Topic:"Renewable Electricity Regulations" in M11307

October 17, 2023 Ms. Crystal Henwood Regulatory Affairs Officer/Clerk Nova Scotia Utility and Review Board 1601 Lower Water Street, 3rd Floor P.O. Box 1692, Unit "M" Halifax, NS B3J 3S3 Re: M11307 Evergreen IRP Reply Submission Dear Ms. He...

AI summary NS Power submitted an updated Evergreen IRP in August 2023, reflecting changes in environmental policy, load, and resource assumptions since the 2020 IRP. The update aligns with Nova Scotia's 2030 environmental targets and demonstrates the company's commitment to adapting its long-term electricity strategy in response to policy and market changes.

ecisions are common to all scenarios, and that these no-regrets decisions can set the direction for utility operations during the period when the problems with this IRP are resolved." [12](#page-11-0) NS Power notes the release of Nova Sco...

AI summary NS Power acknowledges the Province of Nova Scotia's 2030 Clean Power Plan and its alignment with the updated IRP Action Plan. It plans to file a plan with the Board by December 31, 2023, to meet 2030 decarbonization targets. NS Power also appreciates feedback on the Evergreen IRP Update and intends to continue improving future updates.

AI summary The text emphasizes the importance of correctly identifying capacity needs for Integrated Resource Plan (IRP) runs and discusses the need for clear standards when choosing energy storage solutions. It also highlights anticipated challenges from federal Clean Electricity Regulations and how customer behavior may evolve with decarbonization policies.

e designs and demand response programs. AMI enables widespread adoption of TOU rates, which are a good starting point for encouraging load to shift from on- to off-peak periods. However, TOU rates do not facilitate customer responsiveness...

AI summary The text discusses the importance of advanced metering infrastructure (AMI) in enabling time-of-use (TOU) rates and dynamic rate strategies to manage load shifts and support flexible electrification technologies. It highlights the need for cost-effective communication and interconnection requirements, and mentions Vehicle Grid Integration (VGI) as an early use case. The text also notes the potential of offering electric rates for all-electric customers using heat pumps, while cautioning against cost shifting.

AI summary Electric light-duty vehicles (LDVs) offer greater lifetime benefits than costs from the perspectives of drivers, utility rate payers, and the province. While driver costs include upfront vehicle costs and charging expenses, savings from avoided gasoline costs and rebates offset these. Utility ratepayer benefits exceed costs, suggesting that average utility rates could decrease with increased EV adoption.

4.3.2 Transit Bus BCA Results This study models transit busses as a representative heavy-duty vehicle (HDV), which is classified as a vehicle weighing 15 tonnes or more. 56 The net present value (NPV) of lifetime costs and benefits for an...

AI summary The cost-benefit analysis of electric transit buses in Nova Scotia shows net costs from the driver/owner and provincial perspectives due to high upfront and charging infrastructure costs. However, from the ratepayer perspective, benefits outweigh costs, leading to potential decreases in utility rates. Managed charging with VGI reduces annual charging bills by about $3,750, though benefits for ratepayers decrease slightly compared to unmanaged charging.

The emissions savings from light-duty vehicle electrification under each charge management scenario are shown in [Table 4-6.](#page-66-1) Table 4-6. Lifetime emissions savings per electrified transit bus, 2022 and 2030 CO2 Emissions Saving...

AI summary The table shows the CO2 emissions savings from electrifying transit buses under different charging scenarios in 2022 and 2030. Both unmanaged and managed scenarios (with TOU and VGI) result in significant emissions reductions compared to internal combustion engine buses.
