Hawaiian Electric Touts Renewable Energy Milestones

To mark Earth Day 2017, utility company Hawaiian Electric highlighted its progress in replacing fossil fuels with renewable energy and reducing greenhouse-gas (GHG) emissions. The company, including subsidiaries Maui Electric and Hawaii Electric Light, provides power to 95% of residents on five of Hawaii’s six main islands. Notably, Hawaiian Electric says it reached a milestone in 2016, when 26% of the electricity used by customers came from renewable energy – up from 23% the year before – and the company anticipates meeting the state’s ambitious renewable portfolio standard ahead of schedule.

Many of Hawaiian Electric’s clean energy goals are described in the Power Supply Improvement Plan it submitted to the Public Utilities Commission in December. The plan calls for reducing operations that use fossil fuels, doubling the number of private rooftop solar systems and aggressively seeking grid-scale renewable resources, among other goals.

Regionally in 2016, Hawaii Island customers’ use of renewable electricity passed the halfway mark for the first time: 54% of electricity came from renewables, compared with 49% in 2015. Maui County also reached a new high of 37%, up from 35% the year prior. On Oahu, 19% of electricity used by customers came from renewable resources, up from 17% the year before.

From 2008 to 2016,Hawaiian Electric’s use of oil in generators on Oahu fell to 6 million barrels from 7.8 million barrels. Across the company’s entire service territory, oil use fell to 8.5 million barrels from 10.7 million barrels – representing a 21% decrease.

In other emissions-reducing milestones, the number of registered plug-in electric vehicles (EVs) has broken the 5,000 mark in the state – making Hawaii second in the nation after California in EVs per capita, according to Hawaiian Electric.

Hawaiian Electric’s Power Supply Improvement Plan also forecasts exceeding the state’s renewable energy milestones of 30% in 2020, 40% in 2030, 70% in 2040 and 100% by 2045. Specifically, the utility’s forecasts for future milestones now include 48% by the end of 2020, 72% by the end of 2030 and 100% by the end of 2040 – five years ahead of the 2045 deadline.
