Clean Energy Facts

In 2016, customers of Hawaiian Electric, Maui Electric and Hawaii Electric Light Company were served by almost 991 megawatts of renewable energy resource capacity (including 543 megawatts of customer-sited rooftop solar). Total generation capacity available to meet our customers' electricity needs is approximately 3,015 megawatts.

These renewable energy sources resulted in 2,283 gigawatt-hours*, or 25.8 percent, of electric sales in 2016, as reported to the Hawaii Public Utilities Commission in our annual Renewable Energy Portfolio status report. This does not include energy savings from solar water heating or quantifiable energy efficiency. The 2016 total is an increase from 2,081 gigawatt hours or 23.2 percent of sales in 2015.

Tri-company electricity sales in 2016 totaled 8,845 gigawatt-hours.

* A gigawatt-hour is a unit of electrical energy equal to one thousand megawatt hours, one million kilowatt-hours, or one billion watt-hours. A 100-watt bulb burning for one hour uses 100 watt-hours of electricity.
