Site Diligence Analysis for Kane County, IL BESS Project

Sunland America Corp. has evaluated the provided property data for a potential Battery Energy Storage System (BESS) project in Kane County, Illinois. This comprehensive analysis assesses the site's suitability across various critical dimensions, identifying key opportunities, risks, and recommended next steps.

1. Site Access & Topography

• Road Access Quality and Equipment Delivery Feasibility: The property is explicitly noted as "Landlocked," which presents a significant and immediate challenge. This means there is no direct public road frontage, and access to the site would require traversing adjacent private parcels. The data further states, "POI requires private easements," confirming that securing legal and physical access is a prerequisite for any development. This is a critical hurdle for equipment delivery.
• Likely Terrain Characteristics: The zoning is "Agricultural/Rural," which typically suggests relatively flat to gently rolling terrain, conducive to BESS development. The "Buildability: OK" and "Buildable Acres: 8.7" further support that a portion of the site is physically suitable for construction, assuming access is resolved. However, the lack of specific topographical data means this is an assumption based on typical agricultural land use in the region.
• Heavy Equipment Access: Without established access easements, heavy equipment such as transformers, battery containers, and construction machinery cannot reach the site. Even with easements, the quality and width of the easement road would need to be sufficient to support oversized and overweight vehicle loads. This will require significant upfront investment in road construction or upgrades within the easement corridor.
• Access Easement Concerns: The primary concern is the negotiation and acquisition of perpetual access easements from neighboring landowners. This process can be time-consuming, costly, and may face resistance. Key considerations include the number of parcels to cross, the willingness of landowners, and the legal costs associated with drafting and recording robust easement agreements that permit heavy industrial use. This is a fundamental go/no-go decision point.

2. Environmental Constraints

• FEMA Flood Zone Designation: The FEMA Flood Zone is listed as "Unknown." This is a critical data gap. Illinois, particularly near rivers and tributaries, can have significant floodplains. A BESS located in a 100-year floodplain (AE or VE zones) would face substantial permitting challenges, require elevated equipment, and incur increased engineering and insurance costs. This requires immediate verification through a flood plain analysis.
• Wetlands Presence and Setback Requirements: Wetlands are also listed as "Unknown." Given the "Agricultural/Rural" zoning, there is a possibility of isolated wetlands or drainage features. Wetland delineation would be necessary to identify any jurisdictional wetlands. If present, federal (USACE) and state (IEPA) permits would be required, and BESS components would need to adhere to significant setback requirements, potentially reducing the usable buildable area.
• 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 modifications due to ecological concerns.
• Brownfield/Superfund Status: The site is noted as "None within ~2 miles." This means there are no immediate environmental contamination risks from nearby sites, which is favorable. However, it also means the project would not qualify for the IRA Brownfield ITC bonus adder, as the site itself is not designated as a brownfield.
• Chesapeake Bay Critical Area Implications: The data correctly states "N/A (non-MD)," indicating this is not a concern for a project in Illinois.
• Pipeline Proximity Safety Considerations: The data confirms "None within ~3 miles." This is a significant positive, as proximity to high-pressure gas or hazardous liquid pipelines can introduce substantial safety setbacks, risk assessments, and additional permitting complexities, often requiring extensive engagement with pipeline operators.

3. Grid Infrastructure & Interconnection

• Nearest Substation: The Rutland Substation is 1.5 miles away with a Max Voltage: 138 kV. This is an excellent proximity for a BESS project, suggesting relatively short interconnection lines.
• Nearest Transmission Line: A 138kV transmission line (COMMONWEALTH EDISON CO) is also 1.5 miles away, aligning with the substation location. This provides robust grid access.
• Likely Interconnection Voltage: The specified IX Voltage is 34.5 kV. This indicates a distribution-level interconnection, which is typical for projects up to 5MW. While the substation and transmission line are 138kV, the project would likely tap into a 34.5kV feeder originating from that substation. This is generally less complex and costly than a direct transmission-level interconnection for a distribution-scale project.
• Estimated Interconnection Cost Range and Timeline: For a 1.5-mile distribution-level interconnection, costs could range from $500,000 to $1,500,000+, depending on required line upgrades, substation modifications, and protection schemes. The timeline for interconnection with Commonwealth Edison (ComEd) is notoriously long. Expect 24-48 months from application submission to energization, including study phases (Feasibility, System Impact, Facilities) and construction.
• Utility-Specific IX Process and Typical Queue Times: ComEd operates under MISO (Midcontinent Independent System Operator) rules for larger projects, but distribution-level interconnections follow ComEd's specific tariffs and processes. ComEd's interconnection queue is often congested, leading to extended study timelines. Early engagement and a robust application are crucial.
• Likely Feeder Configuration: The specific feeder configuration is "Unknown." This is a critical piece of information. We need to understand if the 34.5kV feeder has sufficient capacity, is radial or networked, and what its existing loading and reliability issues might be. This will be determined during the interconnection study process.

