Hawaiian Electric's Waiau repower project (253 MW) selected for next stage of procurement
--------------------------------------------------------------------------------

- Proposal to replace six aging fossil-fuel generators at Waiau (253 MW) selected to advance in PUC procurement for firm renewable generation on Oʻahu.
- Six combustion turbines, similar to jet engines, will replace units built between 1947-1968; initial fuel is biodiesel, potential for renewable gas/hydrogen.
- First two units (Waiau Units 3 and 4, aged 76 and 73) to retire 2024; replacement expected in-service by 2029; all six units online by 2033.
- Project still requires final PUC approval; cost details to be filed later; expects significant savings over 30 years vs. continuing to run aging units.
