, on behalf of its clients, stated that it had reviewed the proposed Terms of Reference and is generally satisfied with the wording and approach and 1 Exhibit N-4. January 17, 2020 D. Friis provided a few additional comments for considerat...

AI summary NS Power and Natural Forces discuss the Terms of Reference (TOR) for the Integrated Resource Plan (IRP). Natural Forces criticizes NS Power's focus on minimizing revenue requirements in IRP modeling, arguing that greenhouse gas emissions reduction should be a primary criterion. NS Power reaffirms using revenue requirements as the primary metric but acknowledges other considerations.

erbuild going forward, and instead fully utilizes any surplus capacity (above minimum needs) that exists, however small, since the surplus is already roughly 20 percent greater than NSPI’s peak load. 2.2. Pre-IRP In 2019, NSPI conducted th...

AI summary NSPI emphasizes utilizing surplus capacity above minimum needs, noting it exceeds peak load by 20%. Pre-IRP studies (2019) informed the 2020 IRP process, with NSPI differing from Synapse on emissions standards. NSPI plans to iterate PRM calculations for portfolios with significant resource mix changes, as outlined in the Pre-IRP Deliverables Report.

llars was used. The NPV computation corrects for the use of real currency by using a 4.42% real discount rate, a rough approximation based on the 6.62% nominal WACC and a 2% inflation rate. Synapse Energy Economics, Inc. Analysis of NSPI 2...

AI summary The analysis highlights how carbon value impacts NPVRR calculations in NSPI's 2020 IRP, showing that carbon benefits can offset cost differences between scenarios. For example, early wind development with lower costs and $250M in carbon savings could validate economics, while coal plant retirements yield $375M in CO2 reduction benefits. NPVRR differences between scenarios shrink when carbon value is included.

of additional wind power: 631 MW of new wind by 2025 (Scenario 2.1C low wind cost), or 600 MW of new wind by 2024 and 676 MW by 2025 (Scenario 2.1C low wind and low battery cost). This single set of sensitivities demonstrates the importanc...

AI summary The text emphasizes the importance of market-based wind costs in determining optimal wind energy deployment scenarios, with NSPI advocating for explicit cost inclusion in the Action Plan. It highlights that incorporating carbon emission reduction value can justify higher wind installation levels even at increased costs, altering the Integrated Resource Plan's assumptions.

3. IRP RESULTS - A central outcome of the 2020 IRP Processfor E1 is to provide clarity on the level of DSM investment - that results in the lowest revenue requirement for ratepayers. This outcome is aligned with the first - stated purpose...

AI summary The 2020 IRP emphasizes that Base DSM investment yields the lowest revenue requirement for ratepayers under current assumptions. However, Mid DSM may become more economical at higher carbon prices ($50+ per tonne). The Reference Plan (2.0C) was selected for its alignment with least-cost objectives, though risk factors could alter future DSM planning.

AI summary The text discusses the trade-off between imported power and battery storage in NS Power's 2020 IRP, recommending battery storage inclusion in procurement despite its small near-term share. It also highlights the need to evaluate greenhouse gas emissions in bid assessments.

AI summary The text highlights inadequate stakeholder consultation in the IRP process, limited economic variables in the IRP scope (e.g., clean-tech subsidies, economic development), and calls for better metrics to account for climate damage costs. It also suggests exploring premium/subsidized tariffs to address energy poverty and proposes a Universal Service program.

AI summary The letter highlights that while the Integrated Resource Planning (IRP) process was comprehensive, it had gaps in addressing rapid policy/technology changes, climate agenda, and supply risks. It notes the IRP did not evaluate full benefits of shifting energy needs to electricity, grid opportunities from battery adoption, or decarbonization policy benefits. Stakeholder engagement was notable, and the need for an evergreen plan with clarity on inclusion and expert input is emphasized.
