TL;DR
Temp power in Colorado is licensed electrical work, not a handshake with the GC. A Colorado master or journeyman under C.R.S. 12-115 does the install. A city, county, or DORA permit and inspection come next. The utility or a job-site generator then energizes. There is no single state fee and no promised meter date. Confirm current charges with the AHJ and the serving utility.
What does temp power renewal mean in Colorado?
In Colorado, temp power renewal means keeping a temporary electrical installation legal for the rest of the job. That is a live permit (or a new one if the old one died), a still-valid electrician license, and a utility service or generator that the inspector and the serving utility still accept. It is not a separate statewide temp power license.
People mash three clocks together and then get mad at “the state.” The electrician license renews with the Department of Regulatory Agencies State Electrical Board. The electrical permit lives with whoever inspects that parcel, which may be a city, a county, or DORA itself. The utility’s temporary service file is a third clock, and it does not care that your license card is pretty.
Construction temp power in Colorado is almost always a short service (a pole or pedestal, a meter, a panel, GFCI protection, and cord and cable out to the trailer and tools) or a generator plant that never touches the utility. Renewal is the boring part after the first green tag. The job ran long. The temp meter agreement aged out. The permit expired because nobody called the next inspection. The GC wants the trailer powered through winter. That is the paper you are actually chasing.
I would not treat “renewal” as a special product. You either extend what the AHJ already opened, or you pull again and get another inspection. National writeups that talk about a Colorado temp power renewal certificate are inventing a form. Ask the inspector what they want in writing. Then do that.
Do you need a license for temp power in Colorado?
Yes, if you are installing or altering the temporary electrical system. Colorado treats that as electrical work. C.R.S. Title 12, Article 115 requires a license from the State Electrical Board before a person works as a master electrician, journeyman electrician, or residential wireman.[4] A registered electrical contractor has to stand behind the job.
Temporary does not mean unlicensed. A GC with a screwdriver and a Home Depot panel is still doing electrical work. The homeowner exemption in Article 115 is narrow and it is about a person’s own residence, not a commercial pad or a spec house you plan to sell. Confirm any owner-builder story with the same office that will inspect the pole. I would not bet a stop-work order on a forum post.
The board’s application path is public. Masters, journeymen, residential wiremen, and electrical contractors file with DORA DPO.[5] Reciprocity and exam details sit on those same application pages and they change. Confirm the current exam vendor, score, and experience affidavits with the board. Do not use a 2018 blog’s checklist as your filing packet.
On the job, OSHA still sits on top of the state license. Construction electrical work has to meet 29 CFR 1926 Subpart K. Temporary wiring can be a lighter class of method than permanent work, but the rest of the subpart still applies. OSHA’s text is blunt: “Temporary electrical power and lighting wiring methods may be of a class less than would be required for a permanent installation. Except as specifically modified in this paragraph, all other requirements of this subpart for permanent wiring shall apply to temporary wiring installations.”[1]
If you only need someone to fuel a rented towable and plug in cords that the electrical contractor already built, that is a different pile of rules (and still not a free pass on GFCI or grounding). The install itself is licensed work. That is the line I would draw, and it is the line inspectors draw when they see a brand-new temp pedestal with no permit card.
How much does temp power cost in Colorado?
There is no honest single price for temp power in Colorado. You are stacking a license and contractor registration (if you do this for a living), an electrical permit, utility temporary service charges, gear, and labor. Every one of those numbers is local or tariff-based. Anyone quoting “Colorado temp power costs $X” made the X up.
Permit fees live with the AHJ. Denver Community Planning and Development publishes its own permit types and fee tools for work inside the city.[9] Pikes Peak Regional Building Department does the same for the Colorado Springs area.[13] Unincorporated land with no local electrical program goes through DORA’s state electrical permit path.[5] I will not print a fee here because those schedules move, and a stale number is worse than no number. Pull the current fee page for that address.
Utility money is a second stack. Public Service Company of Colorado (Xcel) puts construction and service charges in its Colorado electric tariff and builder process, not in a blog graphic.[8][12] Co-ops and munis (United Power, CORE, Fort Collins Utilities, Colorado Springs Utilities, and the rest) each have their own extension rules. Temporary service can mean a flat connect charge, a contribution for the drop or transformer, after-hours fees, and a later conversion charge when you go permanent. Read the tariff page for that utility. Then call the construction desk with the load and the site sketch before you order a pole.
