  Northwest Territories Power Corporation – Snare Cascades – April 2016
American Governor Awarded NTPC Digital Governor and Unit Control Conversion Project

Ivyland PA – American Governor Company (AGC) has been selected to provide a Governor conversion and a Unit Control system for Northwest Territories Power Corporation’s (NTPC) Snare Cascades facility. Located in a remote area, 145km (90 miles) northwest of Yellowknife, Northwest Territories, this single-unit powerplant is located on the Snare River. It is accessible by airplane from April through November and via ice road truck during the winter months, when daytime temperatures of -30°C (-22°F) are commonplace.

The 30MW Snare Project consists of four hydro plants that are operated from their Dispatch Center in Yellowknife. The Snare River winds its way into the Great Slave Lake. American Governor has already converted two (2) of the plants (Snare Falls and Snare Forks) and the precise governor control, smart control algorithms, and advanced digital communication have enabled NTPC’s Grid Operators to tailor hydro unit operations to balance the varying needs of the regional grid.

The same equipment design will be employed at Snare Cascades. When the retrofit is complete, NTPC will have another 4.5MW of grid-responsive hydropower. This project continues American Governor’s industry-leading ability in designing, building and delivering grid-responsive Governor and Unit Control solutions for clients all across North America, and around the world.
