New transmission line connects key Hanford substations
Energised 230-kV line strengthens grid link between central Hanford and off-site substations, boosting power reliability for waste treatment and cleanup operations.

USA, Washington, Richland: The Bonneville Power Administration (BPA), in collaboration with the US Department of Energy’s Office of Environmental Management at the Hanford Field Office, has energised a new 29-km (18-mi), 230-kV transmission line connecting two strategically important substations. One substation is located near the heart of Hanford’s operations, while the other sits outside the site’s perimeter, enhancing power delivery routes for critical infrastructure.
This connection between the central and external substations marks a significant step forward in modernising the site’s power grid. The newly energised line replaces an ageing 80-year-old system, ensuring reliable and efficient electricity supply for ongoing waste treatment and environmental remediation efforts at the Hanford Site.
The line’s dual-circuit tower design enhances grid resilience and supports essential facilities, most notably the Waste Treatment and Immobilisation Plant, which is preparing to vitrify radioactive tank waste into stable glass form. One circuit will be operated by Hanford Mission Integration Solutions (HMIS) to supply energy to core site operations, while BPA retains use of the second circuit for broader transmission network integration.
By directly linking the two substations, the project not only improves operational reliability but also supports long-term energy security for one of the United States’ most complex environmental cleanup sites.
