⚡ 1480 RENAISSANCE DR

MEMORANDUM

TO: Sunland America Corp. Development Team

FROM: Senior BESS Site Evaluation Analyst

DATE: October 26, 2023

SUBJECT: Comprehensive Site Diligence Analysis for APN 09221100050000 (1480 Renaissance Dr, Park Ridge, IL)

1. Site Access & Topography

The subject property benefits from excellent logistical access, being situated in a developed commercial office park with public road frontage on Renaissance Drive. Its proximity to major transportation corridors, including Interstate 294 (Tri-State Tollway) less than a mile to the east, is a significant advantage for equipment and construction crew mobilization. The existing road network appears to be paved and well-maintained, likely designed to accommodate large delivery trucks.

Based on regional geography, the site's topography is presumed to be flat with minimal grade, which is ideal for BESS development as it drastically reduces earthwork and civil engineering costs. However, a formal topographic survey is required for confirmation. Access for heavy equipment, such as cranes for setting transformers and battery containers, appears feasible given the commercial nature of the surrounding area. A key unknown is the parcel's internal configuration and whether there are any tight turn radii, weight-limited culverts, or low-hanging utility lines on the immediate access route that could impede delivery of oversized loads. A significant concern is the discrepancy in listed acreage (35.02 acres vs. 2.97 acres from Regrid for the specific APN). If the 2.97-acre figure is correct, site access and construction laydown areas will be constrained.

Action Item: A title search must be conducted to identify any access, utility, or other restrictive easements that could encumber the buildable area. A site visit is required to verify delivery routes from the interstate to the parcel entrance.

2. Environmental Constraints

The environmental profile of the site presents several critical unknowns that must be resolved.

• FEMA Flood Zone: The designation is currently unknown. Any location within a 100-year floodplain (e.g., Zone A, AE) would introduce significant design challenges, requiring elevated foundations for all equipment, higher insurance premiums, and a more complex permitting process. This is a potential fatal flaw that must be investigated immediately via FEMA's Flood Insurance Rate Maps (FIRMs).
• Wetlands: Presence is unknown. A desktop screening using the National Wetlands Inventory (NWI) is the first step. If potential wetlands are identified, a formal wetland delineation will be necessary. The presence of jurisdictional wetlands would trigger significant setbacks (typically 50-100 feet) and could severely limit the buildable envelope on a smaller, 2.97-acre parcel.
• Habitat & Species: The data indicates no critical habitat on site, which is a positive. However, a query of the USFWS IPaC system is recommended to screen for any potential impacts to threatened or endangered species in the project vicinity. Given the developed nature of the area, significant risk is considered low.
• Brownfield/Superfund: The property itself is not listed as a brownfield, meaning it is unlikely to qualify for the 10% IRA brownfield tax credit adder. The presence of a superfund site within two miles warrants inclusion of soil and groundwater contamination assessment within the scope of a Phase I Environmental Site Assessment (ESA) to ensure no contaminant migration poses a risk to the subject parcel.
• Pipeline Proximity: The absence of major gas pipelines within a three-mile radius is a significant safety and design advantage, eliminating concerns related to pipeline setbacks and explosion risk assessments.

3. Grid Infrastructure & Interconnection

Interconnection is the most significant technical and financial variable for this project. The designated utility is Commonwealth Edison (ComEd), which operates within the PJM RTO.

• Substation/Point of Interconnection (POI): The nearest substation is not identified in the provided data, a major information gap. Desktop analysis using satellite imagery suggests a potential ComEd substation approximately 0.7 miles east of the site, on the other side of I-294. The viability, available capacity, and thermal rating of this substation are completely unknown.
• Transmission Access: A 138kV transmission line is located 1.5 miles away. For a distribution-scale project (≤5MW), interconnecting at transmission voltage would be prohibitively expensive and complex. This option should be considered non-viable.
• Recommended Interconnection: The only feasible path is a distribution-level interconnection, likely at 12.47kV or 34.5kV, to a local ComEd feeder. The specific feeder route and its capacity must be identified through a formal pre-application with ComEd.
• Cost & Timeline Estimate: This is highly speculative. Assuming a POI at the substation 0.7 miles away, interconnection costs could range from $750,000 to over $2.5 million, depending on whether the connection requires undergrounding, highway bores, and the extent of substation upgrades. The PJM interconnection queue process is notoriously long; a realistic timeline from application to commercial operation could be
