Operations – Reliability Measure Definition
Unplanned Distribution Customer Outage Events
Unplanned outages affecting more than one customer that arise from activities such as third-party damage (line hits), operator error, facilities failure (e.g. station freeze-offs), and security issues. This metric aligns with the natural gas industry, which has a strong focus on the reliability of service. This is one of the key competitive advantages of natural gas as an energy supply. This metric is directly linked to this focus and will help to further highlight reliability of service to employees in the company.

Measure
Definition
Cumulative GHG Emissions Reduction Relative to 2019 Baseline (Tonnes CO 2 e) Customer GHG Savings (Tonnes CO 2 e/year) from Natural Gas Conservation Programs
This measure is a cumulative change in the amount of Scope 1 (direct emissions created on site) and Scope 2 (indirect emissions from electricity) greenhouse gas emissions from SaskEnergy operations, as compared to the baseline of emissions from 2019. This directly aligns to SaskEnergy’s corporate vision and reflects overall progress to the long-term target of 35 per cent reduction. This measure is determined based on emissions saved by customers in SaskEnergy’s residential and commercial equipment rebate programs. The emissions savings are modelled based on the difference between emissions ratings of new equipment and the regulated or commonly installed efficiency of the equipment replaced in programs, determined based on the age of the replaced equipment. The GHG savings consider both the gas and electric savings as a result of upgrading equipment.
