Hawaiian Electric Co. said today it submitted plans with state regulators to revive the last of three major solar farms it cancelled last year.

HECO said it is looking to buy energy from Houston-based NRG Energy, Inc.’s Kawailoa Solar facility on the North Shore for 11 cents a kilowatt hour. The solar farm, slated to be built near Haleiwa, will be the state’s largest solar facility. Kawailoa Solar will be able to produce 49 megawatts at peak.

The state Public Utilities Commission has to approve the application as well as contracts for two other revived utility-scale solar farms that HECO submitted in January.

The three solar projects, owned by NRG, have the combined capacity to power more than 17,974 homes at peak, with a total of 109.6 megawatts of solar generation. They have the capability of increasing the renewable output on Oahu by 3 percentage points— currently, renewable energy makes up 19.4 percent of Oahu’s fuel mix.

Craig Cornelius, president renewables at NRG, said he wants to work on more projects in the state.

“We’re glad to be moving those three down the line,” Corneilius said. “We hope what we do here is not limited to the first three projects. We’ve come here because we respect what the state has committed itself to in terms of its energy transformation.”
