AI summary NS Power outlines generic timelines for the Evergreen IRP 2022 Update, with modeling stages set for Q2-Q4. AREA and MEUs request specific deadlines to ensure accountability, stakeholder engagement, and prevent delays from GRA or future capital applications.
3. Need for More Stakeholder Engagement in Future IRP Workshops NS Power initially circulated its IRP Action Plan Update to stakeholders on January 21, 2022. The stakeholder workshop did not occur until April 6, 2022, and unfortunately the...
AI summary NS Power's IRP workshop in April 2022 was criticized for limited stakeholder interaction, with NS Power primarily reiterating slides. The recommendation is for future workshops to assume stakeholders are familiar with materials and engage directly.
Reliability Tie Considerations We recommend that the base case for the IRP include significant schedule contingency for the Reliability Tie construction schedule. Normally, there would be some "known unknowns" contingency built into the pl...
AI summary The text emphasizes the need for significant schedule and cost contingency in the Integrated Resource Plan (IRP) for the Reliability Tie project, citing complexities in collaboration with New Brunswick Power and ongoing supply-chain constraints. It recommends robust planning to address potential delays and cost increases, treating on-time delivery as a sensitivity case.
Opportunities from Dispatch Improvements While the details of any procurement of IT systems recommended in Concentric's Dispatch Study are outside the scope of the IRP, the IRP planning team should coordinate with the market and operations...
AI summary The text highlights opportunities from improved dispatch systems, emphasizing coordination between IRP and operations teams to model IT system benefits. It stresses evaluating dispatch within the entire asset portfolio, not just individual generators, and suggests leveraging hydro units for AGC to reduce ancillary service needs. The Dispatch Study's findings on portfolio-wide assessments are referenced.
Timeline NS Power's proposed process and schedule for major revisions to the IRP are reasonable, and we have no suggested changes. However, the scope of recent regulatory, procurement, and other changes make it imperative that NS Power re-...
AI summary NS Power's proposed IRP revisions are deemed reasonable, but stakeholders urge re-evaluation of major projects due to regulatory and procurement changes. Concerns include independent evaluation of generation/storage resources and reliance on outdated 2020 IRP scenarios. An expedited process with stakeholder input and sensitivity analyses is recommended to address updated policies and ensure alignment with current planning environments.

AI summary E1 recommends that the 2022 Evergreen Study Scope focus on scenarios with NS Power's Net Zero 2035 emissions trajectory, which NS Power has included in its Evergreen process for scenario development.
Closing - E1 thanks NS Power for the opportunity to comment on the draft Evergreen IRP 2022 Scope and - Timeline and looks forward to continued work with NS Power and stakeholders. Date: April 14, 2022 Page 5 of 5 James A. MacDuff Direct +...
AI summary E1 thanks NS Power for the opportunity to comment on the draft Evergreen IRP 2022 Scope and Timeline and looks forward to continued collaboration with NS Power and stakeholders.
Re: 2022 Evergreen IRP Study Scope and Timeline On April 6, 2022, Nova Scotia Power Inc. ("NSPI") presented its IRP Action Plan Update and 2022 Evergreen IRP Study Proposed Scope and Timeline to stakeholders. Please accept the following br...
AI summary Port Hawkesbury Paper LP (PHP) supports Nova Scotia Power Inc.'s (NSPI) proposed 2022 Evergreen IRP Study updates but criticizes the lack of specific dates in the timeline. PHP argues that firm dates would improve stakeholder clarity and prevent delays, citing unresolved questions about GHG policies and import status.
N-4Evergreen IRP Action Plan & Roadmap Update
8 passages
MODELING APPROACH Capacity expansion and production cost optimization modeling developed least-cost portfolios for each scenario. The scenarios are compliant with current legislation, including the 2030 environmental policy targets of coal...
AI summary The modeling approach outlines scenarios for capacity expansion and production cost optimization, aligned with 2030 environmental targets (coal phase-out, 80% renewable electricity) and net-zero timelines (2035, 2050). Scenarios vary by electrification pace, resource strategy (including the Atlantic Loop), and sensitivities. Results include minimized total system costs (NPVRR), emissions, reserve margins, and generation profiles.
KEY FINDINGS Based on the common themes observed, the following are the key guiding principles to inform the Action Plan and Roadmap Items: - Variable renewable capacity additions are required to meet the 2030 targets. Up to 1500MW of addi...
AI summary The key findings emphasize the need for 1500MW of additional wind and 200MW of solar capacity by 2030, the critical role of the Reliability Tie and battery storage, the value of the Atlantic Loop for lower costs and emissions, and the importance of emerging technologies like SMRs. NS Power has updated its 2020 IRP Action Plan based on 2023 modeling.
Wind & Solar - There is a similar wind buildout for all scenarios between 2025 and 2030. For all scenarios modeled, a significant buildout of approximately 1500MW of new wind capacity (beyond the 600MW in service today) is added to the sys...
AI summary The document outlines wind and solar capacity expansions up to 2030, including 1500MW of new wind and 200MW of solar. It describes the bi-directional Atlantic Loop scenario involving Hydro Quebec, comparing expansion timelines between scenarios with and without the Loop.
Battery Storage - Battery storage is added to all scenarios with additions beginning as soon as 2025 in many scenarios. - At least 100MW of 4-hour battery storage is added by 2030 in the majority of scenarios. - Increased additions of batt...
AI summary Battery storage is projected to expand significantly by 2030, with at least 100MW of 4-hour capacity added in most scenarios. No Atlantic Loop scenarios show higher adoption rates. Storage provides energy arbitrage, curtailment reduction, and wind integration, though voltage/frequency support is not modeled in the IRP.
GENERATION MIX The evergreen IRP modeling results demonstrate that annual generation profiles are increasingly decarbonized through the planning horizon in line with environmental policy changes in 2030 and 2035 (please refer toFigure 4)....
AI summary The IRP modeling highlights a decarbonized generation mix by 2035, driven by wind energy and grid-scale batteries, with peaking gas turbines. Wind generation increases across scenarios, but curtailment ranges 10–45% due to integration constraints. No Atlantic Loop scenarios show higher emissions but achieve over 90% reduction from 2005 levels.
