AI summary The Industrial Group submits observational comments on the ELIADC tariff, noting its expiration in 2026 and the need for NSPI/PHP to reapply for a new tariff or refreshed ELIADC if the ELID is not approved. Operational similarities between ELIADC and ELID may inform the Board's decision-making.
1. Actual Benefits to Other Customers Remain Below the Original Forecast It bears repeating that NSPI's 2019 ELIADC Tariff Application forecast annual benefits to other customers ranging from $6 to $13 million over the initial term, with a...
AI summary NSPI's 2019 ELIADC Tariff Application forecast annual benefits of $6–$13 million, but 2025 actual benefits were $4.4 million, 63% below the assumed load and 69% of the forecasted per-MWh benefit. Over six years, average annual benefits were $4.2 million, less than half the forecast. The IG argues this shortfall should be considered for the new ELID tariff in M12661.
4. PHP Load Revisions — Unlimited in Number and Frequency PHP's initial 2025 forecast totalled 811 GWh. There were revisions to PHP's load forecast throughout the year, with a final actual demand requirement of 691 GWh. This represents a r...
AI summary PHP's 2025 load forecast was revised downward by 15% (120 GWh) from 811 GWh to 691 GWh. NSPI states the ELIADC Tariff allows unlimited forecast revisions, while the IG argues this creates a structural advantage for PHP, recommending tariff design improvements to address the gap.
5. Recommendation XV-1 — NSPI Accepted, Then Determined it Was Not Feasible Recommendation XV-1 from the 2022-2023 FAM Audit required NSPI to develop a benefits calculation that takes into account the hourly benefits and costs of PHP load...
AI summary NSPI accepted Recommendation XV-1 from the 2022-2023 FAM Audit but later determined it was not feasible. The IG criticizes NSPI for not disclosing technical concerns about implementing hourly benefits calculations under the ELIADC Tariff, despite claiming to seek feasible approaches. The IG requests a specific alternative methodology and highlights inconsistencies in NSPI's response.
6. Recommendation XV-3 — Detailed Load Shifting Quantification Again Deferred In the 2022-2023 FAM Audit, NSPI accepted the recommendations of Bates White to improve the ELIADC annual reporting. In the ELIADC 2024 Annual Report decision, M...
AI summary The document discusses NSPI's repeated delays in providing detailed load shifting quantification as required by Recommendation XV-3, despite Board directives. The Board criticized NSPI for delaying tariff improvements, citing the 2025 Annual Report's omission of required details. NSPI attributed the 2025 delay to a cyber incident but provided no updates by March 2026. The IG urges the Board to impose a firm deadline for this analysis.
7. No Interest on the Balance Owed by PHP As a result of off-schedule charges exceeding the ADC benefit earned by PHP, PHP has a net balance owing of $149,304 for the 2025 tariff year. In response to IG IR-4, NSPI confirmed that these amou...
AI summary PHP owes $149,304 for the 2025 tariff year due to off-schedule charges exceeding ADC benefits. NSPI confirms no interest is charged on this balance until the Annual ELIADC Report is accepted. The IG notes this creates a cost-free financing period for PHP and recommends the Board address carrying costs for post-year-end balances.

Monthly Variability, Cost Recovery, and Reporting In its submission, the IG describes month-to-month variability between billed revenues and cost to serve, and requests NS Power "provide in the monthly reporting M-8, a month-bymonth compar...
AI summary The Industrial Group (IG) requests detailed monthly reporting from NS Power to compare billed revenues with the cost to serve, highlighting shortfalls and explaining accruals. NS Power explains that the ELIADC Tariff operates on an annual settlement basis, and monthly values are provisional and subject to reconciliation. The IG also suggests including annual benefits and costs in future reports for better performance assessment.
Cause Codes and Cost Sharing Variability In its submission, BW provided: The increase in Cause Code 5 hours from 2024 is concerning, if only because NSPI is only refunding 75% of the incremental costs of those deviations to its other custo...
AI summary The document discusses concerns around Cause Code 5 hours and cost-sharing under the ELIADC Tariff. It highlights that NSPI refunds only 75% of incremental costs from Cause Code 5 deviations to other customers, while PHP pays the full incremental cost. The Off-Schedule Charge is an incentive mechanism to encourage adherence to dispatch instructions and is fully recovered from PHP.
Conclusion The 2025 ELIADC Annual Report demonstrates that the ELIADC Tariff continues to operate in accordance with its approved design, enabling the integration of PHP's flexible load into system dispatch and providing measurable benefit...
AI summary The 2025 ELIADC Annual Report shows that the ELIADC Tariff functions as intended, integrating PHP's flexible load and providing benefits to other customers. NS Power submits that the report fulfills its purpose and that issues related to tariff design are outside its scope.
