AI summary NS Power will bill PHP for the cost to serve above monthly collections, including a $149,304 adjustment. The ELIADC Tariff aimed to encourage load shifting but only provided benefits in two of the six years from 2020 to 2025, with minimum payments prevailing otherwise.

AI summary NS Power claims to have met the Bates White recommendations from the 2022-2023 FAM Audit, but the SBA notes that it did not provide the promised update on load shifting benefits in March 2026.

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.

3. The Fixed Cost Minimum May Still Be Insufficient In the prior review, all intervenors and Board counsel consultant Bates White had recommended increasing the minimum fixed cost contribution above $4/MWh. The Board directed that the $4/M...

AI summary The Board increased the fixed cost minimum payment from $4/MWh to $5/MWh in 2026, but the IG argues this floor remains insufficient to protect ratepayers. Calculations show the $5/MWh rate would generate a $3.5 million annual floor, less than the $4.4 million 2025 fixed cost recovery benefit, requiring load shifting differentials to yield additional value.
