AI summary Nova Scotia Power provides a rate comparison table for large industrial and extra large industrial dispatchable customers, highlighting differences in fuel, non-fuel, and total charges, as well as demand and credit costs. The ELID Customer Charge is explained as a mechanism to recover costs related to dispatching PHP load and administering the ELID tariff.

10 Q ARE THE INTERRUPTIBLE SERVICE AS CONTAINED IN THE ELID AND THE LIIR 11 COMPARABLE? 12 A No. The LIRR interruptible service is limited to system reliability support. In contrast, 13 the ELID tariff provides interruption for economic an...

AI summary The ELID and LIIR interruptible services are not comparable. LIIR is limited to system reliability support, while ELID serves both economic and reliability purposes. ELID allows NS Power to interrupt PHP supply as a dispatch resource, whereas LIIR has limited interruption hours and is not used as a dispatch resource.

9 Q IS NS POWER'S PROPOSED ELID TARIFF RATE REASONABLE? 10 A. No. NS Power's proposed ELID capacity charge and interruptible credit are 11 imbalanced and overcharge PHP for its cost of providing service to PHP. The ELID 12 Tariff pricing s...

AI summary The answer states NS Power's proposed ELID tariff rate is unreasonable due to imbalanced capacity charges and interruptible credits that overcharge PHP. The ELID Tariff pricing requires modification to address these issues.

4 LINE TARIFF? 5 A NS Power has established specific forecast energy consumption levels for PHP to 6 calculate the proposed embedded costs, energy costing, and billing determinants for 7 the 2026-2027 test years. For the 2026 calendar year...

AI summary NS Power has forecasted PHP's energy consumption for 2026-2027, with a significant 2027 drop attributed to displacement by the Goose Harbour Lake Wind Farm's energy under a Power Purchase Agreement. Proposed energy charges apply to excess energy beyond a 'Subject Energy Amount,' with potential adjustments pending court proceedings over PHP's liability for the Maritime Link Federal Loan Guarantee.

3 TARIFF IN THIS PROCEEDING? 4 A We would recommend that the proposed ELID tariff reflect the current forecast energy 5 sales as provided in PHP's direct evidence. These forecasted energy sales figures 6 more accurately reflect the likely...

AI summary The proposed ELID tariff should align with PHP's forecast energy sales to ensure accurate cost allocations and revenue reflections of PHP's actual service costs. This approach establishes per-unit rates based on total system energy usage, improving financial accuracy.

11 Q PLEASE SUMMARIZE YOUR CONCLUSIONS AND RECOMMENDATIONS? 12 A In conclusion, Mr. Fitzhenry and Mr. Gorman recommend several modifications to Nova 13 Scotia Power Inc.'s proposed ELID Tariff to better align with cost-causation principles...

AI summary Mr. Fitzhenry and Mr. Gorman recommend modifying Nova Scotia Power Inc.'s ELID Tariff to align with cost-causation principles. Key changes include adjusting the capacity charge to reflect PHP's 8 MW firm demand, setting the interruptible credit to $13.107/kVA, applying a 1.0 revenue-to-cost ratio, and updating 2026/2027 energy sales forecasts post-Goose Harbour Lake Wind Farm integration.

AI summary PHP and NS Power communicate energy requirements and availability on various timeframes, aligning with the Active Demand Control Energy Supply Protocol. PHP has been under the ELIADC Tariff since 2020, providing system benefits through load flexibility, similar to a dispatchable power generation facility.

1 PHP has made its load available to be actively managed by NS Power Fuels, Energy 2 and Risk Management ("FERM") and the NSPSO according to the Active Demand 3 Control Energy Supply Protocol. DA and RT Schedules can range from longer peri...

AI summary PHP's load is actively managed by NS Power FERM and NSPSO under the Active Demand Control Energy Supply Protocol. PHP faces challenges due to unpredictable grid conditions and dispatch uncertainty, which affect operational planning and decisions. PHP has adapted its operations to accommodate the ELIADC tariff structure and provides grid reliability services through ADC.

15 Q. Does PHP agree with the proposed Above-the-Line Tariff as filed by NS 16 Power on December 29, 2025? 17 18 A. No. PHP has the following specific areas of concern with respect to the proposed 19 Above-the-Line Tariff: 20 21 (1) the us...

AI summary PHP disagrees with NS 16 Power's proposed Above-the-Line Tariff, citing four concerns: winter demand assumptions, interruptible load credit value, Revenue-to-Cost ratio exceeding 1.0, and outdated energy forecast assumptions. Technical evidence from Brubaker and Associates supports these objections.

22 Q. Please provide your understanding of how an Above-the-Line Tariff will 23 work in conjunction with the PHP Wind Project at Goose Harbour Lake. 24 25 A. An above-the-line tariff in conjunction with PHP Wind will provide PHP with 26 fi...

AI summary An Above-the-Line Tariff for the PHP Wind Project will provide PHP with fixed-cost energy, tracking mill consumption separately from wind production. Netting wind energy against mill consumption will determine PHP's final bill from NS Power, based on the tariff rate and additional cost/credit components.

6 Q. If the Board approves the proposed Above-the-Line Tariff as filed by NS 7 Power without addressing the areas of concern noted by PHP, how will PHP 8 proceed? 9 10 Unless PHP's areas of concern are addressed by the Board in a satisfact...

AI summary PHP will likely refuse to accept service under the ELID tariff if the Board approves the Above-the-Line Tariff without addressing PHP's concerns, necessitating the development of a below-the-line tariff with NS Power to meet the mill's needs.

15 Q. Aside from ADC and being priority interruptible, are there other aspects 16 of PHP's load flexibility that are not properly being captured in the ELID 17 tariff filing? 18 19 A. Yes. For example, on February 13, 2026 at approximately...

AI summary PHP's load flexibility during grid incidents (e.g., Maritime Link trip) is not fully captured in the ELID tariff, as it involved unplanned load reductions outside ADC and priority interruptible protocols. PHP's role in system reliability during such events highlights a gap in ancillary service value recognition within current tariff frameworks.
