Complete civil packages for battery energy storage near Rotterdam, 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 Rotterdam in Schenectady County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Rotterdam holds the GE Vernova campus, the Rotterdam industrial corridor along NY Route 5S, the New York State Thruway interchange and the Rotterdam to Bear Swamp 230 kV transmission line. The Form Energy iron air proposal would occupy just under ten acres on the GE Vernova campus. Town siting is constrained by the Great Flats Aquifer, which sits under much of the developable north end and was the central objection raised against earlier lithium ion proposals, so containment grading and groundwater protection are the governing civil issues on any pad here.

The county straddles the Mohawk River. The valley floor through Schenectady, Rotterdam and Glenville is the Great Flats, a thick sand and gravel outwash and alluvial plain that also forms the Great Flats Aquifer, the drinking water source for the area. Soils on the flats are sandy and gravelly with rapid permeability and a shallow water table close to the river, with Schenectady and Teel type alluvial soils on the floodplain benches. North of Glenville and south of Rotterdam the ground rises onto till covered uplands underlain by shale and sandstone, with denser, stonier soils and locally shallow bedrock. Duanesburg in the southwest sits on the plateau margin with fragipan soils that perch water and drain slowly. Design frost depth is commonly taken at about 48 inches. The dominant engineering fact in the county is groundwater: the aquifer is shallow, permeable and legally protected.
On the Great Flats the earthwork itself is easy. Outwash sand and gravel excavate cleanly, compact to high density and make good structural fill, so pad subgrades and access roads are usually straightforward. The constraints are groundwater and aquifer protection. Shallow water table means foundation excavations and deeper trenches will need dewatering and a discharge plan, and any spoil stockpile or fueling area needs containment. Because the aquifer is permeable, stormwater design tends to run toward lined or containment based practices around the enclosure footprint rather than open infiltration, even though the soils would otherwise infiltrate well. Expect spill containment grading, curbing and impervious pad areas under transformers. On the surrounding till uplands the picture reverses: stony subgrade, slow draining fragipan soils and locally shallow rock drive undercut, drainage blanket and hammer work.

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 Rotterdam Town Board, acting as SEQR lead agency, adopted a zoning amendment regulating battery energy storage systems, with the negative declaration published in the DEC Environmental Notice Bulletin on December 31, 2025; a developer has described the resulting code as effectively a ban on commercial systems. Glenville adopted a 120 day moratorium in June 2025 while it drafts code, and Duanesburg has restricted utility scale systems.

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.
