undersigned local governments recommend Duke further optimize charging behaviors and thus <br /> manage load and integrate more renewable energy sources on the grid through rate design that <br /> incentivizes off- peak charging , and explore the potential of Vehicle4o - Grid (V2G ) to tap the <br /> synergies between EV charging and the operational needs of the grid in ways that maximize the <br /> benefits for all customers . <br /> Similarly , the CPIRP should better forecast and incorporate the long -term load impacts of <br /> building code improvements and the growing trend toward beneficial electrification . Updating <br /> building codes in North Carolina is a cost effective way to reduce overall energy consumption , <br /> and thus lower the overall load on the grid . The North Carolina Building Code Council found that <br /> the commercial and residential provisions of the proposed 2024 NC Energy Conservation Code <br /> ( NCECC ) are expected to be cost effective . ? Adoption of the 2024 NCECC has the potential to <br /> realize annual energy savings of $ 0 . 23 per square foot for commercial buildings , and save the <br /> average NC household roughly $400 a year in utility bill savings . ' As widespread electrification <br /> adds loads , effective demand management will mitigate system costs and aid renewables <br /> integration within a power system that increasingly relies on variable renewable energy . <br /> Accordingly , the undersigned recommend that Duke proactively enable growth of building <br /> electrification and support the integration of renewable energy , thereby addressing grid and <br /> peak load impacts . Such consideration of beneficial electrification could have a positive impact <br /> on the cost of implementing the CPIRP . <br /> 4 . Energy efficiency and demand -side management ( DSM ) programs should be <br /> improved to help local governments and other ratepayers address affordability and <br /> climate concerns . <br /> Energy Efficiency ( EE ) and DSM programs are not only highly effective and cost-competitive <br /> grid resources , but can also tangibly benefit North Carolinians by lowering customer energy bills <br /> and decreasing energy burden . Many of the undersigned local governments participated in <br /> Duke ' s 2020 IRP docket proceedings and the 2022 Carbon Plan process , both as stakeholders <br /> in utility- led conversations , and as interveners and commenters in the dockets themselves . <br /> Local governments want to reinforce and expand upon those earlier comments in the context of <br /> the 2024 CPIRP proposed by Duke . <br /> The undersigned are concerned that Duke is not appropriately valuing the potential benefits of <br /> deeper investments in EE , especially in light of the large increase in system -wide electricity load <br /> that the utility forecasted in January . ' Implementing EE and DSM measures is a key lever that <br /> local governments can utilize to make progress towards their emissions targets , and local <br /> governments and other non -residential customers have significant opportunities to reduce <br /> electrical consumption and peak demand . Doing so provides both environmental and economic <br /> benefits to communities , including residents and businesses , and reduces system -wide <br /> generation needs . Greater EE and DSM programming should be evaluated and implemented as <br /> 7 Fiscal Note for 2024 Energy Conservation Code , NC Building Code Council .
