Yukon Energy is a publicly owned electrical utility that operates as a business, at arm’s length from the Yukon government. They are the main generator and transmitter of electrical energy in Yukon and work with their parent company Yukon Development Corporation, to provide a sufficient supply of safe, reliable electricity and related energy services.

Yukon Energy was considering the replacement of some the diesel generators with either new diesel generators or natural gas engines fuelled by liquid natural gas (LNG). The LNG would be obtained from suppliers in British Columbia and/or Alberta. Four power systems are compared in this report, a diesel fueled system and three LNG supply options. The diesel fuel system is based on new diesel generators and the existing diesel fuel supply system. GHG and CAC emissions were reported.
