Even without these changes, Washington state's utilities and governments have already been able to sell Internet service, but mostly only on a wholesale basis - they can advertise, but only to direct you to third-party reseller ISPs.
In rural central Washington, several county electric utility government districts already offer gigabit to the home through their resellers (Chelan, Douglas, Grant among them). From my understanding, that infrastructure and the cheap hydro power attracted Microsoft to build multiple cloud data centers in Quincy, Grant County.
