Our Temporary Power Design Services
Construction Load Calculations
We perform detailed load reviews based on site equipment—including hoists, cranes, welders, compressors, pumps, and temporary HVAC heaters—to size feeders accurately and prevent system overloads.
Single Line Diagram (SLD) Design
We engineer clear, code-compliant single line diagrams outlining the main service connection, overcurrent protection devices, sub-panels, and ground fault protection.
Utility Service Coordination
We handle the technical submission and coordination with local hydro utilities (Alectra, Hydro One, Toronto Hydro, etc.) to streamline service drop approvals and transformer placement.
Site Power Routing & Layout Plans
Detailed plans showing conduit routing, temporary service location, generator tie-ins, and distribution panel drops tailored to multi-stage construction workflows.
Crane & Heavy Equipment Power Systems
Dedicated electrical design for high-demand machinery such as tower cranes, concrete pumps, and passenger/material hoists.
Grounding & Safety Compliance
Comprehensive grounding grid and bonding details designed to meet strict ESA safety guidelines and protect on-site workers.

Our Design Process
Site Load Evaluation
We assess your site parameters, construction schedule, equipment list (trailers, cranes, tools), and available utility connection points.
Load Calculations & System Sizing
We calculate total connected and demand loads to select the appropriate temporary service size (e.g., 200A to 1000A+), transformers, and distribution panels.
Electrical Drawing Package
We draft sealed Single Line Diagrams (SLD) and site layout plans outlining all distribution equipment, conduit runs, and grounding specifications.
Utility & ESA Coordination
We submit technical documentation to the local hydro utility for service approval and provide complete drawings ready for ESA permit submission.
On-Site Inspection Support
We remain available throughout installation to address utility clarifications or mid-project adjustments as site needs evolve.
Frequently Asked Questions
Why do I need engineered drawings for temporary power?
Local utilities (e.g., Hydro One, Alectra) and the ESA require stamped Single Line Diagrams and load calculations for larger or commercial temporary power installations prior to granting connection approval.
How long does it take to get utility approval for temporary power?
Utility review timelines vary by region, but having complete, P.Eng.-stamped engineering drawings submitted early significantly reduces back-and-forth delays.
Can you design power for specialized equipment like tower cranes?
Yes. We perform specific motor-starting and voltage drop calculations for high-demand equipment like tower cranes, hoists, and site heating loads.
