In Plano, electric delivery is handled by Oncor — and since Plano sits in Texas's deregulated market, you pick your own Plano retail plan; Atmos Energy is Plano's natural-gas utility; City of Plano handles Plano's water and sewer. The exact lineup depends on your Plano address — even nearby Frisco and Garland answer differently.

Plano is about as predictable as Texas utilities get: a built-out Collin County city where electricity is deregulated with a single wires company, gas comes from the regional utility, and the city handles water and sewer everywhere. There's little of the district patchwork that complicates its newer neighbors to the north.
Plano built out decades ago, which is why its utility map is so settled: no new territory is being carved up, and the Legacy-area towers run on the same lineup as the 1980s cul-de-sacs. What still trips people up is arriving from a city that does things differently — Garland's municipal electric, Frisco's co-op patchwork — and assuming Plano matches.
In Plano, timing shapes utility setup as much as geography. Moves cluster around the school calendar — out in late May, back before Plano ISD starts in August — which drops most lease turnovers into the hottest weeks of the year, when the air conditioning runs before the boxes are open. That's a bad moment to pick an electric plan carelessly: Oncor runs the wires, but the retail plan you choose decides how a summer of nonstop cooling gets billed. And because so many of the city's seventies-through-nineties houses came with gas furnaces and water heaters, an Atmos Energy account matters even in August — you'll notice its absence at the first cold snap. The City of Plano water account, meanwhile, announces itself once the sprinklers kick on.

Oncor — Plano's TDU — owns the wires here, the same delivery setup as Plano's neighbors Dallas and Irving, and restores Plano outages ((888) 313-6862) whoever you pay. Your separately chosen Plano plan (compare at Power to Choose) sets the rate on your Plano bill — full wires-vs-plans explainer here.
Plano's checklist is the standard North Texas three-step, with few surprises waiting.
Oncor is the TDU for Plano — the wires-and-meters utility — at every one of the Plano addresses we sampled. You pick the retail plan that sets your Plano rate; Oncor delivers either way.
At every one of the Plano addresses we sampled, City of Plano was the water provider — sewer included. Other districts take over around Plano's edges, so check your block.
No — at every one of the sampled Plano addresses, Atmos Energy was the gas utility, but plenty of Plano homes are all-electric and never open this account.
No — Plano is fully in the deregulated market. Oncor delivered electricity at every Plano address we sampled, and you choose the retail plan on top of that delivery.
Through the City of Plano, which was the water and sewer provider at every sampled address. The city takes service requests directly — have your move-in date and lease or closing paperwork ready.
Not in our sampling — addresses from Windhaven Parkway to Los Rios Boulevard returned the same lineup: Oncor delivery, Atmos gas, city water. What does change across town is which retail electricity plans make sense for your usage, and that part is up to you.
Not in our sampling — addresses on both sides of US 75, from the older neighborhoods near downtown Plano to the Legacy-area towers, returned the same lineup. Plano built out decades ago, so there's none of the edge-of-town patchwork you see in Frisco or McKinney. The practical difference between homes is usage, not providers: a 1980s house and a new high-rise call the same companies but shop very different electricity plans.
