At Juno Engineering, we applaud the Northwest Territories Power Corporation (NTPC) on the successful return to service of the Taltson Hydroelectric Facility following a comprehensive, multi-year overhaul. This milestone marks a critical step toward long-term energy sustainability in the Northwest Territories—and we’re proud to have played a part in its journey.
Originally commissioned in 1965, the Taltson Generating Station is a cornerstone of the region’s energy infrastructure. Located at Twin Gorges, it has provided reliable power to communities across the South Slave region for decades. Yet, as with any aging facility, modernization was essential to ensure continued performance, safety, and system integrity well into the future.
In 2020, Juno was engaged as part of the Taltson Hydroelectric Expansion Project, delivering detailed electrical inspections and non-destructive testing services. Working in partnership with GHD Consultants, our team developed and executed a customized Inspection and Testing Plan (ITP) designed to address the plant’s complex electrical systems.
Our mission was straightforward: to assess the condition of the facility’s critical electrical and mechanical infrastructure, support long-term operational reliability, and ensure compliance with evolving safety and performance standards. This work formed part of a broader modernization initiative aimed at extending the plant’s lifespan and future viability.
Juno led all electrical testing and inspection activities, delivering actionable recommendations to guide asset maintenance and lifecycle planning. Our work included technical supervision or execution of the following scope:
- Development of a comprehensive ITP aligned with industry and regulatory standards
- Transformer oil sampling and diagnostic testing, including Dissolved Gas Analysis (DGA)
- Megger testing of high-voltage cables, transformer windings, and switchgear
- Inspection and maintenance of the station’s protection and control systems
- Field investigations, system verification, and updated as-built documentation
- On-site team technical leadership and coordination with other contractors for site services and construction planning
Executing this work in a remote northern setting brought unique logistical challenges. From transporting equipment by float plane to managing multidisciplinary on-site crews, each step demanded careful coordination to ensure efficiency and minimize disruptions to station operations.
We’re proud to have collaborated with NTPC, GHD, and fellow project partners in support of the Taltson Hydroelectric Facility’s restoration. While our involvement came during the project’s earlier phases, it remains a meaningful contribution to a larger vision of reliable, sustainable energy for the North.
