7、history of hardship,isolation,collaboration and perseverance.As people living and working on islands,were reminded daily about our intricate interdependence and the delicate balance we must maintain to survive,grow and provide for future generations.Climate change affects all life on Earth,but its i

8、mpact on island communities is especially severe,and requires an intense focus on resilience.While the Maui wildfires in 2023 have been among the most difficult challenges in our states history,we emerge from them hopeful in our communitys ability to collectively navigate the path ahead.HEI and our

9、family of companies,together with local communities,businesses,nonprofits and county,state and federal agencies,have made important progress to help our community respond to immense human,environmental,cultural and economic loss.As providers of critical infrastructure and services,HEI plays an essen

11、ross our businesses.Our board of directors,our customers,partners and suppliers,and all of our employees are vital players in our collective work to address these challenges.Our utility,Hawaiian Electric,contributes to this effort by enhancing the resilience of our energy system against the impacts

12、of climate change while advancing the decarbonization of Hawaiis electricity and ground transportation sectors,diversifying resources and supporting energy independence.In January 2024,the Public Utilities Commission approved Hawaiian Electrics$190 million Climate Adaptation Transmission and Distrib

14、ildfire Safety Strategy,initiated in 2019,will be updated continually to ensure that we are well-prepared to address elevated risks.A summary is included in this report.Renewable sources accounted for a full third of the electricity generated on the five islands served by Hawaiian Electric in 2023.S

15、everal major solar and storage projects came online to support grid stability and resilience,including one of the worlds most advanced battery systems,the Kapolei Energy Storage facility on Oahu,which provides 185 megawatts of total power capacity and 565-megawatt hours of energy.Thanks to these inv

16、estments,Hawaiian Electrics consolidated renewable portfolio standard(RPS)is now 33.3%.Although the company now expects to achieve a 70%reduction in GHG emissions from power generation later than the 2030 target date initially set in our Climate Change Action Plan,we remain on track to exceed Hawaii

17、s statutory goal of 40%RPS by 2030.Over time,these and other projects are designed to help strengthen resilience,reliability and cost stability for customers while bringing our state closer to its ambitious climate change mitigation goals.Our bank,American Savings Bank,is well positioned to support

18、our community with a strong capital position,excellent credit quality,lending capacity and ample liquidity.ASB acted quickly in the aftermath of the Maui wildfires to help impacted customers with a range of loan accommodations and other services.ASB donated approximately$135,000 to relief efforts an

66、e see Hawaii Pathways to Net Zero.Renewable Project Status BoardFor an updated look at our clean energy progress,please see Hawaiian Electrics Renewable Project Status Board.Greenhouse Gas(GHG)emissions inventoryThe following pages include a summary of our consolidated enterprise inventory and each

67、entitys historical GHG emissions inventory and components.Please see Appendix GHG Inventory Methodology for notes on methodologies and emissions factors used in developing the inventory.We have chosen to display both(a)a consolidated view of our inventory to show our combined footprint and(b)GHG inv

68、entories by major subsidiary to reflect categories and sources specific to each operating business,which is where the sources can be most impacted by company actions.With respect to the consolidated inventory,please note that since all of our companies operate in Hawaii and one of those companies is

69、 an electric utility,enterprise-wide emissions will not exactly equal a sum of the emissions from each entity.For example,for ASB and the HEI holding company,Scope 2 purchased electricity emissions largely represent electricity these entities purchase from our utility and are thus already reflected

70、in our utility Scope 1 and 3 generation emissions.Similarly,we have not included Pacific Current because its Scope 1 owned generation largely represents energy that it generates at its Hamakua Energy facility and sells to Hawaiian Electric for resale on Hawaii Island;thus it is counted in the utilit

71、ys Scope 3 purchased electricity for resale category.Pacific Currents employee-related Scope 3 emissions are also minimal,and were estimated as less than 70 MT CO2e in 2022.Climate Change Action PlanIn 2021,Hawaiian Electric set an aggressive goal to cut carbon emissions from power generation by 70%

72、by 2030,compared with 2005 levels.The emissions covered by this goal include stack emissions from generation owned by Hawaiian Electric and independent power producers(IPPs)who sell electricity to the utility.In addition,the utility has committed to achieving net zero carbon emissions from power gen

73、eration by 2045 or sooner.Since the time the 2030 goal was established,delays and cancellations in the commercial operation of new renewable third-party generation resources and higher costs as a result of supply chain disruptions and inflationary pressures,as well as federal policies related to sol

74、ar panel imports have slowed the pace of progress toward reducing GHG emissions.The downgrade of Hawaiian Electrics credit ratings after the Maui windstorm and wildfires is anticipated to be an additional impediment to completion of new renewable energy and storage projects.As a result of these chal

75、lenges,Hawaiian Electric expects the planned 70%reduction in carbon emissions to be achieved later than the original 2030 target date.However,the utility will continue to replace significant amounts of fossil fuel generation with renewable energy between now and 2030 and expect to meet or exceed the

76、 State of Hawaiis RPS goals.As noted above,the utilitys structure(vertically integrated with no access to wholesale electricity markets)means that its Scope 2 electricity use emissions are already reflected in its Scope 1 and 3 generation emissions.The utilitys generation emissions are also inclusiv

77、e of transmission and distribution(T&D)losses,reflecting the electricity that is consumed/lost in a T&D system.While utilities sometimes report independent power producer(IPP)T&D losses as Scope 2 emissions,the utility has categorized these IPP T&D losses as Scope 3 to remain consistent with its oth

78、er IPP-related public reporting.As of 2023,the utilitys preliminary GHG emissions from electric generation represented a 26%reduction from its Climate Change Action Plan 2005 baseline.The utility maintains a publicly available,online GHG emissions scorecard to report annual emissions from sources th

79、at supply electricity to our grids.Sustainability Data-26%Decrease in GHG emissions from electric generation from 2005 to 2023Note:All figures should be considered preliminary and subject to future verification.Detailed GHG methodology and assumptions are available on page 19.Biogenic CO2 emissions
