The company has a goal of having the majority of vehicles in Hawaii be electric by 2045
Hawaiian Electric Industries, Inc. (HEI) is the largest electricity supplier in Hawaii, serving 95% of the state's population. The company has a goal of having the majority of vehicles in Hawaii be electric by 2045. This is in line with Hawaii's state goals to reduce greenhouse gas emissions by 50% below 2005 levels by 2030 and to achieve 100% renewable energy by 2045.
To achieve this, the Hawaii Department of Transportation (HDOT) and the Hawaii State Energy Office (HSEO) must work together to ensure sufficient EV charging infrastructure and develop plans to increase the state's electric charging capacity. As of 2018, electric vehicles (EVs) made up only 1% of all vehicles in Hawaii, but the state has seen an increase in the adoption of EVs, with about 5,000 rechargeable vehicles as of 2017.
Hawaiian Electric has filed a roadmap with the state, outlining how it plans to utilize growing EV adoption to lower system costs and bring more rooftop solar onto the grid. The company foresees $60 million in benefits to its customers over the next 27 years, including avoided gasoline and vehicle maintenance costs. On Oahu, the transition to electric vehicles could benefit the broader economy by more than $200 million.
Hawaiian Electric is not the only electric company in Hawaii, as Maui Electric Company, Hawai'i Electric Light Company, and Hawaii Energy also provide electricity to the state. However, as the largest supplier, Hawaiian Electric's efforts to boost EV adoption and support renewable energy sources will be crucial in helping Hawaii achieve its goal of 100% renewable energy by 2045.
