Whitehorse Diesel-LNG Conversion
While the Yukon draws the bulk of its energy from renewable hydroelectric and wind power, the territory’s electrical grid required a backup source of power to meet consumer needs. Yukon Energy retained KGS to modernize the existing diesel system to meet peak demand and maintain territory-wide service for residents.
A new liquefied natural gas (LNG) fueled backup power generating station and associated infrastructure was constructed adjacent to Yukon Energy’s existing primary power generating station in Whitehorse, Yukon. Commissioned in 2015, the project site includes two modular LNG fueled reciprocating generators intended to replace Yukon Energy’s aging diesel generating equipment and to provide flexible and reliable backup power to supplement Yukon’s other power sources.
Project Highlights
- An LNG backup station was built with two modular reciprocating generators
- First use of LNG in Yukon
- Lower greenhouse gas emissions than the previous diesel system, long‑term ratepayer savings and improved reliability and peak support
Royal Canadian Mint Geothermal Process Cooling System
KGS Group partnered with the Royal Canadian Mint to design and oversee construction of a cutting-edge, open‑loop geothermal cooling system for a new coin‑making process – a first for the Mint. The system uses groundwater’s stable temperature to cool equipment, replacing energy‑intensive chillers and cooling towers, nearly eliminating greenhouse gas emissions associated with conventional cooling.
Cooling now relies on a single pump and as the water absorbs heat from the equipment, heat pumps capture that free energy to warm the building through space heaters and ventilation systems. The conditioned water is re‑injected to the underground source, providing thermal balance and long service life.
KGS delivered an integrated design, controls coordination and construction oversight to bring the system online safely, with minimal disruption to operations. While this project significantly reduced the Mint’s energy use, the success here is the reduced environmental impact it will have for years to come.
Project Highlights
- Open‑loop geothermal process cooling with groundwater source and reinjection
- Single‑pump cooling loop with heat pumps that recover waste heat for building heating
- Integrated space heaters, ventilation equipment and facility controls
- Reduced energy use and lower operating costs
- Cooling-related GHG emissions nearly eliminated
- Thermal balancing for longevity, reduced environmental impact and reliable year‑round operation
