Site Diligence Analysis for Sunland America Corp.

This comprehensive site diligence analysis evaluates the property located in Macon County, IL (APN: 07-07-26-200-005) for its suitability as a Battery Energy Storage System (BESS) site. The analysis considers distribution-scale (≤5MW) and potential utility-scale applications, focusing on critical factors for successful development.

1. Site Access & Topography

• Road Access Quality and Equipment Delivery Feasibility: The property benefits from "Public" road access, which is a significant advantage for BESS development. Public roads typically imply a certain standard of maintenance and width, facilitating the transport of heavy equipment. The "POI requires extension in public ROW" indicates that while the point of interconnection (POI) is not directly adjacent to the site, the necessary infrastructure extension will occur within a public right-of-way, simplifying permitting compared to private land easements. This suggests good feasibility for delivering oversized loads such as transformers, battery containers, and other heavy construction machinery.
• Likely Terrain Characteristics: The property's "Agricultural/Rural - Farm (Irrigated Or Dry)" land use and "Buildability: Great" designation strongly suggest a relatively flat and open terrain. This is ideal for BESS installations, minimizing earthwork, grading, and foundation costs. The absence of significant topographical challenges will contribute to a more efficient and cost-effective construction process.
• Heavy Equipment Access: Given the public road access and "Great" buildability, heavy equipment access to the site is highly feasible. The flat, agricultural nature of the land should allow for easy maneuverability and staging of construction vehicles and components.
• Access Easement Concerns: No specific access easement concerns are noted for the site itself, as it fronts a public road. The mention of "POI requires extension in public ROW" implies potential utility easements for the interconnection line, but these are typically standard for BESS projects and less problematic than private land access easements.

2. Environmental Constraints

• FEMA Flood Zone Designation: The FEMA Flood Zone is currently Unknown. This is a critical data gap. A BESS facility must be sited outside of 100-year floodplains (Zone AE or A) or engineered to withstand flood events, which significantly increases costs and complexity.
  • Implication: Requires immediate verification. Siting within a flood zone could be a project killer or necessitate expensive flood mitigation measures (e.g., elevated platforms, floodwalls).
• Wetlands Presence and Setback Requirements: Wetlands presence is also Unknown. Wetlands trigger federal (USACE Section 404) and state permitting, requiring avoidance or mitigation. Setbacks from wetlands are common.
  • Implication: Requires a professional wetlands delineation. Presence of wetlands could reduce developable area or lead to costly permitting delays and mitigation.
• Critical Habitat / Endangered Species Risk: The data indicates "None" for Critical Habitat. This is a positive finding, as it reduces the risk of lengthy environmental reviews and potential project delays associated with the Endangered Species Act.
• Brownfield/Superfund Status: "1 site(s) within ~2 mi" is noted. This means the project site itself is not a brownfield. While not directly on-site, proximity to a brownfield could raise concerns about potential off-site contamination migration or require additional environmental due diligence (e.g., soil and groundwater testing) to ensure the BESS site is not impacted. It does not qualify for the IRA brownfield bonus.
  • Implication: Not an IRA advantage. Requires a Phase I Environmental Site Assessment (ESA) to assess potential off-site impacts.
• Chesapeake Bay Critical Area Implications: The data confirms "N/A (non-MD)," so this constraint is not applicable to the Illinois site.
• Pipeline Proximity Safety Considerations: "None within ~3 miles" is a significant positive. Proximity to high-pressure gas or hazardous liquid pipelines introduces substantial safety setbacks, risk assessments, and potential permitting hurdles. The absence of nearby pipelines simplifies site layout and reduces safety-related development costs and risks.

3. Grid Infrastructure & Interconnection

• Nearest Substation: The "Decatur Mound Road" substation is exceptionally close at 3,000 ft (approximately 0.57 miles). Its maximum voltage is 69 kV. This proximity is a major advantage, minimizing line extension costs and potential losses.
• Nearest Transmission Line: A 138kV transmission line owned by AMEREN ILLINOIS COMPANY is located at 0.5 miles. This provides excellent optionality for future expansion or higher voltage interconnection if needed.
• Recommended Interconnection Voltage: The specified "IX Voltage: 12.9 kV" indicates a distribution-level interconnection. For a distribution-scale project (≤5MW), this is appropriate and generally less complex and costly than a transmission-level interconnection. Given the 69kV substation is so close, it's likely the 12.9kV feeder originates from this substation.
• Estimated Interconnection Cost Range and Timeline:
  • Cost: For a 12.9 kV distribution interconnection requiring a 3,000 ft extension in public ROW, costs could range from $500,000 to $1,500,000+, depending on required feeder upgrades, substation modifications, and utility-specific charges. This estimate includes line extension, protection, and metering.
  • Timeline: Ameren Illinois' interconnection process typically involves a multi-stage queue. A distribution-level study could take 12-24 months from initial application to a signed Interconnection Agreement, not including construction time.
• Utility-Specific IX Process and Typical Queue Times: The interconnecting utility is Ameren Illinois Company. Ameren's interconnection process is well-established, involving application, system impact study, facilities study, and an interconnection agreement. Queue times can be substantial, especially for larger projects or those requiring significant system upgrades. For a distribution-scale project, it's crucial to understand the specific feeder capacity at 12.9 kV from the Decatur Mound Road substation.
• Likely Feeder Configuration: The 12.9 kV interconnection voltage strongly suggests a radial feeder configuration originating from the Decatur Mound Road substation. Further investigation is needed to determine if it's a dedicated feeder or a shared feeder with existing loads, which impacts available capacity.

