TL;DR
Temp power in Colorado is licensed electrical work plus a company on paper. You need a State Electrical Board license (or a registered contractor with a master of record), a Secretary of State entity, tax accounts, and a local permit on every job. Utility temporary service sits in its own queue. Confirm each fee and wait with DORA, the AHJ, and the utility. Nobody can honestly promise a statewide turnaround.
Do you need a license for temp power in Colorado?
Yes. If you install, connect, or maintain temporary electrical systems in Colorado, that is electrician work. The State Electrical Board licenses the people who do it. The same board registers the contractor shop those people work under. A generator on a trailer does not replace that paper. [1]
Local building departments still permit the job. Utilities still control the meter or the temp pole. OSHA still applies on construction sites. Those layers stack. They do not cancel the state license.
Colorado law is blunt. C.R.S. 12-115-110 says a person shall not "engage in or work at the business, trade, or calling of a journeyman electrician, master electrician, or residential wireman in this state until the person has received a license from the board." [1] Temp power is not some special unlicensed class sitting beside that sentence.
There are narrow exceptions in the electricians article, including some owner-occupied work. Don't bet a commercial temp power shop on an exception you found in a forum. Read the current statute and board rules on DORA's Electrical laws page. Still guessing? Ask the board in writing and keep the reply.
Rent a generator and let the customer's licensed electrician make every connection, and you may be in equipment rental, not electrical contracting. The second you land lugs, build a spider box, or energize a temp panel, you are in the trade. I wouldn't play word games with that line. Inspectors don't.
Journeyman cards do not automatically let you advertise as a contractor. Contractor registration is a separate board filing that names a master electrician of record. Confirm the current packet on DORA's Electrical Applications page. Don't copy a fee from a blog. Fees move. [2]
Out-of-state licenses do not automatically transfer. Colorado has its own exams and experience rules. Reciprocity, if any exists for your credential, is a board policy, not a handshake at the border.
Get the license question answered before you buy a second service truck. Paper first. Iron second. A longer walk through the credential types is in temp power license in Colorado.
What paper comes first, the company or the electrician card?
The electrician card comes first if you are the one doing the work. The company comes first if you already employ (or partner with) a Colorado master who will be the master of record. An LLC with no licensed electrician cannot pull electrical permits. A licensed master with no entity can often still work, but you'll want a company before you hire anyone or bid commercial jobs.
I form the entity once I can name the master. Not before. Filing an LLC is cheap. Holding a hollow company while you wait years for hours is just another annual report.
Colorado Secretary of State handles entities. Articles of organization for an LLC cost $50 on the published fee schedule. [5] Confirm that figure on the current fee list before you pay. Periodic reports are a separate annual filing on the same schedule. An EIN is free if you apply on IRS.gov. Do not pay a reseller for an EIN. [6]
Skip the four-figure "formation bundle." The SOS site is enough. Name the company something you can live with on a permit sticker.
Then get a Colorado sales tax account if you'll sell taxable goods or taxable services. Set unemployment and withholding if you'll have employees. Those are different counters at DOR and CDLE, not one magic business license. [8][9][11][15]
| Paper | Who issues it | What I'd do |
|---|---|---|
| Entity (LLC or corp) | Colorado Secretary of State | File yourself. LLC articles are $50 on the published schedule. |
| EIN | IRS | File free on IRS.gov. |
| Electrician license | DORA State Electrical Board | Confirm applications, hours, and fees on the board site. |
| Contractor registration | DORA State Electrical Board | Name a Colorado master of record. |
| Sales tax license | Colorado Department of Revenue | Needed if you sell taxable items or taxable services. |
| Local electrical permit | City or county AHJ | Every job. No statewide substitute. |
That table is the real order. National "just register your business" checklists skip the board, then act surprised at the first inspection.
What does the Colorado State Electrical Board actually issue?
