2 Q PLEASE DESCRIBE NS POWER'S PROPOSED ELID TARIFF FOR PHP. 3 A NS Power is requesting approval of an Extra Large Industrial Dispatchable ("ELID") 4 Tariff for PHP, to be available on, or before, January 1, 2027, following the termination...

AI summary NS Power proposes an ELID Tariff for PHP, replacing the expiring ELIADC Tariff. The ELID includes a Dispatchable Rider allowing NS Power to curtail PHP's load above 8 MW to reduce system costs and ensure reliability. PHP retains 8 MW firm demand rights, with NS Power prioritizing other customers during curtailments.

The ELID Energy Charge will apply to all delivered energy to PHP in excess of the subject Energy Amount deemed to have been provided, pursuant to the Power Sales Agreement issued under section 4 AA of the Electricity Act. 7 Energy credit w...

AI summary The ELID Energy Charge applies to excess energy delivered to PHP beyond a specified amount, with energy credits estimated annually. The ELID Demand Charge is based on a 'PHP demand determinant' set during the GRA process or other proceedings, with a stated demand price of $14.31/KVA-month in 2027. NS Power designates this as a 'fixed charge,' distinguishing it from other demand charges. The ELID Interruptible Service and Credit terms are similar to LIIR but with a 10% premium for PHP due to priority interruption.

15 Q HOW WILL NS POWER PROPOSE TO PASS ON THE BENEFITS OF THE DR AND 16 INTERRUPTIBLE SERVICE TO PHP? 17 A There will be two credits made to PHP cost of service. First, NS Power will provide a 18 billing determinant demand charge credit eq...

AI summary NS Power proposes passing benefits of DR and interruptible service to PHP via two credits: a demand charge credit (matching LIIR interruptible rates plus a 10% premium) and a power supply credit based on modeled savings from dispatching PHP load during high-cost periods. This reduces NS Power's supply costs, benefiting PHP while maintaining costs for ATL customers.

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.

2 Q. Please provide further details regarding PHP's operations during the time 3 of NS Power's winter month system coincident demand peaks over the past 4 number of years. 5 1 6 A. PHP cannot anticipate the exact timing of when a peak load...

AI summary PHP cannot predict NS Power's winter peak demand times and relies on NS Power/NSPSO for load dispatch. ELIADC's ADC mechanisms allow load reduction during peaks but were not designed for peak avoidance. PHP's historical load data is unsuitable for demand charges due to NSPSO's dispatch authority.

AI summary InterGroup supports aligning the IR credit mechanism with regulatory rate principles, emphasizes the need to separate interruptible and DR service loads, and approves IR credit for 2026-2027 based on the GRA Settlement Agreement. However, they oppose future IR credit without a mechanism to prevent double-counting DR and IR service values.

such, NSP proposes to examine the value of PHP's PI service in the next General Rate Application (GRA). - a) Given that LIIR customers who are not on Telemetry and Control ("T&C") can be, and in practice are physically interrupted ahead of...

AI summary NSP questions InterGroup about the practical benefits of PHP's Priority Interruptible designation, arguing that PHP is often dispatched down under DR during system constraints, making the PI status redundant and questioning the 10% credit in the 2026-2027 test years.

CA Response IR-5: a) Yes. - b) Yes, and this is supported by NSP statement that it remains to be determined whether Priority Interruptible service provides value to the system. - c) InterGroup notes that the 2026-2027 GRA SA stipulated tha...

AI summary The response confirms Priority Interruptible service's value remains undetermined. InterGroup references a 10% credit in the 2026-2027 GRA SA for priority interruptibility, noting load parameters were agreed upon for NSPI's Above-the-Line tariff in 2026-2027 test years.

IG Request IR-7: - c) Does InterGroup agree that if the review confirms that PHP is essentially never interruptible in practice, having already been optimally dispatched, then the appropriate outcome would be elimination rather than revisi...

