Pillar one: Environment
From 2005 to 2019, we achieved a 61 per cent reduction in our emissions, which is attributable to refined emissions measurements and data, as well as operational efficiencies. Improving our operational efficiency
Leak Detection and Repair program
Emissions capturing on compressors
Emissions Data Management System
As part of our ongoing efforts to reduce methane emissions from above-ground infrastructure, we enhanced our operational Leak Detection and Repair program in 2019, which resulted in saving approximately 6,500 tonnes CO 2 e emissions in 2020. This is equivalent to taking 1,414 cars off the road.
In collaboration with industry partners, SaskEnergy installed emission-capturing devices on all new compressors, and retrofitted existing compressors, to reduce overall emissions from day-to-day operations.
SaskEnergy implemented a new Emissions Data Management System (EDMS) in 2020 to better understand and further reduce the overall environmental impact of our operations. The EDMS provides more accurate measures to improve reporting, documentation and prioritization of emissions management activities.
LOWER CARBON LINE HEATING
SaskEnergy operates hundreds of line heaters that preheat natural gas before its pressure is reduced so that gas can move from our transmission system onto our lower pressure distribution system. Keeping the gas temperature above freezing allows for the safe and reliable operation of pressure regulating stations. While older line heaters were simpler, they were relatively inefficient in terms of the amount of fuel they used to preheat the natural gas. Through SaskEnergy’s collaboration with a local manufacturing firm and the Saskatchewan Research Council, new line heaters were designed. Since initial field trials in 2003, these heaters are now widely used by utilities throughout Canada, as well as internationally, and are about 40 per cent more efficient than older heaters. SaskEnergy will continue to evaluate innovative technologies to further improve operational efficiency while reducing emissions.