The board licenses people and registers contractors. Those are different papers. People hold master, journeyman, residential wireman, and apprentice credentials. Shops hold electrical contractor registration tied to a master. Mixing those up is how people bid work they can't permit. [1][2]
Confirm titles and experience hours on the current applications page. I won't invent hour counts here. Boards change matrices. The applications packet is the source, not a national forum post from 2019. [2]
Exams are separate from the application. Colorado uses a testing vendor. Schedule, retake rules, and candidate handbooks live with that vendor and with DORA. Confirm both on the day you think you're ready.
Residential wireman is not a free pass to run 480V construction temp power on a commercial site. Match the credential to the occupancy and the voltage. Commercial or industrial temp power means a journeyman or master under a registered contractor.
Apprentices work under supervision rules. They do not "get the temp pole up" unsupervised because it's temporary. Temporary is not a training exemption.
Coming from how to start temp power in Arizona or how to start temp power in California? Don't assume the same license names mean the same scope. They don't. Colorado tests you on Colorado rules.
Keep one master of record who actually works in the shop. Paper masters who never see a job still leave you on the hook when an inspection fails.
How much does temp power cost in Colorado?
There is no honest statewide price for a temp power job. Anyone quoting a single Colorado number is selling a myth. Costs split into business paper, labor, equipment, utility charges, and permits. Only a few of those are published.
Business paper is the part you can look up. Colorado Secretary of State lists $50 to file LLC articles of organization. [5] An EIN is $0 on IRS.gov. [6] Colorado's state sales tax rate is 2.9 percent per the Colorado Department of Revenue. [8] Local districts stack on top of that 2.9 percent. Electrical board exam and registration fees change. Confirm those on DORA. Insurance is a quote, not a statute.
Job cost is messier. Utility temporary service charges live in each utility's PUC-filed tariff, not on a blog. Xcel Energy and other Colorado utilities publish builder and construction processes. Read the current tariff sheet before you bid a temp pole. [13] AHJ permit fees are local. Denver is not Grand Junction, and a ski-county inspection trip is not a Denver counter visit.
Equipment is where new operators light money on fire. A used spider box and decent cordage can be rational. A brand-new 480V lineup before your first permitted job is usually a waste. Rent until the work is real.
Generator diesel, cable, and GFCI protection add up per day. OSHA still wants GFCI protection or an assured equipment grounding conductor program on construction sites. [4] That gear is a cost of doing the work, not an upgrade package.
Budget paper and insurance first, then a tight equipment list, then refuse to guess utility charges. Call the utility. Call the AHJ. Put those numbers on the bid.
Nobody has good public data on average Colorado temp-power invoices. The closest honest method is your last three similar jobs, or a utility tariff plus permit fee plus labor hours. If a salesperson hands you a "typical Colorado temp power package" price, ask which tariff sheet it came from. They usually can't say.
How long does temp power take in Colorado?
It depends which clock you mean. Forming an LLC with the Secretary of State is often fast when you file online. An EIN is immediate online if the IRS site is working. [5][6] I still won't promise a day count. Queues change, and same-day is not a right.
The electrician license is not a weekend project if you don't already have the hours. Experience, exam seats, and board review sit on a different calendar. Confirm current processing notes with DORA. Don't use a number you saw in a Facebook group. [2]
Job-level temp power is local. A complete permit, an inspection, and a utility connection can be days in a well-staffed city or much longer if the utility has a construction backlog or the county inspects twice a week. Denver's permit shop is not your mountain county's. [10][13]
I would never sell a customer a guaranteed energize date until the AHJ and the utility have the request in their system. Weather, missing GFCI devices, and a wrong one-line blow up calendars. Your truck being ready does not move a utility construction desk.
Plan the long pole first. If the site needs utility temp service, that request often outlasts your panel build. If the site is generator-only, the AHJ still has to inspect before you load people onto the system.
Need a comparison for another state's paper path? How to start temp power in Tennessee is a different board and a different clock. It will not speed up a Colorado inspection.
What permits and inspections hit each job?
