Planning Environment Updates Clean Electricity Regulations – NSP Engagement and Process Roadmap Item 5 - Since the development of the CER was brought forward by ECCC in the fall of 2022, Nova Scotia Power (NSP) has been engaged with ECCC a...

AI summary Nova Scotia Power (NSP) has engaged with Environment and Climate Change Canada (ECCC) and Electricity Canada since 2022 to assess the proposed Clean Electricity Regulations (CER) regulatory framework, sharing findings throughout the stakeholder engagement process.

Planning Environment Updates Components of the CER – Planned Units Roadmap Item 5 - Planned Units - o Planned thermal units (examples: fast acting combustion turbines) are new thermal units in which investments have been made and planning...

AI summary The document outlines exemptions for planned thermal units under the Clean Electricity Regulations (CER). These units, including fast-acting combustion turbines, are exempt from the AEL if they meet construction and commissioning milestones by 2025, 2027, and 2035, respectively, to support variable renewable energy integration.

Planning Environment Updates Clean Electricity Regulations – Impacts on NSP Long Term Strategy Roadmap Item 5 What does this mean for NSP and the Province? - The CER supports and is in alignment with Path to 2030 and the Integrated Resourc...

AI summary The Clean Electricity Regulations (CER) align with NSP's Path to 2030 and Integrated Resource Plan (IRP), allowing existing resource plans to remain compliant. NSP anticipates incremental system costs to meet CER targets, though no changes to the Path to 2030 plan are required. Flexibilities from NS Power's engagement with ECCC support alignment with Evergreen IRP resource plans.

NON-CONFIDENTIAL 1 Request IR-1: 32 emissions value of 500 kt in a year, the operator could dispatch more from the lower-cost 1 units as opposed to the higher-cost units, as long as the total generation from the pool did 2 not result in em...

AI summary The text discusses the emissions value of 500 kt in a year and how dispatching from lower-cost units can reduce system costs while meeting Clean Electricity Regulations (CER) targets. It also mentions the potential reduction in capital expenditures due to the avoidance of additional combustion turbine capacity and the alignment of pooling provisions with the resource plan. The text refers to planned thermal units and their role in enabling variable renewable generation integration.

the Path to 2030 report (2024 update), to that of the 2023 IRP. [Synapse comments, pp. 2 and 6-7] Such concerns were repeated in other submissions, particularly those of the Small Business Advocate: There are recent policy changes, such as...

AI summary The text highlights concerns about NS Power's IRP process, noting that recent policy changes like the Clean Electricity Regulations (CER) have not been evaluated in resource planning. NS Power has deferred updating CT price assumptions, citing NSIESO's responsibility for future generation procurement. The Small Business Advocate emphasizes the need for accurate Nova Scotia-specific cost estimates and rate impact analyses for the next IRP.

Request IR-7: - Refer to Exhibit N-1, 2025 Evergreen IRP, page 16 of 42, referring to the "proxy used in the Evergreen IRP." - a) Please provide a comparison of the constraint parameters used in the proxy with the final CER rules. - b) Wou...

AI summary Request IR-7 seeks a comparison of constraint parameters in the proxy used for the 2025 Evergreen IRP with the final Clean Electricity Regulations (CER) rules. It also asks whether differences between the proxy and CER rules would alter capacity expansion portfolios, requesting supporting analysis.

Request IR-8: Refer to Exhibit N-1, 2025 Evergreen IRP, page 16 of 42, which states that "The use of emitting generation beyond 2035, which was demonstrated to be part of the low-cost resource plans in the Evergreen IRP, continues to be pe...

AI summary Request IR-8 questions whether the Evergreen IRP's modeling constraints included emissions offset costs or compliance specifics under the Clean Electricity Regulations (CER). It seeks details on how these factors were represented in the 2025 plan's low-cost resource scenarios.

Request IR-9: Refer to Exhibit N-1, 2025 Evergreen IRP, page. 16 of 42, stating that "NSP anticipates incremental system costs associated with meeting the CER's targets compared to current policy." Please provide additional detail regardin...

AI summary NSP anticipates incremental system costs from meeting CER targets. The request seeks detailed analysis of cost drivers and quantification of these costs over time, referencing Exhibit N-1 from the 2025 Evergreen IRP.

5.RECOMMENDATIONS Synapse remains concerned that NSPI has stated in various documents that it expects to have 600 MW of CT capacity by 2030 but has not shown this as an outcome of the IRP or the IRP updates. Enough has changed since NSPI c...

AI summary Synapse expresses concern that NSPI's claim of 600 MW CT capacity by 2030 lacks IRP alignment. Recommendations emphasize updating the Evergreen IRP with new data, evaluating resource options, and carefully assessing CT capacity economics. Scenarios must consider Mersey rehabilitation costs and regional coordination with New Brunswick Power.

Critical need for NS Power - NSIESO collaboration on next IRP Under Bill 404, the Nova Scotia Independent Energy System Operator (NSIESO) will be the entity responsible for conducting the IRP going forward. However, based on the dynamic co...

AI summary The document highlights concerns over the transition of IRP responsibilities from NS Power to NSIESO under Bill 404, noting uncertainty in the process and a lack of analysis on policy impacts like the Clean Electricity Regulations (CER). NS Power has not initiated future IRP planning or conducted rate impact analyses, risking long-term customer harm. NSIESO requires NS Power's data and expertise for effective planning, with SBA urging proactive data sharing.

Upcoming capacity needs require action in near term The 2023 Evergreen IRP calls for near-term dispatchable capacity additions, with a need for new capacity resources by 2030. NS Power has indicated that it stopped activities related to co...

AI summary The 2023 Evergreen IRP highlights urgent near-term capacity needs by 2030, with NS Power halting CT development due to NSIESO's procurement responsibility. Concerns include no entity addressing capacity planning, discrepancies in required capacity numbers, and CER regulations' 2035 emissions limits impacting resource classification timelines.