4. Regulatory & Zoning Analysis

• Authority Having Jurisdiction (AHJ) and Type: The AHJ is Unincorporated (county jurisdiction), specifically Macon County, IL. This is generally favorable as county-level permitting can sometimes be less restrictive or complex than municipal processes, particularly for industrial-type uses in rural areas.
• Current Zoning for BESS Compatibility: The current zoning is "Agricultural/Rural - Farm (Irrigated Or Dry) (Code: A-1)". BESS facilities are typically not a "by-right" use in agricultural zones. This will require a discretionary review process.
• Recommended Permitting Pathway: The most likely permitting pathway will be a Conditional Use Permit (CUP) or a Special Use Permit (SUP) from Macon County. This process involves public hearings, demonstrating compatibility with the surrounding area, and adherence to specific conditions. A variance is less likely unless specific setback requirements cannot be met.
• Known Setback Requirements: Specific setback requirements for BESS in Macon County's A-1 zone are Unknown and require immediate verification. Typical setbacks can range from 50-200 feet from property lines, residential structures, and public roads.
• Reference Specific State/County Regulations: Illinois does not have a statewide BESS siting law for projects under 10 MW, meaning local zoning ordinances (Macon County) will govern. However, the Illinois Commerce Commission (ICC) regulates utility interconnection. Macon County's Unified Development Ordinance (or equivalent) will contain the specific requirements for CUP/SUP applications and setbacks.
• Moratorium or Restriction Risks: Any known moratoriums or restrictions on BESS development in Macon County are Unknown. This needs to be investigated, as some rural counties have implemented temporary bans or strict regulations due to public perception or lack of specific ordinances.

5. IRA/ITC Incentive Analysis

• Opportunity Zone Eligibility: The property is Not located in an Opportunity Zone. Therefore, no additional ITC bonus is available from this incentive.
• Energy Community Status: The property is located in an Energy Community due to "Fossil Fuel Employment (FFE Area)". This qualifies the project for a 10% ITC adder. This is a significant positive for project economics.
• Low-Income Community Qualification: The property is Not located in a Low-Income Community. Therefore, no additional ITC bonus is available from this incentive.
• Calculate Potential Cumulative ITC Adder Percentage: Based on the current data, the cumulative ITC adder percentage for this project is 10%, derived solely from its Energy Community status. This means a project eligible for the base 30% ITC would receive a 40% ITC.

6. BESS Score & Rationale

BESS Suitability Score: 72/100

• Location (17/20): Excellent buildability ("Great") and public road access are strong positives. The agricultural setting is generally favorable for large-scale development.
• Grid Access (23/25): Outstanding proximity to both a 69kV substation (3,000 ft) and a 138kV transmission line (0.5 mi). The 12.9kV IX voltage is appropriate for distribution-scale. The only minor deduction is the need for a 3,000 ft line extension, which adds cost.
• Environmental (8/15): Significant deductions due to Unknown FEMA Flood Zone and Wetlands status. Proximity to a brownfield site (even if off-site) is a minor concern. The absence of critical habitat and pipelines is a strong positive.
• Regulatory (10/15): The A-1 zoning requiring a CUP/SUP is a hurdle, increasing permitting time and risk. However, being in an unincorporated county jurisdiction can be less onerous than a dense municipality. Unknown setbacks and moratorium risks are concerns.
• Incentives (7/15): Only a 10% ITC adder from Energy Community status. No Opportunity Zone or Low-Income Community benefits.
• Buildability (7/10): "Great" buildability is a strong positive, suggesting minimal site preparation costs. Minor deduction for potential unknown subsurface conditions (e.g., rock, soil contamination from nearby brownfield).

7. Key Risks & Mitigants

• Risk 1: Zoning & Permitting Complexity (A-1 Zone): The A-1 zoning requires a Conditional Use Permit (CUP) or Special Use Permit (SUP), which is a discretionary process involving public hearings and potential opposition.
  • Mitigant: Engage early with Macon County Planning & Zoning. Develop a robust community engagement plan. Prepare a comprehensive application demonstrating minimal impact, safety measures, and economic benefits. Secure a land option agreement before significant permitting spend.
• Risk 2: Environmental Unknowns (Flood Zone & Wetlands): The unknown status of FEMA flood zone and wetlands could significantly impact developable area, project costs, or even viability.
  • Mitigant: Immediately commission a Phase I Environmental Site Assessment (ESA), a wetlands delineation, and precise FEMA flood zone mapping for the parcel. These are critical go/no-go items.
