TL;DR
Texas temp power work falls under TDLR electrical licensing (Texas Occupations Code Chapter 1305). You need a licensed electrician of record for installations that touch a structure's wiring. Licenses renew every two years, with fees running roughly $40 to $140 by class. Local permit processing runs from same-day to several weeks. Confirm current figures with TDLR and your local AHJ.
Do you need a license for temp power in Texas?
Yes, though the details matter. Texas regulates electrical work through the Texas Department of Licensing and Regulation (TDLR), which administers the state Electrician Licensing Law under Texas Occupations Code Chapter 1305 [1]. Anyone who installs, repairs, or maintains electrical wiring or equipment for pay must hold an appropriate TDLR electrical license, or work under the direct supervision of someone who does.
The trigger for temp power is simple. Are you making an electrical connection to a structure's wiring, a utility service point, or a generator transfer switch? Running a cord from a rented generator to a panel does not exempt you. If the work touches the building's electrical system, a licensed Master Electrician or a Journeyman working under one is required.
A few exemptions exist. Homeowners doing work on their own single-family residence are exempt under Tex. Occ. Code § 1305.003 [1]. Agricultural operations have a separate carve-out. But a contractor, event company, or construction firm setting up temporary power for a commercial project, a job trailer, or a public event has no exemption. You need the license.
Four license classes matter for temp power: Apprentice Electrician, Journeyman Electrician, Master Electrician, and Electrical Contractor. The Electrical Contractor license is the entity-level credential required to pull permits and sign contracts. The Master Electrician is the qualifying individual behind that contractor license. Both must be current at renewal time.
How does Texas TDLR electrical licensing work?
TDLR is the single state authority. No county-level electrical license in Texas substitutes for the TDLR credential, though some cities (Houston historically, and a handful of others) ran their own licensing programs before state preemption. The 2017 legislative session largely consolidated authority under TDLR, so one TDLR license covers the whole state [1].
Licenses run in two-year terms. The Journeyman exam requires 8,000 hours of verified apprenticeship work. The Master exam requires an active Journeyman license and at least two more years of experience. Continuing education is required at renewal: 8 hours per cycle for Journeymen and Masters. The education requirement is not optional, and TDLR audits for it.
The Electrical Contractor license (the entity license) requires a sponsoring Master Electrician, proof of general liability insurance, and workers' compensation coverage or an approved alternative. That insurance piece is something many first-year operators underestimate. You cannot renew the contractor license if the insurance lapses, and TDLR verifies coverage at renewal.
On construction sites, the general contractor often assumes the licensed electrician is someone else's problem. It is not. The subcontractor doing electrical hookups owns the license responsibility, but the GC carries permit liability if unlicensed work turns up at inspection.
How much does temp power cost in Texas?
Three cost buckets apply: licensing fees, permit fees, and the physical equipment plus labor.
TDLR License and Renewal Fees
TDLR publishes its fee schedule, though fees are subject to legislative and board adjustment. As of the most recent published schedule, Electrical Contractor license renewal is $140 for a two-year term; Journeyman renewal is about $40; Master Electrician renewal is about $70. Confirm these with TDLR directly before budgeting, because the Legislature has authorized fee changes in recent sessions.
Permit Fees (Local AHJ)
Permit costs are set by each Authority Having Jurisdiction, not by the state. A small temporary service permit in a rural county might run $50 to $75. A major city project permit with plan review can top $500. Austin, Dallas, Houston, and San Antonio each post their own fee schedules. There is no statewide cap.
Equipment and Labor
Generator rental for a construction site in Texas typically runs $150 to $400 per day for a 20 to 50 kW unit, or $800 to $2,500 per month, depending on fuel type and capacity. Transfer switch installation by a licensed electrician adds $500 to $2,000 depending on panel size and job complexity. If you assemble your own cable, fuel management, and 480V three-phase connection kit from scratch, expect $800 to $2,000 in parts alone before labor. For a sense of underlying equipment cost drivers, the U.S. Energy Information Administration publishes capital cost data on generation units [4].