AI summary InterGroup addresses questions about the IR credit, recommending elimination if PHP is non-interruptible, opposing reporting obligations for NSPI, and advocating Board approval of Operating Procedures affecting DR credit. It also highlights the complexity of the ELID Tariff requiring a Board review.

CA Response IR-7: - a) Yes, with allowance for future refinements, also subject to the Board approval. - b-c) InterGroup considers that the scope of the first-year review should include testing the performance of each approved ELID Tariff...

AI summary InterGroup agrees to future refinements and supports a first-year review of the ELID Tariff's performance against NSP's targets. They also endorse quarterly reporting on DR status by NSP, aligning with Mr. Bowman's recommendation for transparency in funding estimates.

PHP Request IR-2: Reference: Testimony, page 5: "InterGroup agrees with the concerns raised by NSP that including only the firm 8 MW of load would under-represent the degree to which PHP makes use of and benefits from the transmission syst...

AI summary InterGroup supports NSP's load parameters in the SA but notes that interruptible loads may underrepresent usage. They suggest this is a common issue and that alternative cost allocation methods could address it, though they find the current model reasonable.

PHP Request IR-4: Reference: Testimony, pages 6-7. "As confirmed by NSP in various responses to Information Requests from interveners, the billing demand, used in arriving at $13.107/kVA, equals the fixed 65 MW determinant, minus the 8 MW...

AI summary The text discusses the calculation of interruptible demand levels for PHP and LIIR customers, raising questions about metering practices and the appropriateness of using non-coincident PHP peaks and firm demand levels for calculating interruptible demand.

CA Response IR-4: a) and b) Please see the response to NSPI (SBA) IR-1(h) (Exhibit N-9), where NSP states as follows: [M](#page-3-1)12451, Exhibit N-9, page 10 and 11 of 29. Under the Large Industrial Tariff, billing demand is based on met...

AI summary NSP proposes using the cost of service assumption for billing purposes under the ELID Tariff, while InterGroup argues that PHP's interruptible demand should be calculated based on load characteristics from the Settlement Agreement and historical peak loads for future years.

AI summary InterGroup raises concerns about potential double-counting of benefits if the Dispatchable Rider and Interruptible Credit are paired, as they may both provide savings related to reduced load operations. The questions seek clarification on whether these benefits are distinct and whether the pairing poses a risk.

CA Response IR-6: - a) and b) The stated assertion that the two services are distinct and PHP is being compensated for two separate value streams (IR for planning relief (i.e the avoided cost of building new generation) and DR for operatio...

AI summary The document discusses the potential for duplicate compensation to PHP under two separate mechanisms — the Dispatchable Rider and the Interruptible Credit — due to overlapping load reductions. NSP confirmed that PHP has not been called for load reductions under the ELIADC Tariff and that during capacity scarcity, PHP load is already dispatched down, raising concerns about double-counting of credits.

Reference: N-20, Bates White Evidence, at p. 21, lines 2-6 notes a second concern: Our second concern is that the DR credit is built upon a shaky premise, namely, that PHP's load is sufficiently predictable as to allow for an after-the-fac...

AI summary Bates White Evidence raises concerns about the reliability of PHP's load forecasting for demand response (DR) credits, citing volatility, forecast errors (averaging xxxx/year, peaking at xxx GWh in 2023), and external variables (e.g., equipment performance, macroeconomic factors) that complicate accurate cost-based load (CBL) calculations. It questions NSPI's ability to model CBL without PHP's operational data and highlights risks of cost variability tied to forecast inaccuracies.

Response IR-5: - (a) Yes. - (b) FAM customers. - (c) There may be, but we have not developed one. Our recommendation is that any payments to PHP from FAM customers under the DR credit must be demonstrably tied to PHP deciding to shift load...

AI summary The response addresses demand response (DR) program design, emphasizing that payments to PHP from FAM customers must be tied to load-shifting due to energy prices. It compares the ELID Tariff's ex post demand control calculation to the ELIADC Tariff, noting differences in embedded cost rates and Goose Harbour Wind Farm output. Concerns about exogenous fuel cost fluctuations masking actual DR benefits are highlighted, referencing Bates White's audit.

