When you begin a new construction project in the Phoenix Metro area, one of the first challenges you face is getting power to the site. Crews need electricity for tools, lifts, trailers, and equipment long before the building is ready for a permanent utility connection. This creates a gap that every general contractor must plan for: the period between breaking ground and the moment SRP or APS turns on permanent power.
Understanding the difference between temporary power and permanent power is essential for keeping your project on schedule and avoiding costly delays. Here is what Phoenix builders, developers, and project managers need to know.
What Is Temporary Power for Construction Sites?
Temporary power provides electricity to a site before the permanent utility service is installed. This setup is designed specifically for construction environments where power needs change as the project moves forward.
A temporary power system in Phoenix often includes:
- Generators or utility-fed temporary panels
- Distribution panels and sub-panels
- Cables and conduit
- Posts, pedestals, and protective framing
- Grounding and safety systems
- Ongoing maintenance, refueling, and inspections
Temporary power allows crews to begin work on day one, even when the property does not yet appear in SRP or APS systems.
Why Permanent Power Takes Time
Permanent utility power is typically not available until very late in construction. SRP and APS require the building to be structurally complete and all electrical gear to be fully installed and inspected before they will turn on power to the property.
Permanent power typically cannot be activated until:
- Transformer pads and conduit systems are installed
- The metering system passes inspection
- The building’s panels are complete and labeled
- The structure is weatherproof and secure
- All underground inspections are approved
This means most projects rely on temporary power for several months.
Why You Cannot Rely on Generators Alone
Generators are helpful, but a generator by itself is not a complete temporary power system. Large commercial projects often require multiple distribution points, dedicated circuits, and proper grounding. Heavy equipment, HVAC startup, and lift stations need more power than a single generator can safely supply.
A proper temporary power plan prevents overloaded circuits, unsafe wiring, and unnecessary downtime.
How Temporary Power Helps You Avoid Delays
Every day without power on a construction site costs money. Crews cannot work, equipment sits idle, and schedules start to slip. In Phoenix, delays in temporary power are one of the most common causes of early project slowdowns.
A complete temporary power system:
- Keeps crews working from day one
- Reduces dependence on small portable generators
- Supports heavy equipment and multi-trade operations
- Allows construction to continue while waiting for SRP or APS to turn on service
- Prevents shutdowns from overloaded or unsafe wiring
- Keeps your schedule aligned with project milestones
When to Plan for Temporary Power
For most projects in the Phoenix area, planning should begin early. Ideally, temporary power is designed before the first crews arrive on site. Builders who coordinate temporary power during preconstruction avoid delays caused by utility timelines that do not match construction timelines.
Working With a Commercial Electrical Contractor
The best approach is to work with a commercial electrical contractor that specializes in temporary power for construction. At Allied Electric Technology, we coordinate with SRP and APS, design the system, install all equipment, and maintain it throughout the project. Our goal is to keep your site powered and productive while we prepare for the permanent utility connection.
