⚡ 1480 RENAISSANCE DR

1. Site Access & Topography

Road Access & Equipment Delivery: The subject property is located at 1480 Renaissance Drive in a developed commercial office park in Park Ridge, IL. Access is listed as public, and satellite imagery confirms the site is served by a modern, paved, multi-lane road. This quality of access is highly favorable for construction, suggesting that standard and heavy-haul trucks can reach the site with ease. The proximity to major highways (I-294) is a logistical advantage for the delivery of large components like battery containers, pad-mount transformers, and switchgear.

Terrain & Buildability: The topography in Cook County is characteristically flat, a remnant of glacial activity. We can assume the site has minimal grade change, which significantly reduces earthwork and civil engineering costs. The primary buildability concern is not topography but the existing land use as a multi-story office building and associated parking lots. Development would require demolition and removal of existing structures and pavement. The listed parcel size discrepancy (35.02 acres vs. 2.97 acres from Regrid for the specified APN) is a critical ambiguity. A 2.97-acre site is adequate for a 5MW BESS, but confirmation of the exact parcel boundaries and net buildable area via an ALTA survey is essential.

Heavy Equipment & Easements: Access for cranes, container delivery trucks, and concrete trucks appears excellent. However, a detailed logistics plan must verify turning radii from Renaissance Drive onto the specific project site and check for any overhead utility lines that could obstruct crane operations. A full title report is required to identify any existing utility easements (e.g., for gas, water, sewer, or communications) that may cross the property and sterilize portions of the buildable area. No immediate access easement concerns are apparent given the direct public road frontage.

2. Environmental Constraints

FEMA Flood Zone & Wetlands: The FEMA flood zone status is currently Unknown. This is a critical data gap. If the site is located within a 100-year floodplain (e.g., Zone AE), all equipment pads and control houses would need to be elevated above the Base Flood Elevation (BFE), adding significant cost and complexity. An immediate review of FEMA's Flood Insurance Rate Maps (FIRMs) is a high-priority next step. Similarly, the presence of wetlands is Unknown. A desktop screening using the National Wetlands Inventory (NWI) is required, to be followed by a formal wetland delineation if the screening indicates potential jurisdictional wetlands. The presence of wetlands could impose significant setbacks or require costly mitigation, severely impacting site layout.

Brownfield/Superfund Status: The report notes one Superfund/Brownfield site within a two-mile radius. This does not mean the subject property is contaminated, but it raises the risk profile for the area. A Phase I Environmental Site Assessment (ESA) is mandatory to establish an environmental baseline and identify any Recognized Environmental Conditions (RECs). This is a double-edged sword: if the site itself qualifies as a brownfield (e.g., due to prior industrial use or contamination), it could unlock the 10% IRA Brownfield ITC adder, turning a potential liability into a significant financial advantage. If it is contaminated but does not meet the specific IRA definition, it represents a pure cost and liability risk.

Other Considerations: The site has no identified critical habitats or protected areas, which is a significant de-risking factor. Proximity to pipelines is not a concern, with none identified within a three-mile radius, eliminating the need for specialized safety studies or setbacks related to pipeline right-of-ways. The site is not in the Chesapeake Bay Critical Area.

3. Grid Infrastructure & Interconnection

Substation & Transmission Infrastructure: This is the most significant unknown for the project. Data on the nearest distribution substation (distance, voltage, capacity) is missing. Identifying the local Commonwealth Edison (ComEd) substation and the specific distribution feeder serving the area is the highest priority diligence item. The presence of a 138kV transmission line 1.5 miles away is noted, but this is not a viable Point of Interconnection (POI) for a distribution-scale (≤5MW) project. The cost of a 1.5-mile transmission line extension and a new project-specific substation would be prohibitively expensive (likely >$10M).

Interconnection Strategy & Costs: The only feasible path is a distribution-level interconnection. We recommend targeting a 12.47kV or 34.5kV feeder, which are common ComEd distribution voltages. The interconnection cost is highly dependent on the distance to a viable 3-phase feeder and the available capacity at the local substation.

• Best Case: A feeder with adequate capacity runs adjacent to the property. Cost could be in the $500k - $1.5M range for switchgear, protection, and a short line tap.
• Worst Case: The nearest feeder lacks capacity, requiring a new dedicated feeder from the substation or significant substation upgrades (e.g., a new breaker bay). Costs could easily exceed $3M - $5M+.

4. Regulatory & Zoning Analysis

Jurisdiction & Zoning Compatibility: The Authority Having Jurisdiction (AHJ) is the City of Park Ridge. The property is zoned "O" - Office District. Battery Energy Storage is not a typical use in a commercial office zone and is almost certainly not a use permitted "by-right." The current land use
