Complete civil packages for battery energy storage near Elbridge, 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 Elbridge in Onondaga County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Elbridge holds the Elbridge and Jordan substations and the Elbridge to Geres Lock 115 kV lines, which carried a 260 MW storage filing from Renew Development before it was withdrawn from the NYISO cluster. A 5,000 kW and 20,000 kWh retail storage project was also filed at Wheeler Road. The town sits on the Seneca River and the state canal corridor with the Route 5 and Route 31 crossing at Jordan, and Route 690 is a short run east. Soils are drumlin till with outwash gravel along the river and muck in the closed depressions. The canal corridor and river floodplain drive most of the permitting on sites here.

Onondaga County spans three physiographic settings. North of the Seneca River the ground is Ontario lake plain and drumlin field, with Honeoye and Lima silt loams on the drumlin crests, Kendaia and Lyons soils in the swales, and Palmyra and Howard gravelly loams on the outwash terraces near Baldwinsville and Clay. The Cicero Swamp and the flats east of Clay carry Carlisle and Palms muck over lacustrine silt, with a water table at or near the surface for much of the year. The Syracuse core and the Onondaga Lake margin sit on lacustrine clay, artificial fill and the Solvay waste beds. South of Route 20 the land rises onto the Allegheny Plateau, where Lordstown channery silt loam sits over shallow Hamilton Group siltstone and shale, often less than three feet to refusal, and where Volusia, Mardin and Erie soils carry a dense fragipan that perches water within two feet of grade. The Tully valley holds deep glaciolacustrine silt and clay with documented mudboil and subsidence activity. Design frost depth is commonly taken at 42 to 48 inches, and drainage runs to Onondaga Lake, the Seneca River and the Tioughnioga.
Pad subgrades differ block by block. On the drumlin uplands, Honeoye and Lima silt loams compact well when dry but pump badly in spring, so enclosure pads generally need undercut, geotextile separation and imported crusher run rather than in place material. Outwash terraces at Clay and Baldwinsville give free draining gravel and the fastest foundation excavation, with the tradeoff that infiltration practices must be sized against groundwater. Muck pockets in the Cicero Swamp belt require full excavation and replacement or surcharge, and trench boxes must account for running sand below the peat. Fragipan soils south of Route 20 hold water above the pan, so trenches fill and access roads rut unless underdrains and a thicker stone section are provided. Shallow siltstone on the plateau means hammering or blasting for duct banks and transformer footings, and rock should be priced by the linear foot of trench rather than by the cubic yard of mass excavation. Stormwater on these sites falls under SPDES general permit coverage with a full SWPPP and a qualified inspector.

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 Clay adopted Chapter 209, its Battery Energy Storage System Law, on June 30, 2026, following a six month moratorium enacted in April 2026, and the Town of Cicero maintains its own Chapter 209 requiring site plan approval and a special use permit for Tier 2 and Tier 3 systems. The Carina Energy moratorium database lists active restrictions in Camillus to March 2027, Marcellus to May 2027, Spafford to June 2027 and Lysander to December 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.
