Capital Projects

NTPC owns and operates a large number of physical assets. The list of assets includes hydroelectric facilities, transmission lines and power poles, diesel generators, solar arrays, transformers, bucket trucks and many other things. These assets require regular maintenance but may also need to be replaced or refurbished  at some point in time. As a result, NTPC completes projects every year to ensure that electricity can continue to be reliably provided to customers in customers across the NWT. 

Among the major projects that have recently been completed, are underway or are expected to begin in the near future:

Snare Forks Unit 1 Refurbishment

Machining of steel ring

Inuvik Wind Project

Turbine arrival in Hay River
Components of the wind turbine were stored in Hay River before being transported by barge to Inuvik in the summer of 2022
Turbine blade
Turbine blade arrived in Hay River in November 2021.
Piles and thermosyphons at Inuvik Wind site
Grey piles that will form part of the foundation of the wind turbine have been installed at the site. Thermosyphons (white poles) will help to protect the thermafrost beneath and around the turbine as well as help stabilize the structure.
