⚡ 7007 MARIAH FURNACE RD

As a senior BESS site evaluation analyst for Sunland America Corp, I have performed a comprehensive diligence analysis for the property located at 7007 MARIAH FURNACE RD, Washington County, MD. This analysis focuses on distribution-scale (≤5MW) and utility-scale BESS projects, evaluating the site's suitability across critical development vectors.

1. Site Access & Topography

• Road Access Quality: The property benefits from "Public" road access, which is a significant advantage for equipment delivery and ongoing operations. This suggests that standard heavy haul routes are likely available to reach the site perimeter.
• Equipment Delivery Feasibility: Given public road access and the "Buildability: OK" assessment, the delivery of heavy equipment such such as transformers, switchgear, and battery containers (typically 20-40 ft ISO containers) should be feasible. However, the internal site access from the public road to the actual Point of Interconnection (POI) or BESS pad will require further investigation.
• Terrain Characteristics: With 91.52 acres zoned "Residential - Rural/Agricultural Residence (EC)", the site is likely characterized by rural, potentially undulating terrain typical of agricultural or undeveloped land in Washington County. The "Buildability: OK" note suggests that significant grading or earthwork challenges are not anticipated, but a detailed geotechnical survey will be essential. The large acreage provides flexibility for optimal BESS layout and necessary setbacks.
• Heavy Equipment Access: Assuming the public road is suitable for heavy vehicle loads, the primary concern for heavy equipment access is the internal route from the public road to the BESS pad. This will require a detailed site survey to identify suitable internal access roads and potential need for road improvements or temporary access routes.
• Access Easement Concerns: A critical flag is "POI requires private easements." This indicates that while the property itself has public road access, the path from the property boundary to the actual Point of Interconnection with the grid infrastructure (substation or transmission line) crosses land not owned by the project. Negotiating these private easements will be a key project risk and can impact both timeline and cost.

2. Environmental Constraints

• FEMA Flood Zone Designation: The FEMA Flood Zone is "Unknown." This is a critical data gap. BESS facilities must be sited outside of 100-year floodplains (Zone AE or A) or require significant, costly flood mitigation measures. Immediate verification is required.
• Wetlands Presence and Setback Requirements: Wetlands presence is also "Unknown." Maryland has stringent wetland protection regulations, and the presence of state or federally regulated wetlands could significantly constrain the buildable area, trigger lengthy permitting processes (e.g., Section 404/401 permits), and necessitate costly mitigation. A Phase I Environmental Site Assessment (ESA) and wetland delineation are essential.
• Critical Habitat / Endangered Species Risk: The data indicates "Critical Habitat: None" and "Protected Areas: None." This is a positive finding, reducing the risk of delays or project redesigns due to endangered species act compliance.
• Brownfield/Superfund Status: "None within ~2 miles." This means the site does not qualify for the IRA brownfield bonus adder, but also avoids the environmental remediation risks and liabilities associated with such sites.
• Chesapeake Bay Critical Area Implications: The property is "No" within the Chesapeake Bay Critical Area. This is a significant advantage, as it avoids the highly restrictive development regulations and increased permitting complexity associated with projects within this sensitive watershed.
• Pipeline Proximity Safety Considerations: "None within ~3 miles." This eliminates concerns regarding pipeline safety setbacks, potential blast zones, and the need for additional safety studies or coordination with pipeline operators, which can be complex and costly.
• Gas Wells Nearby: "None within ~2 miles." This is also positive, avoiding potential safety, environmental, or operational conflicts with active or abandoned gas infrastructure.

3. Grid Infrastructure & Interconnection

• Nearest Substation: The nearest substation, "UNKNOWN122882," is an exceptional 0.3 miles away with a "Max Voltage: 230 kV." This extremely close proximity to high-voltage infrastructure is a major advantage, significantly reducing interconnection line costs and potential right-of-way acquisition challenges.
• Nearest Transmission Line: A 230kV transmission line owned by "THE POTOMAC EDISON COMPANY" is located at an outstanding 0.1 miles. This direct access to a major transmission asset is ideal for utility-scale BESS projects.
• Interconnecting Utility: Based on the transmission line owner, the interconnecting utility is almost certainly Potomac Edison (a FirstEnergy company). The provided UUID "39a55b46-fd6d-4ef4-abe2-7e18a192b596" is likely an internal identifier.
• Recommended Interconnection Voltage: Given the immediate proximity to 230kV substation and transmission lines, a transmission-level interconnection at 230kV is highly recommended. While the project is distribution-scale (≤5MW), connecting at transmission voltage can offer greater grid stability, potentially higher available capacity, and avoid distribution feeder constraints.
• Estimated Interconnection Cost Range and Timeline: The extremely short distance to the 230kV infrastructure should minimize the cost of the generation tie-line. However, 230kV interconnections are inherently complex, requiring significant substation upgrades (breaker, relaying, protection schemes) and potentially new bay additions.
  • Cost: Expect a range of $2,000,000 - $5,000,000+ for a 230kV interconnection, heavily dependent on required substation upgrades and the utility's specific requirements. The short tie-line will save significant costs here.
  • Timeline: A 230kV interconnection in the PJM territory (which includes Maryland) typically follows a multi-stage process (Feasibility, System Impact, Facilities Studies) that can take 24-48 months from initial application to Commercial Operation Date (COD), assuming no major system upgrades are identified.
• Utility-Specific IX Process and Typical Queue Times: Potomac Edison operates within the PJM Interconnection RTO. PJM's interconnection queue is known for its length and complexity, though recent reforms aim to streamline it. Typical queue times for a project of this size can be substantial, as noted above. Early engagement with Potomac Edison and PJM is crucial.
• Likely Feeder Configuration: Not applicable for a recommended transmission-level interconnection. If a distribution connection were pursued (e.g., 34.5kV or 12.47kV), the feeder configuration would need to be identified, but this is less optimal given the available 230kV infrastructure.

