Site Diligence Analysis: Knox County, IL (APN: 920400008)

As a senior BESS site evaluation analyst for Sunland America Corp, I have performed a comprehensive diligence analysis for the property located in Knox County, IL (APN: 920400008). This analysis evaluates the site's suitability for a distribution-scale (≤5MW) or utility-scale BESS project, focusing on critical development factors and potential risks.

1. Site Access & Topography

The property benefits from Public Road Access, which is a significant advantage for logistics and construction. The data indicates "POI Onsite," meaning the Point of Interconnection is located directly on the property, which drastically reduces the need for off-site access easements for interconnection infrastructure and simplifies construction. The "Buildability: Great" assessment, coupled with 1.0 designated "Buildable Acres" out of 39.6 total acres, suggests that a specific, suitable area for the BESS footprint has been identified, likely implying favorable topography (flat or gently sloping) requiring minimal grading. This is crucial for efficient site development. Heavy equipment, including large transformers and battery containers, should have straightforward access to the buildable area given the public road access and onsite POI. While no specific access easement concerns are noted, a detailed survey will be required to confirm all necessary construction and operational easements are within the property boundaries or easily acquirable.

2. Environmental Constraints

Several critical environmental data points are currently Unknown, specifically the FEMA Flood Zone designation and the presence of Wetlands. These are high-priority items requiring immediate investigation, as both can significantly impact project design, permitting, and cost. A site within a 100-year floodplain (AE or VE zones) would necessitate elevated equipment and potentially extensive flood mitigation measures, increasing CAPEX and potentially delaying permitting. The presence of wetlands would trigger federal (USACE) and state permitting, requiring avoidance, minimization, or mitigation, which can be costly and time-consuming. Positively, there is No Critical Habitat and No Protected Areas identified, reducing ecological impact risks. Pipeline Proximity is also favorable, with none within approximately 3 miles, mitigating safety and setback concerns. The presence of "1 site(s) within ~2 mi" identified as a Brownfield/Superfund site needs clarification. If the *project site itself* is a brownfield, it could qualify for the IRA Brownfield ITC bonus adder. If it's an adjacent or nearby site, it poses a potential environmental contamination risk that would need to be assessed via a Phase I Environmental Site Assessment (ESA) to ensure no off-site migration impacts the project parcel. Chesapeake Bay Critical Area is correctly noted as N/A for Illinois.

3. Grid Infrastructure & Interconnection

The site boasts excellent grid infrastructure proximity. The Nearest Substation, Galesburg Monmouth Boulevard, is only 1 mile away with a maximum voltage of 138 kV. This close proximity is a significant advantage, minimizing interconnection line costs and potential right-of-way acquisition challenges. The stated IX Voltage is 69 kV, indicating a distribution-level interconnection, which is typical for projects up to 5MW and often more straightforward than transmission-level interconnections. The mention of a 138kV transmission line at 0.6 mi is intriguing, but the "NOT AVAILABLE" status is a critical flag. This needs immediate clarification from the utility (likely Ameren Illinois, given the location) – does "NOT AVAILABLE" mean it's not available for interconnection, or simply that detailed capacity data is unavailable? Assuming the 69 kV path is the primary, the estimated interconnection cost range for a 1-mile 69 kV line could be in the $1M - $3M+ range, depending on required upgrades at the substation and line construction complexity. The timeline for interconnection in Illinois, particularly with Ameren, can be lengthy, often 18-36 months for studies and construction, due to typical utility queue times. A pre-application meeting is essential to understand the utility's specific IX process and typical queue times for this region. The likely feeder configuration will need to be determined during the interconnection study process, but proximity suggests a direct tap or short radial extension.

4. Regulatory & Zoning Analysis

The Authority Having Jurisdiction (AHJ) is Unincorporated Knox County, IL. This simplifies the permitting process by dealing with a single county entity rather than multiple municipal layers. The provided zoning information presents a discrepancy: "Vacant Land - Rural/Agricultural-Vacant Land" and "Zoning (Regrid): M-2." M-2 typically denotes Heavy Industrial zoning, which is highly favorable for BESS projects, often allowing them by-right or with a streamlined Conditional Use Permit (CUP). If the zoning is indeed Rural/Agricultural, a Special Use Permit (SUP) or Conditional Use Permit (CUP) would almost certainly be required, which involves public hearings and discretionary approval. This discrepancy must be clarified immediately with the Knox County Planning Department. There are no known specific setback requirements provided, but typical BESS setbacks range from 50-200 feet from property lines and residential structures, which the 39.6-acre parcel should easily accommodate, especially with only 1.0 buildable acre. There are no known moratoriums or restrictions on BESS development in Knox County, IL, which is a positive sign. Reference to specific state regulations would include the Illinois Commerce Commission (ICC) for utility oversight and potentially the Illinois Environmental Protection Agency (IEPA) for environmental permitting.

5. IRA/ITC Incentive Analysis

The site's eligibility for Inflation Reduction Act (IRA) Investment Tax Credit (ITC) adders is a significant financial advantage. While the property is Not in an Opportunity Zone and Not a Low-Income Community, it *does* qualify as an Energy Community due to its designation as a Fossil Fuel Employment (FFE Area). This immediately qualifies the project for a +10% ITC adder on top of the base 30% ITC for BESS projects (assuming prevailing wage and apprenticeship requirements are met). If the site were also confirmed to be a brownfield, an additional +10% adder could apply. However, based on current data, the potential cumulative ITC adder percentage is +10%, resulting in a 40% ITC. This significantly enhances project economics and competitiveness.

6. BESS Score & Rationale

BESS Suitability Score: 80/100

• Location (18/20): Excellent public road access and "POI Onsite" are major positives, simplifying logistics and reducing off-site infrastructure needs. The large 39.6-acre parcel provides ample space for setbacks and future expansion, with a designated 1.0 buildable acre.
• Grid Access (23/25): Outstanding proximity to the Galesburg Monmouth Boulevard Substation (1 mile) and a 69 kV interconnection voltage are highly favorable. The close 138 kV line, despite its "NOT AVAILABLE" status, indicates robust grid infrastructure in the vicinity.
• Environmental (8/15): Significant unknowns regarding FEMA Flood Zone and Wetlands are critical deductions. While no critical habitat or pipelines are present, the brownfield proximity requires careful assessment for both risk and potential benefit.
• Regulatory (9/15): Unincorporated county jurisdiction is generally favorable, but the conflicting zoning information (Rural/Agricultural vs. M-2) creates uncertainty and requires immediate verification. The need for a SUP/CUP is likely if Rural/Agricultural, adding complexity.
• Incentives (13/15): Strong qualification as an Energy Community (FFE Area) provides a valuable +10% ITC adder, significantly boosting project economics. Lack of Opportunity Zone or Low-Income Community status prevents further adders.
• Buildability (9/10): Rated "Great" buildability with 1.0 identified buildable acres out of a large parcel is highly positive, suggesting minimal site preparation challenges and efficient use of land.

7. Key Risks & Mitigants

• Risk 1: Environmental Unknowns (FEMA Flood Zone & Wetlands)
  • Mitigant: Immediately commission a Phase I Environmental Site Assessment (ESA) including a preliminary wetland screen and obtain an official FEMA flood zone determination for the