The market for paper is somewhat seasonal with winter and summer months having generally less demand than spring and fall. - (a) Does Bates White agree that its finding that PHP would have higher demand in winter and summer months is incon...

for changes to its load profile that would have been made regardless of the ELID Tariff and its components. - (a) Is Bates White saying that the ELID, or the DR credit specifically, should not pay PHP for load variations that are done for...

AI summary The text raises questions about whether Bates White believes the ELID Tariff, particularly the DR credit, should not reimburse FAM customers for load variations unrelated to NSPI's pricing signals. It also inquires about potential modifications to the ELID Tariff and whether similar issues exist under the ELIADC structure.

Response IR-7: - (a) Yes. - (i) Not applicable. - (b) We have not put forth an alternative tariff mechanism. As we state in our evidence, we do not recommend that the Board approve the DR credit as proposed. We do explain that the DR credi...

AI summary The response to IR-7 states that an alternative tariff mechanism is not proposed, and the DR credit is deemed too vague and unverifiable. The ELIADC Tariff's variable rate differs from the proposed ELID Tariff's fixed rate, with concerns that exogenous factors may obscure load-shifting benefits. The DR credit requires revisions for verifiability.

Request IR-8: 2 Reference: N-20, Bates White Evidence, fourth concern, p.26, lines 3-11. According to NSPI, assuming that "for that [2025] period, if PHP load had been dispatched at 100 percent optimal," the DR credit would have been "appr...

AI summary NSPI estimates that the DR credit for the 2025 period would have been approximately $3.5 to $5.5 million if PHP load had been dispatched at 100% optimal, but discretionary adjustments reduced this amount. These adjustments were based on subjective factors and were not fully available due to a cyber incident.

Response IR-8: - (a) Yes, to the extent the question's reference to "Operating Procedures" is referring to IG-NSPI-IR-12 Attachment 1. - (b) Yes. (c) We have not proposed such a mechanism, nor is it our conclusion that a verification mecha...

AI summary The response confirms reference to a specific operating procedure attachment but denies proposing a verification mechanism for the DR Credit. It outlines requirements for any such mechanism, including full discovery of NSPI's model inputs and stakeholder testimony, with the onus on NSPI to demonstrate the reasonableness of the DR Credit calculation.

1 guardrails or reporting requirement? 2 (d) Under the current ELIADC tariff, load shifting savings are shared 75% to 3 other customers and 25% to PHP. Does Bates White agree that: 4 (i) The 75/25 benefit-sharing arrangement served as a 5...

AI summary The text raises questions about the ELIADC tariff's benefit-sharing arrangement, specifically whether the 75/25 split between other customers and PHP served as a buffer against overestimation of CBL and whether removing it would increase exposure for FAM customers. It also asks if Bates White objects to retaining a benefit-sharing approach in the ELID DR credit.

And p. 33, lines 10 - 18: - Q. Is there a potential scenario in which PHP has zero net load subject to the ELID Energy Charge? - A. Yes. As discussed above, the 653 GWh of output from Goose Harbour is a reasonable estimate of potential gen...

AI summary The text discusses a scenario where PHP (Potential for Higher Performance) could have zero net load under the ELID tariff, leading to no Energy Charge payments. It also raises questions about the true-up mechanism, its methodology, and whether PHP would remain connected to the NSPI system in this scenario.

And: We also recommend NSPI explain the methodology for tracking the costs of administering the ELID Tariff and how NSPI plans to ensure that 100% of the costs incurred above in administering the ELID Tariff are paid by PHP, including thos...

AI summary The text requests NSPI to explain the methodology for tracking the costs of administering the ELID Tariff and how PHP will cover these costs. It also seeks Bates White's opinion on quarterly reporting, the relationship between annual evaluation and true-up mechanisms, and the sequencing of these mechanisms in case of over-generation. Additionally, it asks whether the Board should impose specific reporting obligations.

