nvestment is beneficial for customers as a whole; while the RBIA looks more closely at the worst-case scenario (a non-participant in each rate class) to see how much higher their bills are due to DSM. From the time E1 filed the 2019 RBIA i...

AI summary The document outlines revisions to the Regulated Business Investment Application (RBIA) over multiple years, emphasizing stakeholder engagement, removal of cost allocation, and integration of avoided carbon costs and demand response. DSM program participants experience varying bill reductions, with the 2022 RBIA incorporating new factors for accurate rate impact analysis.

4.1 OVERALL RATE IMPACTS - DSM can lower rates by avoiding different types of electricity system costs (avoided energy, - capacity, transmission and distribution, and carbon costs). DSM may also increase rates, a result - of recovering pro...

AI summary Demand Side Management (DSM) can lower or increase electricity rates depending on avoided costs versus program expenses. The 2022 RBIA analysis shows average rate impacts ranging from +0.2% to +3.0% over 2011-2039, with lower impacts in 2022 compared to 2021 due to incorporated carbon costs. Post-2025, rate impacts are projected to range from -1.5% to +0.1%.

2022 Rate and Bill Impact Analysis 2022 Rate and Bill Impact Analysis Appendix C: Sensitivity Analysis A sensitivity analysis was performed to determine key output sensitivity to changes in avoided cost input values. The avoided cost value...

AI summary The 2022 Rate and Bill Impact Analysis Appendix C details a sensitivity analysis conducted by NS Power to assess the impact of varying avoided costs on unit revenues. Three scenarios—Base, High, and Low—were evaluated by adjusting avoided costs ±25% across capacity, energy, transmission, distribution, and carbon. Results were integrated into E1's RBIA model for further analysis.

Figure 3: Avoided Costs Sensitivity Analysis: Average Non-Participant Bill Impacts (2011 – 2039)

AI summary Figure 3 presents a sensitivity analysis of avoided costs on average non-participant electricity bills from 2011 to 2039. It evaluates impacts under different scenarios, focusing on demand-side management (DSM) and related programs, including carbon emission differences and energy rebate initiatives.

Appendix D: Assumptions

AI summary Appendix D outlines key assumptions for a Nova Scotia regulatory proceeding, referencing acronyms related to energy management, cost studies, and regulatory applications. It provides context for terms like DSM, COSS, and RBIA, which are central to the proceeding's analysis.

6 Avoided Costs - 7 Avoided costs are calculated at the system level using evaluated DSM savings and avoided cost - 8 rates in four categories: generation, transmission, distribution, and energy. In addition, avoided - 9 cost of carbon was...

AI summary Avoided costs are calculated system-wide using DSM savings and rates for generation, transmission, distribution, and energy. A With Carbon sensitivity analysis also incorporates avoided carbon costs.

Participant Comments Synapse noted three primary changes to the 2022 RBIA: the incorporation of the avoided costs of carbon; the inclusion of demand response activities; and the use of enhanced measure of life assumptions. Synapse consider...

AI summary Synapse highlights updates to the 2022 RBIA, including carbon cost incorporation and demand response, noting lower rate increases due to carbon savings. They recommend enhancing DSM modeling transparency and integrating green energy plans. The Consumer Advocate supports reducing RBIA frequency, citing limited impact on program design.

AI summary Synapse highlights three changes to the 2022 RBIA: carbon avoided costs, demand response inclusion, and improved life assumptions. They note lower rate increases due to carbon costs and recommend improving participation in high-rate classes. Synapse advocates for a no-DSM scenario, DSM integration with clean energy, and model transparency. The CA supports reducing RBIA frequency and finds the report useful for DSM spending evaluation.
