Straight answers.

TESIM Electric is a licensed commercial electrical contractor based in Lakeway, Texas — the turnkey electrical partner builders and general contractors bring in for the full scope, focused on data centers, mission-critical facilities, power, energy, and solar across Texas, with a proven foundation in ground-up commercial construction, tenant finish-out, and service. We self-perform the commercial electrical scope and partner for specialized medium-voltage and substation work.

No. We’re a licensed, self-performing electrical contractor — not a staffing agency, workforce provider, or labor broker. Builders and GCs hand us the electrical scope and our own crews deliver it, start to finish.

Yes — data centers and mission-critical facilities are the market we’re built for and focused on, alongside power, energy, and solar work. Our track record is in commercial electrical construction, which is the same power distribution, switchgear, conduit, and structured pathways these facilities depend on. We self-perform that scope up to 600V and bring in trusted partners for medium-voltage and substation-class work.

Yes. Power, energy, and solar are part of what we’re focused on and built for. We self-perform the commercial electrical scope those projects need and bring in trusted partners for specialty renewable-energy work as required.

We’re based in the Austin area (Lakeway, Texas) and serve all of Texas — Austin, San Antonio, Dallas–Fort Worth, Houston, and everywhere in between.

Yes. We’re a licensed Texas electrical contractor (TDLR) with a Master Electrician on staff. We carry $2M–$5M in general liability coverage and can raise limits as high as a project requires, and we arrange bonding per job. Certificates of insurance and license details are available on request.

No — we can fulfill jobs of any size. We self-perform the commercial electrical scope with our own crews and scale up with trusted partners for specialized medium-voltage and substation work, and we scale insurance and bonding to match the project. Whether it’s a single tenant finish-out or a large mission-critical build, we size the team, coverage, and bonding to fit.

Our focus is commercial. Commercial buildings are wired in metal conduit and follow different code requirements than residential Romex wiring, and that’s the work we specialize in — small-to-mid-sized commercial construction and finish-outs.

We self-perform the electrical scope with our own licensed crews. For specialty scopes like excavation and trenching, we bring in and manage trusted partners so the whole package stays coordinated.

We self-perform standard commercial building power up to 600 volts — services, distribution, feeders, panels, branch circuits, lighting, and data/low-voltage pathways. Medium-voltage and utility/substation-class work is partnered or subcontracted as needed.

Yes — slab to finish. We handle the service entrance, distribution, rough-in, lighting, and trim, and carry the job through final inspection and turnover.

Both, but general contractors and builders are who we’re built for — a turnkey electrical sub for the full scope. We also work directly with owners and developers on finish-outs, remodels, and service work.