Every temp power installation needs the local authority having jurisdiction, unless a true statutory exception applies. State electrician licensing does not replace the permit. Denver Community Planning and Development runs its own permit path. Other cities and counties run theirs. Unincorporated work goes to the county. [10]
Typical stack: electrical permit for the temp service or temp distribution, inspection before energizing, and a utility release if the utility is supplying the service. Some sites also need a separate building or grading permit before the temp pole even goes in. Ask the AHJ. Don't assume the GC already did it.
Inspectors look at grounding, bonding, GFCI, strain relief, wet-location covers, working space, and whether the gear matches the permit. Temporary is not code-optional. OSHA 29 CFR 1926.405 says, "Temporary wiring shall be removed immediately upon completion of construction or the purpose for which the wiring was installed." [3] Leave a "temp" panel up as a permanent hack and you have a problem.
I pull the permit in the contractor's name, with the master of record straight. I do not let a GC "just put it in their name" if my shop is making the connections. When something fails, the name on the permit is the name that gets the call.
Reinspection fees are real in many Colorado cities. Budget one extra trip. It's cheaper than arguing on the dirt.
Listed gear matters here too. OSHA 29 CFR 1926.403 requires listed, labeled, or certified equipment to be installed and used in accordance with its listing. [14] Homemade distribution with drywall screws is not a business model.
How do Colorado utilities handle temporary service?
Utilities run their own construction desks. Xcel Energy publishes builder-facing processes for electric service work in Colorado. Other providers (municipal utilities, co-ops, and investor-owned utilities in their territories) have their own rules. [13] You cannot skip them because you already have a DORA card.
Expect an application, a site plan, a desired date, and sometimes a contribution or a tariffed temp-service charge. Those dollars live in the tariff. Confirm the current sheet. I won't invent a connection fee, and you shouldn't bid one from memory.
Lead time is the part that kills schedules. Order temp service when the GC still thinks it's early. Late orders sit behind real work. A complete packet beats a friendly phone call with no drawings.
Generator-only site? You still may need the AHJ. You may also need air-quality paper if the engine is large enough for CDPHE's Air Pollutant Emission Notice rules. Confirm thresholds with CDPHE. Don't guess horsepower cutoffs from memory. [12]
Who calls the utility? I want my shop on the ticket if my shop is landing the service. GCs lose emails. You still own the failed inspection.
Meter spots, clearances, and underground vs overhead change the design. Walk the site before you order gear. A temp pole that does not meet the utility's book of standards will not get hot, no matter how pretty your spider boxes look.
What insurance and tax accounts do you actually need?
If you have one or more employees in Colorado, you generally need workers' compensation insurance. That sits with the CDLE Division of Workers' Compensation. It is not a nice-to-have. [7] A single-member LLC with no employees is a different fact pattern. Confirm your facts with CDLE or a Colorado insurance producer. I am not your broker.
Unemployment insurance accounts sit at CDLE too if you have employees. [11] Wage withholding sits at the Department of Revenue. [15] Hire one helper and those accounts stop being theoretical.
General liability is what GCs and site owners will demand even if you did not see a single required limit on the board page you read today. Confirm any board-required insurance on the contractor application. If the application is silent, the market still is not. I would not bid a construction site with a thin policy and a smile. Get a real quote.
Sales tax is the quiet one. Colorado's state sales tax rate is 2.9 percent per the Colorado Department of Revenue. [8] Locals add more. If you sell rental, resale gear, or taxable services, register. [9] Fuel and equipment treatment can be fact-specific. Ask DOR or a Colorado CPA. Wrong tax on generator fuel is a boring way to get a bill.
Keep certificates of insurance in the same folder as the contractor registration. Jobsite offices ask on day one. Digging through email on a frozen morning is a waste.
What equipment and 480V issues show up on real sites?
480V temp power is common on commercial and industrial sites. It's also where unlicensed operators get hurt and get stopped. You need listed gear, correct overcurrent protection, and people whose license matches the voltage and occupancy. Residential wireman scope is not your 480V plan.
OSHA 29 CFR 1926.404 requires GFCI protection or an assured equipment grounding conductor program to protect employees on construction sites. [4] That is federal. It applies on Colorado construction sites with employees. "We'll add GFCI later" is not a program.
