Temp power cost in Texas: what you'll actually pay

Last updated 2026-08-18

How much does temp power cost in Texas?

The honest answer is: it depends on three things. Generator size, how far you are from a utility connection, and whether you're renting equipment or buying it.

For a small residential or light commercial job, a 20 to 45 kW diesel generator rental runs roughly $150 to $400 per week in Texas, according to national equipment rental rate surveys ^[1]. Add fuel at current diesel prices (the U.S. Energy Information Administration tracks weekly retail diesel by region) ^[2], a temporary service panel ($100 to $300 to rent, $400 to $900 to buy), and electrical labor for the connections.

Larger construction sites needing 100 to 500 kW push weekly generator rental to $600 to $2,500 or more. Machines at the top of that range burn fuel fast. A 500 kW diesel generator at 75% load burns roughly 35 gallons per hour ^[3], so on a multi-week job the fuel bill can dwarf the equipment rental.

Here is a realistic range table for common Texas temp power scenarios:

Scenario	Generator size	Weekly rental est.	Permit fee est.	Licensed labor est.
Residential construction or remodel	20 to 45 kW	$150, $400	$50, $150	$300, $600
Small commercial build	45 to 100 kW	$300, $750	$75, $200	$500, $1,200
Large construction site	100 to 300 kW	$600, $1,800	$100, $200	$1,000, $3,000
Event or festival (400A service)	100 to 500 kW	$800, $2,500	$75, $200	$800, $2,500

These are market estimates, not quotes. The real numbers move with fuel prices, the local labor market, and your specific site. Get at least three bids from licensed electrical contractors before you sign anything.

One cost that surprises first-timers: transformers and cable. If your site needs 480V three-phase distribution, you're adding a step-down transformer ($300 to $1,500 to rent), cam-lock feeder cables, and a distribution panel on top of the generator. If you're building your own kit rather than renting, TempPowerPath's Cable + Fuel + 480V Kit runs a flat $179 one-time and covers the documentation side of that equipment selection.

Do you need a license for temp power in Texas?

Yes. Texas requires a licensed electrician to connect temporary electrical service. The Texas Department of Licensing and Regulation (TDLR) issues electrical contractor and electrician licenses under Chapter 1305 of the Texas Occupations Code ^[4].

Chapter 1305 requires anyone who installs, erects, repairs, or alters electrical wiring or equipment in Texas to hold the appropriate license ^[4]. That covers temp power connections to a generator, a temporary distribution panel, or a utility temporary service pedestal. It is not a gray area.

Here is how the Texas electrical license ladder works:

License type	Who holds it	Notes
Apprentice Electrician	Trainee working under supervision	Cannot work unsupervised
Journeyman Electrician	Licensed individual who can work independently	Must work under a master or contractor for certain jobs
Master Electrician	Most advanced individual license	Can plan and supervise electrical work
Electrical Contractor	Business license	Required to pull permits and contract directly with owners

For a temp power hookup, you need an Electrical Contractor (the business) pulling the permit, with a licensed Journeyman or Master electrician doing the actual connection. You cannot legally do this yourself as an unlicensed person on commercial or most residential jobs.

Verify current requirements and look up licensed contractors through TDLR ^[4]. Rules do change, and individual cities sometimes stack extra local requirements on top of the state baseline.

How long does temp power take in Texas?

From the day you decide you need temp power to the day the generator is running and permitted, expect one to five business days in most Texas jurisdictions for a straightforward job. That assumes you already have a licensed contractor lined up and the equipment is available.

Here is where delays actually happen.

Permit processing is the most variable piece. Some Texas cities have online portals that issue same-day approvals for simple temporary service permits. Others want an over-the-counter submission and a two to five day review. A few smaller jurisdictions still route permits through a single building official who reviews twice a week. Call your local authority having jurisdiction (AHJ) before you schedule anything.

Equipment availability matters more than people expect. In summer (June through August especially), generator rental demand spikes hard after major storms and during heat events. Try to rent a 200 kW or larger machine during a grid emergency and lead times can stretch to one to three weeks. Build buffer into your schedule.

Inspection scheduling is the third variable. Some Texas cities offer next-day inspections. Others carry backlogs of three to seven days. Your electrical contractor should know the local inspection calendar, so ask them directly rather than guessing.

If you're connecting to a utility temporary service instead of a generator, add your utility's new service timeline. Utility temporary service installations in Texas generally take five to fifteen business days from application to energization, though that range is wide and varies by area.