Labor is the third stack. The Bureau of Labor Statistics tracks electrician wages under SOC 47-2111, including Colorado statewide and metro tables.[10] Use the current OEWS release. Do not use a Facebook rate from 2021. On a simple single-phase temp pole the licensed contractor’s time plus gear often dwarfs the permit. On a 480Y/277 V construction service the gear and the utility design fee take over.
A generator path swaps the utility charges for rental or ownership, fuel, and maybe an air notice. That can be cheaper for a two-week remodel and ugly for a twelve-month pad. I would bid both paths with real quotes, not a national average. Paying a non-electrician “expediter” to walk a permit you still cannot legally install is a waste of money.
How long does temp power take in Colorado?
It takes as long as the slowest of three queues: the electrical contractor’s shop time, the AHJ permit and inspection, and the utility’s design and energize date. Nobody honest publishes a statewide clock, and I will not invent one. Same-week temp power happens on small jobs in cities that already know the contractor. Multi-week waits happen when Xcel or a co-op has to set a pole, extend primary, or wait on an easement.
Permit review is local. Denver and other home-rule shops run their own intake.[9] State-inspected counties run through DORA’s electrical permit process.[5] Some offices still want paper. Some want a portal. Incomplete load calcs and a missing contractor license number are how you lose a week without anyone “denying” you.
The utility clock is the one GCs forget. Xcel’s builder process is a sequence (apply, design, construct, meter), not a same-day truck.[8] Mountain co-ops can be faster on a simple overhead tap and slower if they are buried in storm work. Ask for a written construction timeline from the utility after they have the site plan. Verbal “should be Thursday” is not a schedule.
Inspection itself is often short once it is on the books. The delay is getting the slot and having the site ready. If the pole is in the mud, the grounding electrode is a joke, and the panel directory is blank, you will see the inspector once and then again. Renewal or a second temp on a stalled job can be quicker than the first file if the same contractor and the same utility account are still attached. Confirm that. Do not assume it.
I would never promise a customer a meter date. I would promise a complete packet this week and a utility request the same day the permit number exists. That is the only part you control.
Who inspects temp power in Colorado, DORA or the city?
It depends on the parcel. Colorado lets cities and counties run their own electrical inspection programs. Where they do, that local shop is your AHJ for the temp service. Where they do not, the State Electrical Board’s inspection program is the AHJ.[5][6] You do not get to pick the friendlier office.
Denver inspects Denver.[9] The Pikes Peak Regional Building Department inspects a defined list of El Paso County communities.[13] Lots of mountain and eastern counties still ride state inspectors. A job that straddles a city limit is how people pull the wrong permit and then wait. Check the address against the local building department first. If they say they do not do electrical, then you are in DORA’s stack.
The inspector releases the service. The utility will not set or energize a metered temp in most territories without that release. That handoff is the whole game. Your pretty panel does not matter until the AHJ and the utility agree it exists.
Code edition is the board’s call plus local amendments. Colorado adopts the National Electrical Code through the State Electrical Board. Confirm the edition in force on the DPO Electrical laws and rules pages before you order gear that only exists in the newest cycle.[6][7] A city can be stricter. It cannot shrug at the state license law.
If you work more than one county, keep a one-page map of who inspects where. That sounds dumb until you send a DORA permit into a city that will not honor it. I have no patience for that mistake. It is free to ask.
What do Colorado utilities require before they energize temp service?
A complete construction application, a site sketch that matches reality, the electrical permit or inspection release, and clear access to the point of delivery. Xcel documents that sequence for Colorado builders.[8] Other utilities rhyme. They do not copy each other’s forms.
Expect a load sheet. Temp construction services get treated like real services because they are. If you say 200 A and then hang a 400 A panel, you will redo the file. If you need 480 V three-phase for a tower crane or a temp heat plant, say that in the first sentence of the application. Surprise three-phase is how design queues reset.
Tariffs cover who pays for the pole, the transformer, the winter construction adders, and the later conversion to permanent.[12] Read those pages. Then get the construction coordinator’s name. A general customer-service number will not move a temp meter.
