In a new 30 year plan Hawaiian Electric Co. sets geothermal as one of the key sources of reaching the State's aggressive renewable energy goal of 100% renewables by 2045.

As reported from Hawaii, “Hawaiian Electric Co. (HECO) has revealed its latest plan charting a 30-year course on how Hawaii could meet the state’s aggressive 100% by 2045 renewable portfolio standard (RPS), which was passed last year. The plan focuses largely on grid modernization and, of course, renewable energy.

HECO and its subsidiaries – Maui Electric and Hawaii Electric Light Co. – submitted the Power Supply Improvement Plan Update to the Hawaii Public Utilities Commission (PUC) for review. Notably, the utility companies say that based on the updates, they could collectively increase private rooftop solar by more than 250% from current levels and 370% over 2014 levels, when the companies’ last plans were prepared.

The energy plan update included detailed computer modelling of more than 130 different scenarios that could possibly meet the most aggressive energy goals in the country. The Companies’ plan calls for partnering with customers and renewable energy developers to invest in a diverse mix of renewable energy resources. By 2045, the diverse mix of resources serving Oahu, Maui County, and Hawaii Island could include up to 118 MW of geothermal power generation capacity


Under the scenario geothermal energy would be the 5th largest contributor of renewable energy, after private rooftop solar, utility-scale solar, as well as offshore and onshore wind power.
