11 Program cost recovery 12 EfficiencyOne tracks costs by rate class within each year. For each year of the 2020- 13 2022 DSM Plan, which was originally modelled by Navigant at the program level 14 (not by rate class), the planned investme...

AI summary EfficiencyOne tracks program costs by rate class annually. The 2020-2022 DSM Plan, originally modeled by Navigant at the program level, allocated investments to rate classes based on 2017 expenditure distributions. Annual DSM costs are converted to a $/kWh recovery component by dividing costs by with-DSM kWh sales per rate class.

4. Technical Resource Manual Most jurisdictions eventually develop a Technical Resource Manual (TRM) in which calculation methods, assumptions and (in some cases) default unitary values for energy savings and/or components used in the cons...

AI summary Efficiency Nova Scotia's electronic Technical Resource Manual (eTRM) is recognized as a useful tool for program purposes, aiding Econoler in independently verifying energy savings and demand-reduction measures. The text emphasizes the importance of maintaining independent checks to prevent circularity in eTRM usage and warns against streamlining monitoring and evaluation (M&V) to exclude actual project energy performance from financial return assessments.

Calculation Low income savings = (total savings) x (OP) x (10%)

AI summary The document presents a formula to calculate low-income savings: (total savings) multiplied by overall prevalence (OP) and a 10% factor. This method quantifies savings allocations for low-income households within a regulatory proceeding context.

Calculation Low income savings in county Z from undisclosed income group = (total savings in county Z from undisclosed income group) x (CP for county Z) Total low income savings = (tracked low income savings) + (total low income savings fr...

AI summary The document outlines a methodology for calculating low-income savings in County Z and total low-income savings across all counties. It uses a formula involving 'total savings in County Z from undisclosed income group' multiplied by 'CP for County Z,' then aggregates tracked low-income savings with savings from undisclosed income groups in all counties.

1.1.4 Estimate Energy Efficiency Potentials Navigant developed estimates of energy efficiency measure potentials in terms of Technical, Economic, and "Achievable" Potential. Note that the Energy Efficiency Achievable Potentials presented i...

AI summary Navigant estimated energy efficiency potentials using Technical, Economic, and Achievable categories, with Achievable Potential focusing on Efficiency Nova Scotia Corporation's DSM programs. Economic Potential used the TRC test, while the EERAM tool allowed the PAC test. The dual baseline approach calculated savings and costs based on remaining useful life of replaced equipment, distinguishing enhanced and regular savings periods.

NON-CONFIDENTIAL 1 Request IR-49: 2 3 Regarding "Per Unit Program Customer Cost ($)" reported in Column O of EfficiencyOne 4 2020-2022 DSM Resource Plan Filing, Appendix A Attachment 1, 5 6 a. Please describe how measure-level per-unit cus...

AI summary EfficiencyOne explains that per-unit customer costs for DSM measures are calculated using Navigant's PROCess model by subtracting incentives from gross costs. They note that costs vary over the 2020-2022 plan period due to changing incentives and do not retain formula-intact workpapers as calculations are embedded in the model.

o the question. Discussions with EfficiencyOne were held to gather additional insights for those cases where we did see and did not see documentation. In answering the question of whether there was an April 21, 2020 upward bias in the esti...

AI summary The EfficiencyOne Performance Alignment Study (April 21, 2020) examines cost estimation methods for DSM programs, including historical data use, external factors, and modeling by Navigant. Documentation shows incentive/admin costs were calculated for 2016-2018 and 2020-2022 plans, with NSUARB filings referenced.

AI summary EfficiencyOne overestimated customer participation in the Custom Retrofit program, leading to lower-than-planned costs. The 2015 Continuation Plan relied on historical data adjusted for future expectations rather than detailed measure-level modeling, which may reduce accuracy. NSUARB is involved in the regulatory review of these cost estimation methods.

o the type and nature of the resource cost. The depth of support will also be influenced by factors such as the significance of the cost and the availability and quality of the supporting information. In our review, we noted that Efficienc...

AI summary The review highlights concerns about EfficiencyOne's reliance on historical data for cost estimates, lack of supporting documentation for updates, and inconsistent documentation practices. It notes increased management involvement in recent years but criticizes insufficient rationale for adjustments to historical data used in 2020-2020 estimates.
