Site Diligence Analysis: 604 S RAILROAD ST, Jo Daviess County, IL

As a senior BESS site evaluation analyst for Sunland America Corp, I have performed a comprehensive diligence analysis for the property located at 604 S RAILROAD ST in Jo Daviess County, Illinois. This analysis aims to identify key opportunities, risks, and next steps for developing a distribution-scale (≤5MW) or utility-scale BESS project at this location.

1. Site Access & Topography

The property address, 604 S RAILROAD ST, suggests proximity to a railroad, which is often indicative of industrial areas with established road infrastructure. However, the provided data for Road Access and POI Access is empty, which is a critical information gap. Given the Industrial (General) zoning, it is highly probable that the site benefits from paved, heavy-duty road access suitable for commercial and industrial traffic. This would typically facilitate the delivery of heavy equipment such as transformers, battery containers, and other large components. Without specific road quality data, we must assume a standard industrial road, but this requires immediate verification.

Regarding topography, Jo Daviess County, Illinois, is known for its rolling hills and bluffs, particularly near the Mississippi River. However, industrial-zoned parcels, especially those near railroads, are often located on flatter terrain or have been previously graded for industrial use. The 9.16 total acres (8.44397 Regrid acres) should provide sufficient space for a distribution-scale BESS. The absence of data for Buildability and Buildable Acres is a significant unknown. A preliminary desktop review of satellite imagery and a subsequent site visit will be crucial to confirm the actual terrain characteristics, identify any significant slopes, rock outcrops, or other features that could impact construction costs or require extensive grading. Access easements are currently unknown and must be investigated during the title review process to ensure unencumbered access for construction and operations.

2. Environmental Constraints

Several environmental factors require further investigation. The FEMA Flood Zone designation is currently Unknown, which is a critical data gap. BESS facilities must be sited outside of 100-year floodplains (Zone AE or A) or engineered with appropriate flood mitigation measures, which can add significant cost and complexity. Similarly, the presence of Wetlands is also Unknown. Wetlands identification and delineation are essential; if present, setback requirements (typically 50-100 feet) or permitting for impacts (e.g., Section 404 of the Clean Water Act) could significantly reduce buildable area or delay the project. The data indicates Critical Habitat and Protected Areas are None, which is a positive finding, reducing the risk of endangered species impacts. The site is also clear of Brownfield/Superfund sites within a 2-mile radius, which is good from a contamination risk perspective, though it means the project will not qualify for the IRA brownfield bonus adder. Pipeline Proximity is also favorable, with None within ~3 miles, mitigating safety concerns and setback requirements associated with high-pressure gas lines. The Chesapeake Bay Critical Area is correctly noted as N/A (non-MD), removing that specific regulatory hurdle. The absence of nearby Gas Wells is also a positive for safety and site stability.

3. Grid Infrastructure & Interconnection

The grid infrastructure at this site presents a significant opportunity. The Nearest Substation (UNKNOWN136979) is an exceptional 0.2 miles away. This extremely short distance is a major advantage, potentially leading to lower interconnection costs and a faster construction timeline for the gen-tie line. However, the Max Voltage for this substation is listed as -999999 kV, which is invalid data and requires immediate verification from ComEd. The Interconnecting Utility is confirmed as ComEd (Exelon), a large Investor-Owned Utility (IOU) with established interconnection processes. The IX Voltage is estimated at 12.47kV (ComEd distribution), indicating a distribution-level interconnection, suitable for projects up to 5MW. The absence of a Nearest Transmission Line within 3 miles further confirms a distribution-level approach.

Given the 0.2-mile distance to the substation and a 12.47kV distribution voltage, the likely interconnection voltage will be at 12.47kV. We recommend pursuing a distribution interconnection application. Interconnection costs are estimated to be on the lower end, potentially in the range of $200,000 - $500,000, primarily for a short gen-tie line, potential substation upgrades (depending on available capacity), and protection equipment. The timeline for ComEd's interconnection process can vary, but typical queue times for distribution projects in Illinois can range from 12-24 months for study completion and agreement execution, followed by 6-12 months for construction. The specific feeder configuration is unknown and will be identified during the initial interconnection study phase. Proximity to the substation often implies a robust feeder with potentially higher available capacity, but this must be confirmed through a pre-application report or initial screening study with ComEd.

4. Regulatory & Zoning Analysis

The Authority Having Jurisdiction (AHJ) is Unincorporated (county jurisdiction), meaning Jo Daviess County will be the primary permitting authority. This is generally favorable, as county-level permitting processes can sometimes be less complex or restrictive than those in incorporated municipalities. The current Zoning is Industrial (General), which is highly compatible with BESS development. Industrial zoning districts are typically designed to accommodate heavy industrial uses, including power generation and utility infrastructure, making BESS a strong candidate for a by-right use or requiring a relatively straightforward Conditional Use Permit (CUP) or Special Use Permit (SUP). A variance is unlikely to be required given the industrial designation.

