Improving efficiency through line heater upgrades As the pressure within our gas lines drop from high to low — such as when gas moves from our transmission system to the distribution system at town border or regulating stations — the temperature within the gas line also drops, which can lead to the creation of condensation. To avoid the formation of liquids that can freeze within our lines, we use line heaters to preheat the gas and keep it flowing. As line heater technology has improved, SaskEnergy has been replacing older conventional line heaters with new models, which are 20 to 30 per cent more efficient. During 2022-23, higher efficiency line heaters were installed at 10 of our stations, with additional upgrade projects scheduled for 2023-24. Reducing fugitive emissions through leak detection and repair Since our leak detection and repair (LDAR) program began in 2020, the incidence of leaks at our above-ground transmission and storage facilities has been significantly reduced. To contribute to our goal of reducing emissions from operations by 35 per cent by 2030, we are surveying our compressor stations and meter stations for leaks numerous times each year, and more than what is required through regulations. Infrared cameras and other detection tools are used to identify leaks, which are then repaired. More than 1,500 leaks have been identified and repaired since the inception of the LDAR program and in 2022-23, a 55 per cent year-over-year reduction in the average number of leaks per site was achieved.

A new line heater, which is up to 30 per cent more efficient than older line heaters, is hoisted for installation.

Optimizing our electricity use In 2022-23, SaskEnergy’s first large-scale solar project was constructed at our town border station in south Regina. The 176 solar panels installed at this site can generate nearly 80,000 watts, which is enough to power the station’s lighting and electric heat and offset its annual power consumption. Three additional solar systems will be installed at our offices and facilities in 2023-24 and, over the next seven years, several other facilities will be converted to generate solar power. In addition, for more than 10 years, SaskEnergy has been installing solar panels at our natural gas pressure reduction stations and compressor sites. In 2022-23, we installed 85-watt solar panels with seven-day battery capacity at an additional 40 sites. Approximately 400 sites throughout the province now include solar power and another 40 sites are targeted to have panels installed or upgraded throughout 2023-24. SaskEnergy has also incorporated LED lighting at many of our larger compressor sites and as lights need to be replaced at our offices and facilities, they are being converted to LEDs. Moving forward with regulatory requirements Evolving federal and provincial methane regulations will influence our emissions reduction priorities and projects related to the reduction of vent gas and leaks on our system. SaskEnergy will adjust capital project plans in our roadmap to 35 per cent by 2030 to comply with these regulatory requirements as we continue to identify and address emissions reduction opportunities related to renewable electricity and the optimization of our infrastructure and processes.
