Complete civil packages for battery energy storage near Delhi, 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 Delhi in Delaware County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Delhi is the Delaware County seat and the location of the SUNY Delhi solar and energy storage project, 2 MW of ground mounted storage paired solar on 18 acres of campus owned land on Arbor Hill Road next to a Delaware County Electric Cooperative substation, developed with the New York Power Authority. Route 10 and Route 28 serve the village along the West Branch of the Delaware River. NYSEG substations in the area include Delhi and Axtell Rd. Buildable ground sits on the valley terrace, since the surrounding slopes are steep Catskill till with shallow sandstone and are within the New York City watershed.

Delaware County is the highest and steepest terrain in the Southern Tier portion of this region, sitting on the western Catskill front with summits above 3,000 feet and deep valleys along the East and West branches of the Delaware River. The dominant series are unlike those to the west. Vly, Willowemoc, Lewbeach, Halcott, Onteora and Mongaup are formed in reddish till derived from Catskill sandstone, siltstone and shale, and most of them carry a fragipan or dense substratum. Willowemoc and Lewbeach are moderately deep to deep with a fragipan generally 18 to 26 inches down. Halcott is shallow, commonly less than 20 inches over bedrock. Lackawanna, Wellsboro, Bath and Mardin appear on the lower slopes and also carry fragipans. Valley bottoms hold narrow outwash and alluvial terraces. Design frost depth is roughly 48 inches and snow loading is heavier than anywhere else in the Southern Tier.
Delaware County is the most expensive civil ground in the Southern Tier and should be priced that way. Slopes are long and steep, so pad construction means benching, retained cut, and a genuine cut and fill balance study rather than a nominal one. Halcott and the shallower Catskill series put sandstone and siltstone inside foundation and trench depth, and Catskill bedrock is harder than the shale to the west, so hammer and blasting provisions are more likely than rippable rock. The fragipan under Willowemoc, Lewbeach, Lackawanna and Wellsboro perches water, so enclosure pads need interception drainage and an underdrained section. New York City watershed stormwater review drives tight sediment and erosion control, phased disturbance limits and early permanent stabilization. Access roads need sustained grade design, armored ditching and heavier subbase. The working season is the shortest in the Southern Tier.

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 no Delaware County municipality appears on the statewide battery energy storage moratorium tracking with an active utility scale moratorium. New York City watershed regulations administered through the Department of Environmental Protection apply across much of the county and add a separate stormwater and disturbance review on top of town site plan approval.
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.
