- not undertake a review of PHP's financial condition.[32](#page-6-1) In response to a data request, PHP chose not to - provide its annual financial statements and indicated that "[n]othing in the [ELID] Tariff proposed in the - Applicatio...

AI summary PHP has declined to provide its annual financial statements, asserting that the ELID Tariff and proposed modifications are not dependent on its financial circumstances.

Q. Please summarize your evidence with respect to NSPI's application. - A. Again, our evidence addresses only the Customer Charge, Energy Charge, Dispatchable Rider, - and treatment of Goose Harbour output. Regarding the Customer Charge, w...

AI summary The evidence recommends revising NSPI's proposed Customer Charge to $12,291.67/month with reconciliation for ELID Tariff costs, updating the COSS model for ELID Energy Charge accuracy, and rejecting the DR credit due to insufficient load-shifting safeguards. PHP's cost recovery and Goose Harbour output integration are emphasized.

Q. What is the specific value of the Customer Charge proposed for the ELID Tariff? - A. NSPI proposes a charge of $10,000 to apply for each month through the end of 2027. [37](#page-8-3) After - 2027, NSPI proposes that "the ELID Tariff Cu...

AI summary NSPI proposes a $10,000 monthly Customer Charge for the ELID Tariff until 2027, after which it will be determined through future General Rate Application proceedings.

NSPI then simply selected the "low" end of this estimated range, or $10,000/month. 2 Q. Did NSPI elaborate on why it used the low end of the Customer Charge range? - A. NSPI explained that "the internal processes required to support the EL...

AI summary NSPI selected the lower end of the estimated Customer Charge range at $10,000/month. When asked why, NSPI explained that internal processes supporting the ELID Tariff are under development.

Q. What is your recommendation regarding the proposed Customer Charge? - A. We recommend that NSPI file additional evidentiary support for its proposed Customer - Charge. Absent this, we recommend NSPI set the Customer Charge for 2026 and...

AI summary The recommendation suggests NSPI must provide additional evidence for the proposed Customer Charge. If not, set it at $12,291.67/month (midpoint of its estimate range) with reconciliation mechanisms ensuring PHP receives credits if actual ELID Tariff costs are below collections. NSPI must also explain cost-tracking methodologies for ELID Tariff administration.

III. Assessment of the Energy Charge - Q. Please summarize the ELID Energy Charge proposed in NSPI's application. - A. NSPI proposes an Energy Charge of 9.977 ¢/kWh in 2026 and 11.240 ¢/kWh in 2027. 52 - Q. How were the Energy Charge rates...

AI summary NSPI proposes ELID Energy Charges of 9.977 ¢/kWh (2026) and 11.240 ¢/kWh (2027), calculated via a cost-of-service study (COSS) that treats PHP as an ATL customer. The rates incorporate fixed costs and net PHP load after subtracting Goose Harbour output (507 GWh), reducing PHP's modeled load to 304 GWh. This lowers PHP's total payments but increases per-kWh charges due to fixed cost allocation.

Q. Do you have concerns regarding the way the Energy Charge was determined? - A. Yes. Most significantly, we conclude that the net PHP load used in deriving the ELID Energy - Charge is too high, and the resulting Energy Charge rates are co...

AI summary The respondent raises concerns that NSPI's calculation of the ELID Energy Charge is flawed, citing an overestimated PHP load and an underestimated Goose Harbour capacity, leading to an incorrect net load figure and thus undervalued Energy Charge rates.

Q. What is the effect of PHP net load being too low in the COSS? - A. In most direct terms, if PHP's net load in 2027 subject to the Energy Charge is 121 GWh rather - than 304 GWh, a 60% reduction, the revenue from PHP to NSPI would be low...

