Project Development Timeline

Bulk Transmission Development in Washington

The electrical grid in Washington is part of the Western Interconnection power grid and the Western Electricity Coordinating Council (WECC). WECC includes the provinces of Alberta and British Columbia, the northern portion of Baja California, Mexico, and all or portions of the 14 Western states between. The WECC is the Regional Entity responsible for coordinating and promoting Bulk Electric System reliability in the Western Interconnection, including in Washington. In addition, WECC provides an environment for coordinating the operating and planning activities of its members as set forth in the WECC Bylaws.

In addition, some transmission owners in Washington are part of the Northern Tier Transmission Group (NTTG). The NTTG is a group of transmission providers and customers that are actively involved in the sale and purchase of transmission capacity of the power grid that delivers electricity to customers in the Northwest and Mountain States. Transmission owners serving this territory work in conjunction with state governments, customers, and other stakeholders to improve the operations of and chart the future for the grid that links all of these service territories.

Avista, Pacificorp, Puget Sound Energy, Tacoma Public Utilities, Bonneville Power Administration, Columbia Grid, Northern Tier Transmission Group, and Seattle City Light provide transmission in the state of Washington.
