The largest renewable tender in Hawaii’s history has chosen its winners, contracting a solar and storage pipeline that exceeds anything the US state has ever seen.

Investor-owned utility Hawaiian Electric said this week the tender it launched last August had selected 16 solar-plus-storage or standalone storage projects (see table below) across Oahu, Maui and Hawaii Island, a fleet of 460MW of PV and nearly 3GWh of storage capacity in total.

The winning developers were not named at this stage, with information on project size and location due to be shared “in 30 days or sooner”. The utility – which will now start negotiating contracts with developers – noted that the deals must be endorsed by Hawaii’s Public Utilities Commission (PUC).