TempPowerPath's Cable + Fuel + 480V Kit ($179 one-time) is worth knowing about at the planning stage because it bundles the documentation and specification checklist for those three components, which cuts the back-and-forth with inspectors on what cable gauge and transfer equipment meets NEC standards for your load [see /start]. The kit is a reference and planning tool, not a substitute for licensed installation.
The table below shows representative ranges across the main fee categories:
| Cost Category | Low Estimate | High Estimate | Notes |
|---|---|---|---|
| TDLR Electrical Contractor Renewal | ~$140 | ~$140 | 2-year term; confirm with TDLR [2] |
| TDLR Journeyman Renewal | ~$40 | ~$40 | 2-year term; confirm with TDLR [2] |
| TDLR Master Electrician Renewal | ~$70 | ~$70 | 2-year term; confirm with TDLR [2] |
| Local Temp Power Permit | $50 | $500+ | Varies by city/county AHJ |
| Generator Rental (per month, 20-50 kW) | $800 | $2,500 | Market rate, fuel extra |
| Transfer Switch Installation (labor) | $500 | $2,000 | Licensed electrician required |
How long does temp power take in Texas?
Two timelines matter: the TDLR renewal and the local permit. They run in parallel if you plan it right, or they stack up on you if you do not.
TDLR Renewal
TDLR processes online renewals through its MyLicense Office portal [2]. If your continuing education is complete, your insurance is current, and there are no enforcement holds, online renewal is typically approved within a few business days. TDLR sends a renewal notice roughly 90 days before expiration. Renew late (after the expiration date but within the allowed grace window) and a late fee applies. Let the license lapse entirely and you may need to reapply instead of renew, which is a much longer and more expensive path.
Local Permit Timelines
Here is where Texas gets complicated. Because permit authority is local, processing runs from same-day over-the-counter issuance in small counties to 3 to 8 weeks for review in high-volume cities like Austin or Dallas. Austin's Development Services Department reports permit review timelines that stretch to several weeks during peak construction periods [5]. Houston's portal shows similar variance.
For temporary power tied to a construction project, many jurisdictions issue the temp power permit as part of the full building permit package. If the main permit stalls, so does your temp power connection. Request a standalone temporary service permit early, before the main permit issues, if your jurisdiction allows it.
The fastest path in most Texas jurisdictions: file electronically, include a complete load calculation, attach the licensed contractor's information correctly the first time, and call the AHJ to confirm what they need before you submit. An incomplete application can sit for weeks without a single note back.
What is the TDLR renewal process step by step?
The renewal process is short if you start before the deadline. Here is how it works.
1. Log into MyLicense Office at the TDLR website [2]. Your renewal notice includes a link and your license number. 2. Verify that your 8 hours of continuing education for the cycle are recorded. TDLR accepts CE from approved providers listed in the MyLicense system. If you took a course but the provider never uploaded the completion record, contact the provider first, then TDLR if needed. 3. For Electrical Contractor licenses, confirm your general liability and workers' compensation certificates are on file and current. TDLR requires a certificate naming TDLR as a certificate holder. 4. Pay the renewal fee online. Major credit cards work. 5. Print or save your renewed license confirmation. The physical card comes by mail, but the digital confirmation covers most inspections.
If your license expired within the last year, TDLR typically allows late renewal with a late fee rather than forcing full reapplication, but that window is not guaranteed. Check your specific license class rules in the TDLR Electrician Rules under 16 Texas Administrative Code Chapter 73 [6].
One thing that catches people: the Master Electrician sponsoring a contractor entity must renew their individual license separately from the entity license. Two separate renewals, two separate fees. Miss one and the other goes invalid for pulling permits.
What insurance does a Texas temp power contractor need?