Right-of-way and easements kill more calendars than breakers do. A temp pole in the county road shoulder, or on a neighbor’s lot line, is not a clever hack. It is a relocate. I would stake the pole location with the utility locator and the inspector before the hole is dug.
Compare this to neighboring paper paths if you work across state lines. Temp power renewal in Arizona and temp power renewal in Idaho hit different boards and different utility rules. Colorado’s twist is the split between DORA and home-rule cities, plus a lot of co-op territory outside the Front Range.
Can you use a generator for temp power instead of a utility drop?
Yes. Plenty of Colorado sites never take a utility temp. A towable or a skid generator feeding a distribution panel is still temporary wiring under OSHA and still an electrical installation under the NEC.[1][7] You skipped the meter. You did not skip the license, the grounding, or the inspection the AHJ wants for the premises wiring.
OSHA’s construction grounding and GFCI rules still apply to the receptacles and cord sets on that plant.[2] “It is only a generator” is not an argument that works. Listed transfer equipment matters if the generator can backfeed anything that also sees utility power. A suicide cord over a panel is how people get killed and how contractors lose licenses.
Air rules are the part electrical guys forget. Colorado’s Air Pollution Control Division requires an Air Pollutant Emission Notice when an emission point meets the reporting levels in Regulation Number 3. Larger diesel plants can trip that. Portable and semi-portable engines are not automatically exempt just because they have wheels.[11] Confirm with CDPHE for the engine family, fuel, and hours you actually plan to run. I would rather send one email than explain an unpermitted engine to an inspector who also handles dust complaints.
Fuel storage, noise, and carbon monoxide sit next to the electrical paper. Do not park the set next to the job-trailer fresh-air intake. Carbon monoxide does not care that the run is temporary.
Cost-wise, a two-week interior remodel often wins on a rented single-phase set. A year-long multifamily pad usually loses. Run the fuel math with winter derate, not a brochure. If you are assembling a 480 V paper kit for cable, fuel planning, and gear lists, TempPowerPath sells a $179 one-time Cable + Fuel + 480V Kit as a publisher pack. It is not a Colorado permit and it is not a substitute for the board.
How long can temporary wiring stay in place in Colorado?
For construction, remodeling, maintenance, repair, or demolition, the NEC allows temporary power and lighting for the period of that work, not a cute 90-day cap.[7] The 90-day figure people repeat is the decorative-lighting rule in Article 590, not the job-site rule. Inspectors still get to decide when the “period of construction” ended.
OSHA does not hand you a calendar either. It tells you how the temporary methods have to be built while they exist.[1] When the building is done, the temp methods are done. Leaving holiday-grade cable as a permanent feeder is how you fail the last inspection and how you eat a rework.
Utilities add their own clock. A temporary service agreement is often written as temporary on purpose. Some shops want the temp meter pulled when the permanent meter sets. Some will convert in place. That is a tariff and construction-standards question, not a NEC question.[8][12] Ask in writing when you apply, not the week you want the C/O.
Permits expire. If the job sleeps for a winter and the permit dies, you are in renewal territory. That may be an extension if the AHJ still has the file, or a new permit if they do not. Confirm with the office that issued the original. I would put the expiration date on the inside of the temp panel door. Out of sight is how it gets missed.
If you are hunting a cleaner comparison of how other states treat that construction-period language, temp power renewal in California is a useful contrast because the AHJ patchwork is even louder there.
What usually fails a Colorado temp power inspection?
Bad grounding, missing GFCI protection, unlabeled or undersized conductors, and a site that does not match the permit. That list is boring because it is true. Inspectors are not hunting philosophy. They are hunting the same defects they saw yesterday.
OSHA is specific on receptacles. The employer has to use GFCI devices or a documented assured equipment grounding conductor program to protect people on construction sites. The standard points at 120-volt, single-phase, 15- and 20-ampere receptacle outlets on the construction site.[2] “We were going to add the GFCIs after the meter set” is not a plan.
Listed gear matters. OSHA’s general construction electrical rule expects equipment to be free of recognized hazards and used the way it was listed.[3] A gutter full of mystery breakers and a generator interlock made of a 2x4 will get red-tagged. So will a temp pole that moved six feet after the sketch was approved.
Other regular fails: no working clearance in front of the panel, a pedestal that is a leaning stick in thawing soil, open KO’s, service conductors that are not rain-tight, and a ground rod that is still in the truck. Mountain jobs add ice, grade, and a generator sitting in the only spot the inspector can stand.
