SUBJECT: Comprehensive Site Diligence Analysis for "Project O'Hare"

PROPERTY: 1480 RENAISSANCE DR, Park Ridge, Cook County, IL (APN: 09221100050000)

RECOMMENDATION: MAYBE

This report provides a comprehensive due diligence analysis for the potential development of a distribution-scale (≤5MW) Battery Energy Storage System (BESS) at the subject property. The site presents a compelling opportunity due to its location within a high-load commercial area and qualification for a key IRA tax incentive. However, significant regulatory and environmental risks must be addressed before committing further capital. The final recommendation is MAYBE, contingent on favorable outcomes from the initial due diligence steps outlined below.

1. Site Access & Topography

• Road Access & Feasibility: The site has excellent access. It is located in a modern office park with direct frontage on Renaissance Drive, a wide, paved public road. The property is situated less than a mile from major arterial roads (Higgins Rd) and interstate highways (I-294), which is ideal for logistics.
• Terrain Characteristics: As is typical for the Chicago metropolitan area, the terrain appears to be flat with minimal grade. This significantly reduces earthwork and civil engineering costs, simplifying foundation design for battery containers, inverters, and the main power transformer.
• Heavy Equipment Access: Access for heavy equipment, including mobile cranes for transformer placement, flatbed trucks for battery container delivery, and concrete trucks, appears to be straightforward. The existing road network is designed to handle commercial vehicle traffic. No immediate constraints are apparent from a desktop review.
• Easement Concerns: Requires Verification. As a developed commercial parcel within a larger office park, there is a high probability of existing utility easements (power, water, sewer, data) and potentially cross-access easements. A title report and ALTA survey are required to identify any encumbrances that could restrict the buildable area for the BESS compound.

2. Environmental Constraints

• FEMA Flood Zone: The FEMA flood zone designation is listed as "Unknown." This is a critical data gap. The property is located approximately 1.5 miles east of the Des Plaines River, elevating the potential risk. Siting critical infrastructure in a Special Flood Hazard Area (SFHA) would introduce significant design complexity, insurance costs, and potential permit denial. A FEMA FIRMette must be obtained immediately to confirm the site's status.
• Wetlands: The presence of wetlands is "Unknown." A desktop screening using the National Wetlands Inventory (NWI) is a necessary first step. Any potential wetlands would trigger significant state (IEPA) and federal (USACE) setbacks and permitting requirements, potentially rendering the site undevelopable. A formal wetland delineation will be required if the desktop screening indicates a risk.
-
• Critical Habitat / Endangered Species: The data indicates no critical habitat or protected areas on site, which is expected for a developed commercial parcel in a dense suburban area. This is considered a low-risk item, but should be confirmed with a desktop environmental review.
• Brownfield/Superfund Status: The record notes one Superfund/Brownfield site within two miles. This presents both a risk and an opportunity.
  • Risk: The proximity of a contaminated site could indicate a risk of migrating contaminants, which must be assessed via a Phase I Environmental Site Assessment (ESA).
  • Opportunity: If the subject property itself can be classified as a brownfield site (e.g., due to prior use or perceived contamination), it would qualify for the 10% IRA Brownfield Tax Credit Adder. This requires further investigation.
• Pipeline Proximity: No major gas transmission pipelines are identified within a 3-mile radius, mitigating risks associated with pipeline setbacks and safety protocols.

3. Grid Infrastructure & Interconnection

• Nearest Substation: Requires Verification. While the provided data is incomplete, a desktop review using satellite imagery identifies the ComEd Park Ridge Substation located approximately 0.5 miles east of the property, just across I-294. This proximity is highly favorable and suggests a strong potential for a cost-effective interconnection. The substation's voltage class and available capacity are critical unknowns that must be confirmed with the utility.
• Transmission Line Proximity: A 138kV transmission line is 1.5 miles away. This is not a viable Point of Interconnection (POI) for a distribution-scale project due to the excessive cost and complexity of a transmission-level tap. The project strategy must focus on a distribution-level interconnection.
• Recommended Interconnection Voltage: The most likely and cost-effective interconnection will be to a local Commonwealth Edison (ComEd) distribution feeder, likely operating at 12.47kV or 34.5kV.
• Estimated Cost & Timeline: Assuming a POI on a distribution line adjacent to the site with sufficient capacity, interconnection costs could range from $750,000 to $2,000,000. However, if the feeder requires significant upgrades or work is needed inside the substation, costs could escalate substantially. The interconnection process is managed through the PJM RTO queue, which is currently experiencing significant backlogs. The timeline from application to an Interconnection Service Agreement (ISA) could realistically be 18-36 months.
• Utility & Feeder Configuration: The interconnecting utility is Commonwealth Edison (ComEd). Satellite imagery shows overhead distribution lines running along Renaissance Drive and Higgins Road, which are the likely targets for interconnection. A formal pre-application with ComEd is essential to identify the specific feeder and available capacity.