Specific setback requirements for BESS in Jo Daviess County are currently unknown and must be investigated. These typically involve distances from property lines, residential structures, and public roads. Illinois does not have a statewide BESS siting law, so county ordinances will govern. We need to research Jo Daviess County's zoning ordinance for specific language regarding energy storage, utility facilities, or similar uses. Any known moratoriums or restrictions on BESS development in Jo Daviess County are unknown and should be a priority for initial regulatory outreach. The industrial zoning significantly de-risks the permitting pathway, but a detailed review of the county's Unified Development Ordinance is essential.

5. IRA/ITC Incentive Analysis

The site's eligibility for Inflation Reduction Act (IRA) Investment Tax Credit (ITC) adders provides a significant financial boost. The property is not located in an Opportunity Zone, so that 10% adder is unavailable. However, it is designated as an Energy Community due to its status as a Fossil Fuel Employment (FFE Area). This qualifies the project for a 10% ITC adder. The site does not qualify as a Low-Income Community, so that 10% or 20% adder is also unavailable. Assuming the project meets the prevailing wage and apprenticeship requirements (which is standard practice for Sunland America), the base ITC is 30%. With the Energy Community adder, the potential cumulative ITC adder percentage for this project is 40% (30% base + 10% Energy Community). This is a strong incentive that significantly enhances project economics.

6. BESS Score & Rationale

BESS Suitability Score: 78/100

• Location (15/20): The industrial zoning is excellent, suggesting good compatibility and potential for minimal community opposition. Proximity to a railroad implies good existing infrastructure. However, the lack of specific road access quality and buildability data, along with unknown topography, prevents a higher score.
• Grid Access (22/25): The 0.2-mile distance to the substation is outstanding, promising lower interconnection costs and faster timelines. ComEd is a known IOU. The primary deduction is due to the invalid substation voltage data and unknown available capacity, which are critical unknowns.
• Environmental (10/15): No critical habitat, pipelines, or brownfield status are significant positives. However, the unknown FEMA flood zone and wetlands presence are major gaps that could introduce significant risk and cost if unfavorable.
• Regulatory (13/15): Industrial (General) zoning in an unincorporated county is highly favorable for BESS development, likely allowing for a by-right or straightforward CUP/SUP pathway. The main deduction is for unknown specific county setback requirements and potential moratorium risks.
• Incentives (10/15): The 10% Energy Community adder is a strong positive, bringing the total ITC to 40%. The absence of Opportunity Zone and Low-Income Community adders prevents a perfect score, but a 40% ITC is still very attractive.
• Buildability (8/10): The 9.16 acres is ample for a distribution-scale project. Industrial zoning often implies relatively flat, buildable land. However, the complete lack of specific "Buildability" and "Buildable Acres" data, combined with unknown topography, requires a conservative score until a site visit and geotechnical assessment are performed.

7. Key Risks & Mitigants

1. Risk: Interconnection Capacity & Substation Voltage. The provided substation voltage data is invalid, and available capacity is unknown. There's a risk that the substation may not have sufficient capacity for a 5MW BESS without significant, costly upgrades, or that the actual voltage is not suitable for direct 12.47kV interconnection.
   • Mitigant: Immediately submit a pre-application request or an initial interconnection application to ComEd to obtain a System Impact Study (SIS) or Feasibility Study. Simultaneously, engage ComEd's engineering team to verify the substation's actual voltage and estimated available capacity.
2. Risk: Site Access & Buildability. Road access quality, specific buildable acres, and detailed topography are unknown. Poor access could hinder heavy equipment delivery, and challenging terrain could significantly increase civil engineering and construction costs.
   • Mitigant: Conduct an immediate site visit to assess road quality, access points, and preliminary topography. Follow up with a geotechnical survey and a detailed ALTA/NSPS land survey to confirm buildable area, soil conditions, and any potential easements.
3. Risk: Environmental Constraints (Flood Zone & Wetlands). The unknown FEMA flood zone designation and potential presence of wetlands could significantly impact siting, require costly mitigation, or reduce the usable land area.
   • Mitigant: Commission a Phase I Environmental Site Assessment (ESA) which includes a desktop review of FEMA flood maps and a preliminary wetlands assessment. If potential wetlands are identified, a formal wetlands delineation will be required.
4. Risk: Jo Daviess County Zoning & Permitting Specifics. While Industrial zoning is favorable, specific BESS setback requirements, fire code regulations, or other county-specific ordinances are unknown and could introduce unexpected challenges or costs.
   • Mitigant: Engage with Jo Daviess County Planning & Zoning Department to review the Unified Development Ordinance for specific BESS or utility-scale energy storage regulations, setback requirements, and the exact permitting pathway (by-right, CUP, SUP).