AI summary The response to Request IR-5 discusses the theoretical net-avoided-cost figure as an upper bound for negotiated outcomes and confirms that the Board should pre-establish this cap as a condition of negotiation. The respondent also acknowledges the need for further calculation using NSPI's capacity cost data.

(b) Yes. (c) No, Ms. Whited is not currently able to calculate this value. The value depends on the demand-related costs for the Large Industrial (LI) class, the monthly billing determinants for each class, and the value of the interruptib...

AI summary The witness confirms that a calculation is not currently possible due to dependencies on demand-related costs for the Large Industrial class, monthly billing determinants, and the value of the interruptible credit provided to Public Health and Safety.

Q CAN YOU BRIEFLY SUMMARIZE THE RECOMMENDATIONS OF MR. BOWMAN? A Yes. Mr. Bowman makes five recommendations: - 1) The capacity value used in the Cost of Service ("COS") for PHP should be representative of PHP's average demand, rather than...

AI summary Mr. Bowman recommends adjusting PHP's capacity value in the Cost of Service based on its average demand rather than peak demand, and revising the DR credit allocation to prevent over-crediting PHP. NS Power argues that using average demand ignores PHP's efforts to reduce system peak demand and the need for capacity investment.

Q PLEASE EXPLAIN WHY MR BOWMAN'S PROPOSAL TO USE PHP'S AVERAGE DEMAND IN DEVELOPING A DEMAND ALLOCATOR IS DISCRIMINATORY . A. As discussed previously, the proposal to inflate PHP's contribution to the system 3-CP demand by substituting its...

AI summary The response argues that using PHP's average demand instead of its actual peak demand in the demand allocator proposal is discriminatory. It inflates PHP's contribution to system capacity, leading to an overallocation of production and transmission resources, which is not cost-based and unfairly advantages PHP.

Q IS MR BOWMAN'S PROPOSAL CONSISTENT WITH THE BOARD DIRECTIVES THAT COST OF SERVICE AND RATE DESIGN BE BASED ON NON-DISCRIMINATORY RATEMAKING PRINCIPLES? A No. While we are not attorneys, our understating is that the Board operates under a...

AI summary The response argues that Mr. Bowman's proposal is inconsistent with the non-discriminatory rate-making principles mandated by the Nova Scotia Public Utilities Act. It also rejects his recommendation to allocate demand costs to PHP based on its average demand, citing unfair cost distribution. Additionally, the proposal to provide NS Power with practical control of PHP load during constrained conditions is deemed unreasonable, as it disregards PHP's operational constraints.

Q HOW DO YOU RESPOND TO MR. BOWMAN'S THIRD RECOMMENDATION THAT THE 100% ALLOCATION OF DR SAVINGS RISKS OVER-CREDITING PHP FOR THE VALUE OF THE DR? A Mr. Bowman's recommendation to strip PHP of 100% of the calculated DR savings ignores the...

AI summary The response argues that allocating 100% of DR savings to PHP is justified due to its unique load flexibility and the structural changes in the ELID tariff. It also defends the Interruptible Rider credit, emphasizing its role in cost avoidance and system planning.

Q DO YOU AGREE WITH MR. BOWMAN THAT BECAUSE PHP MAY HAVE ALREADY BEEN DISPATCHED DOWN TO REDUCE LOAD UNDER THE DR THAT THEY SHOULD NOT RECEIVE AN IR CREDIT? No. Mr. Bowman's argument ignores the completely distinct benefits of the DR and t...

AI summary The response rejects Mr. Bowman's argument that PHP should not receive an IR credit because it already reduced load under the DR. It emphasizes that DR and IR provide distinct benefits: DR avoids high-cost energy hours, while IR improves system reliability during constraints. The two mechanisms are not conflated despite overlapping timing.

