Complete civil packages for battery energy storage near Coxsackie, 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 Coxsackie in Greene County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Coxsackie is at Interstate 87 Thruway exit 21B with Route 9W and an industrial and correctional facility cluster near the interchange, plus CSX river line frontage, which gives it good highway and rail access. BayWa announced a battery storage facility in the village and dropped it roughly four months later, citing wetlands on the site and the need for a new substation. The village has since advanced a local law that would prohibit utility scale battery systems outright. Lowland ground here is lake clay and terrace deposit with extensive regulated wetland in the flats.

Greene County splits sharply at the Catskill escarpment. East of it, the Hudson lowland from Coxsackie through Catskill is Glacial Lake Albany bottom and river terrace: deep, calcareous, clayey glaciolacustrine soils of the Hudson, Vergennes, Rhinebeck and Kingsbury type with very slow permeability, high shrink and swell and seasonal high water, interrupted by stratified drift terraces and by Tioga and Wayland alluvium along the Catskill and Coxsackie creeks. Shale and limestone bedrock lies beneath, generally at moderate depth in the lowland but shallow on the low ridges. West of Route 32 the land climbs abruptly into Catskill sandstone, siltstone and conglomerate, where Arnot soils sit on bedrock at 10 to 20 inches and Lackawanna, Wellsboro and Morris carry a dense fragipan starting between roughly 17 and 36 inches. The 1993 Soil Survey of Greene County is the printed reference and the county conservation district hosts digital copies. Frost design depth is commonly taken at 48 inches subject to the building department.
Stay east of the escarpment and the earthwork is manageable. River terrace stratified drift gives good bearing and straightforward trenching, which is why the flat ground along Route 9W and the Thruway corridor keeps attracting proposals. Step onto the lake clays and the picture changes: very slow permeability rules out infiltration, high erodibility drives the erosion and sediment control scope, and the subgrade will not carry traffic wet, so the stone haul road network has to precede general earthwork. The withdrawn Coxsackie project is a useful warning on the other constraint, which is wetland. The lowland flats hold extensive federal and state wetland, and a layout that looks clean on a tax map can lose its usable area once a delineation is done, so delineation should precede pad layout rather than follow it. West of the escarpment, shallow Arnot sandstone and the Lackawanna fragipan bring rock excavation and perched water, and the grades make access road construction the dominant cost.

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 Town of Athens carries a battery energy storage facilities moratorium covering all systems, first enacted in March 2024 and extended every six months since while the town completes zoning updates. The Village of Coxsackie has advanced a local law that would prohibit utility scale battery systems outright. Greene County Planning and Economic Development maintains a public page on battery energy storage for member municipalities.
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.
