Port And Industrial Loads
National City is the most industrial city we cover, and the work reflects it. The marine terminal, the shipyards, the auto logistics yards and the light manufacturing along Mile of Cars and the harbor frontage all generate a different class of job from a residential remodel: three-phase, higher amperage, and often on a site that has to keep operating while the work happens.
Three-phase temporary service is the default here rather than the exception. Welding plant, compressors, hoists and process equipment do not run sensibly on single phase, and the distribution has to be planned as a system: the temporary service, then properly rated distribution out to the work, with GFCI protection at every point a person plugs in. We build that as one design rather than adding boxes as the job grows, which is how it usually goes wrong.
Salt is a serious problem on the waterfront and it is worse here than on the open coast, because industrial sites combine salt air with dust, forklift traffic and the occasional knock. Enclosures need to be sealed, terminations need anti-oxidant compound, and anything at ground level in a working yard needs physical protection. We build to that standard because on a terminal site nobody is going to notice a corroding lug until it takes something out.
A lot of National City work is on live sites, which changes the sequencing more than anything else. Shutdowns get scheduled around production or vessel movements, not around our convenience, and that frequently means night and weekend change-overs. A generator rental is often the only way to keep the operating side of a facility running while its service is worked on, and the sizing on those has to account for motor starting rather than just running load.
The larger yards run around the clock in stretches, and lighting on an industrial site is a safety system rather than a convenience. Light towers positioned to cover traffic routes and work areas without glaring into an operator’s eyes is a genuine skill, and getting it wrong on a yard with moving plant is dangerous.
Security on industrial and port-adjacent sites is a standing concern given the value of what sits on them. Cellular security cameras that work without site internet, positioned to cover the gate and the material lay-down, are a standard part of what we deliver here rather than an add-on somebody asks about later.

Frequently Asked Questions
What is temporary power?
Temporary power is a permitted, metered electrical service installed on a construction site before the building has a permanent one. Usually that is a temporary power pole carrying a meter socket, main breaker, panel and GFCI-protected outlets, grounded and braced to SDG&E’s standard. It runs the trades, the tools and the site trailer through the build and comes out once the permanent service is energized.
How long does it take to get temporary power in San Diego?
Allow two to four weeks from go-ahead to an energized pole across most of the county. The electrical permit is usually quick; the SDG&E meter set is the part that carries a queue and it is why we file the service application as early as your drawings allow. If your start date will not wait, we will bridge it with a generator and take that off rent the week the pole goes live.
Do you handle the permit and the SDG&E application?
Yes, both, on every job. We pull the electrical permit with the city or the county, file the service application with SDG&E including the site plan and load information they need, and meet the inspector on site. You do not fill anything in.
How much does temporary power cost?
A standard residential temporary power pole in San Diego County typically lands between $1,200 and $3,000 installed, permitted and removed at the end. Amperage, the distance from the point of connection, and whether the utility is overhead or underground are what move the number. Larger and three-phase commercial services are quoted per project.
Do you serve all of San Diego County?
Yes. Crews run daily to Chula Vista, Oceanside, Escondido, Carlsbad, El Cajon, Vista, Encinitas, National City, Poway, La Jolla and Coronado, plus everywhere in between and the back country beyond. If you are not sure whether we reach your site, call and ask — the answer is usually yes.
Is it cheaper to rent a generator or install a temp pole?
It depends almost entirely on how long the job runs. Below roughly two months, generator rental usually wins because it avoids the install and the utility wait. Past that, a metered temporary service is cheaper and quieter, and the crossover comes sooner on a site with a big load. We will run both numbers against your actual schedule rather than steering you to one.
Can you deliver everything on one order?
Yes, and most sites do. Power, lighting, cooling, WiFi and cameras on one quote, one delivery run and one point of contact costs less than sourcing each from a different yard, and it means one person is accountable when something needs moving as the build changes.