Cable ampacity, voltage drop, and wet-location connectors are the boring things that fail inspection. Buy cordage that matches the load. Don't daisy-chain household cords to a 3-phase panel. Color-code, strain-relief, and cover every live part.
Want a simple cable, fuel, and 480V paper checklist? TempPowerPath sells a $179 one-time Cable + Fuel + 480V Kit. You do not need it to follow this guide. The board, the AHJ, and OSHA still win.
Skip the fancy distribution trailer until you have repeat work. Rent the oddball 480V transformer. Own the stuff you use every week. A trailer payment on a quiet winter is a bad hobby.
Compare that to temp power license in Texas only for curiosity. Texas paper will not pull a Colorado permit, and Texas 480V habits will not satisfy a Denver inspector by themselves.
What do first-year operations look like without the myth?
First year is permits, callbacks, and waiting on utilities. It is not a fleet of wrapped trucks. You will spend more time on inspection corrections than on ads.
Hire slow. Employees trigger workers' comp, unemployment, and withholding. [7][11][15] Subcontracting to another licensed shop can be cleaner than pretending you have a crew you cannot cover.
Keep a job folder: permit, inspection, one-line, cable list, GFCI test log, utility ticket. Inspectors and GCs ask. You should already have it. Phone photos of unlabeled panels are not a folder.
I would not sign a year-long generator farm lease in month one. I would not paint a service area across the whole Front Range. Pick a utility territory and learn that desk. Temp power work clusters around construction, and construction clusters around who can actually get service energized.
Colorado winters wreck outdoor gear. Budget covers, extra cordage, and more time for inspections when roads are bad. That's operations, not a slogan.
Cash gets tight when a utility date slips and your rental meter keeps ticking. Bid that risk or refuse the job. Eating diesel for two extra weeks is how first-year shops vanish.
Is generator temp power different from utility temp power?
Yes. Utility temp power is a tariffed service plus your permitted installation. Generator temp power is equipment plus fuel plus (usually) the same electrical permit if you are installing distribution. The AHJ still cares about the panel, the grounding, and the flexible cords.
Generators add fuel handling, noise, and sometimes air permits. CDPHE APEN rules can apply to engines. Confirm whether your engine size and hours trip a notice. Don't copy a horsepower cutoff from another state. [12]
OSHA still applies. So does the board. "It's just a rental" dies the moment your people make up the feeders.
Use utility temp service when the site will last and the utility can actually perform. Use generators for short, remote, or pre-utility windows. Mixing both without a clear one-line is how you backfeed a lineworker. Don't.
Fuel logistics are operations, not an afterthought. Who fills, who spills, who holds extra filters, who has the key to the disconnect. Write it down. Night shifts will not remember your verbal plan.
If the GC wants both a temp pole and a generator "just in case," make the interlock and the permit scope explicit. Parallel sources without listed transfer equipment is not clever. It is a cut.
What would I skip, and what do I confirm with the board?
Skip license consultants who fill out DORA forms you can read yourself. Skip buying 480V switchgear on credit before your contractor registration is real. Skip promising a two-day energize in a county that inspects on Thursdays.
Confirm with the State Electrical Board: current license types, experience hours, contractor registration, exams, and every fee. [1][2] Confirm with the AHJ: permit, inspection, temp vs permanent. Confirm with the utility: temp service charges and lead time. [13] Confirm with CDLE and DOR: workers' comp, UI, withholding, sales tax. [7][8][9][11][15]
I would rather lose a bid than invent a date. Boards and utilities do not care that your quote already went out.
TempPowerPath is an independent publisher, not a law firm and not a service company. Want the optional kit? It's at /start. None of that replaces a board confirmation, and this article still works if you never click it.
If you like reading other state paper paths, how to start temp power in Alabama and how to start temp power in Alaska show how fast the rules stop matching once you leave Colorado.
Frequently asked questions
Do you need a license for temp power in Colorado?
