HECO to replace six aging fossil-fuel generators at Waiau with flex-fuel units allowing biofuels

In Hawaii, Hawaiian Electric’s proposal to replace six aging fossil-fuel generators at its Waiau Power Plant in Pearl City with more efficient, fuel-flexible units has been selected to advance to the next stage of an energy procurement process overseen by the Public Utilities Commission (PUC).

The 253-megawatt project was one of several selected as part of a competitive procurement process for firm renewable generation on Oahu. This firm renewable generation resource will be available 24/7, is flexible to meet the needs of a modern grid using solar and wind and can run on renewable biofuels. The proposed repowering of the Waiau facility will be the largest generation project in Hawaiian Electric’s 132-year history.
