ITEM 5: FEDERAL CLEAN ELECTRICITY REGULATIONS (CER) Track the ongoing development of the Federal Clean Electricity Regulations (CER). In particular, monitor for changes to carbon pricing policy or limitations on use of gas and oil-fired ge...

AI summary The document emphasizes tracking the Federal Clean Electricity Regulations (CER), focusing on potential changes to carbon pricing policies and restrictions on gas and oil-fired generation beyond those addressed in the evergreen Integrated Resource Plan (IRP).

1. No Atlantic Loop as Preferred Plan The lowest cost 26-year NPVRR (including distributed solar PV costs and end effects) base model run under the "current policy and trends" electrification assumptions for Nova Scotia is the No Atlantic...

AI summary The No Atlantic Loop scenario (CE1-E1-R2) is identified as the lowest-cost 26-year NPVRR model under current electrification assumptions, costing $130 million less than the Atlantic Loop base model. A hybrid peak mitigation variant reduces costs further by $2.33 billion, while a bi-directional flow sensitivity model shows even lower costs but lacks contractual commitments with Quebec. Synapse supports reassessing these scenarios with clearer cost data.

C. Regional Joint Dispatch In the Fuel Adjustment Mechanism Audit proceeding (M10416), the Consumer Advocate and Bates White agreed that NS Power should be encouraged by the Board to pursue regional joint dispatch with neighboring utilitie...

AI summary In the Fuel Adjustment Mechanism Audit proceeding (M10416), the Consumer Advocate and Bates White recommend NS Power pursue regional joint dispatch with neighboring utilities. Joint dispatch agreements pool generation for optimization, with options for a designated utility or independent administrator. The text contrasts this with Energy Imbalance Markets and Regional Transmission Operators (RTOs), noting joint dispatch typically avoids balancing authority consolidation.

AI summary The document discusses the need for further study on the impact of adding more variable renewable generation, particularly the potential need for synchronous condensers, and the implications of the Federal Clean Electricity Regulations on natural gas peaking capacity in Nova Scotia. PHP emphasizes the importance of a system-wide approach to assess these issues.

We also pointed to the commitment by Eastward Energy Inc. in its recently approved rate case setlement to engage at the provincial level on a study of this issue. The 2022 revision to the Public U�li�es Act has also charged Efficiency One...

AI summary The text discusses the need for a multi-sector study on strategic electrification, involving Eastward Energy Inc., NS Power, and Efficiency Nova Scotia. It highlights the 2022 revision to the Public Utilities Act and the role of Efficiency One in administering electrification programs. The study should investigate options for meeting heating and hot water needs and consider input from various stakeholders.
