E1 Responses to Nova Scotia Energy Board (NSEB) Information Requests NON-CONFIDENTIAL 1 Request IR-16: 2 3 Regarding the Total Resource Cost (TRC) test, in Table 9 on page 40 of 149 in Appendix A of the 4 2023-2025 DSM application (M10473)...

AI summary E1 explains the difference in Total Resource Cost (TRC) between the 2023-2025 DSM Plan and the 2026 DSM Extension. The TRC for residential energy efficiency programs decreased from 1.4 to 0.9, primarily due to updated measure characterizations and cost assumptions in the 2026 plan. Host customer costs are excluded in the PAC test but included in the TRC, which affects the results.
