16 4. 2026 DSM PROGRAMS
AI summary The document outlines the 2026 Demand-Side Management (DSM) Programs under regulatory review by the Nova Scotia Utility and Review Board (NSUARB). Key entities include the DSM Cost Recovery Rider (DCRR) and the Public Utilities Act (PUA), with involvement from the Independent Energy System Operator (IESO) and the Integrated Resource Plan (IRP).
1. ISSUE - The purpose of the avoided costs discussion with the Demand Side Management Advisory Group (DSMAG) - was to achieve the following deliverable as described in the DSMAG Terms of Reference: - " Developing a methodology and process...
AI summary The document discusses the need to update avoided costs methodology for DSM planning, noting unresolved issues from NS Power's 2024 work using the 2022 IRP Update. E1 uses these costs for the 2026 DSM Extension but emphasizes resolving remaining issues to ensure updated costs are incorporated into the 2027-2031 DSM Plan.
- From the time E1 filed its forward looking RBIA for the 2020-2022 DSM Resource Plan on February 28, 2019, a significant level of stakeholder engagement was undertaken through a RBIA Technical Session with the Demand Side Management Advis...
AI summary Stakeholder engagement led to revisions in E1's Rate and Bill Impact Analysis (RBIA) for the 2020-2022 DSM Resource Plan, including NS Power's assumption of cost allocation to align with their Cost-of-Service Study. Updates included avoided costs from the 2020 Integrated Resource Plan, incorporation of demand response programs, and partial year measure lives.
3. 2026 DSM EXTENSION RBIA RESULTS - The results in this section are for the 2026 DSM Extension. All impacts are calculated relative to a scenario - where no DSM is conducted in 2026. Results are summarized in Attachment 1, and have been p...
AI summary This section presents the 2026 DSM Extension RBIA results, comparing scenarios with and without DSM implementation. Impacts are calculated relative to a no-DSM baseline, with energy efficiency and demand response analyzed separately and combined. Attachments 1 and 2 summarize results, including rate and bill impacts by rate class, and model outputs.
4. GHG EMISSIONS BY SCENARIO NS Power's August 23, 2024 avoided costs deliverable provided annual GHG emissions for the scenarios CE1-E1-R2, Base DSM, No DSM ("No EE, No DR"), and No DR. E1 has plotted the annual CO 2 emissions intensity b...
AI summary NS Power's analysis of GHG emissions under various scenarios (CE1-E1-R2, Base DSM, No DSM, No DR) shows the No DSM scenario exceeds the 50g/kWh post-2035 carbon cap. E1 argues that the same constraints should apply to all scenarios for avoided costs to be meaningful, citing the 2022 IRP's 50g/kWh limit. Figures 2 and 5 illustrate emission trends and discrepancies.
5. COMPARISON OF 2021 TO 2024 AVOIDED COSTS 2 2022 Evergreen IRP Updated Assumptions – Revised January 2023. Slide 12. January 26, 2023. E1 assessed the differences in avoided costs between the previous 2021 avoided costs (developed from t...
AI summary E1 compared NS Power's 2021 and 2024 avoided costs, noting that 2024 includes an embedded carbon cost absent in 2021. Annual avoided costs, not levelized values, were used for DSM Plan modeling. Figures 3 and 4 illustrate comparisons, with adjustments for CPI and carbon inclusion.
6. EMBEDDED AVOIDED COST OF CARBON WITHIN AVOIDED COST OF ENERGY At the direction of the Nova Scotia Utility and Review Board (NSUARB), in 2024 E1 initiated a process led by Energy Futures Group (EFG) to assess and develop an optimal DSM c...
AI summary E1, under NSUARB direction, is developing a DSM methodology with EFG, aiming to file a BCA application in 2025. The BCA test includes GHG emissions' societal impacts, requiring subtraction of embedded carbon costs from avoided energy costs. NS Power's OBPS carbon tax is referenced as reflecting marginal carbon costs, influencing the embedded carbon price calculation.
Nevada Power's Energy Efficiency Potential Sierra Club, Nevada (November 2011 – June 2012) - Research on Nevada Power's Integrated Resource Plan (IRP) and development of alternative energy efficiency potential projections.
AI summary Sierra Club conducted research on Nevada Power's Integrated Resource Plan (IRP) and developed alternative energy efficiency potential projections from November 2011 to June 2012.
mbers joined by their consultants); and • On April 22, 2025, E1 hosted a DSMAG Technical Briefing for the 2026 DSM Extension." a. Please provide the dates of the one-on-one meetings and a list of the stakeholders who participated each meet...
AI summary The document requests details on DSMAG meetings and materials from a technical briefing. It references the NSUARB's directive to update avoided cost calculations for DSM planning, incorporating 2022 IRP data and climate goals. E1 integrated updated avoided costs, including embedded carbon costs, for the 2026 DSM Extension, though separate carbon inputs were not provided.
Supply Agreement – COSS and DSM Rider NSPI has filed an updated proposed Cost of Service Study (" COSS ") with the General Rate Application (" GRA ") for the test years of 2026-2027, with DSM to be allocated 100% to customers. In addition,...
AI summary NSPI has submitted an updated Cost of Service Study (COSS) and proposed DSM Rider amendments for 2026-2027, including spreading DSM true-up recovery over multiple years. The Industrial Group reviewed the Supply Agreement between E1 and NSPI, finding no required changes but requesting E1 to address potential discrepancies in its reply.
