Hawaiian Electric Co. is 125 years old.

The electrical utility, which today serves 457,800 customers, was incorporated Oct. 13, 1891.

Now the Hawaiian Electric Cos. — Hawaiian Electric on Oahu, Maui Electric Co. and Hawaii Electric Light on the Big Island — provide electricity to 95 percent of residents in the state and employ 2,727 people.

HECO said it is planning “125 Acts of Aloha” over the next year to celebrate the anniversary.

“All of us at Hawaiian Electric have worked hard through all of these years to help make these islands a better place to live and raise our families,” Alan Oshima, Hawaiian Electric president and CEO, said in a statement. “It’s been that way for 125 years and will continue for generations to come.”

HECO said its 125 charitable contributions will support nonprofit and community organizations in areas of education, family and community support, and environmental stewardship. HECO began the campaign by donating $10,000 to Trust for Public Land, $10,000 to the Institute for Human Services and $5,000 to Sustainable Coastlines.

In 2014 and 2015 the company contributed $1.5 million to 200 nonprofit and community organizations, according to HECO.

Over the next 20 years, HECO will be transforming its business model to comply with state law, which requires 100 percent of the state’s electricity come from renewable energy resources by 2045.

“We are proud of our 125 years of service and are committed to Hawaii’s clean energy goals,” said Oshima. “We will honor our past and retain our values but are transforming to help our customers meet the challenges and opportunities provided by technology in renewable energy, at a reasonable cost.”