What permits are required for temp power in Texas?

Most Texas municipalities require a temporary electrical permit before you install a temporary service pedestal or connect a generator to a structure's electrical system. The exact permit type varies by city or county.

In Texas, permitting authority for electrical work lives at the local level. The state sets the licensing rules through TDLR ^[4], but the permit itself comes from the city or county building department. Houston, Dallas, San Antonio, Austin, and Fort Worth all run their own permit portals and fee schedules.

Typical permit fees for temporary electrical service in Texas range from $50 to $200. Some jurisdictions charge a flat fee, others base it on the estimated cost of work or the amperage of the service. Confirm the exact figure with your local building department before you budget.

One thing that trips people up: if your setup involves a generator feeding a structure, even temporarily, many jurisdictions treat that as a temporary service that runs through the same permit process as a permanent service install. A generator on a flatbed powering only hand tools through extension cords may not trigger the same requirement, but the line is fuzzy and the AHJ call is the only one that counts.

The National Electrical Code (NEC), which Texas has adopted with amendments, addresses temporary installations in Article 590 ^[6]. Article 590 sets the safety rules for temporary wiring, including a requirement that all temporary wiring be removed immediately once the work it powered is finished.

What does generator fuel cost on a Texas job site?

Fuel is often the biggest ongoing cost for temp power, and it's the one most people underestimate at budget time.

The U.S. Energy Information Administration (EIA) publishes weekly retail diesel prices by region ^[2]. In recent reporting, retail diesel in the South Central states has ranged from roughly $3.20 to $4.50 per gallon depending on market conditions. Use the EIA weekly update rather than any number in this article, because diesel prices move.

Burn rates depend on generator size and load factor. A 45 kW diesel generator at 75% load burns about 3.0 to 3.5 gallons per hour ^[3]. Run that eight hours a day, five days a week, and you're at 120 to 140 gallons per week. At $3.75 a gallon, that's $450 to $525 per week in fuel alone for a relatively small machine. Scale up to a 150 kW generator and the numbers climb fast.

Ways to cut fuel cost in Texas:

• Natural gas generators are common on Texas sites with pipeline access. Gas usually costs less per equivalent BTU than diesel, and Texas has extensive pipeline infrastructure. The trade-off is that you need a utility connection or on-site storage.
• Load management matters. A generator running at 30% load burns almost as much fuel per kWh as one at 75% load. Right-sizing the machine to actual load saves real money.
• Propane works for smaller machines and remote sites, though propane prices swing and you'll need tank delivery logistics.

Fuel delivery is available in most Texas metros. On large or long-running jobs, a fuel supply contract with a commercial distributor usually beats buying retail.

Does Texas have a temp power license separate from a general electrician license?

No. Texas does not have a standalone temp power license. Temporary electrical connections fall under the same structure as all other electrical work in the state: an Electrical Contractor license (business entity) and a Journeyman or Master Electrician license (individual) ^[4].

What varies is the scope of work your license covers. A Journeyman Electrician can perform temp power hookups under the supervision of a Master Electrician or Electrical Contractor. A Master Electrician can supervise and plan the work. The Electrical Contractor entity pulls the permit.

For event or film production temp power (common in Austin, Dallas, and Houston), the same rules apply. There is no entertainment industry carve-out. The electrician making connections must be licensed under Chapter 1305.

One edge case worth knowing: Texas lets an owner-builder do electrical work on their own residence under certain conditions. That does not apply to commercial property, rental property, or any property you don't personally occupy. And even for owner-builders, the permit and inspection requirements still apply. Confirm the current owner-builder rules with TDLR or your local AHJ before you assume this fits your situation.

How does Texas temp power cost compare to other states?

Texas sits roughly in the middle of the national range for temp power costs. Here is why.

Licensed electrician labor in Texas is cheaper than on the coasts and higher than in some rural southern states. The Bureau of Labor Statistics 2023 Occupational Employment and Wage Statistics put the mean hourly wage for electricians in Texas at $27.87, against $42.15 in California and $22.10 in Arkansas ^[7].

Equipment rental rates track regional labor and logistics costs. Texas has a large rental market with multiple national chains (United Rentals, Sunbelt, BlueLine) operating heavily across the state, which keeps prices competitive.

Permit fees in Texas are generally modest compared to states with more aggressive fee schedules, though it varies widely by city.

