⚡ 40 MILLBURY RD

1. Site Access & Topography

The subject property at 40 Millbury Road is a 12.58-acre, undeveloped parcel in Oxford, MA. Initial desktop analysis indicates that primary access would be from Millbury Road, a two-lane local road. The quality of this road appears adequate for standard vehicles, but its suitability for heavy haul trucks required for BESS component delivery is a significant concern. A detailed route survey is necessary to assess turning radii, potential weight-limited bridges, and overhead line clearances between the nearest highway and the site.

Based on its location in Worcester County and its "Forest Land" use code, the site's topography is likely characterized by rolling hills, moderate to steep slopes, and dense tree cover. This presents several challenges for development. Significant tree clearing and earthwork, including grading and leveling, will almost certainly be required to create a suitable pad for the BESS containers, transformer, and switchgear. This will increase construction costs and may trigger additional environmental review under local or state regulations (e.g., tree removal bylaws).

The feasibility of delivering heavy equipment is questionable without significant site work. A new, robust access road would need to be constructed from Millbury Road onto the property, capable of supporting multi-ton loads from lowboy trailers carrying battery containers and the main power transformer. The current parcel does not appear to have an existing improved access point. Therefore, securing a curb cut permit from the Oxford Department of Public Works and potentially a permanent access easement across the frontage of the property will be a critical early step. The need for an easement is a key unknown and Requires Verification through a title search and survey.

2. Environmental Constraints

The environmental profile of this site presents several critical unknowns that constitute a high risk to the project schedule and budget.

• FEMA Flood Zone: The flood zone designation is currently Unknown. This is a critical data gap. Any designation other than Zone X (minimal risk) could render large portions of the site undevelopable or require costly mitigation, such as elevating all equipment above the Base Flood Elevation, which is often impractical for BESS. A formal flood zone determination is an immediate priority.
• Wetlands: The presence of wetlands is Unknown but highly probable on a forested parcel of this size in Massachusetts. The Massachusetts Wetlands Protection Act (WPA) and local Oxford conservation bylaws impose strict regulations, including significant buffer zones (typically 100 feet) around any delineated wetland resource areas. The presence of wetlands could severely constrain the buildable area and potentially make the site infeasible. A formal wetland delineation by a certified professional is essential.
• Critical Habitat / Species: The data indicates no critical habitat on site, which is a positive initial finding. However, this must be verified by cross-referencing the site location with the Massachusetts Natural Heritage & Endangered Species Program (NHESP) Priority Habitat maps to ensure no state-listed rare species or their habitats are present.
• Brownfield/Superfund Status: The absence of nearby brownfield or superfund sites is positive from a liability and cleanup-cost perspective. However, it also means the project is ineligible for the 10% IRA Brownfield Adder, which is a significant competitive disadvantage compared to projects sited on qualifying properties.
• Pipeline Proximity: The lack of major pipelines within three miles is a significant safety and design advantage, eliminating risks of explosion and costly setback or mitigation requirements.

3. Grid Infrastructure & Interconnection

The grid infrastructure presents the most significant challenge for a distribution-scale project at this location. The nearest substation, NORTH OXFORD, is 1.5 miles away and operates at a transmission voltage of 115 kV. Interconnecting a ≤5MW BESS at transmission level is economically non-viable due to the extreme cost of a 115 kV substation bay and associated protection equipment.

Therefore, the only feasible path is a distribution-level interconnection. The interconnecting utility is presumed to be National Grid, but this Requires Verification. We must identify a suitable three-phase distribution feeder running along Millbury Road or adjacent streets. The voltage, available capacity, and circuit configuration of this local feeder are all critical unknowns. A 1.5-mile line extension to the substation would be cost-prohibitive, likely exceeding $2 million and adding significant timeline risk. The project's viability is entirely dependent on the presence of a nearby distribution line with sufficient thermal and voltage headroom to accommodate a 5MW injection/withdrawal.

The interconnection process in Massachusetts is governed by the state DPU and managed by the utility (National Grid) under the ISO-New England tariff. Queue times are notoriously long, often 24-36 months from application to commercial operation. Given the distance to the substation and the residential nature of the area, significant and costly distribution system upgrades are highly likely. A formal Pre-Application Report from the utility is the only way to gain insight into feasibility and potential costs.

4. Regulatory & Zoning Analysis

The regulatory and zoning landscape for this parcel is exceptionally challenging and represents a potential fatal flaw. The Authority Having Jurisdiction (AHJ) is the Town of Oxford. The parcel is zoned R-1 (Residential) and designated as "Private Preserve, Open Space-Vacant Land."

A Battery Energy Storage System is an industrial utility use and is fundamentally incompatible with R-1 zoning. It is almost certain that BESS is not a permitted use "by-right." The permitting pathway would be arduous and uncertain, likely requiring one of the following:

• Special Permit: This is the most likely path if the town's zoning bylaw has provisions for public utility uses in residential zones, but it would require discretionary approval from the Planning Board after public hearings.
• Use Variance: This is extremely difficult to obtain in Massachusetts, as it requires proving a unique hardship related to the land itself, not just the owner's economic interest.

A review of Oxford's zoning bylaws is required to see if BESS is an explicitly defined use. If not, it would be considered an unlisted use, further complicating the process. Given the residential zoning, we anticipate intense local opposition from abutters concerned about noise, safety, and property values. The
