TL;DR
Temp power in Connecticut has no single statewide price. You pay for a Chapter 393 electrical license if you do the work, a local permit, the pole or generator, utility energizing, inspections, and fuel or kWh. EIA ranks Connecticut electricity among the most expensive in the country. Confirm DCP fees and utility rules. Do not trust a national average.
How much does temp power cost in Connecticut?
There is no official statewide temp power price in Connecticut. Your cost is the sum of license paper if you perform electrical work, a municipal permit, materials or a rental generator, utility connection work, inspection, and either diesel or metered kWh. EIA puts Connecticut retail electricity among the highest in the United States.[8] Confirm every current fee with DCP, your town, and the utility. Nobody publishes a clean dataset of typical temp pole invoices here.
People want one number. You will not get one from PURA, DCP, or the Office of the State Building Inspector. Those agencies do not sell a statewide temp service package.
What you can know is the stack. State law sets the license path. Your town sets the permit fee. Your serving utility sets the connection rules and the tariff. The supply house sets the pole, meter socket, and panel price. Fuel tracks the diesel market. Labor tracks what licensed electricians actually charge in that county.
I would not use a national blog average to bid a Connecticut site. High kWh prices punish long-running temp services. A two-week pole on a dry lot is a different job than a 14-month school addition with temp heat. Price the duration.
If you want a feel for how other states break this out, the writeups on temp power cost in California and temp power cost in Delaware show the same stack with different boards and different utility desks.
Waste of money: prepaid nationwide temp power quotes that ignore Connecticut license law and ignore which utility actually serves the street.
Do you need a license for temp power in Connecticut?
Yes. If you engage in, practice, or offer electrical work in Connecticut, you need the right Chapter 393 license unless a statutory exemption applies.[1][2] Temporary construction power, temp lighting, and generator hookups are electrical work. They are not a side hobby the state ignores.
Connecticut General Statutes section 20-334 says, "No person shall engage in, practice or offer to perform the work of any occupation licensed or registered pursuant to this chapter in this state unless such person has first obtained a license or certificate of registration for such occupation as provided in this chapter or is exempted from such requirements under section 20-340."[2]
Read the exemptions in section 20-340 before you assume you qualify.[3] Public service company employees doing company work, some manufacturing plant employees, and a few other listed classes sit in that section. A contractor offering temp power connecticut service to a builder is not in that group.
The Department of Consumer Protection lists the electrical work practitioner classes, including the E-1 unlimited electrical contractor and the E-2 unlimited electrical journeyperson.[5] Confirm the current class you need on that DCP page. I am not going to invent today's application fee or exam fee. Those numbers move. Pull them from DCP and the exam vendor DCP names the week you apply.
Doing the work unlicensed is how you get a stop-work order, a failed inspection, and a utility that will not set the meter. Cheap, until it is not.
How long does temp power take in Connecticut?
There is no statewide clock for temp power in Connecticut, and I will not invent one. A licensed crew can install a simple temp pole in a day once the permit is in hand. Inspection and meter set can follow in a few business days if the site is ready and no line work is needed. A line extension, a new transformer, or a slow building department can stretch that into weeks or longer. Confirm with the building official and the utility. No approval or timing guarantees.
License time is a different clock. A registered electrical apprenticeship in Connecticut is a multi-year program. Confirm current hour standards with the Connecticut Department of Labor apprenticeship office.[12] You do not become an E-1 between Monday and Friday.
Utility time depends on whether the service exists at the lot line. Eversource and UI both run builder and new construction desks.[14] If they have to set a pole or pull primary, you are on their construction calendar, not yours.
Town time depends on separate building departments, each with its own intake. I have no honest average. Call the town where the work sits. Ask how they want the electrical permit filed and how they schedule the temp service inspection.
If the job is a generator, add lead time for the rental fleet, fuel delivery, and any DEEP air paper that applies to that engine.
Do not promise an owner a Friday energize date until the inspector and the utility have both said the site is clear.
