Panel upgrades, EV chargers & whole-home generators — plus the WPI-8/TWIA windstorm-permitting know-how Island work actually needs. Permits handled, inspection included.
TriCoast Electrical is a licensed master electrician serving Galveston Island and the Galveston Bay corridor — 27+ years of experience, TDLR EC License #EECELE00037785. Whether you're upgrading an older panel on the East End, putting a Level-2 charger in a West End garage, or you've finally had enough of losing power every storm, we do the high-stakes jobs right: pulled permits, code-correct work, and a real warranty behind it.
Not always the cheapest quote — but permitted, to code, and warrantied.
We lead with the jobs Island homeowners actually search for — and we'll tell you straight whether you even need the big one before we quote it.
"My panel is full." "Is my old box safe?" "It was sizzling." If your service is maxed out, or it's a Federal Pacific (FPE), Zinsco, or Stab-Lok panel your insurer has flagged, we replace it to code — typically a 200-amp upgrade, with CenterPoint coordination handled. We start with a load calculation, not a sales pitch.
$1,183–$1,972 typical See panel upgradesA properly permitted Level-2 install that passes inspection — not a box-store hack. Most installs don't need a panel upgrade; we verify that with a load calc first. Charging on the Island has its own detail (older panels, garage runs, occasional windstorm-permit triggers on exterior work), so we built a dedicated page for it.
$552–$1,379 typicalThe Island is exposed, and it loses power. After Beryl, "I can't go through that again" is the most common thing we hear. We size, install, and permit standby generators with an automatic transfer switch — so you're not outside fiddling with anything in the middle of a storm.
See generator installationPlus the rest of the work: whole-home surge & GFCI/AFCI protection, grounding, lighting & ceiling fans, outlets & switches, electrical inspections, remodel & new-construction wiring, and commercial finish-outs. One licensed local team, permits and inspection included.
Here's the part the thin local sites don't explain — and the reason the wrong electrician can cost you far more than their quote.
If you're doing new construction, adding solar, or doing major exterior electrical work in Galveston jurisdiction, it generally needs WPI-8 windstorm certification from the Texas Department of Insurance. That certification isn't bureaucratic box-checking — it's the chain that makes your home insurable. The Texas Windstorm Insurance Association (TWIA) won't issue a windstorm policy on non-compliant work. And the City of Galveston requires the contractor doing the work to be properly bonded and insured.
So the real cost of hiring wrong on the Island isn't a slightly higher invoice. It's uninsurable work, a failed inspection, or a stalled sale — the kind of problem that's expensive and slow to unwind after the fact.
TriCoast handles this end-to-end: the certified-contractor requirement, the WI-1/WPI-8 inspection step, the City of Galveston bonding/insurance side, and the CenterPoint coordination — so your work is permitted, certified, and insurable from the start.

Hurricane Beryl (July 2024) knocked out power for ~2.2 million CenterPoint customers. The Island sits right in the path, and it goes dark when the grid does. Homeowners around here describe it plainly: "We lost power for eight days." "You can't handle five days of losing power in this kind of heat."
A whole-home standby generator with an automatic transfer switch fixes that — power restores itself, no manual switchover, nothing to fiddle with during the storm. As one local homeowner put it, it's "peace of mind, just like homeowners insurance."
We keep this short here on purpose — for sizing, fuel, runtime, and maintenance detail, the generator installation page does the real work.
The wedge, in our customers' own words: no gouging, no upsell, no surprises.
That stays with your work, and with the house at resale.
If you don't need the panel upgrade, we'll tell you. We'd rather be the honest call than the big sale.

Both techs were very knowledgeable and professional from start to finish. They left the job site clean and all work was tested and reviewed with us before they left. My wife and I were extremely impressed. I would recommend TriCoast to all my friends and family.
TriCoast did an amazing job. Donald was so polite and his wife was very quick to reply to emails and requests. We were so impressed that we will be using TriCoast Electrical Services to handle all of our electrical needs in the house we are purchasing!
Donald is the best. He is very knowledgeable in his field and listens and answers any and all questions. Thank you for getting us all fixed up!

We work across Galveston Island and the broader Galveston Bay / South Houston corridor:
Confirm which Island areas are genuinely served — East End, West End (Beach Side & Bay Side), Jamaica Beach, Tiki Island, Bayou Vista — before listing as served.
Don't see your area on the list? We likely cover it — call and ask. Our coverage runs the whole corridor, from the Island across to the mainland Bay Area cities, where most of our work is based.
No trip-fee games, no pressure, no "three ridiculous options."

Generally, yes — for new construction, solar, and major exterior electrical work in Galveston jurisdiction. WPI-8 certification (via the Texas Department of Insurance) is what keeps the work insurable: TWIA won't issue a windstorm policy on non-compliant work. TriCoast handles the certified-contractor requirement and the WI-1/WPI-8 inspection step end-to-end.

A good contractor pulls their own permit. In Texas, only a registered master electrician can pull an electrical permit — the homeowner legally can't — so an electrician asking you to do it is a red flag. The permit stays with the work and with the house at resale. We pull it. More on Texas electrical permits →
Panel upgrades typically run $1,183–$1,972; EV charger installs $552–$1,379. We quote off the actual job, not a phone guess. For Island-specific EV detail, see our EV charger installation page.
Often yes — most homes don't need a panel upgrade for an EV charger, and we lead with a load calculation to confirm it before we ever quote one. We'll flag the real triggers: a full panel, or a dangerous FPE/Zinsco/Stab-Lok box (the kind insurers flag). Panel upgrades →
After Beryl (~2.2M CenterPoint outages), this is the most common call we get. We size a whole-home standby generator with an automatic transfer switch — power restores itself, no fiddling in the storm. It's peace of mind, like insurance for the house. Generator installation →
