Complete civil packages for battery energy storage near Central Square, 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 Central Square in Oswego County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Central Square sits at the Interstate 81 exit 32 interchange with Route 11 and Route 49, which makes it the best heavy haul position in southern Oswego County. It is the commercial center of the Town of Hastings and holds served industrial and commercial ground along both routes. Soils are lake plain sand with Sodus and Ira till inland and muck in the closed depressions toward Oneida Lake. The water table is shallow across much of the village. For storage siting the advantage is access and distribution capacity; the limits are wetland mapping south toward Big Bay and the shallow groundwater that drives trench dewatering and buoyancy checks on any below grade structure.

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.
Oswego County is dominated by the Ontario lake plain and by sand and gravel deltas laid down by glacial Lake Iroquois. Along the lake and the lower Oswego and Salmon River valleys the soils are deep sands: Colosse, Colonie, Elnora, Granby and Naumburg, with Naumburg and Granby complexes mapped across large areas. These drain quickly but sit over a high water table, and Naumburg in particular carries a seasonal water table within a foot of the surface. Inland toward Mexico, Parish and Hastings the ground shifts to Sodus, Ira and Minoa soils on drumlin and till plain, with dense till and water perched above it. Lamson and Canandaigua silt loams occupy the flats. Carlisle and Palms muck fill the closed depressions and the wetland complexes around Oneida Lake at Constantia and Cleveland. Bedrock is Oswego Sandstone and Pulaski shale, generally deep under the lake plain but closer to grade on the Tug Hill flank near Parish and Redfield. The county carries the heaviest lake effect snow load in the region and a design frost depth commonly taken at 48 inches.
Deep sand is the defining condition. It excavates fast and needs no rock budget, but it will not hold a trench wall, so shoring or laid back slopes are required for every duct bank and every foundation excavation, and dewatering is a standing item wherever the water table sits within a few feet of grade. Sand subgrades also lose capacity when saturated, so enclosure pads generally need a geogrid reinforced stone section rather than a thin base over native material. Where the ground shifts to Sodus and Ira till the problem inverts: water perches on the dense layer, spring work is limited, and access roads need underdrain. Muck in the Oneida Lake and Salmon River wetland complexes has to be excavated and replaced, not bridged. Erosion control on sand demands close spacing of practices and rapid stabilization, because these soils move under sheet flow. Snow load and a long winter shutdown window compress the season, which puts a premium on stabilizing pads and roads early.

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 City of Oswego has a utility scale battery storage moratorium with no stated expiration, and the Town of Schroeppel has a solar plus storage moratorium extended to February 2027, both per the Carina Energy moratorium database. Other Oswego 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.