What actually makes up a Connecticut temp power bill?
A Connecticut temp power bill is a pile of line items from different desks. Mix them up and your estimate is fiction.
| Cost line | Who sets it | Confirm with |
|---|---|---|
| License and exam | State | DCP electrical work practitioners page |
| Building or electrical permit | City or town | Local building official |
| Utility connection and tariff | Serving utility | Eversource, UI, or the municipal utility |
| kWh, demand, deposits | Utility tariff under PURA | Current tariff and account rep |
| Pole, meter socket, panel, cord | Market | Local supply house quote |
| Sales and use tax | State statute | CGS 12-408 and the DRS sales tax page |
| Generator air paper | State | DEEP air permits staff |
| Labor | Market, or prevailing wage on covered public work | BLS OEWS table and CT DOL |
Connecticut General Statutes section 12-408 is the sales and use tax statute. Reread the rate currently printed there before you add tax to a materials bid.[11] Most gear you buy at a supply house is taxable. I would not assume a rental is tax-free. Ask DRS or your accountant.
Permit fees are local. Two towns ten miles apart can charge different amounts for the same 200A temp service. That is normal here. It is also why a statewide "average permit" is a made-up comfort number.
Utility money is more than the meter. You may see a deposit, a contribution if they extend facilities, and then the tariff for energy and any demand. PURA lists the electric companies and is the place to start when you need the official utility map, not a Facebook comment.[10]
Labor is the line people lowball. BLS publishes Connecticut electrician wages on the state OEWS page.[13] Read the current mean and median before you guess. On a public school or other covered public work, prevailing wage rules can apply. Confirm that with Connecticut DOL. I would rather over-ask than get a wage complaint six months in.
Is utility temp service cheaper than a generator in Connecticut?
It depends on how long the site runs and whether the utility can actually reach you. For a months-long build on a street that already has secondary, a metered temp service usually wins on fuel and babysitting. For a two-week punch-list, a wet lot with no nearby secondary, or a night event, a generator can cost less even when diesel is ugly.
Connecticut kWh prices work against long generator runtimes and against sloppy temp heat on a metered pole. EIA's Connecticut electricity profile is the public benchmark I would open before I pick a path.[8] Pull the current cents per kWh on that profile. Then price diesel for the same weeks. Nobody has good paired invoice data for this; the closest public figures are those EIA prices and whatever quote your rental house prints this week.
Utility temp service still has fixed costs. The pole or pedestal, the listed meter socket, grounding, the permit, the inspection, the account. If those fixed costs sit on a four-day job, the generator may look smarter.
A generator is not a license holiday. The hookup, distribution, and 480V tails are still electrical work under Chapter 393.[1] OSHA still wants GFCI protection or an assured equipment grounding conductor program on a construction site.[6]
I would run both numbers on anything longer than a month. I would not pick a generator just to dodge a building official. That dodge fails the first time someone asks who energized the panel.
For a sense of how high-cost states vs sunbelt states shift this math, compare this page with temp power cost in Florida and temp power cost in Arizona.
What permits and inspections do you need for temp power in Connecticut?
You need a local permit before you build or alter, and temporary electrical gear sits in that world. Connecticut General Statutes section 29-263 is the core permit statute. It says no building or structure shall be constructed or altered until an application has been filed with the building official and a permit issued, with the exceptions that section and the State Building Code actually name.[4] Confirm how your town applies that language to a temp pole or a generator set. Do not guess from a forum post.
The electrical rules you build to are the Connecticut State Building Code, which adopts the National Electrical Code edition named by the Office of the State Building Inspector.[9] Temporary installations live in NEC Article 590 in that adopted edition. Confirm the edition currently in force on the OSBI page before you argue with an inspector.
Typical path, in plain order. File the permit. Install to the code and to the utility spec. Call for the municipal electrical inspection. After the sticker or sign-off the town uses, the utility sets the meter and energizes. If any of those steps is missing, you wait.
