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
Components of the wind turbine were stored in Hay River before being transported by barge to Inuvik in the summer of 2022Turbine blade arrived in Hay River in November 2021.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.On Sunday, August 7, 2022 the first pole for the future distribution line from Inuvik Wind was installed The wind turbine will sit on this structural steel spider web frameThe wind turbine blades were transported by barge from Hay River to Inuvik in the summer of 2022 Installation of the structural steel spider frame that will support the wind turbine continued despite the arrival of winterFunding support from the Government of Canada is critical to adding the wind turbine to the generation supply in InuvikThe crane that will help erect the wind turbine tower and blades in already onsiteInstallation on the distribution line connecting the wind turbine to the rest of the local electricity system continued throughout the winter of 2022/23Construction of the access road to the Inuvik High Point Wind site continued throughout the winter of 2022/23 and into the springTremendous progress is being made on the roadways at the site, including the approach to the wind turbine padStarting on May 6, 2023, major components that had been in storage were transferred to the Inuvik Wind siteThe first part of the turbine shaft being lowered into place on the steel infrastructure base.The tower to support the turbine blades was erected in May 2023On May 29, the first turbine blade arrived onsiteThe tower is now ready for turbine blade installation
Taltson Refurbishment
New turbine shaft that will be installed during the Taltson overhaulNew turbine that will be installed during the Taltson overhaulThe 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. 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 overhaulAssembly of the rotor, a key component in a hydro unit, occurred in the first quarter of 2023-24Once assembled, the rotor was tilted upright to free up floor space for other work required during the overhaul
Sachs Harbour -- new diesel plant
Commissioning of a new diesel plant in Sachs Harbour began in early 2022Construction of the new plant continued throughout 2022The new plant has three high-efficiency generators.The new plant will replace an older plant that has reached its end of life.
Lutsel K'e -- new diesel plant
Construction of a new, high efficiency diesel plant in Lutsel K'e began in 2021Installation of equipment, including three new high-efficiency generators occurred in 2022An announcement that the new plant was open and powering the community was made on January 25, 2023.The Government of Canada contributed more than $8.7 million to the project through the Investing in Canada Infrastructure Program
Snare Forks Unit 1 Refurbishment
Unit 1 at Snare Forks was returned to service in October 2020 following an overhaul that was financially supported by the Government of Canada through the Investing in Canada Infrastructure Program