AI summary A lower PHP net load in the COSS reduces NSPI's revenue by ~$21M (60% reduction) and increases ELID Energy Charge rates due to fixed costs not scaling with energy use. This risks under-contributing to system costs, shifting burdens to other FAM customers. NSPI's application uses an inflated PHP net load, leading to undervalued Energy Charge rates.

the proposed Energy Charge? - A. No, not based on our reading of the proposed PHP Deferral account provisions. As specified in - the GRA Settlement, the PHP Deferral account is only intended to address effects from one or more of the - fol...

AI summary The proposed Energy Charge deferral is not applicable under the GRA Settlement, which limits the PHP Deferral account to specific scenarios. The text clarifies that distortions from PHP net load discrepancies with NSPI's ELID Energy Charge modeling are not covered by the deferral provisions.

Q. What do you recommend with respect to the ELID Energy Charge? - A. We recommend that the Board does not approve the ELID Energy Charge as proposed. We - recommend that NSPI be required to update the COSS model to better reflect likely P...

AI summary The recommendation is to reject the ELID Energy Charge as proposed, emphasizing the need to update the COSS model with accurate PHP net load estimates, including Goose Harbour's 168 MW capacity output. Modifying other ELID tariff components without this update risks under-recovery of costs from PHP, increasing FAM customer risk.

IV. Assessment of the Dispatchable Rider Credit

AI summary The document section evaluates the Dispatchable Rider Credit, focusing on its implications for rate structures and cost recovery mechanisms within Nova Scotia's energy regulatory framework. Key considerations include alignment with existing programs and impacts on stakeholder interests.

Q. Please describe the DR credit proposed by NSPI in the ELID Tariff. - A. NSPI asserts that the DR credit "will allow PHP to operate in a manner which reduces PHP's - individual cost of service, enables NS Power to manage PHP's load in re...

AI summary NSPI proposes a DR credit in the ELID Tariff to reduce PHP's cost of service, enable load management during system peaks, and compensate PHP for load flexibility. The credit structure aims to shield above-the-line customers from PHP's potential incremental cost impacts by incentivizing system-cost-reducing operations.

Q. Please explain NSPI's logic for including the DR credit as part of the ELID Tariff. - A. NSPI's logic is based on a "premise" that, as an above-the-line customer "with demand and - energy charges," PHP "would generally be incented to op...

AI summary NSPI argues that including the DR credit in the ELID Tariff aligns the interests of all above-the-line customers, including PHP, by addressing PHP's load flexibility. Without the Rider, PHP's levelized load profile could increase costs for all customers. The Rider ensures optimal system load profiles while managing PHP's demand and energy charges.

Q. Why will the DR credit be difficult (or impossible) for the Board and stakeholders to verify? - A. NSPI is afforded substantial discretion in determining the CBL. While NSPI is not purporting to - change the actual volume of PHP's load...

AI summary NSPI's discretion in levelizing PHP's load and lack of detailed data from PHP create verification challenges for the DR credit. NSPI's method is unclear, relying on limited examples and subjective factors. PHP's reluctance to share data (e.g., financial statements) and NSPI's lack of review exacerbate information asymmetry, undermining stakeholder confidence in the DR credit calculation.

Q. What is your fifth concern? A. Our fifth concern relates to NSPI's plan to use "forward replacement fuel costs"[100](#page-25-6) to determine the DR credit. While NSPI did not elaborate on the specific approach it would take, forward re...

AI summary The fifth concern is NSPI's use of 'forward replacement fuel costs' to determine DR credits, which may overstate system costs. NSPI has previously avoided this method in calculating load-shifting benefits under the ELIADC Tariff, citing concerns about overestimation.

Q. What is PHP's view of the DR credit? - A. Nowhere in the PHP Evidence did PHP criticize or raise concerns with the DR credit, as - proposed. (PHP raised concerns with other aspects of the ELID Tariff.) In response to data requests, PHP...

AI summary PHP did not criticize the proposed DR credit but raised concerns with other aspects of the ELID Tariff. PHP and its consultant believe the DR credit is 'appropriate.' NSPI's prior filings and tariff proposals are referenced in the context of ELIADC-related matters.
