AI summary The methodology calculates avoided transmission and distribution (T&D) costs by analyzing 10 years of NS Power project data. It identifies growth-related projects, adjusts costs for inflation, calculates average annual costs, applies a carrying charge, and determines historical load growth rates to estimate avoided T&D expenses.
Avoided Transmission Costs : = Carrying Costs for Transmission Growth Projects ($/yr) Annual Constrained System Growth (kW)
AI summary The document introduces a formula to calculate carrying costs for transmission growth projects, correlating annual constrained system growth in kilowatts to annual costs in dollars. This framework is central to analyzing avoided transmission costs within the regulatory proceeding.
Avoided Transmission Costs : = Carrying Costs for Transmission Growth Projects ($/yr) Annual System-Wide Growth (kW)
AI summary The text presents a formula relating annual system-wide growth in kW to carrying costs for transmission growth projects, highlighting the relationship between transmission expansion and associated financial impacts.
HISTORIC ANNUAL GROWTH - The historic annual growth rate for the 10-year period in question is a system-wide value. - Growth rate is determined from the Coincident Peak Demand with Future DSM Program Effects data published in the annual 10...
AI summary The historic annual growth rate for a 10-year period is calculated using system-wide data from the annual 10-Year System Outlook Report, specifically the 'Coincident Peak Demand with Future DSM Program Effects' metric based on System Peak (MW). This rate is applied to both Constrained System and System-Wide data to determine T&D growth in kW for the current year.
ANNUAL SYSTEM SNAPSHOT REPORT NS power performs a high-level Annual System Snapshot of its system based on the peak load hour of the year. The report is used to flag potential loading issues and to identify substations that may require mor...
AI summary NS Power's Annual System Snapshot Report identifies loading issues and substations needing study by analyzing transformer loads, feeder loads, and voltages during peak hours. Reports from 2016-2019 informed the Avoided T&D Costs methodology, with expanded tables in the Nov 16, 2020 spreadsheet.
AVOIDED T&D COSTS ASSUMPTIONS: INCLUSIONS System upgrade costs directly related to load growth that are included in Avoided T&D Cost Calculations: - Transmission capacity infrastructure upgrades - New substations (capacity/contingency capa...
AI summary The document outlines system upgrade costs directly tied to load growth that are included in Avoided T&D Cost calculations. These include transmission capacity upgrades, substation expansions, distribution feeders, voltage compensation devices, and reliability-driven infrastructure improvements related to load growth.
AVOIDED T&D COSTS ASSUMPTIONS: EXCLUSIONS System upgrade costs not directly related to load growth that are not avoidable and that are excluded in Avoided T&D Cost Calculations: - Transmission or distribution infrastructure replacements /...
AI summary The document outlines exclusions in Avoided T&D Cost Calculations, specifying that system upgrade costs unrelated to load growth (e.g., infrastructure replacements due to deterioration, reliability upgrades, and voltage conversions) are not considered avoidable. These exclusions clarify which capital expenditures are excluded from T&D cost savings assumptions.