Some towns also want a contractor registration on file, a copy of the E-1, and an insurance certificate before they will issue. That is a local rule, not a DCP license. Budget a trip to the building department.
Inspections are not optional theater. The utility will not bless a can that failed. Rework costs more than doing the grounding electrode and the weatherhead height right the first time.
How much should you budget for labor and materials?
Budget from quotes, not from a national kit price. Materials for a single-phase temp service are a meter socket, disconnect or panel, mast or pedestal, conductors, grounding electrode system, in-use covers, and GFCI protection for 15A and 20A receptacles. Three-phase and 480V add listed cam-type connectors, the right overcurrent devices, and a lot more care.
I will not invent a supply-house total. Copper, gear, and lead times move. Call two Connecticut houses and get dates with the dollars.
Labor should start from the BLS Connecticut electrician table, then add truck time, inspection wait, and return trips.[13] A "half-day pole" estimate dies when the grounding electrode is frozen, the utility wants a different socket, or the inspector is only on site Thursdays.
On covered public work, check prevailing wage before you sign. That can change the labor line more than the price of a meter can.
Waste of money: buying a 400A three-phase temp setup for a garage addition that needs 100A. Also wasteful: the cheapest used meter enclosure that the utility then rejects.
What I would do. Get the serving utility's information and requirements first.[14] Buy only gear that document accepts. Hire an E-1 if you are not one. Price a second inspection trip into the bid so a fail does not eat the job.
What do Eversource and United Illuminating require for temporary service?
They require you to follow their information and requirements, pass the municipal inspection, and have an account in order. Eversource covers most of the state. United Illuminating covers a southwest pocket. PURA's electric companies page is the clean public list when you are unsure who owns the street.[10][14]
I am not going to invent their current contribution rules, lead times, or temporary-service fees. Those sit in tariffs and in the utility's builder documents, and they change. Download the current information and requirements from the utility that actually serves the site. Then call the builder desk with the address.
Expect to furnish the temporary structure, the listed meter socket, the grounding, and a ready, safe work area. Expect them to refuse a set if the inspection is open or the mast is wrong. That is ordinary, not a vendetta.
If the lot needs primary, a pole, or a transformer, you left the simple temp-service world. Ask for a construction schedule in writing. Still no guarantees. Weather and clearance work move those dates.
Municipal electric towns (Norwich, Groton, Wallingford, and others) are not Eversource. Their spec books and their calendars are their own. Call that utility. Do not mail an Eversource form to a municipal desk and hope.
Are there extra costs if you use a diesel generator?
Yes. You add rental or ownership, fuel, delivery, spill control, noise limits, and possibly air paper. You do not subtract the electrical license or OSHA.
OSHA 1926.404 says, "The employer shall use either ground fault circuit interrupters as specified in paragraph (b)(1)(ii) of this section or an assured equipment grounding conductor program as specified in paragraph (b)(1)(iii) of this section to protect employees on construction sites."[6] That applies whether the source is a utility meter or a generator. Temporary wiring methods sit in 1926.405 as well.[7]
Air is the surprise cost. A unit you treat as a months-long prime power plant may not fit DEEP's emergency-engine box. Confirm with DEEP before you park a large diesel on a site for a season. I will not invent which engines need a permit or a registration this year. That is a DEEP question.
Fuel is a living number. I would put a diesel allowance in the contract with a true-up, not a heroic fixed gallons guess. Theft and after-hours fill-ups are real on open lots. Budget a lockable tank plan.
Noise ordinances are local. A 480V towable that is legal at 2 p.m. can be a police call at 9 p.m. next to houses. Ask the town.
I would not buy a generator to "get around" an Eversource delay unless I had priced fuel for the whole delay. In this state, that math goes bad fast.
What first-year paper hits a new temp power operator in Connecticut?
First year is paper, insurance, and waiting, more than cable. You need the correct DCP electrical license class before you offer the work.[5] You need whatever local contractor registration the towns you work in actually require. You need general liability. If you have employees, you need workers' compensation. You need a utility account process you understand. If you run generators, you need a DEEP answer in writing.