The Electrical Contractor license requires proof of general liability insurance and either workers' compensation or an approved alternative. TDLR's administrative rules set minimum coverage amounts and require the certificate to name TDLR as a certificate holder. The general liability minimum has been $300,000 per occurrence in recent rule versions, but verify the current figure in 16 TAC Chapter 73 [6] because these get amended.
Workers' comp in Texas is unusual nationally. Texas does not require private employers to carry workers' compensation insurance under the Texas Workers' Compensation Act (Texas Labor Code Chapter 406) [7]. TDLR requires it anyway for Electrical Contractor licensees, or proof of a qualifying alternative. This trips up contractors who know the general Texas opt-out rule and assume it covers their TDLR credential. It does not.
For temp power on public projects or utility-adjacent work, project owners often add certificate holders and higher limits. State agency projects frequently specify $1,000,000 per occurrence. Read the project's insurance requirements before you sign the contract, not after.
How does utility coordination work for temporary power in Texas?
Most of Texas runs a deregulated electricity market (the ERCOT territory), which means you choose a retail electric provider, but the physical wiring and metering belong to a Transmission and Distribution Utility (TDU) such as Oncor, CenterPoint Energy, or AEP Texas [8]. That split shapes temp power.
When you need a temporary utility service (a temporary meter and service entrance for a construction site), the sequence is: the licensed electrician installs the temporary service equipment to utility specs, the AHJ inspects and issues a release, then the TDU installs the meter. You do not call the TDU until after inspection approval. Calling first wastes time.
CenterPoint Energy serves the Houston area and files its Electric Distribution Tariff, including temporary service requirements, with the Public Utility Commission [9]. Oncor's tariff covers the Dallas-Fort Worth region. Both are public documents you can cite in a scope of work or a dispute.
For off-grid temp power (generator only, no utility connection), there is no TDU coordination. The licensed electrician installs the transfer equipment, the AHJ inspects it, and you fuel up. That is the faster route for short-duration construction jobs in areas where utility hook-up fees and timelines make the math work against a utility temp service.
What are the NEC requirements for temporary power installations in Texas?
Texas adopts the National Electrical Code (NEC), but the adopted edition varies by jurisdiction. Some Texas cities use NEC 2017, others NEC 2020, and a few have moved to NEC 2023. Before you design a temp power installation, confirm which edition your AHJ has adopted [10].
For temporary wiring, NEC Article 590 is the governing section. It defines allowed wiring methods, the duration limits for temporary installations (90 days for holiday decorative lighting; construction power has no fixed maximum but must come down when construction is complete), and the ground fault and arc fault protection rules [10].
Key Article 590 requirements for construction temp power: GFCI protection is required for all 15A and 20A, 125V receptacles used by personnel. Feeders can be cable assemblies or cord sets rated for hard usage. Temporary lighting must be protected from physical damage. These are not suggestions. An inspector who finds unprotected temporary wiring on a Texas job site will red-tag the project.
The NEC is published by the National Fire Protection Association (NFPA) as NFPA 70 [10]. You can read it for free online through NFPA's LiNK viewer after creating a free account.
How does Texas temp power compare to neighboring states?
Knowing how Texas stacks up helps if you work across state lines or move a project from one state to another.
Louisiana licenses electrical contractors through the Louisiana State Licensing Board for Contractors, with separate journeyman and master credentials similar to Texas. See temp power renewal in florida for another Gulf-state comparison. New Mexico's Construction Industries Division licenses electricians statewide, close to TDLR's structure. Oklahoma's Construction Industries Board licenses electrical contractors with its own exam and renewal cycle.
Arkansas and Alabama both run statewide electrical licensing, though their CE requirements and fee structures differ from Texas. Compare those states in detail at temp power renewal in arkansas and temp power renewal in alabama.
