Site Diligence Analysis: Peoria County, IL (APN: 0423101001)

As a senior BESS site evaluation analyst for Sunland America Corp, I have performed a comprehensive diligence analysis for the property located in Peoria County, Illinois, identified by APN 0423101001. This analysis focuses on its suitability for distribution-scale (≤5MW) and utility-scale BESS projects, considering all provided data points and flagging critical unknowns.

1. Site Access & Topography

• Road Access Quality and Equipment Delivery Feasibility: The "Road Access" field is currently empty, which is a significant data gap. Given the "Agricultural/Rural" zoning and unincorporated county jurisdiction, it is highly probable that access is via a rural, unpaved, or minimally paved road. Such roads typically require significant upgrades (widening, paving, reinforcement) to accommodate heavy equipment like transformer skids, battery containers, and construction vehicles. This will add substantial cost and time to the project.
• Likely Terrain Characteristics: With "Agricultural/Rural" zoning and a total acreage of 7.6 acres, the terrain is likely to be relatively flat and open, potentially having been previously farmed. This is generally favorable for BESS construction, minimizing extensive grading and earthwork.
• Heavy Equipment Access: While the flat terrain is beneficial, the unknown quality of road access is the primary constraint. Assuming a typical rural road, heavy equipment access will be feasible only after significant road improvements are made. This includes ensuring adequate turning radii at intersections and on-site, as well as load-bearing capacity for oversized/overweight transport.
• Access Easement Concerns: The "POI Access" field is empty, indicating an unknown regarding specific access points or existing easements. It is critical to verify if the property has direct frontage on a public road or if an access easement across neighboring parcels is required. If an easement is needed, securing it can be a lengthy and complex process, potentially involving negotiations with adjacent landowners.

2. Environmental Constraints

• FEMA Flood Zone Designation and Implications: The FEMA Flood Zone designation is "Unknown." This is a critical environmental risk. BESS installations must be sited outside of 100-year floodplains (Zone AE/A) or engineered to withstand flood events, which can significantly increase foundation and structural costs. Immediate verification of the flood zone is required through a detailed flood plain map analysis.
• Wetlands Presence and Setback Requirements: The presence of wetlands is "Unknown." This is another major environmental risk. Wetlands typically require significant setbacks (e.g., 50-100 feet or more, depending on classification) and can trigger complex and lengthy permitting processes (e.g., US Army Corps of Engineers Section 404 permits) if avoidance is not possible. A comprehensive wetland delineation study is an urgent next step.
• Critical Habitat / Endangered Species Risk: The data indicates "None" for critical habitat. This is a positive finding, reducing the risk of project delays or costly mitigation measures related to endangered species protection.
• Brownfield/Superfund Status: The data states "None within ~2 miles." This indicates no immediate environmental contamination risk from nearby sites, which is favorable. However, it also means the project will not qualify for the IRA Brownfield ITC bonus adder, which could have provided a significant financial uplift.
• Chesapeake Bay Critical Area Implications: The data correctly notes "N/A (non-MD)," confirming no applicability for this site in Illinois.
• Pipeline Proximity Safety Considerations: The data indicates "None within ~3 miles." This is a positive safety finding, as proximity to high-pressure gas or hazardous liquid pipelines can impose significant setback requirements, safety studies, and operational restrictions, increasing project complexity and cost.

3. Grid Infrastructure & Interconnection

• Nearest Substation: The distance and maximum voltage of the nearest substation are "Unknown." This is a critical data gap for evaluating distribution-scale interconnection. Without this information, assessing available capacity and the feasibility of a distribution-level connection is impossible.
• Nearest Transmission Line: A 138kV transmission line owned by AMEREN ILLINOIS COMPANY is located at 1.0 mile. This is a significant asset for potential utility-scale interconnection.
• Likely Interconnection Voltage: Given the 138kV transmission line at 1.0 mile, a transmission-level interconnection is a strong possibility, especially for projects exceeding 5MW. For distribution-scale (≤5MW), the preference would typically be to interconnect at a lower voltage (e.g., 12.47kV, 34.5kV) if a suitable distribution substation with available capacity is nearby. However, without substation data, the optimal voltage remains uncertain. We will initially explore both distribution (if a substation is viable) and transmission options.
• Estimated Interconnection Cost Range and Timeline:
  • Distribution Interconnection (if viable): Costs could range from $500,000 to $2,000,000+, depending on substation upgrades, feeder length, and protection requirements. Timelines typically range from 18-36 months.
  • Transmission Interconnection (138kV): Costs are significantly higher, potentially ranging from $3,000,000 to $10,000,000+ for a new switchyard or line extension, depending on the point of interconnection (POI) and required network upgrades. Timelines typically range from 36-60+ months.
  These are broad estimates; actual costs and timelines are highly dependent on the specific POI and Ameren's system impact studies.
• Utility-Specific IX Process and Typical Queue Times: The interconnecting utility is Ameren Illinois Company. Ameren operates under MISO (Midcontinent Independent System Operator) for transmission-level interconnections and has its own state-regulated process for distribution interconnections. Both processes are known to be lengthy, with queue times for studies and approvals often extending for several years, particularly for transmission-level projects.
• Likely Feeder Configuration: "Unknown." This cannot be determined without knowing the nearest substation and its associated feeders. This information is crucial for distribution-level interconnection studies.

