Real questions,
real answers
-
25 kV to 500 kV. Distribution work covers OH and UG up to 27.6 kV; substation EPC scopes range up to 245 kV and 240 kV.
-
Yes. Powerline technicians and HV electricians are trained and supervised against utility standards. Energized fault response is part of the 24/7 emergency response capability, with NFPA 70E and CSA Z462 compliance foundational.
-
Every scope runs to CSA C22.1 and C22.3 electrical codes with provincial amendments, IEEE, ANSI, IEC, and UL technical standards, and NERC-based reliability frameworks for transmission-connected work. Crews are COR-certified under provincial OH&S legislation. Our HV Canada business is ISO 9001 certified, and we work to each utility’s and client’s own construction and safety standards — engaging provincial regulators, and the CER on interprovincial projects, as required.
-
24 to 72 hours from 16+ regional offices across Canada and the U.S., with 700+ fleet vehicles available for emergency dispatch.
-
Yes. Long-term MSA structures are standard for utility customers; unit-price and time-and-materials structures are supported for distribution and emergency work.
