August 30, 2017 – Nova Scotia Power is investing nearly $4 million to upgrade the Lequille hydroelectric system to ensure the facility’s “reliability, safety and efficiency”.

“We continually assess our facilities to determine if and when upgrades are needed to ensure we can safely and reliably deliver service to customers,” said Wes Trimper, hydro superintendent with Nova Scotia Power. “This investment in Lequille will support Nova Scotia Power’s efforts to transition to more renewable energy generation.”

The Lequille system consists of three storage reservoirs and a 3-mile canal that diverts water flow to a concrete intake structure. A wood stave penstock attached to the intake structure conveys water to the Lequille generating facility, which contains a water wheel connected to a 13MW generator.

Work taking place this year includes the refurbishment of the generator, replacement of the system’s pipeline and switchgear, and installation of a new control system and instrumentation. The project is expected to wrap up by the end of the year.

The Lequille powerhouse first opened in 1968, and is one of 33 hydroelectric generating stations located along 17 river systems across Nova Scotia, says the utility.
