Multiple development pathways preserve option value while positioning for the highest and best use as market conditions evolve.
What Makes This Site Different
Current MPC Entitlements
Existing CPA & PAD/RUPD for 2,091 dwelling units plus supporting retail, educational, and recreational uses already approved. County-level pathway toward alternative-use overlay permissions supporting data center and industrial development.
Outside AMA Water Flexibility
No Active Management Area restriction supports greater water-sourcing and planning flexibility relative to AMA-restricted locations.
500 kV Proximity
Situated in the APS Cotton Transmission Corridor, with dual 500 kV lines immediately north and the Jojoba 500 kV substation approximately 5 miles east, supporting large-load interconnection evaluation.
Power Delivery Structure
Public power access via the Electrical District model (ED8) supports competitive large-load solutions and a distinct capacity, structuring, and pricing framework versus constrained IOU queue/tariff models. *
Gas Adjacency
High-pressure natural gas pipeline proximity supports evaluation of optional prime-power and behind-the-meter generation strategies. *
Fiber Expansion
Lateral connectivity expansion via ADOT's planned fiber route on SR-85 (linking I-10 and I-8 / Gila Bend).
* Recent ACC siting cases illustrate that public power districts can act as critical intermediaries for large data-center-linked generation projects, potentially offering regulatory clarity, queue efficiency, and political defensibility. Insignia’s ED8 location may offer analogous early-mover advantages, subject to project-specific utility, regulatory, and interconnection diligence.
Site Location
Infrastructure Proximity
Site Features
Visibility & Access
Prime frontage on Old U.S. Highway 80 with canal at southern edge providing natural boundaries. Potential controlled access points support secure perimeter planning for sensitive operations.
Setbacks & Buffers
538 acres allows generous setbacks, security standoff zones, and phased expansion capabilities. State Trust Land to the north provides a low-access buffer between the site and the power corridor.
Surrounding Uses
Compatible adjacent uses including agriculture, renewable energy projects, emerging industrial and logistics facilities, and regional utility infrastructure create a supportive development environment.
Topography & Soils
North block features native desert terrain while south block contains historic agricultural fields and a well. Favorable topography for large pad development, subject to geotechnical confirmation.
Ownership & Control
Six contiguous parcels under single ownership, reducing assemblage complexity.
Future I-11
Proximity to north–south freight route between Phoenix, Las Vegas, and Mexico.
Power Infrastructure - Interconnection
Interconnection Capabilities Analysis (K. R. Saline & Associates, 8/28/2025)
The site is strategically located between the Palo Verde Hub and Gila River Generating Station, within Arizona’s 500 kV loop.
Current Transmission / Distribution
- Possible 500 kV connection points include tapping one or both Jojoba–Hassayampa 500 kV lines to the north of the site.
- Alternative: direct interconnection at the Jojoba 500 kV substation ~5.3 miles east.
- Deliverability from a diverse set of generation resources (nuclear, solar/storage, wind, gas).
Line Ratings & Headroom
- Low base-case loading indicated on the referenced 500 kV lines; supporting large-load interconnection evaluation.
- Double-circuit option provides added redundancy for deliverability planning.
(Specific ratings and base-load metrics available upon request)
Electrical Hubs & Future Deliverability
Cotton Transmission Corridor project: 100+ miles of new and rebuilt 230 kV / 500 kV transmission lines interconnecting multiple existing and new substations; strengthening deliverability and expanding interconnect pathways for large-load programs.
