Our commitment to help achieve a carbon neutral future for Hawai‘i includes diversifying into other renewable and clean technologies and continuing to expand our energy portfolio. They represent our commitment to seek out ways to provide our customers with the energy they need to thrive while being mindful of our carbon footprint.

Sheraton Waikiki Cogen/Combined Heat and Power

The Sheraton Waikiki Cogen/Combined Heat and Power project on Oahu uses combined heat and gas power to produce electricity and has the capacity of approximately 2 megawatts. Benefits include onsite production of power, reduced energy costs and reduction of emissions compared to conventional electrical generators and onsite boilers.

Waihonu Solar Farm

Hawaiʻi Gas’ Waihonu Solar Farm is one of Oahu’s largest active solar farms and produces a combined output of 6.5 megawatts of electricity—enough to power approximately 1,000 homes. It consists of 26,232 solar modules and 13 inverters, and is situated on 12 acres of the privately owned 143-acre campus of Honbushin International Center in Mililani. The overall campus includes farmland and was historically used by Dole for growing pineapple. This 20-year project was commissioned in 2016 and continues to produce renewable energy to residents on Oahu.

  • Waihonu Solar Farm is contracted to sell electricity to Hawaiʻian Electric Company under a power purchase agreement.
  • The direct current (DC) electricity generated by the solar panels at Waihonu Solar Farm is converted by onsite inverters to alternative current (AC) electricity for use by Hawaiʻi Electric’s customers via the electric utility’s grid.
