3.1 Existing Generation Resources The Nova Scotia generation fleet comprises a diverse mix of thermal, renewable, and energy storage resources. Thermal units operate on coal, petroleum coke, light and heavy fuel oil, and natural gas; renew...
AI summary Nova Scotia's generation fleet includes thermal, renewable, and energy storage resources, with 100 MW of Battery Energy Storage Systems added in 2025. Resource adequacy depends on the type of resource, with thermal and hydro units providing more reliable capacity than energy-limited resources like wind, solar, and storage.

AI summary The document presents a table listing various generation resources in Nova Scotia, including their fuel types, owners, capacities, Effective Load Carrying Capability (ELCC), and firm capacities. It includes data on natural gas, wind, solar, biomass, hydro, and battery energy storage systems, as well as independent power producers and wholesale market participants.
3.2.5 Battery Energy Storage Systems The Government of Nova Scotia's Clean Power Plan calls for 300 to 400 MW of battery storage capacity to be added by 2030. In 2025, 100 MW of BESS was added to the Nova Scotia system (referenced in [Tabl...
AI summary The Clean Power Plan aims to add 300 to 400 MW of battery storage by 2030. In 2025, 100 MW of BESS was added, with 50 MW planned for 2026. IESO Nova Scotia has included 250 MW of BESS in the 10-Year Outlook Resource Plan and will continue studying optimal storage additions in the 2026 IRP.

AI summary The table presents a 10-Year System Outlook (10YSO) with load forecasts, system peak, required capacity, existing and new firm resources, retirements, and reserve margin percentages for various years from 2026/2027 to 2035/2036. It outlines the capacity additions and retirements, including wind, storage, and coal-to-gas conversions, along with the resulting reserve margins.
5.1.1 Interconnection Requirements IESO Nova Scotia sets performance and interconnection requirements for BESS, generation, and load connecting to the Nova Scotia transmission system. These performance and interconnection requirements will...
AI summary IESO Nova Scotia establishes interconnection requirements for BESS, generation, and load connecting to the transmission system. These requirements are being refined as technology advances and local experience grows. Inverter-based resources (IBRs) like solar and wind can be integrated, though they may require additional grid support mechanisms. The TSIR, last updated in February 2025, will be reviewed in 2026.
5.2.1 Generator and BESS Interconnection The Combined Transmission & Distribution (T&D) Advanced Stage Interconnection Request Queue[38](#page-23-1) provides the location and size of generating and BESS facilities seeking interconnection w...
AI summary The document outlines the status of generator and BESS interconnection requests in Nova Scotia, noting that 20 interconnection requests are associated with 18 projects expected to connect to the transmission system before 2030. These projects involve Transmission Provider's Interconnection Facilities (TPIF) and Network Upgrades (NU), though work related to these is not included in the report.
