Complete civil packages for battery energy storage in Oneida County, New York: pad subgrade and mass grading, foundation excavation, access and crane pads, collection trenching, ductbank, SWPPP, and substation civil.
Backwell is a civil site work general contractor serving battery energy storage developers and EPCs building in Oneida County, New York. We contract the complete civil package under one agreement, with Backwell superintendents and lead operators on site.
Oneida County is the transmission crossroads of upstate New York and the load center of the Mohawk Valley. The Marcy and Edic 345 kV substations anchor the eastern end of National Grid's Smart Path Connect rebuild, which together with NYPA's Smart Path work formed close to 200 miles of upgraded 345 kV between Clinton and Oneida counties. On the load side, National Grid's Oneida County Transmission Upgrade is scoped to serve Griffis Business and Technology Park in Rome, Marcy Nanocenter and Schuyler Business Park, the three sites driving semiconductor supply chain growth. Storage has run into local law faster than it has run into the grid. The Rome Common Council adopted Ordinance 9884 on August 26, 2026 prohibiting battery energy storage systems in the city, which ended DLD Energy's proposal at 600 Canal Street. The City of Utica adopted a six month moratorium on August 27, 2025 and has draft siting regulations before its Planning Board. For civil contractors the near term volume is substation and solar sitework, with enclosure pads following wherever zoning reopens.

Project details come from public filings and reporting and are listed to show where the work is. Backwell is not affiliated with these projects or their developers.
The county spans three settings. The Mohawk River corridor from Rome through Utica is a glacial lake and alluvial plain carrying Hudson, Rhinebeck and Madalin silts and clays with Ilion soils in the depressions, all with seasonal high water tables near the surface and slow permeability. North and west toward Tug Hill the till uplands carry Camroden and Westbury soils formed in dense shale and siltstone till, both with fragipans that perch water within one to two feet of grade. South of the Mohawk the plateau margin carries Palatine, Mohawk and Nellis soils formed in calcareous and dark shale till, with shale bedrock commonly between twenty and forty inches in the Palatine series. Gravel terraces along the Mohawk River and along Oriskany and Sauquoit Creeks carry Howard outwash, the driest and best draining ground in the county. The northeast corner at Boonville and Forestport lies inside the Adirondack Park, where sandy Adams and Colton outwash and Tug Hill snowfall govern the season.
Pad subgrade in the valley is the controlling problem. Lacustrine silt and clay and the fragipan tills drain slowly, soften under construction traffic and will not carry enclosure slabs, transformer pads or crane mats without undercut, geotextile separation and imported structural fill. Collection and auxiliary trenching in the Mohawk floodplain should assume wet excavation, dewatering and trench box work. On the shale uplands the opposite applies: Palatine and Mohawk profiles put competent shale within normal excavator reach, so foundation excavation, cable trench and grounding grid installation should carry rock provisions and probable hammer or rock trencher production. The Howard gravel terraces along the Mohawk and Oriskany Creek give the best pad platforms and the shortest access road sections. Stormwater work should assume coverage under the state construction general permit with heavy sediment loading off silt subgrades, and frost protection at footings and buried conduit commonly runs to forty eight inches or more.
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. The City of Rome prohibited battery energy storage systems by Ordinance 9884 adopted August 26, 2026. The City of Utica adopted a six month moratorium on August 27, 2025 and its Planning Board is reviewing draft regulations that would allow the use in the Industrial and Industrial Mixed Use districts by special use permit with site plan review. The Town of Forestport has adopted a ban and the Town of Florence moratorium was listed as under review as of September 2026.
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.
