Hawaiian Electric Industries
Hawaiian Electric Industries, Inc. is the largest supplier of electricity in the state of Hawaii, supplying power to 95% of Hawaii's population through its electric utilities: Hawaiian Electric Company, Inc., Hawai'i Electric Light Company, Inc. and Maui Electric Company, Limited. In addition, HEI owns a financial institution serving Hawaii, American Savings Bank.
HECO, HELCO, and MECO employ more than 2,000 people. Approximately 20,000 Hawaii residents are shareholders of HECO’s parent company, Hawaiian Electric Industries. The company is headquartered in Honolulu. The net income of the company reached 164 million dollars by the end of 2012 with a yearly revenue of 3.4 billion dollars.
The island of Kauai is the only island in the state not supplied by HEI. Instead, the consumer-owned Kauai Island Utility Cooperative manages that island's electricity.
History
Hawaiian Electric Company incorporated on October 13, 1891. Within about 16 years the utility had 2,500 customers on the island of Oahu. By 1914 HECO had started rural service to the windward side of the island and was marketing electric products like refrigerators and flat irons. By 1937 HECO broke ground on its second power plant, and transmission lines soon crisscrossed Oahu.War and statehood
During World War II HECO power plants, now linked to busy military bases, generated more than one million kilowatt hours of electricity each day.Hawaii became a state in 1959, and by then the entire island of Oahu was electrified. Massive power plants, some still in operation today, came online. HECO flipped the switch on a 116 MW plant in downtown Honolulu in 1954. The state's first reheat steam turbine generator went on line at Kahe on the west coast of Oahu. Today, Kahe is the state's largest plant with a total generating capacity of 650 MW.
Island expansion
HECO purchased Maui Electric Company in 1968. In 1970, HECO also acquired the Big Island's Hilo Electric Light Company. MECO had expansion plans of its own. In 1988, it acquired the Lanai City power plant on the island of Lana'i, and in 1989, Molokai Electric Company on the island of Moloka'i. Hawaiian Electric Industries, Inc. was created as a holding company for these various utilities in 1983.In 2013, HECO began working with Siemens to develop a self-healing grid in eastern Oahu and Waikiki that will ensure a reliable electrical supply.
On December 4, 2014, NextEra Energy tendered an offer to purchase HEI for $4.3 billion. The sale required approval by the Hawaii Public Utilities Commission. On July 18, 2016, it was announced that the merger was cancelled after the State PUC disapproved the deal. The merger included plans to convert HEI's oil-fired generating plants to run on natural gas, which were to use liquified natural gas imported from a British Columbia plant of FortisBC. The upgrades were cancelled as they were dependent upon approval of the merger.
Generation
In 2016 HECO produced 8.8 TWh, of which 2.3 TWh were renewable. Most of the power came from oil, using 8.5 million barrels in 2016, down from 10.7 million barrels in 2008.Hawaiian Electric supports the adoption of electric vehicles. The company's goal is to have the majority of vehicles in Hawaii be electric vehicles by 2045. As of November 2018, it currently stands at 1% of all vehicles on the road. Hawaiian Electric filed a road map with the state.

Electric vehicles
Through a cooperative effort with HECO, High Technology Development Corporation, an agency of the State of Hawai’i, initiated the Hawai’i Electric Vehicle Demonstration Project consortium to develop an electric vehicle industry in Hawai’i. The islands have about 5,000 rechargeable vehicles.Future plans
In 2015, the Hawaii State Legislature amended the State's Renewable Portfolio Standards to establish the nation's first goal of 100% renewable energy:| Year | RPS % |
| 2020 | 30% |
| 2030 | 40% |
| 2040 | 70% |
| 2045 | 100% |
Hawaiian Electric has indicated in its Power Supply Improvement Plan that it will achieve these goals early, including achieving 100% renewable electricity for the island of Moloka'i by the year 2020.