Q PLEASE REPLY TO MR. BOWMAN'S FIFTH RECOMMENDATION TO ELIMINATE THE 10% PRIORITY INTERRUPTIBILITY CREDIT. A Mr. Bowman's recommendation is without merit. PHP is the first customer to be interrupted on the system and thus acts as a resourc...

AI summary The response argues against eliminating the 10% priority interruptibility credit for PHP, stating that PHP's role as the first customer to be interrupted provides value to the grid and other customers. It emphasizes that the tiered interruptibility structure reduces system reliability risk and protects other entities from operational disruptions, making the 10% premium fair and balanced.

Q CAN YOU BRIEFLY SUMMARIZE THE RECOMMENDATIONS OF THE CA WITNESSES? A Yes. InterGroup recommends that the Board rejects all four of PHP's proposed tariff modifications, noting that parameters like the 65 MW 3-CP Demand Allocation and the...

AI summary InterGroup recommends rejecting PHP's proposed tariff modifications, approving the Interruptible Service component for specific test years, mandating a review of the ELID Tariff, evaluating the retention of DR savings, and requiring formal Board approval of PHP's operating procedures to ensure transparency and prevent cost shifting.

Q CAN YOU BRIEFLY SUMMARIZE THE RECOMMENDATIONS OF MS. WHITED? A Synapse witness Melissa Whited recommends that the Board approve the proposed ELID tariff, but subject it to specific, targeted modifications to achieve a more equitable allo...

AI summary Melissa Whited recommends approving the ELID tariff with modifications to ensure fair allocation of capacity costs and system benefits. She opposes PHP's proposal to assess demand charges solely on its 8 MW firm load and rejecting pricing interruptible credit at full marginal cost. Instead, she suggests negotiating a revised credit value to balance PHP's participation and benefit other customers.

AI summary Mr. Bowman's proposal is deemed analytically coherent with the Above-the-Line rate and NSPI's system demand. The Industrial Group raises concerns about the interaction between ELID and PHP's arrangements, dispatch rights under the Dispatchable Rider, benefit-sharing, and oversight of operational procedures.

2) DISPATCHABLE RIDER (DR): The DR credits PHP for shifting its load in response to marginal system costs. This is a substantial and unique benefit, particularly because it applies to approximately 800 GW.h of PHP consumption, even though...

AI summary The Dispatchable Rider (DR) provides PHP with credits for shifting load in response to system costs, including its own wind generation. While the benefit is acknowledged, concerns exist about insufficient control over PHP's dispatch and the potential for over-crediting. Recommendations include increasing system operator control and retaining benefit-sharing aspects of the ELIADC mechanism.

Recommendation #4 is to conclude there is likely little to no credit due under the IR. I take note of NSP's reply evidenc[e](#page-2-0)3 which indicates that PHP's load at 3 CP times will not necessarily be always dispatched down, and NSP...

AI summary The text discusses the determination of credit due under the Interruptible Rider (IR) for Peak Load Hours (PHP). It notes that PHP's load at 3 CP times may not always be dispatched down, and Nova Scotia Power (NSP) must account for this in generation planning. Credit would be based on expected material load after applying the Dispatchable Rider (DR).

4) PRIORITY IR: NSP also proposes a further 10% IR credit for "Priority" interruptibility, meaning PHP would be interrupted before other customers. I do not find this appropriate for three reasons: - 1. PHP is rarely interruptible in pract...

AI summary NSP proposes a 10% IR credit for 'Priority' interruptibility, interrupting PHP before other customers. However, this is criticized for being inappropriate due to PHP's low interruptibility, non-priority status compared to some LIIR customers, and lack of new value or interruptible load.

Recommendation #7 is to reject the PHP proposals. I also note issues raised by Synaps[e](#page-2-8)7 suggesting that some of the above ratemaking principles should be abandoned simply to arrive at a rate PHP will accept. That would be inco...

AI summary The text discusses concerns with the PHP proposals, highlighting issues with ratemaking principles, complexity of the DR mechanism, and potential discriminatory practices. It also references cost implications and differences in how demand is calculated for PHP compared to other customer classes.