Yes for electrical installation, connection, or maintenance of temp systems. Colorado requires a State Electrical Board license to work as a master, journeyman, or residential wireman, and contractor registration for the shop. A generator rental with no connections may be different. Confirm scope with DORA before you bid.
How much does temp power cost in Colorado?
There is no honest statewide job price. LLC articles of organization are $50 on the Colorado Secretary of State fee schedule. An EIN is free on IRS.gov. State sales tax is 2.9 percent, plus local. Board fees, permits, utility tariff charges, and insurance are separate. Confirm each with the issuer before you bid.
How long does temp power take in Colorado?
Entity filing and an online EIN can be fast. An electrician license is not, if you still need hours and an exam. Job-level temp power depends on the local permit shop and the utility construction queue. Nobody can honestly promise a statewide energize date. Confirm current waits with DORA, the AHJ, and the utility.
Can a general contractor pull temp power without an electrician?
Not if the work is electrical installation under Colorado's electricians article. A GC may hold the building permit, but connections, temp panels, and service make-up need licensed electrical people and, for a shop, contractor registration. Ask the AHJ who may be the electrical permit holder on that site.
Do I need a master electrician or is a journeyman enough?
A journeyman can do licensed work in the field under the rules that apply to that credential. Advertising and permitting as an electrical contractor is a different paper path that names a master of record. Confirm current contractor registration rules on DORA's Electrical Applications page before you print a shop name on a van.
Does a generator rental company need electrical contractor registration?
If the company only drops a machine and a licensed electrician makes every connection, it may stay in rental. If staff land feeders, build distribution, or energize panels, that is electrical contracting. I would not guess. Ask DORA with a written scope and keep the answer with your insurance file.
Is a Denver permit different from a mountain county permit?
Yes. Denver Community Planning and Development runs its own permit and inspection path. Other cities and counties set their own fees, portals, and inspection days. State licensing does not replace any of that. Always ask the AHJ that owns the dirt, not the last city you worked in.
Do I need workers' comp as a single-member LLC?
If you have one or more employees in Colorado, you generally need workers' compensation insurance through the CDLE Division of Workers' Compensation framework. A true no-employee single-member LLC is a different fact pattern. Confirm your facts with CDLE or a Colorado producer before you assume you are exempt.
Does Colorado charge sales tax on generator fuel and rental?
Colorado's state sales tax rate is 2.9 percent, and local districts add more. Whether a specific rental, resale, or fuel charge is taxable is fact-specific. Register with DOR if you sell taxable goods or services, then ask DOR or a Colorado CPA about fuel and rental treatment instead of copying another shop's invoice.
Can I use an electrician license from another state?
Not automatically. Colorado issues its own credentials and runs its own exams and experience rules. Any reciprocity or endorsement path is a board policy you must confirm with DORA. Do not bid Colorado temp power on an out-of-state card and hope the inspector likes your story.
What about 480V temp power specifically?
Treat 480V as commercial or industrial work with listed gear, correct overcurrent protection, and people whose license matches the occupancy and voltage. Residential wireman scope is the wrong plan. OSHA still wants GFCI protection or an assured equipment grounding conductor program on construction sites with employees.
Do I need a PUC certificate to start temp power?
Typical construction temp power contracting is not an electric utility. You still need electrical licensing, contractor registration, local permits, and utility coordination if the IOU or co-op supplies the service. If you plan to sell electricity as a public utility, that is a different Colorado PUC question. Most shops never go there.
Are apprentices allowed to build temp power unsupervised?
No. Temporary does not mean unsupervised. Apprentices work under the board's supervision rules. Temp poles, spider boxes, and 480V feeders are still electrical work. Use apprentices as apprentices. Do not send an unlicensed helper to "just make it hot" before the inspector arrives.
Where do I confirm fees and processing times?
Confirm electrician and contractor fees with DORA's Electrical Applications and laws pages. Confirm entity fees with the Colorado Secretary of State fee schedule. Confirm sales tax with the Department of Revenue. Confirm workers' comp and UI with CDLE. Confirm job permits with the local AHJ and temp service charges with the utility tariff.