I will not invent DCP's current license fee, a quota, or a processing time. Open the electrical work practitioners page and read this week's instructions.[5] Same rule for exam fees.
Insurance minimums that a town or a GC wants are not always the same as whatever DCP asks to issue a license. Ask the building department and your carrier. Paying for a cheap policy that every school GC rejects is a waste.
Town-by-town registration is annoying and it is real. If you plan to work Hartford County and Fairfield County, budget time to file in more than one place.
If you want a paper checklist of cable, fuel, and 480V items in one place, TempPowerPath sells a $179 one-time Cable + Fuel + 480V Kit at /start. You do not need it to use this guide. This site is an independent publisher, not a law firm and not a service company.
Apprenticeship and journeyperson time is the real first-year constraint if you are not already licensed. Confirm the registered program with CT DOL.[12] Paying for ads before you can legally pull a permit is how people burn cash.
How do Connecticut electricity prices change the monthly burn?
They make long temp services expensive, and they make sloppy loads hurt. EIA's Connecticut state electricity profile is the public source I would cite in a bid memo when an owner asks why the temp bill is not "like Ohio."[8] Read the current average retail price on that profile. It has sat among the highest state figures for years. The exact cents move. The rank stays ugly.
A temp heat loop, a bank of 480V heaters, or a dewatering pump that runs all night will dominate the invoice. The pole rental is not the story after week six. The tariff is.
I would put a kWh allowance and a demand story in any proposal longer than a month. I would meter large temp loads if I can. Guessing is how you donate the job.
Labor does not get cheaper to offset that. BLS wage data for Connecticut electricians sits above a lot of the country on the OEWS table.[13] Confirm the current figures. High power prices plus high licensed labor is the Connecticut pattern. Plan for it.
If you are comparing markets before you hang a shingle, temp power cost in Illinois and temp power cost in Colorado are useful contrasts. Different commissions. Different kWh. Same need to read the local board.
What would I actually do if I were starting temp power in Connecticut?
I would get legal first. Confirm the E-2 or E-1 path on the DCP electrical work practitioners page, or hire a contractor who already holds it.[5] I would not "practice" on a friend's garage.
I would pick a service territory and learn that utility's book, not a generic YouTube pole.[14] Eversource and UI are not the same desk. A municipal utility is a third species.
I would walk into the building department of the first town I want to work in and ask how they want a temp service filed. Bring the license. Ask about contractor registration and insurance certificates. Write down the inspection phone number.
I would price utility temp service and a generator as two complete jobs, including fuel or kWh for the real calendar, not the hopeful one. I would open the EIA Connecticut profile before I promised cheap monthly power.[8]
I would skip buying a trailer-mounted 800A plant in year one unless I already had a contract that needed it. Rent the oddball. Own the boring 200A gear that passes inspection.
I would not bid public work until I understood prevailing wage. I would not promise dates. I would put "confirm with the building official and the utility" on my own estimate sheet so I do not start believing my marketing.
The $179 kit at /start is optional paper if you want a cable, fuel, and 480V checklist. Ignore it and this page still works. For other state stacks, see temp power cost in Alabama and temp power cost in Arkansas.
Frequently asked questions
Do you need a license for temp power in Connecticut?
Yes, if you offer or perform the electrical work. Chapter 393 requires the right DCP license unless a section 20-340 exemption applies. Temp poles, temp lighting, and generator distribution count as electrical work. Confirm the class (often E-1 or E-2) on DCP's electrical work practitioners page. Hiring an unlicensed helper to "just set the pole" is still offering licensed work.
How much does temp power cost in Connecticut?
There is no official statewide price. You stack DCP license paper, a local permit, gear or a rental generator, utility connection, inspection, and diesel or kWh. EIA ranks Connecticut retail electricity among the highest in the country, so long jobs get expensive. Confirm current board, town, and utility charges. A national package price is not a Connecticut bid.
How long does temp power take in Connecticut?
