October 11 (Renewables Now) - The state of Hawaii is set for a major boost in renewable energy after the Hawaiian Electric Companies selected seven solar-plus-storage projects that will bring 255 MW of solar and 1,055 MWh of storage to the islands of Oahu, Maui and Hawaii.

Contract negotiations are now underway between the Hawaiian Electric Companies -- Hawaiian Electric, Maui Electric and Hawaii Electric Light -- and the developers. The projects are result of a procurement process launched in February and need to be approved by the Public Utilities Commission (PUC). Each site will include a storage system that will capture up to four hours of electricity. They are expected to reduce fossil fuel use by 1.2 million barrels per year.

"These large-scale solar and battery projects will accelerate our renewable energy drive at some of the lowest prices we've seen to date," Shelee Kimura, Hawaiian Electric senior vice president of business development and strategic planning, said in a statement on Tuesday.

The selected projects include:

Location Number of projects Combined solar capacity  Combined storage capacity
Oahu 3 120 MW 515 MWh
Maui 2 75 MW 300 MWh
Hawaii 2 60 MW 240 MWh 

Innergex Renewable Energy Inc (TSE:INE) said on Wednesday it has advanced in Hawaii's competitive bidding process with two projects -- a 30-MW solar and 120-MWh battery storage facility for Hawaii island and a 15-MW solar and 60-MWh battery storage facility for Maui island -- and is now negotiating power purchase agreements (PPAs). The projects are expected to commence commercial operation in 2022.
