Winners of massive Hawaiian solar-plus-storage procurement include AES, Hanwha, Engie, EDF, Longroad

Last month, Hawaiian Electric named the winning projects in its largest ever renewable energy procurement¬† — 460 MW of solar power and nearly 3 GWh of energy storage on Oahu, Maui and Hawaii.

This week, the Hawaiian utility posted the names and revealed the winning companies and groups that will develop this historic procurement — a 50% bump to the total solar megawatts on the Hawaiian Electric system. The name, location, developer, technology, size and estimated completion dates are listed on the Hawaiian Electric renewable project status board.

Oahu will add eight new solar-plus-storage projects and one stand-alone storage project totaling 287 MW of PV and 1.8 GWh of storage. The projects include:

  • Hanwha Energy’s 60-MW/240-MWh solar-linked battery system.
  • Onyx Development (owned by Blackstone) won a bid for a 6.6-MW/26.4-MWh battery project.
  • Longroad Energy won its bid for a 120-MW/480-MWh system.
  • AES won a bid for a 30-MW/240-MWh system paired with a 46-MW solar plant.

On Maui Island, three solar-plus-storage projects and one standalone project will bring 100 MW of generation and 560 MWh of storage capacity. Projects include:

  • HECO proposed and won a “self-build” project for a 40-megawatt/160-MWh system.
  • Bright Canyon Energy will build a 42-MW/168-MWh battery linked with 42 MW of solar.

On Hawaii, two solar-plus-storage projects and a stand-alone storage project are on the way. Projects include:

  • HECO proposed and won a “self-build” project for a 12-MW/12-MWh system on Hawaii.
  • Engie North America won a bid to develop a 60 MW/240 MWh PV and battery plant.
  • EDF Renewables North America won a bid to develop a 60 MW/240 MWh PV and battery system.

Kauai achieved 56% renewable energy generation in 2019, and has logged more than 440 hours at 100% renewable energy since the beginning of 2020. The island is expected to reach more than 60% renewable generation by the end of the year, when the AES PMRF solar-plus-storage project is completed.

In a recent piece for pv magazine, Allison Hilliard and Will Giese outlined that, even on the lowest end, every MW of utility-scale solar generated creates 3.3 jobs, while the number can get as high as 21.9/MW for commercial installations and 38.7 per MW for residential. With $21.39 per hour being the base pay for an entry level solar installer in Hawaii, this procurement will directly help those who have lost employment during the pandemic.

Hawaiian Electric predicts that its system will reach 31% renewable generation by this December, and could reach 50% by year-end 2022.
