AFFORDABLE - • Minimize the present value of the long term costs of the power system - • Manage the magnitude and timing of electricity rate impacts

AI summary The document emphasizes minimizing long-term power system costs and managing the timing and magnitude of electricity rate impacts. These objectives focus on affordability and cost control strategies for the energy sector.

3.2 Maintaining Affordability As reflected in the Terms of Reference for this IRP, in addition to the traditional metric of minimization of cumulative present value of annual long-term revenue requirements over the 25 year planning horizon...

AI summary The 2020 Integrated Resource Plan (IRP) considers affordability by analyzing the magnitude and timing of electricity rate effects across different scenarios, such as Electrification, DSM, and DER. Affordability is influenced by system load levels and cost recovery mechanisms, with uncertainty increasing over the planning horizon. Nova Scotia Power provides 10-year rate impact analyses to address risks associated with long-term projections.

hich have no firm capacity value). Finally, the cost of the DER resources themselves is not included in these rate impact calculations but could be expected to add additional rate pressure if modeled. The slight rate increases in 2030 for...

AI summary The text discusses how retiring coal-fired plants by 2030 or 2040 increases rates due to the need to procure new capacity and energy. Early closure by 2030 may add rate pressure in the 2030s unless mitigated by electrification and higher fixed cost recovery from certain rate classes.

AI summary The text discusses the benefits of electrification on rates, the decommissioning of thermal units, the need for a comprehensive coal unit retirement plan, and the importance of wind and battery storage for carbon neutrality. It also mentions the need for an evergreen IRP process to refine findings and action plans.

integration will require careful and strategic consideration and coordination with other jurisdictions in the region to ensure Nova Scotia stakeholders receive the intended benefits. 3. Rate Impacts In its Updated Modeling Results and Draf...

AI summary The document discusses the importance of rate impacts and electrification scenarios in Nova Scotia’s long-term planning. It highlights the need for stable and predictable electricity rates, especially for industrial customers. NS Power’s new demand response service and the continued need for firm capacity resources are emphasized as key factors in achieving an environmentally and economically sustainable electricity future.

Further, the IRP provides the only opportunity for analysis of the long-term revenue requirement associated with the NS electricity system. This long-term view is critical in determining the lowest cost electricity system into the future,...

AI summary The Integrated Resource Plan (IRP) is crucial for analyzing the long-term revenue requirements of Nova Scotia's electricity system and determining the lowest cost electricity system. The UARB emphasized the importance of the IRP in utilizing both supply-side and demand-side resources to reliably serve Nova Scotia's electrical needs at the lowest long-term cost to ratepayers.

trategy and planning processes. The cost of electricity, as well as the presence of non-utility DER resources not otherwise captured in NPV calculations. stability and predictability of electricity rates, remain critical issues for all sta...

AI summary The document discusses the importance of stable and predictable electricity rates for industrial customers, particularly those competing globally. It also references the approval of an innovative demand response tariff by the Board and its incorporation into the Integrated Resource Plan (IRP).

AI summary The comment highlights an issue with the rate impact model in NS Power's Draft IRP Report, specifically the incorrect deduction of incremental fixed cost recovery from the revenue requirement, leading to potentially misleading rate estimates. The commenter recommends correcting this in the model and throughout the report.

AI summary The text critiques the methodology used in the Draft Report for rate analysis, pointing out several flaws, including inconsistent treatment of fixed costs, incorrect assumptions about cost recovery, and failure to consider transmission and distribution avoided costs. It also highlights that the Rate and Bill Impact Analysis (RBIA), developed through stakeholder consensus, has been used and refined since 2013.