The biggest Texas-specific cost factor is heat. Summer heat means generators work harder to carry cooling loads, fuel burn rises, and maintenance intervals get shorter. Budget for more fuel than you'd burn in a cooler climate.

For comparison reading, see how costs break out in temp power in Alabama, temp power in Georgia, and temp power in Arizona.

What is a temporary utility service and how is it different from a generator?

A temporary utility service is a meter and pedestal installed by your utility (Oncor, AEP Texas, CenterPoint, depending on location) that gives you grid power at a construction site before the permanent service is built. A generator is self-contained power you bring to the site.

Utility temp service is generally cheaper to run long-term because you pay retail electricity rates instead of fuel plus maintenance. In Texas, residential retail electricity rates have ranged from roughly 11 to 16 cents per kWh depending on provider and market conditions, though the ERCOT market is famously variable ^[8]. Generator-produced power on a small machine typically costs 30 to 60 cents per kWh once you fold in fuel and maintenance, so grid power wins by a wide margin on jobs that last more than a few weeks.

The trade-off is lead time and access. Utility temp service needs the utility to install the pedestal, which takes time (five to fifteen business days is a common estimate, but confirm with your specific utility). Remote sites may have no utility access at all. Generators can show up in 24 to 48 hours if equipment is available.

Many Texas projects start on a generator during early site work, switch to utility temp service once it's live, then stay on utility temp service until permanent service is energized. That's the most common approach on jobs longer than four weeks.

What safety rules apply to temp power in Texas?

Texas has adopted the National Electrical Code, and Article 590 applies specifically to temporary installations ^[6]. The NEC allows temporary electrical power and lighting during the period of construction, remodeling, maintenance, repair, or demolition of buildings, structures, or equipment.

Key Article 590 requirements that affect temp power setups:

• All temporary wiring must be removed immediately once the work is done. You cannot leave a temp service in place indefinitely.
• GFCI protection is required for all 125-volt, 15- and 20-ampere receptacles used by personnel.
• Cables must be protected from damage where they pass through doorways, windows, or similar openings.
• Temporary lighting cannot be supported by the wiring itself.

Beyond the NEC, OSHA's construction standards at 29 CFR 1926 Subpart K cover electrical safety on construction sites ^[9]. OSHA requires either an assured equipment grounding conductor program or GFCI protection on all construction site temporary power. That's a federal requirement sitting on top of the state code, and it applies in Texas or any other state.

Generator placement is a frequently cited safety issue in Texas. Carbon monoxide from generators kills people every year in the U.S. The Consumer Product Safety Commission has documented hundreds of CO deaths from generator misuse ^[10]. Keep generators outdoors, away from windows and doors, and never run one inside a structure or enclosed space.

How do I find a licensed temp power electrician in Texas?

The TDLR license search lets you look up any electrical contractor or electrician by name, license number, or company name ^[4]. It's the single most reliable way to confirm someone is actually licensed before you hand over a deposit.

Beyond the license check, here is what to verify.

Confirm the Electrical Contractor (business) license, not only the individual electrician's license. The contractor entity is the one legally authorized to pull permits and enter contracts with property owners.

Ask specifically about temporary power experience. Temp power setups have different demands than typical residential wiring, especially at higher voltages and larger service sizes. An electrician who mostly does residential remodels may have thin experience with 480V three-phase distribution or generator paralleling.

Get proof of insurance. Texas requires electrical contractors to carry liability insurance. Ask for a certificate naming you as an additional insured for the project duration.

On large temp power jobs, ask about OSHA 30 certification for the supervising electrician. It's not legally required, but it flags someone who has thought seriously about site safety.

TempPowerPath's documentation kits at /start include a contractor vetting checklist that covers the exact questions worth asking before you sign a temp power contract, which can save you from the most common hiring mistakes in this space.

Frequently asked questions

Do you need a license for temp power in Texas?

Yes. Under Texas Occupations Code Chapter 1305, all electrical work including temporary power connections requires a licensed Electrical Contractor (business) to pull the permit, with a licensed Journeyman or Master Electrician performing the work. There is no separate temp power license; the same structure covers all electrical installations. Verify current requirements through TDLR before hiring.

How much does temp power cost in Texas?

A typical Texas temp power setup runs $300 to $2,500 or more depending on generator size, site conditions, and job duration. A 20 to 45 kW generator rents for roughly $150 to $400 per week. Add fuel, a temporary distribution panel, licensed labor, and permit fees ($50 to $200). Larger commercial sites with 100 to 500 kW needs can spend $1,000 to $5,000 per week all-in. Get multiple bids.

