Hawaiian Electric is aligned with state policies and goals to decarbonize the ground transportation sector. EVs are an integral part of Hawaii’s clean energy future as more renewable energy is added to our electric grids.

For additional information on our efforts, please visit our Electric Vehicles page.

Fleet Electrification Scorecard

In August of 2020, the company pledged that by 2035 every passenger car, SUV, light pickup and minivan in Hawaiian Electric’s fleet will be a plug-in electric. Hawaiian Electric’s pledge is part of a nationwide collaborative commitment to electrify transportation by many member companies of the Edison Electric Institute, a national organization of investor-owned utilities. The company tracks the total number of its passenger EV miles driven as a percentage of their total passenger vehicle fleet miles driven and targets an annual increase of 10% in EV miles driven as a share of total passenger vehicle miles driven.

Metric: Total number of the company’s passenger EV miles driven as a percentage of its total passenger vehicle fleet miles driven

EVs are defined as plug-in hybrid vehicles or battery electric vehicles

Target: 10% annual increase in EV miles as a share of total passenger vehicle miles

Reporting Frequency: Annual

Measured EV Load (Energy) Scorecard

This scorecard aims to provide a better understanding of EV charging needs by identifying the kWh load delivered to charge EVs measurable by the company.

Metric: Measurable energy (kWh) delivered to EV charging stations in approved EV tariffs by time period, to be expanded to include enrollment in any subsequently approved EV tariffs (e.g., EV-U, EV-F, E-Bus, EV-Maui, EV-J/P)

Historical data is provided based on the implementation of the following tariffs:

  • EV-F are commercial pilot rates that were approved by Decision and Order No. 31338 issued on July 1, 2013, in Transmittal No. 13-07. Historical data available from 2013. EV-F will be closed to new customers on Oahu, Hawaii Island, and Maui Island as of March 18, 2022 with the approval of the EV-J and EV-P rates, discussed further below. EV-F will remain open to new enrollees on the islands of Molokai and Lanai until the sunset date of the tariff in June 2023. Visit our Commercial Facility page.
  • EV-U rates applicable to Hawaiian Electric’s DC Fast Chargers that were approved by Decision and Order No. 31338 issued on July 1, 2013, in Transmittal No. 13-07. Historical data available from 2014 when the first DC fast charger began providing charging service. Visit our Fast Charger Rates page.
  • EV-MAUI are rates applicable to four locations on Maui that were approved by Decision and Order No. 36943 issued on January 10, 2020, in Docket No. 2018-0422. Historical data available from 2020. The locations are: Lahaina Aquatic Center, Queen Kaahumanu Shopping Center, Piilani Village Shopping Center, and Pukalani Terrace Shopping Center. Visit our Fast Charger Rates page
  • E-BUS J/P pilot rates were approved by Decision and Order No. 36220 issued on March 20, 2019, in Transmittal No. 18-06 (Non-Docketed) and are available to bus fleet customers. Historical data available from 2019. Visit our Electric Bus Facility page.
  • New EV-J and EV-P rates for commercial customers were approved by Decision and Order No. 38157 issued on December 30, 2021 in Docket No. 2020—0152. The pilot rates are effective from March 18, 2022 to March 17, 2027 for Oahu, Hawaii Island, and Maui Island. The company will incorporate data from EV-J and EV-P into this scorecard as the data becomes available. Visit our Commercial Facility page.

Reported in charts by individual tariff and on a consolidated basis (all tariffs). Data by island is provided in the historical data (in Excel format) that can be downloaded below.

Measured EV Load (Demand) Scorecard

As EV adoption increases in Hawaii, it will be important to ensure that EV charging does not result in additional peak period constraints. The information from this scorecard will provide a better understanding of the average daily load shape of EV charging and how much EV charging is being done during and outside peak demand hours, which will help inform resource and system planning, as well as the design of future EV and TOU tariffs.

Metric: Average demand (kW) attributable to measured EV charging in approved EV tariffs by hour, to be expanded to include any subsequently approved EV tariffs

Target: Annual decrease in proportion of average demand (kW) attributable to measurable EV charging during on peak hours

Reporting Frequency: Annual

Estimated EV Load Scorecard

This scorecard provides a “best guess” estimate of the total energy delivered to charge EVs that captures measured EV load of the company’s EV programs and unmeasurable electricity to EVs (outside of the Company’s EV programs) or charging that occurs at non-metered charging stations based on data reported by the Department of Business, Economic Development, and Tourism (DBEDT), and reported by island.

Metric: Estimated total EV load (kWh), measured by:

  • Number of registered light-duty EVs (passenger EVs as reported by DBEDT) and average vehicle miles traveled (specific to Oahu, Maui, and Hawaii island);
  • Average kWh/mile (expected to be approx. 0.31); and
  • Load (kWh) from e-Buses

Target: EV kWh sales forecasted in the Integrated Grid Planning (IGP) proceeding (in Docket No. 2018-0165) for the applicable year

Reporting Frequency: Annual

EV Count Scorecard

This scorecard compares the number of registered light-duty EVs (passenger EVs) by island as reported by the Department of Business, Economic Development, and Tourism (DBEDT), to the forecasted EV count in the Integrated Grid Planning proceeding (IGP). The information from this scorecard will provide a better understanding of the rate of light-duty EV adoption relative to the company’s forecast.

Metric: Total number of registered light duty EVs (passenger EVs as reported by DBEDT) by island1

Target: EV count as forecasted in the IGP proceeding for the applicable year

Reporting Frequency: Annual

Ride Share Fueling Hubs Reported Metric

This Metric focuses on accessibility of electrified transportation options for all customers, regardless of vehicle ownership. Based on common vernacular, the company understands that Transportation Network Companies (TNC) such as Uber and Lyft are considered “ride share.”

Metric: Number of shared fueling hubs for Ride Share Only (with stored energy capabilities)
