Nova Scotia Power Wind - Nova Scotia Power continues to examine opportunities for wind development in Nova Scotia, including examining opportunities for federal and provincial funding (e.g. Smart Renewables and Electrification Pathways Pro...

AI summary Nova Scotia Power is exploring wind development opportunities in Nova Scotia, including federal and provincial funding programs to reduce costs for customers. A project related to wind assets is included in ACE 2022 as part of the transition to 80% renewable electricity by 2030.

Critical Peak Pricing / Time Varying Pricing - Two-year Time Varying Pricing (TVP) pilots were approved by NSUARB effective November 1, 2021. - TVP pilots include Critical Peak Pricing (CPP) and Time-of-Use (TOU) tariffs available to Domes...

AI summary Two-year Time Varying Pricing (TVP) pilots, including Critical Peak Pricing (CPP) and Time-of-Use (TOU) tariffs, were approved by the NSUARB in November 2021, with over 1,000 customers participating. NS Power is calculating the Avoided Costs of DSM for scenarios 2.0C and 2.1C using the Difference in Revenue Requirement (DRR) methodology to support EfficiencyOne's DSM scenario development.

Evergreen IRP Process - The IRP Action Plan and Roadmap items that were identified in the 2020 IRP and advanced in the first year of Action Plan implementation continue to reflect appropriate planning activities for Nova Scotia Power at th...

AI summary Nova Scotia Power (NSP) acknowledges that the IRP Action Plan from the 2020 Integrated Resource Plan (IRP) remains relevant but recognizes the need for an Evergreen IRP update in 2022 due to significant changes in the planning environment, including new renewable energy targets and carbon reduction requirements.

1. Scope of Evergreen IRP 2022 Update – Assumptions AREA and the MEUs agree that changes have occurred since 2020 that warrant significant modeling updates. On Slide 2 of the 2022 Evergreen IRP Study Scope, NS Power states that the "evergr...

AI summary AREA and MEUs emphasize the need for updated assumptions in the Evergreen IRP 2022 study, requiring stakeholder input on GHG compliance modeling, Net Zero 2035 targets, firm import capacity, interconnection projects (TSR 411/412), battery storage, wind integration, and coal conversions. They stress transparency and timely information sharing to ensure assumptions reflect current data.

Attachment 2 NS Power Responses to Stakeholder Comments Theme Stakeholder Comment NS Power Response 1. Refresh input assumptions on an expedited schedule. We understand that finalizing some inputs may require more complex steps and be sens...

AI summary Stakeholders requested expedited updates to input assumptions and single-scenario modeling for the IRP. NS Power responded by incorporating early modeling insights into the evergreen IRP schedule, including draft assumptions and scenarios for stakeholder review.

Fast Acting Generation – CT IRP Action Plan Item 3c The 2020 IRP identified that new fast acting generation is required to support coal phase out and thermal unit retirements, integration of variable renewable generation, and load growth d...

AI summary The 2020 Integrated Resource Plan (IRP) identified the need for new fast acting generation to support coal phase out and system reliability with the integration of variable renewable energy. NS Power conducted a survey of available fast acting generation technologies, focusing on peaking power, ancillary services, and hydrogen compatibility.

The results of the LCOE andNPV RR analysisindicate the following: - Although Frame/Industrial GTs have a relative capital cost advantage to aeroderivative and RICE, disadvantages include higher heat rates and relatively lower flexibility....

AI summary The analysis of LCOE and NPV RR indicates that Frame/Industrial GTs have lower capital costs but higher heat rates and less flexibility compared to aeroderivative and RICE units. RICE units become more beneficial with higher capacity factors due to superior heat rates and turndown ratios. A combination of Aero GTs and RICE offers greater flexibility despite a small CAPEX premium.

NZ 2035-CURRENT POLICY AND TRENDS -ATLANTIC LOOP - ATLANTIC LOOP ADJUSTED TIMING Preliminary Scenario Metrics and Evaluation 26 Year NPVRR ($MM 2025$) $18,788 Key Input Assumptions and Observations 26 Year NPVRR with End Effects ($MM 2025$...

AI summary The document presents preliminary scenario metrics and evaluation for the Atlantic Loop project, including NPVRR values, CO emissions, and capacity expansion considerations. The analysis compares different planning scenarios, noting that delaying the Atlantic Loop's in-service date to 2035 still provides value despite higher NPVRR and emissions compared to previous plans.
