Mega‑campus filings validate large‑acreage, interconnect‑ready campus theses

Policy Support

Pro‑growth permitting posture supportive of mission-critical infrastructure (in contrast to other submarkets that have introduced restrictions on data center activity)

Syndicated Capital Activity

Investor‑led West Valley land activity. Programmatic land aggregation and JV structures are becoming the norm and institutional capital is underwriting at scale

Multiple Development Pathways

Highest-and-best-use optionality as market conditions evolve

The site’s flexibility and infrastructure positioning create multiple value-creation pathways — with data center development as the primary opportunity, supported by utility proximity, location outside city limits, and early-mover positioning as the corridor scales

Hyperscale Data Center

Phased multi-hundred MW / GW campus with integrated prime-power paired with natural gas and/or renewables — leveraging favorable power capacity and queue dynamics

Renewable Energy / BESS

Utility-scale solar and battery energy storage systems with direct grid interconnection capabilities and co-location opportunities with data center operations

Manufacturing / Logistics

Large-scale manufacturing and distribution/logistics facilities capitalizing on strategic access and proximity to major highway E-W corridors I-10 & I-8, and the future I-11 corridor N-S

Master Planned Community

Residential, retail and recreational development leveraging existing CPA entitlements for Insignia Estates with 2,091 dwelling units, retail and supporting amenities

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

APS 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.

Natural Gas Infrastructure - Capacity Expansion Underway

Pipeline Access

  • Proximity to a major pipeline corridor, including Transwestern/El Paso infrastructure.
  • APS & SRP have committed capacity on Transwestern’s Desert Southwest expansion.

Capacity Growth

  • Expansion adds ≥2.3 Bcf/d by 2029, aligned with rising data-center power demand.
  • Provides incremental headroom for new firming resources and large-load reliability as the region scales.

Reliability & Dispatchable Support

  • Supports evaluation of firm, dispatchable generation strategies that complement solar/BESS.
  • Provides a dispatchable-power pathway for resilience planning and peak-season constraint mitigation.

On-Site Generation & Interconnect Optionality

  • Proximity supports evaluation of behind-the-meter solutions, including reciprocating engines, LM-class turbines, CHP, and BESS hybrids, for phased power, resiliency, and black-start planning.
  • Subject to buyer diligence, utility coordination, air permitting, and applicable regulatory approvals.
