10、h urgency and collective action.We first launched our Wildfire Safety Strategy in 2019,and we recently updated it for 20252027.It reflects input from a wide range of community stakeholders and demonstrates our commitment to a“whole-of-society”approach.We continued to rapidly progress our wildfire mi

11、tigation efforts throughout the year.Operational changes,new technology and the Public Safety Power Shutoff program implemented in 2024 have led to substantial strides in reducing the risk of ignition from utility equipment.And we continue to execute our Wildfire Safety Strategy,implementing actions

12、 that are expected to reduce risk further by 2027.This work is essential to protecting Hawaiis people,ecosystems and infrastructure.We will continue to refine and adapt our strategy to meet the evolving needs of our communities while leading Hawaiis transition to a clean energy future.As we look to

13、the future,we know that the transition to a more sustainable Hawaii requires laulima collaboration at every level.We remain steadfast in our commitment to working with businesses,community leaders and policymakers to expand access to clean energy and foster community-centered solutions that support

14、the needs of the people of our state.Our journey is rooted in aloha for all who call these islands home,respect for our lands and integrity and humility in our leadership.Together,we are building a future that honors Hawaiis unique heritage while creating opportunities for generations to come.Thank

23、Strategy The full 179-page document outlining Hawaiian Electrics 2025-2027 Wildfire Safety Strategy is available here Hawaiian Electrics highest priority is the safety of our communities,customers and employees.To advance this commitment,Hawaiian Electric has developed an enhanced Wildfire Safety St

24、rategy(WSS)that builds upon our immediate actions in response to the August 2023 windstorm and wildfires and establishes a 3-year action plan for 2025-2027.The objective of the WSS is to identify and implement measures that can accomplish the greatest risk reduction while balancing affordability and

25、 reliability for our communities.The cost of the 2025-2027 plan is estimated at about$450 million,including$137 million budgeted for work in 2025.Some of the cost is already funded through existing programs,including a federal grant for grid resilience received in 2024.The company plans to continue

26、refinement of the program and the long-term cost and scope of work are subject to change.Hawaiian Electric invested approximately$120 million to make wildfire safety improvements in 2024,including:Hawaiian Electrics enhanced Wildfire Safety Strategy is founded on a four-pillar approach:Harden and re

54、otes on methodologies and emissions factors used in developing the inventory.We have chosen to display a consolidated view of our inventory to show our combined footprint across Hawaiian Electric and the HEI holding company.We have not included Pacific Current because its Scope 1 owned generation in

55、 2024 largely represents energy sold to Hawaiian Electric that was generated at the then-owned Hamakua Energy facility(sold in March 2025).These emissions are thus already reflected in Hawaiian Electrics Scope 3 purchased electricity for resale category.As the electricity used by our companies is ne

56、arly entirely generated by Hawaiian Electric(with the exception of Pacific Currents operations on Kauai),Scope 2 electricity use emissions are reflected in Scope 1 and 3 generation emissions.Climate Change Action PlanIn 2021,Hawaiian Electric set an aggressive goal to cut carbon emissions from power

57、generation by 70%by 2030,compared with 2005 levels.The emissions covered bythis goal include stack emissions from generation owned by Hawaiian Electric andindependent power producers(IPPs)who sell electricity to the utility.In addition,the utilityhas committed to achieving net zero carbon emissions

58、from power generation by 2045or sooner.Since the time the 2030 goal was established,delays and cancellations in the commercialoperation of new renewable third-party generation resources and higher costs as a resultof supply chain disruptions and inflationary pressures,as well as federal policies rel

59、ated tosolar panel imports,have slowed the pace of progress toward reducing GHG emissions.The downgrade of Hawaiian Electrics credit ratings after the 2023 Maui windstorm and wildfires is anticipated to be an additional impediment to completion of new renewable energy and storage projects.As a resul

60、t of these challenges,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 expects to me

61、et or exceed the State of Hawaiis RPS goals.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 inclusi

62、ve 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 ot

63、her IPP-related public reporting.As of 2024,the utilitys preliminary GHG emissions from electric generation represented a 27%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 t