I would walk the pole the afternoon before the inspection with the same checklist the AHJ publishes. If they do not publish one, use Article 590 plus the utility’s temp-service sketch and be done. Do not dress it up. Make it legal.
Do you renew the license, the permit, or the utility hookup?
You may have to renew all three, and they do not share a date. That is the whole mess. The electrician and the electrical contractor renew with DORA on the board’s cycle, including whatever continuing education the current rulebook requires. Confirm hours, due dates, and the eLicensing steps on the board’s own continuing education and applications pages.[5][6]
The electrical permit renews or dies with the AHJ. Some shops extend a temp or a construction permit if you ask before it expires. Some make you start over. Denver’s process is Denver’s process.[9] A state permit is a state permit. Call the number on the permit card, not a national call center.
The utility file is an account and a construction job, not a license. If the temp service was written with an end date, you either convert to permanent, ask for an extension in that utility’s system, or you get cut. Xcel’s builder and tariff pages are the starting point in its territory.[8][12] Co-ops will tell you their rule in one phone call if you already have an account number.
Do not let a lapsed electrician license sit under a live temp service. That is how a routine inspection becomes a complaint file. I would calendar the license first, the permit second, and the utility third. The license is the only one that also affects every other job you have in the state.
Working other states at the same time? Temp power renewal in Illinois and temp power renewal in Florida use different boards. Colorado will not babysit those dates for you.
What insurance do you need for temp power work in Colorado?
If you are the electrical contractor, you need whatever DORA and your customers already require to stay registered and bid, plus real general liability and workers’ compensation for the people on the tools. Temp power is still construction electrical work. A job-trailer fire or a backfeed into a utility line is not a hypothetical.
I will not invent a board minimum here. Insurance limits on contractor registration packets change, and some GCs will demand more than the state. Confirm the current certificate language with the State Electrical Board’s contractor materials and with the GC’s risk desk.[5][6] If a project sits on federal or CDOT work, expect the spec book to override your favorite policy.
Auto and inland marine get ignored until a rented generator walks off or a boom hits a service drop. Equipment floaters are cheaper than arguing with a rental house. Umbrella coverage is not a personality trait. It is how you stay in business after one bad 480 V event.
A property owner who only wants a weekend generator for a barn raiser is in a different insurance world than a contractor feeding a crane. Do not copy the contractor’s insurance list onto a homeowner job and call it done. Also do not copy a homeowner policy onto a paid electrical install. Those policies fight about “business pursuits.”
Waste of money: specialty “temp power insurance” branded products that are just a normal GL policy with a flyer. Get a broker who already writes Colorado electrical contractors. Ask them to read the utility indemnity language before you sign the construction application.
What would I actually do on a first Colorado temp power job?
I would hire or be a Colorado-licensed electrical contractor who already has a login with that utility’s construction desk. I would confirm who inspects the address, pull that permit, and submit the utility application the same day with a sketch that shows the pole, the trench or overhead route, and the load.[5][8][9] I would not order the pedestal until both offices have a number on the file.
I would build the temp to Article 590 and to OSHA Subpart K, with GFCI on the 15- and 20-ampere 120-volt receptacles, real grounding, and listed gear.[1][2][7] I would walk it the day before inspection. I would get the release to the utility myself, not through a GC text thread.
I would skip the cheap used panel with no label and the “we will ground it later” rod. I would also skip paying a middleman who cannot legally make up a service. If the site is generator-only, I would price fuel through the worst winter month and I would ask CDPHE whether that engine needs an APEN before it idles for a season.[11]
If you want another state’s paper path next, temp power renewal in Georgia is a clean next read. TempPowerPath is an independent publisher, not a law firm and not a service company. The Cable + Fuel + 480V Kit on /start is optional paperwork help. The State Electrical Board and your AHJ still own every fee and every stamp.
Frequently asked questions
Do you need a license for temp power in Colorado?
Yes for the install. Temporary service, temp wiring, and generator distribution are electrical work under C.R.S. Title 12, Article 115. A licensed master, journeyman, or residential wireman does the work under a registered electrical contractor. Confirm any owner-builder exception with the AHJ for that address. OSHA still applies on construction sites even when the state license is in order.
