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.

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.

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.
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.
For electric in Seattle, the answer is Seattle City Light at 90% of addresses we checked.
