Complete civil packages for battery energy storage near Horseheads, 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 Horseheads in Chemung County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Horseheads holds the county's largest concentration of industrial and warehouse land, including the former Westinghouse complex and the extensive rail served parcels along the Route 17 and Interstate 86 interchange with Route 14. Heavy haul access is unrestricted from Interstate 86 and Route 17. NYSEG substations serving the village and town include Ridge Rd, Tuttle Place and Yawger Rd. The Newtown Creek and Chemung valley outwash under most of the industrial ground is deep gravelly loam, which supports high bearing pads and straightforward trenching, while ground rising north toward Big Flats transitions into Volusia and Mardin till.

Chemung County is glaciated Appalachian Plateau cut by the broad Chemung River valley, which runs east to west through Elmira and Big Flats. Upland series are dominated by Volusia, Lordstown and Mardin, with Arnot appearing on steep shoulders where the soil is shallow, commonly less than 20 inches over shale and siltstone bedrock, and Chippewa in poorly drained till depressions. The valley floor is one of the widest outwash plains in the Southern Tier and carries Howard and Chenango gravelly loams together with Unadilla silt loam and Tioga soils on the floodplain, all deep and generally well to excessively drained. Hudson soils, formed in lacustrine silt and clay, appear locally and behave very differently from the outwash around them. Relief from the valley floor near 850 feet to the ridge crests above 1,800 feet is abrupt. Design frost depth is roughly 42 inches.
The Chemung valley outwash plain is close to ideal ground for battery enclosure pads. Howard and Chenango subgrades are deep and granular, support high bearing values with modest proof rolling, drain readily, and allow trenching for cable and grounding without rock. The trade is a shallow water table in places and floodplain constraints along the Chemung River, both of which drive foundation excavation dewatering and limit where fill can be placed. Where a site sits on Hudson lacustrine silt and clay the behavior reverses, and the pad should be designed with undercut, geogrid and an imported structural section. Uplands south of Southport and north toward Horseheads bring Volusia fragipan and Arnot shallow shale into play, so those parcels should be priced with curtain drains, detention based stormwater and rock excavation for trenching. Site work here is generally workable from early April into December.

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 Southport carries an active utility scale battery storage moratorium, adopted by resolution in December 2024 as a six month moratorium on commercial solar energy systems and commercial energy storage systems and since carried forward. The Town of Elmira considered a moratorium in connection with the Carson Power proposal and the motion did not pass.
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.
