with weather, time of day, state of charge, or program design, and therefore may not coincide with periods of resource need. As a result, energy limited resources contribute less to resource adequacy. Effective Load Carrying Capability (EL...

AI summary The text discusses Effective Load Carrying Capability (ELCC), a method used in Nova Scotia to quantify the capacity contribution of energy-limited resources. ELCC is expressed as a percentage of a resource's installed capacity and declines with increased penetration of such resources. Energy+Environmental Economics (E3) conducted ELCC studies in 2019 and 2026 as part of the Integrated Resource Plan (IRP) process.

- Thermal conversions are reflected as firm capacity additions in the year they come into service: the Coal-to-Gas conversion (150 MW) represents the Point Tupper 2 conversion in 2028/2029, and Coal-to-HFO (459 MW) represents the Lingan un...

AI summary The document discusses two thermal conversion projects: Coal-to-Gas (150 MW) and Coal-to-HFO (459 MW), which are expected to be completed in 2028/2029 and involve the Point Tupper 2 and Lingan units 1, 3, and 4, respectively. The text raises questions about the start and end dates of these projects and the alternative resources that will replace their capacity and energy during the conversion process.

1 Request IR – 7 - 2 Refer to the 2026 Report Section 3 Existing Generation Resources, page 9, footnote 9. Please - 3 describe how much of the installed capacity in Table 2 is attributable to the Community Feed-In- - 4 Tariff (FIT) program...

AI summary The response to Request IR–7 indicates that 2.5 MW of the 27.6 MW of Biomass IPP capacity is attributable to the Community Feed-In-Tariff (FIT) program. Biogas FIT projects were aggregated with biomass projects due to their small volume. A list of all FIT projects is available in the 2025 Comfit Annual Report (M12687).

- NS states that it has contracted 100 MW of firm generation capacity from NB Power under a 10- - year agreement, with delivery beginning "as early as 2028." - a) Please describe the basis for the delivery timing assumption of Winter 2028/...

AI summary Nova Scotia has contracted 100 MW of firm generation capacity from NB Power under a 10-year agreement, with delivery starting as early as Winter 2028/2029. The proceeding seeks clarification on the basis for this timing assumption and the alternative plan if the import does not materialize.
