Our History and Timeline

The Hawaiian Electric Company and its subsidiaries provide electricity and services to 95 percent of the state's 1.4 million residents. The company is also one of the state's leading employers and a major contributor and supporter of community and educational programs.

The demand for power that has fueled the growth of the Hawaiian Islands has been met by Hawaiian Electric for well over a century. And as the next millennium unfolds, the company is committed to providing quality service and seeking clean local energy sources to power generations of Hawaii families and businesses to come.
