LAKE PLACID — There will be a 30-minute power outage on the Mirror Lake side of Lake Placid’s Main Street from 6 to 6:30 a.m. Tuesday morning.

Tuesday’s half-hour outage — which will affect Main Street buildings from Ben and Jerry’s to the Golden Arrow Lakeside Resort — will be the first of 16 expected half-hour outages to take place on the village’s main drag over the course of the next two to three years as crews work to repair the transmission line that feeds power to most of Main Street, according to village Electric Superintendent Kimball Daby.

Village electric crews are replacing eight 33-year-old metal enclosures located behind several Main Street businesses. The enclosures connect to a transmission line that runs underneath Mirror Lake’s surface. Each enclosure replacement will require two half-hour outages, according to Daby.

Daby said completion of the project could take up to three years, depending on the weather. The lake must be warm enough for crews to access the submerged portions of the transmission line, and Daby said electric crews will avoid performing replacements during the busy tourism months of July and August. That leaves June, September, and October as the only windows for replacement work, according to Daby.

The new enclosures will make it safer for electric department employees when accessing these enclosures in the future, Daby said.

The first metal enclosure to be replaced is located behind the Lake Placid Public Library, which is at the transmission line’s halfway point. Replacement work for this enclosure will require two half-hour power outages scheduled two weeks apart — the first on Tuesday and another in two weeks, with the date to be announced as weather permits.

While Tuesday’s outage — and the subsequent outage in two weeks — will affect the lake side of Main Street from the Golden Arrow to Ben and Jerry’s, the remaining 14 outages would likely affect smaller portions of Main Street’s lakeside strip as more and more enclosures are replaced.

“Each time, they’re going to get smaller and smaller,” Daby said of the outage areas.