How much does temp power cost in Colorado?
It is a stack, not a sticker. Add the AHJ permit, utility temporary service and construction charges, gear, and licensed labor. Denver, PPRBD, and DORA each publish their own fee tools. Xcel and the co-ops put charges in tariffs. BLS tracks electrician wages under SOC 47-2111. Confirm every number for that address. Statewide averages on blogs are not real bids.
How long does temp power take in Colorado?
As long as the slowest of contractor shop time, AHJ review and inspection, and the utility energize date. Small city jobs with a known contractor can move in days. New three-phase or a line extension can take weeks. Nobody should promise a meter date. File a complete packet and get the utility job number early. Confirm current queues with that office.
Does Denver inspect its own temp power or does DORA?
Denver Community Planning and Development inspects electrical work inside Denver, including temporary services. DORA’s State Electrical Board inspects where no local electrical program exists. Do not send a state permit into a city that runs its own shop. Check the parcel first. The utility still needs that local release before most meter sets.
Can a homeowner pull a temp power permit in Colorado?
Sometimes, and only in the narrow owner-occupied lane the statute and the local AHJ both accept. A spec house, a rental, or a commercial pad is not that lane. Even when a homeowner permit is legal, the work still has to pass inspection and the utility still wants a proper service. Confirm with the building department for that address before you buy a panel.
Is a generator on a construction site required to have an air permit?
Not automatically. Colorado requires an Air Pollutant Emission Notice when an engine or other emission point meets Regulation Number 3 reporting levels. Larger diesels and long runtimes are the usual triggers. Wheels on the trailer do not settle it. Ask CDPHE with the engine family, fuel, and planned hours. Also keep OSHA and NEC rules on the electrical side of that set.
Does OSHA require GFCI on temporary receptacles?
On construction sites, OSHA requires GFCI protection or an assured equipment grounding conductor program. The written focus is 120-volt, single-phase, 15- and 20-ampere receptacle outlets used by employees. A temp pole that feeds tools without that protection is a fail waiting for a bad cord. Build it in before the inspection, not after someone gets bit.
What NEC article covers temporary installations?
Article 590 of NFPA 70, the National Electrical Code. Construction temp power may remain for the period of construction, remodeling, maintenance, repair, or demolition. The 90-day limit people quote is for holiday decorative lighting, not a job-site pole. Colorado adopts the NEC through the State Electrical Board. Confirm the edition in force before you buy gear.
Can I keep temp power after the building gets a certificate of occupancy?
Usually no, not as temporary methods. When construction ends, Article 590 installations are supposed to come down or become permanent wiring. The utility also wants the temporary service converted or removed. If you still need a trailer or temp heat, ask the AHJ and the utility for a written path. Do more than leave the pole up and hope.
Do Colorado electrical licenses transfer from other states?
Colorado offers paths that can recognize other states, but it is not a sticker swap. Exam, experience, and any reciprocity sit on the State Electrical Board application pages and they change. Confirm the current list and affidavits with DORA. You still need Colorado contractor registration to offer the work here. A wallet card from another state does not pull a Denver permit.
What size temp service do most job sites use?
Plenty of residential and light commercial sites run a 100 A or 200 A single-phase temp. Crane, temp heat, and larger multifamily sites jump to 400 A or to 480 V three-phase. Size it from a real load list, not a habit. Tell the utility the truth on the first application. Changing phase or amperage later resets design and can reset your calendar.
Who calls for the inspection, the GC or the electrician?
The electrical contractor of record should call it. The permit is in that license. A GC can request a date, but the inspector wants the electrician’s number and a site that is actually ready. Have the permit card, the utility sketch, and access to the pole. If the site fails, the same contractor should be the one to recertify the fix.
Are temp power poles allowed in the public right of way?
Only if the city, county, or CDOT and the utility all say so. A pole in a shoulder or sidewalk without that blessing gets moved, and you pay twice. Stake the location with the utility and the inspector before you dig. Private easements need the owner in writing. Hope is not a right-of-way grant.
What happens if temp power is installed without a permit?
The AHJ can red-tag it, the utility can refuse to energize or can pull the meter, and the contractor can face a board complaint under Article 115. You still do the work over, plus any stop-work delay. I would not try to legalize a live unpermitted service by calling it temporary. Pull the permit. Then call the inspection.