A simple pole can go in quickly after the permit, then inspection and meter set follow if the site is ready. Line extensions and transformer work take longer. License time is years through apprenticeship if you are starting from zero. Confirm schedules with the building official and the utility. Nobody can honestly guarantee a Friday turn-on.
Can a homeowner pull a temp power permit in Connecticut?
Maybe for work on their own residence, and only if the town and the licensing exemptions actually allow it. Section 20-340 is narrow. A house flip, a rental, or work you offer to someone else is not a homeowner loophole. Ask the local building official and read 20-340 before you buy a meter can. When in doubt, hire an E-1.
Is a generator a way around the electrical license?
No. The generator may be rental equipment. The conductors, overcurrent devices, grounding, and 480V tails are still electrical work under Chapter 393. OSHA still requires GFCI protection or an assured equipment grounding conductor program on construction sites. You also may owe DEEP a look at the engine. Confirm both boards.
What size temp service do most Connecticut job sites use?
Plenty of small builds run a 100A or 200A single-phase temp. Larger sites, tower cranes, and temp HVAC often need three-phase, sometimes 480V. Size from the actual load, not from habit. Oversizing wastes permit fees, gear, and utility work. Undersizing gets you a second pole. Have the E-1 do a load list before anyone orders a socket.
Who inspects temporary power before Eversource turns it on?
The municipal electrical inspector (or the official that town uses) inspects first. The utility then sets the meter if their spec is met and the account is in order. In UI territory or a municipal electric town, same idea, different utility desk. No inspection, no legitimate energize. Confirm the call-in process with that building department.
Do municipal electric towns follow the same temp power rules?
Licensing still sits with DCP under Chapter 393. The building permit still sits with the town under section 29-263 and the State Building Code. The connection rules and tariffs do not. Norwich, Groton, Wallingford, and other municipal utilities use their own service documents. Call that utility. Do not send an Eversource form and wait.
Does OSHA still apply if the town signed off?
Yes. A municipal sticker is not an OSHA waiver. 29 CFR 1926.404 still requires GFCI devices or an assured equipment grounding conductor program on construction sites. 1926.405 still covers temporary wiring methods. A later OSHA visit can fail a site that "had power." Keep the program and the testers on site, not in the shop.
What insurance do Connecticut electrical contractors usually carry for this work?
Plan on general liability, plus workers' compensation if you have employees. Towns and general contractors often ask for certificate limits above whatever you thought was enough. I will not invent a required dollar figure. Ask DCP what it wants for the license, then ask the towns and GCs you will actually bill. A cheap policy that every GC rejects is wasted premium.
Can I use a 480V spider box on a construction site in Connecticut?
Yes, if it is listed gear, installed by licensed people, overcurrent-protected, grounded, and used the way the listing and the adopted NEC allow. 480V does not get a pass because it is "only temp." Cam connectors need to be listed and mated correctly. Confirm the adopted NEC edition on the OSBI page. Unlisted yard specials fail inspection and fail OSHA.
Are temp power rental packages taxable in Connecticut?
Often yes on the tangible gear, but rental tax treatment has details I will not fake in a sentence. CGS section 12-408 is the sales and use tax statute. Read the current rate and the DRS sales tax page, or ask a Connecticut accountant, before you omit tax on a spider-box rental. Guessing tax the wrong way is a quiet way to lose the job's margin.
What happens if I leave temp power up after the building is done?
The adopted NEC treats construction temp power as lasting for the construction period. Other temporary uses have short clocks, including the familiar 90-day window for things like holiday lighting. The utility can pull a temp meter. The inspector can write it up. Convert to permanent service on purpose. Do not "forget" a temp pole behind the finished building.
Where do I confirm current DCP electrical license fees?
Use the Department of Consumer Protection electrical work practitioners page and the exam vendor that page names. I will not print a fee here because it goes stale and this is not the board. Same rule for processing time. If a blog quotes a number from three years ago, ignore it. Read the live DCP instructions the week you apply.
