Need juice on-site fast before your permanent hookup’s ready? Skip the headaches—here’s exactly how to get temporary power without the runaround.
Quick Fix: Call your local utility’s temporary power desk (or fire up their online portal), ask for a 480V/200A overhead tap, double-check the pole height (36–40 ft), agree to the Wayleave fee (usually 1–4 % of site value), lock in an inspection within 5–7 days, and cough up the $1,000–$5,000 hookup fee. Two weeks later? You’ve got power.
What’s the deal with temporary power?
Temporary electrical power at a job site or event isn’t just slapping a generator in the corner. We’re talking utility-grade juice that has to meet OSHA and NFPA 70 (NEC) wiring rules. The power can come from an overhead tap on a nearby pole, a mobile transformer, or a trailer unit. Permits, inspections, and safety clearances? Non-negotiable—skip them and you’re begging for fines or blackouts.
How do you actually make this happen?
- Crunch the numbers first. List every gadget: lights, tools, pumps, offices, trailers. Add up the amps—then aim for 80 % of your panel’s max rating. A quick rule: 480V/200A handles a small site; 480V/400A is better for mid-size projects.
- Dial up the utility. Hit their “temporary power” or “construction power” menu online or call (800) 555-TEMP (your utility’s direct line). Hand over:
- The site address and GPS pin
- Requested voltage (usually 480V 3-phase)
- When you need it and for how long
- A load schedule sheet (they’ll email a template)
- Sign the Wayleave contract. If the tap’s on private land, the utility sends a Wayleave agreement for 1–4 % of the property’s value. E-sign it—it lasts 6–12 months and often auto-renews.
- Pay the hookup fee. By 2026, expect $1,000–$5,000 to cover labor, gear, and the city/county inspection. Some utilities bundle the pole ($360–$620) and meter base ($60–$620) right into the quote.
- Get the inspection on the books. The utility sets up the city electrical inspector within 5–7 business days. Clear the site, slap a “TEMPORARY CONSTRUCTION SERVICE” label on the panel, and wait.
- Flip the switch. Once the inspector slaps their approval tag on it, the utility flips the tap live. Circle the date—temporary power usually shuts off 90 days after your permanent service kicks in.
What if the utility route fails?
- Go generator. Rent a 40 kW trailer unit ($400–$600/day) for sites where overhead taps aren’t an option. Ground it per OSHA 1926.404 and use 60 A twist-lock cords.
- Bring in a mobile transformer. Need 480V-to-120/208V? Companies like Sunbelt or United Rentals drop off a 75 kVA unit ($800–$1,200/week) with built-in breakers. Plug it in and you’re live within 24 hours.
- Ask for a “direct tap.” If your site sits within 200 ft of an existing pole, request this instead of a new pole. Savings run $1,500–$3,000.
Any tips to avoid future headaches?
- Permits first, always. Pull the electrical permit before you order materials—some insurers won’t cover work that starts without it.
- Label like your life depends on it. Tag every panel, box, and cable with “TEMPORARY – DO NOT REMOVE” to prevent accidental disconnections.
- Time the disconnect right. Schedule the temporary service to end at least 30 days before your certificate of occupancy; that buffer keeps final inspections smooth and avoids last-minute rush fees.
- Keep a backup handy. A 10 kW inverter generator ($1,200) on-site covers critical loads during outages and runs eight hours on eight gallons of fuel.
- Save the load sheet. Hang onto the signed PDF from the utility—it’s your proof if an inspector questions your breaker sizes.
