AI summary E1 set energy savings at 0.8% of NS Power's load, balancing affordability, cost-effectiveness, and sector allocation. This aligns with APEX's jurisdictional scan and the 2023-2026 DSM Plan. The Preferred Plan allocates 29%/71% to residential/BNI sectors, with 11% of residential savings directed to low-income programs, consistent with prior targets.

AI summary The section outlines the methodology for calculating energy efficiency participants in Nova Scotia, dividing them into tracked, untracked, and Residential Behaviour groups. Adjustments are made to avoid double-counting, and totals are capped per rate class annually.
7.2.3 RESIDENTIAL BEHAVIOUR PARTICIPATION - The Residential Behaviour program component applies the rate class weighted-average measure - life to estimate active participants; this is consistent with other tracked programs. For program- -...
AI summary The Residential Behaviour program uses a rate-class weighted-average measure life to estimate participants, ensuring accurate tracking without overestimation. A cross-participation factor prevents double-counting across tracked/untracked participation. Residential Behaviour is excluded from the 2027–2031 DSM Plan RBIA, focusing on post-delivery year participation decay aligned with energy savings.
