Isolation has its merits, but in Hawaii the same seclusion that lures planeloads of tourists also severs the state from its sources of energy.

While the rest of the country’s transportation system relies almost solely on oil, Hawaii remains heavily dependent on petroleum for nearly 90 percent of all its energy needs, including electricity generation. The state’s four largest plants — and 9 of the 10 largest — are primarily powered by petroleum. The amount of oil arriving by ship is of great concern for a state that values its environment and the tourism dollars that come with it. But the energy mix has also led to backbreaking electricity rates that are twice as high as the next costliest state and nearly three times the national average.

Hawaii Celebrates Alternative Energy Achievement

Hawaii’s commitment to alternative energy recently reached a milestone. According to Business Week, Hawaiian Electric Co. has reached 20 megawatts of solar photovoltaic energy on the island of Oahu. The utility said the mark was reached in July when they installed Easter Seals’ PV system. Easter Seals, a non-profit health agency, received $5,000 as a gift.

Nearly 4,000 Oahu customers benefit from solar power. They can also benefit from a feed-in tariff scheme whereby they can sell excess electricity back to the grid.

More solar power capacity is being added. This week, Forest City Hawaii and Hawaiian Electric Company announced they have reached a power purchase agreement for up to one megawatt of solar photovoltaic (PV) power to be generated at the Kapolei Sustainable Energy Park in Kapolei, also in Oahu.

SolarCity Corporation (San Mateo, California, U.S.) and Lend Lease Corporation Ltd. (Millers Point, Australia) announced that construction has begun on a 4 MW solar photovoltaic (PV) project at Joint Base Pearl-Harbon Hickam near Honolulu, Hawaii.

The initial phase will involve the installation of PV systems on 600 roofs on the base. SolarCity will engineer, install and maintain the systems, and sell the electricity generated to Hawaiian Electric Company Inc. (Honolulu, Hawaii, U.S.) through a 20-year power purchase agreement.