How long does temp power take in Texas?

For a generator-based setup, expect one to five business days from permit application to energized equipment, assuming a licensed contractor is ready and equipment is available. Utility temporary service typically takes five to fifteen business days from application to energization, but that range varies significantly by utility and location. Summer months compress equipment availability, so build buffer into your schedule.

Can I install temp power myself in Texas without a license?

Not legally on most jobs. Texas Occupations Code Chapter 1305 requires a licensed electrician to install electrical connections, including temp power hookups. An owner-builder exception exists for work on your own occupied residence, but it does not cover commercial property, rental property, or construction sites. Doing unlicensed electrical work on a job site also creates OSHA liability exposure.

What permit do I need for a temporary generator hookup in Texas?

Most Texas municipalities require a temporary electrical permit from the local building department. The state sets licensing rules through TDLR, but permits come from city or county building officials. Fees range from $50 to $200 in most jurisdictions, though some calculate them by amperage or estimated cost of work. Call your local AHJ to confirm what they require before scheduling your electrician.

How much does diesel fuel add to temp power costs in Texas?

Fuel is often the largest ongoing cost. A 45 kW generator at 75% load burns roughly 3.0 to 3.5 gallons per hour. At current regional diesel prices (check the EIA weekly retail price data for South Central states), that's about $450 to $525 per week for a modest machine running eight hours a day, five days a week. Larger generators burn proportionally more. Right-sizing your generator to actual load cuts fuel cost significantly.

Is temp power cheaper from a generator or from the utility in Texas?

Utility grid power is almost always cheaper per kWh for jobs longer than a few weeks. Texas retail electricity rates have ranged roughly 11 to 16 cents per kWh, while generator-produced power typically costs 30 to 60 cents per kWh all-in. The trade-off is lead time: utility temp service takes five to fifteen business days to set up, while a generator can be on site in 24 to 48 hours if equipment is available.

What GFCI rules apply to temp power in Texas?

National Electrical Code Article 590, adopted by Texas, requires GFCI protection on all 125-volt, 15- and 20-ampere receptacles used by personnel at temporary installations. OSHA's 29 CFR 1926 Subpart K also independently requires GFCI protection or an assured equipment grounding conductor program on all construction site temporary power. Both rules apply simultaneously on Texas job sites.

What is the Texas Electrical Contractor license and who needs it?

The Electrical Contractor license is a business-level license issued by TDLR under Chapter 1305 of the Texas Occupations Code. Any company that contracts to perform electrical work, pulls permits, or bills clients for electrical installations in Texas must hold it. Individual electricians need separate Journeyman or Master licenses. On a temp power job, the Contractor entity pulls the permit; a licensed individual does the work.

Can a generator be used for temp power at a Texas event or festival?

Yes, and it's common in Austin, Dallas, and Houston for outdoor events. The same licensing rules apply: a licensed Electrical Contractor must oversee connections, and a Journeyman or Master Electrician must make them. There is no entertainment or event industry exemption in Texas electrical law. Permit requirements depend on the venue and local AHJ, so confirm with your city's building department well before the event date.

How do Texas temp power costs compare to California or Florida?

Texas electrician labor is much cheaper than California (mean hourly wage $27.87 vs. $42.15 per BLS 2023 data) and modestly higher than some southeastern states. Equipment rental rates are competitive because Texas has a dense market of national rental chains. Florida and Texas are roughly comparable in overall temp power cost. California tends to run 40 to 60% higher due to labor, permitting, and prevailing wage rules on larger jobs.

Are there carbon monoxide risks with temp generators in Texas, and what does the law say?

CO poisoning is a documented, serious risk. The CPSC has recorded hundreds of generator-related CO deaths nationally. NEC Article 590 and OSHA construction standards both require generators to run outdoors, away from windows, doors, and vents. Keep generators at least 20 feet from any opening into an occupied space. Never run a generator inside any structure, tent, or semi-enclosed area, regardless of job duration.

What is the NEC Article 590 rule about removing temp power?

NEC Article 590 says temporary electrical power installations must be removed immediately once the construction, remodeling, maintenance, repair, or demolition work that justified them is complete. You cannot leave a temporary service in place indefinitely and call it permanent. Texas has adopted the NEC, so this removal requirement applies statewide. Failing to remove temp wiring on schedule can create inspection and liability issues.
