AI summary The document discusses the ADC Load Shifting Differential and Cause Code tracking issues in 2025. It includes financial details related to PHP and requests for information regarding incomplete Cause Code tracking and normalization of data for accurate year-over-year comparisons.

1 Request IR-1: 27 (a) The current process to determine the generation which served PHP involves running two 28 models in PortOps – one with the system as it ran in actuality ("With PHP"), and a second, 29 modeled system with PHP's load re...

AI summary The current process for determining the generation that served PHP involves running two models in PortOps: one with PHP's load and one without. Running this process multiple times for each Cause Code could create conflicts and invalidate results due to unit start and stop changes. PH Biomass is designated as a must-run unit and remains unaffected in this modeling process.

AI summary The text includes several requests related to forecasting protocols, load forecast divergence impacts, and reconciliation of ELIADC revenue with CBL energy charges and ADC/VOM adjustments. It also asks for FAM SWG presentation materials and a comparison of forecast errors across years.

NSPI has now confirmed: After investigation and internal discussions, NS Power has concluded that it is unable to develop an hourly cost and benefit analysis of all individual Cause Codes. Modeling and isolating the costs and benefits of i...

AI summary NSPI has confirmed it cannot develop an hourly cost and benefit analysis for individual Cause Codes due to limitations in the PortOps software, which leads to conflicting dispatch results and low precision tolerance. The Board is being asked to explain prior assessments, why implementation barriers were not raised earlier, and whether NSPI plans to seek relief or propose alternatives.

AI summary This document discusses the 2025 Annual Report on the ELIADC Tariff by Nova Scotia Power, Inc. It highlights that the actual cost to serve Port Hawkesbury Paper was below the forecasted cost, resulting in a positive ADC differential. The report also notes that PHP's load was 15% below its forecast due to challenges in forecasting energy demand in the paper market.

ere is no cause for concern. There were 95 total Cause Code 5 hours, or only 1.1% of all hours in the year, which as Bates White notes was the second lowest total of the six years of Tariff operation. The IG submits on page 2 that "the abs...

AI summary The text discusses the low occurrence of Cause Code 5 hours, the IG's concerns about load forecast revisions and interest on post-year-end balances, and stakeholder requests for transparency and improved reporting on the ELIADC Tariff. NS Power is responsible for providing updates and addressing audit recommendations.