The real difference for temp power is Texas's deregulated electricity market. In most neighboring states, the utility is vertically integrated, so one call handles both distribution and retail. In ERCOT Texas, you deal with a TDU for distribution and a separate REP for supply. That two-entity structure adds coordination time to any utility-connected temp service.
Colorado and Arizona sometimes come up as examples of more streamlined temp power permit processes. See temp power renewal in colorado and temp power renewal in arizona for those specifics.
What are common reasons temp power renewals get denied or delayed in Texas?
Most renewal problems fall into a small set of categories.
Continuing education not uploaded. CE providers have a window to upload completion records to TDLR's system. Take the course right before your deadline with a slow provider and your renewal shows CE incomplete. The fix is simple: take CE at least 60 days before your renewal date.
Insurance certificate expired or TDLR not named. The certificate must name TDLR as the certificate holder at the correct TDLR mailing address. A generic additional-insured endorsement is not the same thing. Your broker needs to issue it correctly the first time.
Enforcement hold. If TDLR has an open complaint or enforcement action against your license, renewals can sit pending resolution. You will not always get a separate notice about the hold. Log into MyLicense Office and check your status before you assume renewal is clean.
Sponsoring Master Electrician left the company. If a departed Master sponsored your contractor license, you need a new sponsoring Master before the next renewal. TDLR does not grant an automatic grace period. The contractor license stays unrenewable until a qualifying Master is listed.
Wrong entity type. Sole proprietors, partnerships, corporations, and LLCs each carry slightly different documentation requirements in the TDLR system. A change in business structure during the license term means updating the record, which is more work than a straight renewal.
For first-year operators, the TempPowerPath /start resource covers the setup documentation checklist, which overlaps a lot with what you need clean for renewal cycles.
What local Texas jurisdictions have their own temp power requirements?
TDLR preempts the field for electrical licensing, but local jurisdictions still control permits, inspections, and which NEC edition applies. A few worth knowing:
Austin. Austin Development Services requires a separate temporary electrical permit for construction power. The fee schedule updates annually and posts on the Austin Development Services site [5]. Austin has adopted NEC 2020 in recent years.
Houston. Houston runs its own permitting portal for electrical permits. Because Houston sits in an unregulated utility territory (CenterPoint), the TDU coordination step applies to any utility-connected temp service.
Dallas. Dallas issues temp power permits through its Development Services Department. Load calculations and site plans are typically required for anything above a basic construction service. Dallas ran on NEC 2017 for several years after that edition's release.
San Antonio. CPS Energy serves San Antonio as a municipally-owned utility, not a TDU/REP split. CPS Energy handles both distribution and supply, which simplifies coordination for utility-connected temp services compared to ERCOT-zone cities.
Rural counties. Many rural Texas counties have no building department and no permit requirement for electrical work on agricultural land. But on commercial property in those counties, state fire marshal rules still apply, and the work still needs a licensed electrician. Do not read rural as unregulated.
Frequently asked questions
Do you need a license for temp power in Texas?
Yes. Texas requires a TDLR electrical license for any compensated electrical work, including temporary power installations that connect to a structure's wiring or a utility service point. The homeowner exemption for a single-family residence does not cover contractors, event companies, or construction firms. The Electrical Contractor entity license and a sponsoring Master Electrician are both required to pull permits.
How much does temp power cost in Texas?
TDLR license renewal runs roughly $40 to $140 by class (Journeyman, Master, or Electrical Contractor). Local permit fees range from about $50 in small counties to $500-plus in major cities. Generator rental adds $800 to $2,500 per month for a 20 to 50 kW unit. Transfer switch installation by a licensed electrician typically runs $500 to $2,000. Confirm current TDLR fees before budgeting.
How long does temp power take in Texas?
TDLR online renewals process in a few business days when all documentation is complete. Local permit timelines vary widely: small counties may issue same-day, while Austin and Dallas can run several weeks in peak periods. Utility meter installation by the TDU (Oncor, CenterPoint) adds another 3 to 10 business days after inspection approval. File electronically and start early to cut delays.
