Here's the setup that surprises new Seattleites: your power and your gas come from two different outfits. Electricity is Seattle City Light, the utility the city itself owns, and it showed up at every address we sampled. Gas, where a home has it, is Puget Sound Energy, a separate, investor-owned company. Water and sewer both run through Seattle Public Utilities across the addresses we checked. Four services, three names, and no shopping around, because Washington doesn't do retail choice.
Seattle went into the electricity business itself more than a century ago, and that decision still shapes your bill. City Light draws heavily on hydropower from dams in the Cascades, a big reason Washington rates sit among the lowest in the country. As the city grew up its hills and around the Ship Canal, that publicly owned grid grew with it, so newer neighborhoods and old ones alike land on the same electric utility.

Based on 12 sampled Seattle addresses spanning ZIP codes 98102, 98107, 98108, 98115, 98116, 98118, 98119, 98125, 98126, 98133, 98144, 98199 (2026-07-20). Yours may differ — the Seattle lookup is the tiebreaker.
City Light's territory follows the city but doesn't stop cleanly at the line; it also serves a handful of nearby areas, while some spots just outside Seattle fall to other utilities entirely. Cross into unincorporated King County or a bordering town and the electric provider can change.
The one-minute fix: run your Seattle address through the lookup and skip the guessing.
Before the boxes pile up in your new Ballard or Beacon Hill place, run this quick checklist so utilities aren't the thing you forgot.
At every one of the Seattle addresses we sampled, Seattle City Light was the electric utility. The exact Seattle provider depends on the address.
Generally no — Seattle electric territory is fixed by address: the utility holding your Seattle block is your utility, and at every one of sampled Seattle addresses that was Seattle City Light — Seattle is a one-signup town.
At every one of the Seattle addresses we sampled, Seattle Public Utilities was the water provider — sewer included. Other districts take over around Seattle's edges, so check your block.
No — at every one of the sampled Seattle addresses, PSE was the gas utility, but plenty of Seattle homes are all-electric and never open this account.
Seattle City Light, the city's own municipal utility, showed up at every address we sampled across Seattle. Because Washington has no retail choice, you don't pick an electric company; your address determines it, and inside the city that's City Light. Its heavy reliance on hydropower is a big part of why Washington's rates rank among the nation's lowest. Use the lookup to confirm your exact address.
Not the same company. Your electricity is Seattle City Light, but natural gas, in homes that have it, comes from Puget Sound Energy, a separate investor-owned company. Plenty of Seattle homes are all-electric and skip gas entirely, so you may only deal with City Light for energy. Where gas exists, PSE handled it at every address we sampled. Check the lookup to see what your address actually needs.
Both came back as Seattle Public Utilities, water and sewer alike, at every address we sampled across the city. Like your electricity, this isn't something you shop for; Washington has no retail choice, so your address sets the provider rather than you choosing one. Water and sewer can shift right at the city's edges, though, so it's worth running the lookup on your exact address instead of assuming the city line settles it.
