AI summary NSPI responded to NSUARB's IR-9 request regarding a withdrawn RBP wind project, stating that its capacity and energy would be added to the Green Choice Program, increasing the maximum nameplate capacity from 350 MW to 416 MW. NSPI cited the RBP's 1100 GWh energy target and project attrition considerations as justification.

AI summary The Rate Base Procurement (RBP) and Green Choice Program (GCP) RFPs both account for project attrition, with RBP targeting 1,650–2,000 GWh of renewable energy. The GCP RFP allows flexibility in portfolio size, considering a 10% attrition rate and potential project size variability. Installed capacity calculations for wind farms are provided based on energy targets.

AI summary NSPI confirms alignment between the 2024 10-Year System Outlook and Green Choice RFP timelines, with no anticipated delays in Commercial Operation Dates (COD). Project CODs depend on interconnection design and Network Upgrade requirements per NSUARB-approved Generator Interconnection Procedures (GIP). General connection timelines cannot be guaranteed due to GIP compliance requirements.

AI summary NS Power recommends pausing engagement with neighboring utilities until the NSIESO operates independently. The CA highlights a discrepancy between NS Power's Path to 2030 submission and its BESS project positioning, questioning whether merging ECEI and Section 4D projects into a single 150 MW application reduces anticipated energy storage capacity through 2029. NS Power awaits Board feedback on its August 2024 letter.
