Consumer Advocate, EfficiencyOne, and industrial intervenors filed closing comments on NS Power's 2023 Evergreen IRP Action Plan and Roadmap, raising concerns about Atlantic Loop assumptions, DSM modeling limitations, and deferred capital projects
AI summary
- The Consumer Advocate's consultants (Wilson/Chernick, Exhibit N-4) criticized NS Power for stalling key clean-energy capital investments — including ECEI projects, dynamic line ratings, and the reliability tie — and urged the Board to speak clearly on the urgency of regional coordination, noting that NS Power's model assigns zero value to electricity exports over a future Atlantic Loop.
- Multiple intervenors (NRR, E1, Eastward Energy, PHP) questioned the reliability of Atlantic Loop modeling, citing a cost escalation from approximately $2.9 billion to $7.5 billion, NS Power's refusal to run a capital-cost sensitivity, ambiguous evidence on Hydro-Québec firm capacity availability, and NB Power's opposition to the project.
- EfficiencyOne (Exhibit 91371) identified that the 2019 DSM Potential Study — the basis for all IRP energy efficiency assumptions — is likely too conservative given higher-than-assumed electrification trajectories and the exclusion of emerging technology measures, and flagged that the counter-intuitive MMDSM result (only $7 million gross system savings from incremental DSM) was never addressed by NS Power.
- Intervenors broadly flagged that hybrid peak mitigation scenario costs were understated because NS Power excluded customer-side costs (insurance, maintenance, fuel, tank replacement for backup heating systems), and called for a multi-stakeholder study — potentially led by a third party — to capture full societal costs and GHG impacts.
- PHP and the Small Business Advocate emphasized procurement process risk, urging regular smaller procurements over large infrequent ones, all-source RFP best practices with stakeholder input, and timely completion of wind integration and synchronous condenser studies given the IRP's call for approximately 300 MW of new fast-acting generation by 2027.
