USA, Hawaii: Utility Plans for 118 MW Geothermal Energy by 2045

HECO Submits Plan For Hawaii To Meet 100% Renewables Mandate (Solar Industry)

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.

According to HECO, the energy plan update includes detailed computer modeling of more than 130 different scenarios that could possibly meet the ambitious 100% renewable energy goal. The plan says that, by 2045, the diverse mix of resources serving Oahu, Maui County and Hawaii Island could include the following:

  • 1,215 MW of private rooftop solar energy;
  • 36 MW of feed-in-tariff solar energy;
  • 872 MW of utility-scale solar energy;
  • 529 MW of onshore wind energy;
  • 800 MW of offshore wind energy;
  • 21 MW of hydropower; and
  • 118 MW of geothermal energy.
