SunZia Transmission Project

±525 kVHVDCNew Mexico & Arizona, USA

SANPEC describes a role spanning materials quality, global suppliers, logistics, engineering, quality, and supply-chain coordination during the project’s transition from HVAC to HVDC.

SANPEC source narrative

Integrated support for a complex high-voltage delivery program.

The SANPEC source content describes close collaboration with Pattern and Quanta to secure committed vendors, align delivery to the construction schedule and project specifications, and manage technical, quality, logistics, and supply-chain interfaces.

  • Materials quality and source-inspection coordination
  • Global supplier, logistics, engineering, quality, and supply-chain support
  • Vendor commitment and delivery alignment with construction schedule and specifications
  • HVAC-to-HVDC transition support, material type testing, and specialist process support as described by SANPEC

Engineering specifications

Each project record keeps clearly stated public facts distinct from information that needs client, partner, and SANPEC approval.

What a complete approved case study will include

SANPEC’s project template is intentionally evidence-led. Once approved, a full case study can describe the project context, technical and delivery challenge, SANPEC role, disciplines involved, quality and risk approach, source-approved outcomes, technologies, client information, and related research or capability.

Relevant SANPEC capabilities

  • Transmission and distribution engineering, design, and structural analysis
  • Testing and validation
  • Plant audits, source inspection, and QA/QC
  • Materials and project management
  • Logistics and construction support
  • Grid reliability and resilience planning
Image rights and gallery

Project-specific imagery is published only with approved rights and accurate attribution. Until then, SANPEC preserves the technical project record rather than presenting unrelated imagery as a project gallery.

Project record integrity

Source-listed project names, voltage, geography, system type, scope, client relationships, technologies, and outcomes are treated as separate approval fields. This prevents a portfolio card from implying more than the public record supports.
