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

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
Turbine blade ready for installation
The first of three turbine blades is ready to be installed
Lift and rotation of hub
The hub is the piece of equipment in which the turbine blades are installed
Hub installed
First turbine blade installed
The first turbine blade was installed on June 4, 2023
Lifting of second turbine
Attaching the second turbine blade on June 5, 2023


Third turbine blade arrives onsite
The third turbine blade awaits installation


All three blades installed
On June 7, 2023, the third and final turbine blade was installed


Fastening cable in tower
With the large components installed, work on support infrastructure such as wiring began
Cabling to tower
A large infrastructure project such as a wind turbine requires a great deal of cabling to connect with the Battery Energy Storage System and NTPC's existing operational control system.
Four inverters are part of the BESS
Moving new transformer into place
A new transformer has been added to the electricity system to support the addition of the wind turbine and future renewables
Final positioning of new transformer


Wind turbine at night
Commissioning of the wind turbine began in August and continued into September 2023

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
Rotor upright

Shutdown of unit prior to overhaul
The Taltson hydro unit was officially taken offline in early May to allow the overhaul to get underway


Removal of old turbine
The first stages of the overhaul involve disassembly of older equipment and inspection and cleaning of internal components to ensure those not being replaced are in good working order 
Disassembly of old turbine pit


Bottom ring removal
New NGR being moved into position
The overhaul includes the installation of new equipment in addition to replacement of end-of-life components
Turbine shaft
Turbine shaft and turbine runner have been moved into the plant prior to installation


Turbine runner
Turbine runner and shaft
The turbine runner and shaft have been assembled
Turbine shaft
Painting of the turbine shaft is advancing
Removal of rigging
Heavy-duty rigging is necessary to hoist hydro unit components


Wicket gate
The installation of wicket gates began in early October. To determine the amount of power a hydroelectric dam can produce, wicket gates are used to manipulate the water flow as it approaches the generator. 
Water monitoring
There is ongoing water monitoring during the Taltson Overhaul to ensure we have a good understanding of the impact on fish and aquatic life as well as on water quality downstream of the hydro unit.
Many components are being replaced during the overhaul
There are many component parts that must be replaced as part of the overhaul
Cleaning up after fire swept through the facility in July
Fire swept through the Taltson site in late July. The site had already been evacuated and remained so for approximately seven weeks