4. Regulatory & Zoning Analysis

• Authority Having Jurisdiction (AHJ) and its Type: The AHJ is Unincorporated Peoria County, Illinois. This means the county government is the primary permitting authority.
• Current Zoning for BESS Compatibility: The property is zoned "Agricultural/Rural - Agricultural / Rural (General) (Code: -)" and "A2" (Regrid). Agricultural zoning is generally not compatible with BESS as a "by-right" use. BESS facilities are typically considered industrial or utility uses.
• Recommended Permitting Pathway: Given the A2 zoning, a "by-right" permitting pathway is highly unlikely. The most probable pathway will be a Conditional Use Permit (CUP) or Special Use Permit (SUP) from Peoria County. This process involves public hearings, discretionary review by the planning commission and county board, and adherence to specific conditions. A variance is a last resort and generally harder to obtain.
• Known Setback Requirements for BESS: Specific setback requirements for BESS in Peoria County are "Unknown." This requires immediate research into the Peoria County Zoning Ordinance. Typical setbacks for utility structures in rural/agricultural zones can range from 50-200 feet from property lines, residential structures, and public roads.
• Reference Specific State/County Regulations: Illinois has state-level regulations for large-scale renewable energy projects (e.g., Public Act 102-1123 for solar and wind), which may influence county-level ordinances for BESS. However, specific BESS regulations at the county level for Peoria County need to be thoroughly investigated.
• Moratorium or Restriction Risks: "Unknown." Rural counties in Illinois have, in some instances, implemented moratoria or restrictive ordinances on new energy projects (especially solar and wind) due to local opposition or a desire to update zoning codes. This risk needs to be investigated through engagement with county planning staff and review of recent county board minutes.

5. IRA/ITC Incentive Analysis

• Opportunity Zone Eligibility: The property is designated "No" for Opportunity Zone eligibility. This means the project will not qualify for the additional 10% ITC adder.
• Energy Community Status: The property is designated "No" for Energy Community status. This means the project will not qualify for the additional 10% ITC adder.
• Low-Income Community Qualification: The property is designated "No" for Low-Income Community qualification. This means the project will not qualify for the additional 10% or 20% ITC adder.
• Calculate Potential Cumulative ITC Adder Percentage: Based on the current data, the potential cumulative ITC adder percentage for this site is 0%. This is a significant drawback, as these adders can substantially improve project economics and competitiveness.

6. BESS Score & Rationale

Overall BESS Suitability Score: 45/100

• Location (0-20): 12
  • Rationale: 7.6 acres is a decent size for a distribution-scale project, and the likely flat agricultural terrain is buildable. However, the unknown road access quality and potential easement needs introduce significant uncertainty and cost.
• Grid Access (0-25): 10
  • Rationale: The presence of a 138kV transmission line at 1.0 mile is a strong positive for utility-scale. However, the complete lack of information on the nearest substation (distance, voltage, capacity) severely handicaps the evaluation for distribution-scale, which is a primary focus. This major data gap significantly reduces the score.
• Environmental (0-15): 3
  • Rationale: "Unknown" for FEMA Flood Zone and Wetlands are critical red flags. These represent potentially project-killing constraints or extremely high mitigation costs. While other environmental factors are clear (no critical habitat, no pipelines, no brownfield risk), these two unknowns dominate the environmental risk profile.
• Regulatory (0-15): 5
  • Rationale: Agricultural (
