Hawaiian Electric Industries, Inc. (HEI) is the largest supplier of electricity in the U.S. state of Hawaii, supplying power to 95% of Hawaii's population through its electric utilities: Hawaiian Electric Company serving Oahu, Hawai'i Electric Light Company serving The Big Island, and Maui Electric Company serving Maui, Lanai and Molakai.
Hawaiian Electric Company (abbreviated HECO and pronounced HEE-coh), Hilo Electric Light Company (later renamed Hawai'i Electric Light Company, abbreviated HELCO and pronounced HEL-coh), and Maui Electric Company (abbreviated MECO and pronounced MEE-coh) employ more than 2,000 people. Approximately 20,000 Hawaii residents are shareholders of HECO’s parent company, Hawaiian Electric Industries.[2] The company is headquartered in Honolulu.
The island of Kauai is the only Hawaiian island not supplied by HEI. Instead, the consumer-owned Kauai Island Utility Cooperative manages that island's electricity.
