AI summary NS Power proposes maintaining the TVP Tariffs with suspended on-peak and critical peak event billing (Option A), arguing it preserves customer enrollment and minimizes disruption. The Consumer Advocate supports Option A but raises questions about winter demand management and potential revenue recovery from ratepayers.

SUMMARY: In general, customers in the TVP Pilot receive the same or better deal than they originally signed up for. Customers in the Comparable Standard rate could be disenfranchised because Pilot customers are getting a better deal withou...

AI summary The TVP Pilot provides customers with the same or better rates than their original contracts, potentially disadvantaging those on the Comparable Standard rate. Time of Use and Critical Peak Pricing rates are compared to the standard offer rate, with under or over collections having minimal impact. The TVP accounts for about 1.5% of NSPI's customer base, with estimated under collections of less than 0.03% of 2024 residential revenues.

AI summary The document raises two key considerations for Nova Scotia Power Inc. (NSPI): concerns about winter demand management without the usual demand signals from the TVP program, and whether NSPI would seek to recover lost revenue if winter billing is lower due to temporary solutions.

AI summary The SBA acknowledges NS Power's commitment to the TVP process but raises concerns about the evaluation of Option A rates and data collection for the TVP and CPP pilot programs. The SBA recommends that NS Power address these issues in an updated application and suggests a technical session with intervenors.

OVERVIEW On October 1, 2025, NS Power filed an application regarding its 2025/26 TVP tariffs. In this application, NS Power explained that the cyber security incident continues to impact its systems used to administer the TVP program and p...

AI summary On October 1, 2025, NS Power filed an application for modifications to its 2025/26 TVP tariffs due to a cyber security incident affecting its systems. The application proposed temporary changes to the Domestic, Small General, and General Critical Peak Pricing (CPP) and Time of Use (TOU) Tariffs.

• Option A: - o Maintain TVP Tariffs with suspended on-peak and critical peak event billing, instead billing TVP customers at their respective winter off-peak rate from November 1, 2025 to March 31, 2026; and - o Potentially resume schedul...

AI summary NS Power proposes maintaining TVP tariffs with suspended on-peak and critical peak event billing, billing customers at winter off-peak rates instead. Option B would fully pause the TVP program and revert to standard offer tariffs. NS Power recommends Option A due to administrative challenges and customer re-enrollment risks. The Nova Scotia Energy Board requested comments on the proposal, with Synapse responding on the appropriateness of charging TVP customers off-peak rates.

Small General CPP The situation for Small General and General Service customers on CPP tariffs is somewhat more challenging, as these customers would pay less than the SOR, but would not be subject to critical peak pricing events. As with...

AI summary The document discusses the challenges of implementing Critical Peak Pricing (CPP) for Small General and General Service customers, noting that they would pay less than the Standard Offer Rate (SOR) but not be subject to CPP events. Synapse acknowledges potential costs of adjusting rates to the SOR and supports NS Power's proposal to charge the off-peak rate, provided CPP events resume once system capabilities are restored.

TOU Rates NS Power states that the majority of TVP customers (67 percent) are enrolled in the Domestic TOU tariff.[6](#page-4-0) The Domestic TOU's off-peak rate is the same as the SOR, which supports NS Power's proposal to bill Domestic T...

AI summary NS Power proposes billing TOU customers at off-peak rates temporarily, with Synapse recommending approval. The proposal avoids re-enrollment and provides revenue, but Synapse suggests not guaranteeing off-peak rates for the full 2025/26 season, allowing for flexibility if systems are restored earlier.

CPP Rates NS Power proposes to bill all CPP customers at the off-peak rate. The off-peak rate for CPP customers is lower than the SOR. However, NS Power proposes to resume CPP events with 30 days' notice, should the capability be restored...

AI summary NS Power proposes billing CPP customers at the off-peak rate, with the possibility of resuming CPP events if system capabilities are restored. Synapse supports this proposal, noting potential additional costs if billing were done at the higher SOR. Synapse also suggests that NS Power does not need to provide 30 days' notice before resuming CPP events once systems are restored.

sociated with re-enrollment and rebuilding the participation base, particularly where the Domestic TOU winter off-peak rate proposed to apply for the five-month period is the same as the Domestic SOR. 5 Synapse recommends approval of the C...

AI summary The document discusses the proposed billing approach for TVP customers at off-peak winter rates, with Synapse recommending approval but suggesting it may not be necessary for the full 2025/26 season. The SBA emphasizes the need to balance objectives during a modified TVP Season, including maintaining participation, avoiding discriminatory rates, and minimizing costs to other rate payers. NS Power agrees and outlines Option A as the most feasible and least disruptive approach.

(4) Temporary Modifications and TVP Program Continuity As noted above, parties recognized the constraints leading NS Power to propose modifications for the 2025/26 Season. While the SBA and DOE suggested alternative approaches, such as mid...

AI summary The document discusses temporary modifications to the TVP Program for the 2025/26 Season, with NS Power proposing changes due to constraints. The SBA and DOE suggested alternatives, but these may complicate billing and customer experience. The CA endorsed Option A, emphasizing the importance of maintaining current TVP enrollment for long-term success.

Conclusion Stakeholder submissions demonstrate strong engagement and broad support for Option A, including endorsements from the CA and Synapse. While alternative suggestions – such as midseason CPP billing or adjusting TVP rates to match...

AI summary Stakeholders strongly support Option A for the TVP program, endorsed by the CA and Synapse. Alternative suggestions like midseason CPP billing or adjusting TVP rates to match the SOR were considered but rejected due to complexity and potential negative impacts. NS Power's approach is seen as a balanced solution under constrained circumstances.

Regulatory Counsel Theme Party Party Question or Comment NS Power Reply Impacts and Neutrality SBA d) Since this proposal follows directly from the Cyber Security breach, should any unwarranted tariff energy prices below standard rate equi...

AI summary The SBA questions whether unwarranted tariff energy prices below standard rates should be refunded to all ratepayers if NS Power is cited for imprudence or neglect under M12273. NS Power replies that the temporary application of off-peak rates may reduce revenue but will be partially offset by avoided costs and that the TVP program is designed to be revenue-neutral.

g) By not analytically deriving Option A rate parameters would this mean that: i. The proposed rates are discriminatory? ii. A load shape differential has not been established to determine if the lower cost recovery is justified on a cost...

AI summary The SBA questions whether not analytically deriving Option A rate parameters could lead to discriminatory rates, failure to establish load shape differentials, and lack of behavioral consumption change justification. NS Power responds that the temporary application of winter off-peak rates is not intended to drive behavior and reflects existing Board-approved rates from a four-year stakeholder engagement process.

Synapse (BCC) […] it may not be necessary to convey to customers that the off-peak rate will apply to all consumption through March 31, 2026. If NS Power's systems are restored earlier, NS Power could provide 30 days' notice that on-peak a...

AI summary Synapse recommends that NS Power notify TOU customers that off-peak rates will apply until further notice, rather than guaranteeing them for the 2025/26 TVP Season. The SBA and DOE seek clarity on the difference between adjusting TVP energy charges to match SOR and reverting TVP customers to SOR. NS Power's legacy CIS billing system makes implementing new rate options complex and administratively burdensome.
