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:

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.
First distribution pole at IHPW
On Sunday, August 7, 2022 the first pole for the future distribution line from Inuvik Wind was installed
Structural steel frame
The wind turbine will sit on this structural steel spider web frame
Wind turbine on barge at MTS Hay River
The wind turbine blades were transported by barge from Hay River to Inuvik in the summer of 2022 
Structural steel frame
Installation of the structural steel spider frame that will support the wind turbine continued despite the arrival of winter
IHPW Signage
Funding support from the Government of Canada is critical to adding the wind turbine to the generation supply in Inuvik
Crane on site
The crane that will help erect the wind turbine tower and blades in already onsite
Distribution line work continues
Installation on the distribution line connecting the wind turbine to the rest of the local electricity system continued throughout the winter of 2022/23
Access road -- March 30, 2023
Construction of the access road to the Inuvik High Point Wind site continued throughout the winter of 2022/23 and into the spring
Road to turbine pad
Tremendous progress is being made on the roadways at the site, including the approach to the wind turbine pad
Turbine base in transit
Starting on May 6, 2023, major components that had been in storage were transferred to the Inuvik Wind site
Turbine base being erected
The first part of the turbine shaft being lowered into place on the steel infrastructure base.
Raising third tower section
The tower to support the turbine blades was erected in May 2023
First turbine blade arrives at site
On May 29, the first turbine blade arrived onsite
Tower ready for blade installation
The tower is now ready for turbine blade installation
Last step before blades installed

Taltson Refurbishment

New Taltson turbine shaft has been manufactured

The new camp for those who will be working on the overhaul can be seen on the left side of this photo. The number of workers  required to complete the overhaul exceeds the capacity of the former camp. The Taltson hydro unit can be seen in the top right of the photo.  
Taltson Winter Road
In the winter of 2023, the Taltson Winter Road was constructed so that key components such as the new turbine and turbine base could be transported to site in advance of the overhaul
Winter Road 2023
Assembly of the rotor
Assembly of the rotor, a key component in a hydro unit, occurred in the first quarter of 2023-24
Rotor assembly
Rotor being tilted
Once assembled, the rotor was tilted upright to free up floor space for other work required during the overhaul

Sachs Harbour -- new diesel plant

New diesel plant in Sachs Harbour
Commissioning of a new diesel plant in Sachs Harbour began in early 2022
New plant -- October 2022
Construction of the new plant continued throughout 2022
New plant interior -- November 2022
The new plant has three high-efficiency generators.
Plant interior -- November 2022
The new plant will replace an older plant that has reached its end of life.


Lutsel K'e -- new diesel plant

New diesel plant in Lutsel K'e
Construction of a new, high efficiency diesel plant in Lutsel K'e began in 2021
Inside of plant
Installation of equipment, including three new high-efficiency generators occurred in 2022
