MeetingNov 4, 2026

The board continues weighing whether to bury overhead power lines, which costs a lot up front but can improve reliability during storms and fires. The discussion could shape future electric rates.

Board of Public Utilities — September 16, 2026

August's outage review showed mysterious short underground faults in White Rock, aging 1970s cable nearing failure, and concerns that SAIDI will hover around the 60-minute target until old cable is replaced.

MeetingAug 19, 2026

Board of Public Utilities — August 19, 2026

An old concentric-neutral cable failed near Aragon and Grand Canyon, blacking out much of White Rock; crews replaced it in three hours. Separately, about 60 street lights are out while newly hired staff work through the backlog.

MeetingJul 28, 2026

County Council - Regular Session — July 28, 2026

The consent agenda included a power purchase agreement of up to $9.2 million for August–September 2026 power pool load, an $849,570 piping project at the Los Alamos Switching Station, $1 million in power line tree trimming over seven years, and extension of the DOE Electric Coordination Agreement. These keep the county's electric system running and reduce wildfire risk near power lines.

MeetingJun 17, 2026

Board of Public Utilities — June 17, 2026

Staff estimated it would cost roughly $80 million — possibly double with rock — to bury all overhead power lines in the county, with nearly 2,000 secondary service drops to homes adding $6,000–$10,000 each. Board members questioned whether benefits justify the cost, noting new development already installs underground lines.
