and Edwards muck over marl and lacustrine clay, with a water table at the surface. Cayuga Lake divides the county, and the east shore from Aurelius south through Springport, Scipio and Ledyard rises in benches of Ovid, Cazenovia and Angola soils over Ludlowville and Onondaga shale and limestone, which outcrop in the lake gorges. South toward Moravia and Locke the land climbs onto the plateau with Lordstown, Mardin and Volusia soils over shallow siltstone. Bedrock is close to grade on the lake benches and the southern uplands, and deep under the drumlin field and the marshes.
The drumlin field is the defining civil condition in the north. Drumlin crests give firm, well drained subgrade, but the swales between them hold Kendaia and Lyons soils with water near the surface, so a pad laid out across two drumlins will need different treatment at each end and the access road between them will need underdrain and a heavy stone section. Farm drainage tile is everywhere in this ground and has to be located, intercepted and reconnected. In the Montezuma marsh belt, muck depths make pad construction impractical without full excavation and replacement or long term surcharge, and trenching there requires continuous dewatering and shoring in running silt. On the lake benches and the southern plateau, shale and limestone sit within a few feet of grade, so trench rock and footing rock are standing items. Any site inside the Owasco Lake or Cayuga Lake watershed carries additional stormwater and phosphorus scrutiny because both are public water supplies.

Concrete is placed by our subcontractor partners under the same contract, so the foundations follow the earthwork without a separate award. We price the civil package as one scope under one contract, which gives the EPC a single point of responsibility for the civil critical path instead of managing separate clearing, earthwork, and underground subcontracts.
Battery storage in New York is governed by Section 1207 of the 2025 Fire Code of New York State, which the State Fire Prevention and Building Code Council adopted on July 25, 2025 with an effective date of December 31, 2025. Section 1207 carries material based on the 2023 edition of NFPA 855 and renumbers what the 2020 code placed at Section 1206. Systems must be listed to UL 9540. Large scale fire testing under UL 9540A, reported to and approved by the fire code official, is what permits reduced separation distances and quantities above the table limits, and a hazard mitigation analysis is required to exceed the maximum allowable quantity. Outdoor installations carry a ten foot clearance to lot lines, public ways, buildings, stored combustibles, and other exposure hazards, with ten feet of combustible vegetation cleared on each side. New York added a mandatory peer review at Section 1207.12 for systems above the Table 1207.5 quantities, covering the site plan, the emergency operations plan, and the UL 9540A report. Those provisions fix pad layout and access road geometry before any earthwork is priced.
Battery storage siting in New York runs on the Fire Code of New York State, which adopts the International Fire Code provisions for stationary energy storage, together with NFPA 855 and the UL 9540A test reporting the authority having jurisdiction will ask for. The civil consequences are set early and they are ours to build.
We build to the approved civil drawings and the fire code commentary that comes with the permit. We do not stamp the design.
Local law. As of September 2026 the Carina Energy moratorium database lists an active utility scale battery storage moratorium in the Town of Mentz and a moratorium under review in the Town of Victory. Other Cayuga County towns are working from their own zoning and from the NYSERDA model battery energy storage law.
Backwell superintendents, project managers, and lead operators run every site. We mobilize company equipment for the core scope and scale each project with leased production fleets, qualified regional subcontractors, and agency-placed field staff, all under Backwell supervision and a single contract.
Contractor licensing. New York does not issue a statewide general contractor license for commercial construction. Licensing is handled locally, so individual cities, towns, and counties may require contractor registration or a local license, and a few trades are licensed at the state level, including asbestos handling and crane operation. Separately, contractors and subcontractors performing public work, and work covered by Article 8 of the Labor Law, must be registered with the New York State Department of Labor under its statewide contractor registry, which took effect December 30, 2024. Owners, EPCs, and integrators on battery storage projects will typically ask for that DOL registration number along with insurance and, where required, bonding.
Construction stormwater. SPDES General Permit for Stormwater Discharges from Construction Activity, permit number GP-0-25-001, issued by the New York State Department of Environmental Conservation. It took effect January 29, 2025, replacing GP-0-20-001, and runs through January 28, 2030. Coverage is triggered at one acre of soil disturbance, or less if part of a larger common plan, and requires a Notice of Intent plus a SWPPP prepared and implemented under the DEC design manual. Coverage under the prior permit did not carry over automatically, so active sites had to refile. Backwell carries the SWPPP scope, installs and maintains the controls, keeps the inspection log, and closes the permit out with final stabilization.
Prevailing wage. Standalone battery storage sits outside New York Labor Law Section 224-d. That section applies to a covered renewable energy system as defined in Public Service Law Section 66-p, and that definition lists generating technologies only, so energy storage is not included and Section 224-d contains no storage clause. Prevailing wage still reaches many storage projects by other routes. Labor Law Section 224-a expressly excludes an energy storage system with a capacity equal to or under five megawatts alternating current, which means a larger storage system on a privately contracted project that meets the public funds and cost tests can be covered. The Public Service Commission order of June 20, 2024 establishing the updated energy storage goal states that projects of one megawatt alternating current and larger will be subject to prevailing wage requirements, so incentivized projects carry it as a program condition rather than by statute. Storage co-located with a covered renewable generator follows that generator. Separately, contractors and subcontractors performing public work, and work covered by Article 8 of the Labor Law, must be registered with the New York State Department of Labor under the statewide contractor registry effective December 30, 2024. The applicable trigger should be confirmed project by project. Backwell produces certified payroll, pays the applicable wage determination, and supports apprenticeship labor-hour compliance.