4. Regulatory & Zoning Analysis

• Authority Having Jurisdiction (AHJ): The AHJ is "Unincorporated (county jurisdiction)," specifically Kane County, IL. This is generally preferable to a dense municipal jurisdiction, as county planning departments often have more experience with larger-scale land uses and potentially more flexible zoning ordinances.
• Current Zoning for BESS Compatibility: The current zoning is "Agricultural/Rural - Agricultural / Rural (General) (Code: F)." BESS facilities are typically not "by-right" uses in agricultural zones. This zoning will likely require a discretionary approval.
• Recommended Permitting Pathway: The most probable permitting pathway will be a Conditional Use Permit (CUP) or Special Use Permit (SUP) from Kane County. This process involves public hearings, detailed site plans, and addressing specific conditions related to noise, visual impacts, setbacks, and safety. A variance is less desirable as it implies a deviation from the zoning code rather than a permitted use under specific conditions.
• Known Setback Requirements: Specific setback requirements for BESS in Kane County are "Unknown." These will need to be thoroughly researched. Typical setbacks for BESS can range from 50-200 feet from property lines and residential structures, impacting the usable buildable area.
• State/County Regulations: Illinois has state-level regulations for energy facilities, but local zoning is paramount for distribution-scale projects. Kane County's Unified Development Ordinance (UDO) will govern the CUP/SUP process. Illinois also has specific fire code requirements for BESS (e.g., NFPA 855 adoption).
• Moratorium or Restriction Risks: There are no known moratoriums or restrictions specifically noted. However, local opposition to BESS projects is growing in some rural areas. A pre-application meeting with Kane County planning staff is essential to gauge their receptiveness and identify any potential local sentiment issues.

5. IRA/ITC Incentive Analysis

• Opportunity Zone Eligibility: The property is designated as "No" for Opportunity Zone eligibility. This means the project will not qualify for the additional 10% ITC adder associated with Opportunity Zones.
• Energy Community Status: The property is designated as "Yes — Fossil Fuel Employment (FFE Area)." This is a significant positive, qualifying the project for a 10% ITC adder under the Energy Community provisions. This is based on the Department of Treasury's guidance for areas with significant fossil fuel employment or tax revenues.
• Low-Income Community Qualification: The property is designated as "No" for Low-Income Community qualification. This means the project will not qualify for the additional 10% or 20% ITC adder available for projects in low-income communities or on tribal land.
• Calculate Potential Cumulative ITC Adder Percentage: Based on the current information, the project qualifies for a 10% cumulative ITC adder due to its location within an Energy Community (FFE Area). This is in addition to the base 30% ITC, bringing the total potential ITC to 40%.

6. BESS Score & Rationale

BESS Suitability Score: 55/100

• Location (0-20): 5/20
  • Rationale: The "Landlocked" status is a severe impediment, requiring significant effort and cost to secure access. While the overall agricultural setting might be suitable, the lack of direct road access severely devalues the location.
• Grid Access (0-25): 20/25
  • Rationale: Excellent proximity (1.5 miles) to a 138kV substation and transmission line is a major advantage. The 34.5kV IX voltage is appropriate for distribution-scale. The primary detractor is the unknown feeder configuration and ComEd's long interconnection queue, but the physical proximity is strong.
• Environmental (0-15): 8/15
  • Rationale: Positive for no critical habitat, brownfield, or pipeline proximity. However, the "Unknown" status for FEMA flood zones and wetlands introduces significant unquantified risks and potential costs, preventing a higher score.
• Regulatory (0-15): 7/15
  • Rationale: Unincorporated county AHJ is generally favorable. However, "Agricultural/Rural" zoning is not by-right for BESS, necessitating a more complex and potentially contentious CUP/SUP process. Unknown setback requirements and potential local opposition are concerns.
• Incentives (0-15): 10/15
  • Rationale: Qualification as an Energy Community (FFE Area) for a 10% ITC adder is a strong positive. The lack of Opportunity Zone or Low-Income Community status prevents a perfect score but the 10% adder is valuable.
• Buildability (0-10): 5/10
  • Rationale: "Buildability: OK" for 8.7 acres is good, suggesting a suitable physical footprint. However, the "Landlocked" status directly impacts buildability by making equipment delivery impossible without significant upfront work on access, hence the lower score.

7. Key Risks & Mitigants

• Risk 1: Landlocked Property & Access Easement Acquisition.
  • Mitigant: Initiate immediate outreach to adjacent landowners to gauge willingness to grant perpetual access easements. Conduct a detailed legal and survey review of potential access routes. Budget for significant legal fees, land acquisition costs, and potential road construction/upgrades within the easement. This is a primary go/no-go decision point.
• Risk 2: Zoning Incompatibility & Permitting Delays.
  • Mitigant: Schedule a pre-application meeting with Kane County Planning Department to discuss
