AI summary The 2026 DSM Extension RBIA analysis highlights that DSM programs lead to significant bill savings for participants, with Nova Scotian ratepayers expected to save $74 million over 16 years. Non-participants experience minimal rate increases, while higher participation reduces the number of customers facing rate hikes without bill savings. The analysis also notes that societal benefits like reduced emissions and local economic investment are not fully captured in the RBIA model.