4. Regulatory & Zoning Analysis

• Authority Having Jurisdiction (AHJ) and Type: The AHJ is "Unincorporated (county jurisdiction)," meaning Washington County, MD, is the primary permitting authority.
• Current Zoning for BESS Compatibility: The current zoning is "Residential - Rural/Agricultural Residence (Code: EC)." This is a significant red flag. BESS facilities, even distribution-scale, are typically classified as industrial or utility uses. It is highly unlikely that a BESS would be permitted "by-right" in a residential or agricultural zone. This will be the primary regulatory hurdle.
• Recommended Permitting Pathway: Given the zoning, the most probable permitting pathway will be a Conditional Use Permit (CUP) or Special Exception. This process involves public hearings, detailed site plans, and demonstrating that the project meets specific conditions and does not negatively impact the surrounding community. A variance is a less desirable and more difficult pathway, typically reserved for minor deviations.
• Known Setback Requirements: Washington County's zoning ordinance will need to be thoroughly reviewed for specific setback requirements for utility-scale facilities or industrial uses in rural/residential zones. Typical setbacks for BESS can range from 50-200 feet from property lines, residential structures, and public roads, depending on the jurisdiction and BESS size/technology. These will be critical for site layout.
• Specific State/County Regulations: Maryland has state-level regulations for power generation facilities, though BESS projects below a certain size (e.g., 70MW for Certificate of Public Convenience and Necessity) may fall under local jurisdiction. Washington County's zoning code (e.g., Chapter 195, Zoning) will govern the specific requirements for CUPs, setbacks, noise, visual impacts, and fire safety.
• Moratorium or Restriction Risks: While no specific BESS moratorium is noted, the "Residential - Rural/Agricultural Residence" zoning itself represents a significant restriction. There's a risk of strong local opposition from residents concerned about industrial development in their area, which can lead to project delays or even denial.

5. IRA/ITC Incentive Analysis

• Opportunity Zone Eligibility: The property is "No" in an Opportunity Zone. This means the project will not qualify for the additional 10% ITC adder associated with Opportunity Zones.
• Energy Community Status: The property is "No" in an Energy Community. This is a significant missed opportunity, as Energy Community status could provide an additional 10% ITC adder.
• Low-Income Community Qualification: The property is "No" in a Low-Income Community. This means it will not qualify for the 10% or 20% ITC adder available for projects in such communities.
• Calculated Potential Cumulative ITC Adder Percentage: Based on the provided data, the cumulative ITC adder percentage is 0%. The project would only qualify for the base 30% Investment Tax Credit (ITC) if prevailing wage and apprenticeship requirements are met. This significantly impacts project economics compared to sites that qualify for multiple adders.

6. BESS Score & Rationale

Overall BESS Suitability Score: 60/100

• Location (0-20): 14/20
  • Rationale: The large 91.52-acre parcel offers excellent flexibility for layout and setbacks. "Buildability: OK" is positive. However, the critical need for private easements for POI access introduces a significant risk and complexity, slightly reducing the score.
• Grid Access (0-25): 24/25
  • Rationale: Outstanding proximity to 230kV substation (0.3 mi) and transmission line (0.1 mi) is a major asset, minimizing tie-line costs. This is nearly ideal for grid interconnection. The only minor deduction is for the inherent complexity and timeline of 230kV interconnection.
• Environmental (0-15): 8/15
  • Rationale: Positive for no critical habitat, protected areas, brownfield/superfund, pipelines, or Chesapeake Bay Critical Area. However, the "Unknown" status for FEMA Flood Zone and Wetlands are major, unresolved risks that could significantly impact buildability and permitting. This uncertainty heavily weighs down the score.
• Regulatory (0-15): 5/15
  • Rationale: The "Residential - Rural/Agricultural Residence (EC)" zoning is a severe constraint. Permitting will almost certainly require a Conditional Use Permit, involving public hearings and potential local opposition, making it a high-risk and potentially lengthy process. This is the biggest regulatory hurdle.
