Utility Power Distribution Design

Power Distribution Design & Utility Engineering

We provide complete overhead and underground engineering services tailored to electric power utilities. From system modeling and commercial/industrial expansions to updating utility specifications, our team delivers safe, reliable and cost effective solutions.

Core Services

• Residential Connections: Complete distribution design for typical single-family developments (URD), multi-family housing complexes, and urban infill projects—including transformer sizing, trenching layouts, and service drops.

• Underground Industrial Distribution (UID): Specialized primary and secondary underground distribution for high-demand industrial facilities, heavy-duty duct banks, three-phase transformer pads, and switchgear configurations.

• Commercial Services: Dedicated primary/secondary service connections and capacity upgrades for commercial and retail facilities.

• Overhead & Underground Engineering: Full-scope distribution design, line routing, pole loading, duct banks, vault layout, and overhead-to-underground transitions.

• Utility Standards Updates: Authoring and modernizing utility construction standards, framing specifications, and line design guidelines to meet current NESC and IEEE codes, and the latest utility industry standards and practices.

• Grid Hardening & Joint-Use: Storm-proofing upgrades, vintage asset replacements, line re-conductoring, and make-ready engineering for telecom/broadband attachments.

Software & Technical Tools

We utilize industry-standard software to ensure accurate structural integrity, spatial modeling, and code compliance across all projects:

Structural & Asset Modeling Software

• PLS-POLE: Deep-dive structural analysis and component-level non-linear modeling for wood, steel, and concrete pole structures.

• SPIDACalc: Pole loading analysis, non-linear structural evaluation, and high-volume joint-use make-ready assessment.

Line Design & Cable Stringing Software

• PLS-CADD: 3D line routing, terrain modeling, clearance analysis, and spatial geometry optimization.

• SPIDA Silk: Sag/tension analysis, wire clearance verification, and overhead line design within the SPIDA software suite.

• SAG-10: Precise conductor sag, tension, and stringing calculations under maximum thermal and weather loading conditions.

Standards & Compliance: All designs adhere strictly to NESC, IEEE, and client-specific utility criteria.