How often do you renew a TDLR electrical license in Texas?
Every two years. TDLR sends a renewal notice about 90 days before expiration. Renewal requires 8 hours of continuing education per cycle for Journeymen and Masters, plus current insurance for Electrical Contractor licensees. Missing the deadline triggers a late fee. Letting the license fully lapse typically forces reapplication instead of renewal, which is longer and costs more.
Can a Texas electrical contractor work across the whole state with one license?
Yes. TDLR licensing is statewide after the 2017 consolidation of electrical licensing authority. One TDLR Electrical Contractor license covers all Texas jurisdictions. Individual cities still control permits and inspections, but you do not need a separate city-level contractor license to work across Houston, Dallas, Austin, and San Antonio.
What CE is required for TDLR electrical license renewal?
Eight hours of continuing education per two-year cycle for Journeyman and Master Electricians. TDLR keeps a list of approved CE providers in the MyLicense Office portal. Courses must be complete before you renew; you cannot renew first and finish CE later. Take CE at least 60 days before renewal so the provider has time to upload your completion record to TDLR's system.
Does Texas require workers' compensation for electrical contractors?
Yes, for TDLR Electrical Contractor license purposes. Texas generally does not mandate private employers carry workers' compensation (Texas Labor Code Chapter 406), but TDLR requires it as a condition of the Electrical Contractor license. The certificate must be on file with TDLR. An approved alternative may be accepted; confirm requirements in 16 TAC Chapter 73 or directly with TDLR.
What NEC edition does Texas use for temp power?
Texas adopts the NEC, but local jurisdictions control which edition applies to permits. In recent years, many Texas cities use NEC 2017 or NEC 2020; some have moved to NEC 2023. For temporary wiring, NEC Article 590 is the controlling section regardless of edition. Confirm the adopted edition with your specific Authority Having Jurisdiction before designing the installation.
Who do you call first for temporary utility power in Texas: the utility or the city?
The city (AHJ) first, always. You need a permit, then an electrical inspection, then an inspection release before the Transmission and Distribution Utility (Oncor, CenterPoint, AEP Texas) will set a temporary meter. Calling the TDU before you have inspection clearance wastes time. In San Antonio, CPS Energy is the municipal utility, so it is a bit simpler, but the inspection-first sequence still applies.
What happens if your Texas electrical license lapses before renewal?
TDLR allows late renewal with a late fee for a limited window after expiration. If the license lapsed too long ago, you may need to reapply from scratch, which can include retesting. Working with a lapsed license violates Texas Occupations Code Chapter 1305 and can bring civil penalties and a TDLR enforcement action. Check your specific license class rules in 16 TAC Chapter 73.
Can a homeowner set up temp power on their own property in Texas without a license?
Only for their own single-family residence. Texas Occupations Code § 1305.003 exempts homeowners working on their own home. This does not extend to duplexes, rental properties, or any commercial property. It also does not allow unlicensed work if the homeowner hires help. If you pull a permit and fail inspection, the AHJ can require a licensed electrician to correct and re-inspect the work.
Are there different temp power permit requirements for events vs. construction in Texas?
Generally, yes. Construction temp power usually uses a temporary service permit tied to the main building permit. Event power (concerts, festivals, outdoor markets) often falls under a separate temporary use or special event permit issued by the city, and may also require a fire marshal inspection on top of the electrical one. Some cities require a licensed electrician of record named on the event permit. Confirm with your city's permitting office.
How do Texas temp power costs compare to other states?
TDLR renewal fees are moderate next to states like California, which charges higher contractor license fees through the CSLB. States like Arkansas have lower overall fee structures. Local permit fees in Texas major cities are competitive with other Sun Belt metros. The biggest variable is the deregulated electricity market: utility-connected temp service in ERCOT Texas involves more entities and steps than in states with vertically integrated utilities.
