⚡ ASHBURNHAM HILL RD

1. Site Access & Topography

The subject property is located on Ashburnham Hill Road in Fitchburg, MA. Initial desktop analysis using satellite imagery indicates that Ashburnham Hill Road is a two-lane, paved public road that appears to be in fair to good condition. This level of access is generally sufficient for the delivery of construction materials and BESS equipment, including standard tractor-trailers. However, a detailed route survey is required to confirm the absence of low-clearance bridges, sharp turning radii, or weight-limited infrastructure between major highways and the site entrance.

The topography of Worcester County is characterized by rolling hills and forested terrain. This parcel appears to be heavily wooded with moderate elevation changes, which is typical for the region. Significant tree clearing and grading will almost certainly be required to create a level pad for the BESS compound, switchgear, and transformer. The cost and timeline for this site preparation work must be factored into the project's pro forma. A geotechnical survey will be essential to determine soil stability, the presence of bedrock, and suitability for foundation construction.

Access for heavy equipment, such as a 100-ton crane for setting transformers and battery containers, is a primary concern. While the public road seems adequate, access from the road onto the parcel itself does not exist. A new access road will need to be engineered and constructed. This will require a curb cut permit from the Fitchburg Department of Public Works and potentially an easement if the ideal access point crosses another property's frontage. The grade of this new access road must be carefully designed to accommodate low-slung transport vehicles. A critical data discrepancy exists regarding parcel size (19.66 acres vs. 2.4 acres). If the parcel is only 2.4 acres, achieving required setbacks and constructing a suitable access drive will be extremely challenging.

2. Environmental Constraints

Environmental factors present significant unknowns and potential risks for this site.

• FEMA Flood Zone: The flood zone designation is currently unknown. This is a critical data gap. Any designation within a 100-year floodplain (Zone A/AE) would likely render the site undevelopable for critical electrical infrastructure or require cost-prohibitive mitigation measures like elevating all equipment above the Base Flood Elevation. This must be verified immediately using the FEMA Flood Map Service Center.
• Wetlands: The presence of wetlands is unknown. Given the wooded and potentially low-lying areas of the parcel, there is a high probability of state or federally protected wetlands. Massachusetts has a stringent Wetlands Protection Act, which enforces significant buffer zones (typically 100 feet) from any delineated wetland resource area. A formal wetland delineation by a certified professional is a mandatory next step to determine the buildable area envelope.
• Critical Habitat / Species: The data indicates no critical habitat on site, which is a positive initial finding. However, we recommend cross-referencing the site with the US Fish & Wildlife Service's IPaC tool and the Massachusetts Natural Heritage & Endangered Species Program (NHESP) database to confirm no sensitive species or habitats are present that could trigger lengthy and complex consultations.
• Brownfield/Superfund Status: The presence of 41 potential contamination sites within a two-mile radius is a notable risk. It increases the likelihood of encountering on-site contamination from historical activities. A Phase I Environmental Site Assessment (ESA) is non-negotiable to assess this risk and establish a baseline. Conversely, if the site itself can be officially designated as a "brownfield" (e.g., due to historical dumping or other contamination), it could qualify for a valuable 10% ITC adder under the Inflation Reduction Act (IRA). This presents a dual-edged sword of potential liability versus financial incentive.
• Pipeline Proximity: The absence of major gas pipelines within three miles is a significant safety and design advantage, eliminating concerns related to pipeline setbacks and explosion risks.

3. Grid Infrastructure & Interconnection

The site's primary strength lies in its proximity to existing grid infrastructure. The River Street substation is located approximately 1.0 mile from the parcel. This is an excellent distance for a distribution-scale project, minimizing the cost and complexity of the generator lead line. The provided substation voltage of "-999999 kV" is a data error; substations in this area typically operate with distribution voltages such as 13.8kV. This must be verified with the interconnecting utility.

The interconnecting utility is presumed to be Unitil (operating locally as Fitchburg Gas and Electric Light Company), given they own the nearby transmission assets. The likely interconnection point would be a 3-phase overhead distribution feeder originating from the River Street substation. The key unknown is the available hosting capacity on the local circuits. A formal interconnection pre-application must be submitted to Unitil to obtain a screening report on thermal capacity, voltage constraints, and protection system limitations.

Given the project scale (≤5MW), a distribution-level interconnection (e.g., 13.8kV) is the only economically viable option. The nearby 115kV
