The Chelan Public Utility District in Washington began its county-wide fiber-optic network build. They have since passed some 80% of the county but are temporarily pausing expansion efforts. Chelan is a rural county and the network is not expected to break even for quite some time.
In Washington, state law limits the powers of public utility districts to offer broadband. As with communities in Utah, these public sector entities are forced to operate an open access network and are unable to offer services directly. While the open access model is a great one for some communities (and one we encourage when the numbers work), it can be difficult to implement depending on local circumstances.
