Roadmap Item 1 states: Advance engineering study work on coal to gas conversions at Trenton and Point Tupper Generating Stations. Monitor cost outputs of this work relative to IRP assumptions and update the balance of new and converted cap...

AI summary Roadmap Item 1 calls for advancing engineering studies on coal to gas conversions at Trenton and Point Tupper Generating Stations. The 2020 Integrated Resource Plan (IRP) suggests that coal to gas conversions may be a cost-effective source of dispatchable firm capacity, even at low capacity factors.

Coal Unit Conversions Since the conclusion of the 2020 IRP, NS Power has undertaken two parallel work streams examining the conversion of coal-fired units at Point Tupper and Trenton generating stations to natural gas fuel supply.

AI summary Since the 2020 Integrated Resource Plan, NS Power has been working on converting coal-fired units at Point Tupper and Trenton generating stations to natural gas.

Plant Conversion - Conceptual design and boiler studies have commenced and will continue into 2022. - Work in progress includes boiler circulation model development, outline of burner design and controls, plant pipe routing preliminary des...

AI summary The Plant Conversion section outlines ongoing activities related to the conceptual design and boiler studies, which are expected to continue into 2022. Current work includes the development of a boiler circulation model, outlining burner design and controls, and preliminary plant pipe routing and valve skid design.

Action Item 1a Throughout 2022,NS Power continued discussions with both New Brunswick and Newfoundland to explore opportunitiesfor incremental near-termfirmcapacity importsfrombothNewBrunswick andNewfoundland. Update on potential FirmImpor...

AI summary NS Power's attempts to secure near-term firm import capacity from New Brunswick and Newfoundland have faced significant obstacles due to transmission limits, committed exports, and capacity deficiencies. The 2020 IRP's assumptions and Nalcor's 2022 report indicate limited viability, leading NS Power to exclude these resources from near-term planning and the ongoing IRP update.
