AI summary NS Power seeks approval to amend the FAM Plan of Administration (POA) for the 2026-2027 GRA period, including aligning fuel costs with COSS, adding renewable program credits, and moving OM&G expenses to FAM. The NSEB requested clarification on language in the amendment, and NS Power referenced prior Board decisions and matter M11127.

3.3.1.1 Findings [90] NS Power's proposed increase in OM&G costs is significant. It represents a 20% increase in 2027 (18.3% in 2026) from the OM&G costs included in rates approved in the 2023-2024 GRA. The burden is on NS Power to show th...

AI summary NS Power's proposed 20% increase in OM&G costs for 2027 is partially justified by the Board, citing increased customer service demands, the 5-Year Reliability Plan, and new grid-scale battery installations to meet RES requirements. The Board emphasizes NS Power must prove all costs are just and reasonable.

AI summary The text discusses the potential financial implications of a credit rating downgrade for NS Power, including higher interest costs on bond issuances and financing for key projects. A downgrade could lead to increased costs for ratepayers, with estimates of up to $5 million annually and significant increases in financing costs for projects such as the Battery Energy Storage Project and the Wasoqonatl Transmission project.

AI summary Morrison Park highlighted that securitization of stranded FAM balances helped NSPI lower bond yields. NS Power's credit rating downgrade to BBB- in late 2022 has led to increased debt costs, with potential additional annual interest costs of $25 million or more. This includes higher rates on new debt, refinanced debt, and penalties on government-backed financing arrangements for renewable and transmission projects.

AI summary NS Power outlines its 2026-2027 capital investment plans to ensure safe electricity delivery, environmental compliance, and alignment with Renewable Electricity Standards. The proposed investments support the 5-Year Reliability Plan and growing customer demand. Rate base growth will depend on DDA securitization proceeds, with potential offsets if securitization fails.

he Department submits that, at least as early as 2016, NS Power knew that its coal assets must be retired by 2030 but did not take this into consideration when valuing its assets. The Department said: In the 2022 GRA, the Department submit...

AI summary The Department of Energy argues that NS Power failed to account for mandatory coal plant retirements by 2030 in asset valuations, leading to improper ratepayer cost allocation. Regulatory standards require impairment write-downs for probable early retirements, which NS Power allegedly ignored despite clear federal and provincial policies. The 2020 Integrated Resource Plan's 2040 phase-out target is also criticized as inconsistent with 2016 federal legislation.

AI summary NS Power proposed a Decarbonization Deferral Account (DDA) to recover undepreciated thermal asset costs and decommissioning expenses, citing regulatory changes like the 80% renewable generation target by 2030 and the EGCCRA. The settlement agreement supports the DDA to mitigate rate impacts, similar to the 2011 'black box' settlement.

AI summary Concentric argues that NS Power requires a 9.9% return on equity to attract investment for its energy transition, citing stable capital costs since the last GRA but long-term challenges like climate change. This recommendation, based on DCF and CAPM models with flotation cost adjustments, exceeds the settlement agreement's proposed ROE.

The plan supports the 5-Year Reliability Plan and growing customer demand. Rate base growth is expected, partially offset by DDA securitization if successful.

3.6.2 Maritime Link Capital Projects [371] NS Power has four Maritime Link transmission capital projects that, by Board Order, have historically been excluded from rate base. The original intent of these projects was primarily to facilitat...

AI summary NS Power seeks to include four Maritime Link transmission projects in its rate base, arguing benefits outweigh costs. The Board previously rejected inclusion but set a test requiring revenue from wheeling tariffs or economic value of surplus energy purchases to meet depreciation, financing, and operating costs. NS Power claims to meet this test using 'surplus energy' and 'bilateral sales' in its 2023-2024 GRA, supported by undertakings U-24 and U-25.
