AI summary The document explains that the RBIA does not require detailed annual cost data for rate base calculations, as it only assesses DSM-induced changes while keeping other costs constant. This avoids the need for a full rate case analysis, focusing instead on directional and relative rate/bill changes due to DSM programs.

3.1 Revenue Requirement p. p. 165
3.1 Revenue Requirement The annual revenue requirements under the "With DSM" scenario are kept consistent with the test year information from the preceding rate cases. The non-FAM costs in the years following the 2014 test year from the 20...

AI summary The document outlines revenue requirements for 'With DSM' and 'No DSM' scenarios, adjusting FAM and non-FAM costs with inflation and DSM impacts. Historic cost true-ups are excluded due to minimal rate effects, lack of COSS rigor, and complexity. E1 provides avoided fuel cost data for post-2022 adjustments.

AI summary Legislative amendments extended the Board-approved DSM Plan to 2026, requiring E1 to file 2026 performance targets. Incremental costs arose from developing the 2026 DSM Extension and the new 2027-2031 DSM Plan. The NSUARB directed E1 to develop a cost-effectiveness methodology, leading to unexpected costs not included in the original 2023-2025 Plan. Flow-through costs from regulators, advocates, and consultants increased due to legislative changes and BCA development.

AI summary Demand response (DR) enhances grid reliability and aligns with Nova Scotia's decarbonization goals, including phasing out coal by 2030 and achieving 80% renewable energy by 2030. DR reduces peak demand, supports system reliability during extreme weather, and mirrors best practices from California, New York, and Ontario. Continued investment in DR is critical for Nova Scotia's early-stage DR framework development and long-term market growth.

AI summary EfficiencyOne (E1) seeks approval to extend its 2023-2025 Demand Side Management (DSM) Plan to 2026 under amended Public Utilities Act provisions. The Industrial Group submits that while the legislative investment amount is fixed, the Board must still assess the plan's cost-effectiveness, savings targets, and spending allocation. E1 requests exemptions from Board directives requiring detailed cost-justifications and payback information for certain measures.

Energy and demand savings targets p. p. 0
Energy and demand savings targets E1 proposes the following targets to correlate to the 2026 spend: - (a) incremental annual net energy savings: 116 GWh. - (b) incremental annual net demand savings: 18.9 MW. - (c) total available capacity...

AI summary E1 proposes energy and demand savings targets for 2026, including 116 GWh annual net energy savings and 18.9 MW demand savings. The extended DSM Plan under the PUA revises targets for 2023-2026 to 528.7 GWh energy savings and 97.7 MW demand savings, with a total investment of $236.8 million over four years.

Program Design p. p. 0
Program Design The 2026 plan is largely an extension of the existing three-year plan which E1 states was developed based on concepts of equity, accessibility and transparency. The single change to the design objectives for 2026 was a reduc...

AI summary The 2026 plan extends E1's existing three-year program, adjusting the low-income inequity investment target to 15-20% (down from 21% in 2023-2025 but up from 8% earlier). E1 cites updated census data showing low-income Nova Scotians decreased from 17.2% to 14.9% as the rationale for this change, emphasizing equity, accessibility, and transparency.

Rate Class Expenditures p. pp. 0-1
Rate Class Expenditures Below are the planned rate class expenditures for 2026:[3](#page-1-2) 2 Exhibit E-1, Evidence, page 5, line 19-21. 3 Exhibit E-1, Evidence, page 6. Rate Class 2026 ($ million) Residential/Charitable (2,3,4) 33.9 Sma...

AI summary The document outlines 2026 rate class expenditures across residential, industrial, and municipal sectors, totaling $63.75 million. E1 used 2022-2024 data and addressed concerns raised by the Industrial Group per the Board's direction. Key allocations include $33.9M for residential/charitable and $17M for general demand.

Programs p. pp. 1-2
Programs There are no new programs contemplated under the 2026 DSM Extension Plan. The three residential energy efficiency programs are: (1) residential efficient product rebates; (2) existing residential; and (3) new residential (the new...

AI summary The 2026 DSM Extension Plan does not introduce new programs. Existing residential and BNI energy efficiency programs continue, with the new home construction component retired. Demand response programs are also proposed to continue.

Anticipated Results p. pp. 2-4
Anticipated Results E1 anticipates lower energy savings and lower demand savings in 2025 and 2026 compared to those achieved in 2023 and 2024, despite the notable increase in the budget. It attributes this to the following factors: - E1 ha...

AI summary E1 anticipates lower energy and demand savings in 2025-2026 despite increased budgets, citing expired LED rebates, exhausted Canada Greener Homes Grant funding, and lower demand response adoption. 2025 targets 128.7 GWh at $62M, while 2026 targets 116 GWh at $63.75M, with rising unit costs ($0.49/kWh in 2026 vs. $0.39/kWh in 2023). Residential and BNI energy savings contributions shift from 35%/65% to 51%/49%.

Cost Effectiveness Testing p. pp. 4-5
Cost Effectiveness Testing E1 states that at the portfolio level, cumulatively the programs exceed the threshold ratio of 1.0, with a ratio of 1.6. E1 asserts that this thereby satisfies the statutory requirement of "cost effective" under...

AI summary E1 argues that a portfolio-level cost-effectiveness ratio of 1.6 satisfies the PUA 's 'cost effective' requirement. The Industrial Group disputes this, asserting the PUA allows granular cost-effectiveness testing beyond the portfolio level to assess DSM plans' alignment with customer interests and NSPI's obligations. The Consumer Advocate's consultant emphasizes the need for detailed cost-effectiveness criteria, target markets, and evaluation methods in DSM planning.

Mid-Course Adjustments and True-Ups p. pp. 6-8
Mid-Course Adjustments and True-Ups The Industrial Group has been expressing concerns with respect to E1's so-called "mid-course adjustments" by which E1 retains the discretion to shuffle spending between programs and customer classes. Whe...

AI summary The Industrial Group criticizes E1's mid-course adjustments for allowing program spending shifts between customer classes without quantifying 'substantial changes' or providing advance notice, despite Board-imposed 25% variance limits and commitments. E1 acknowledges shortcomings but outlines strategies to address concerns, citing historical data reliance and future allocation plans.

Supply Agreement – COSS and DSM Rider p. p. 8
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.
