HILO >> Hawaii Electric Light Co. is looking at terminating its purchase agreement with Hu Honua Bioenergy LLC over delayed renewable energy efforts.

The Hawaii Tribune-Herald reports the bioenergy plant failed to meet deadlines in an agreement to provide 10 percent of Hawaii Island’s energy from renewable sources.

Hawaii Electric filed an update with the Public Utilities Commission announcing its plan to end the agreement next month.

Hu Honua CEO John Sylvia said Thursday that Hawaii Electric failed to update deadlines after a labor dispute caused an unforeseen construction delay.

Commission chairman Randall Iwase said in a statement that he was concerned about failed Hawaii Electric renewable energy efforts, slow approval for rooftop solar, and what seems to be a step back from Hawaii’s clean energy goals.

The commission plans to investigate the conduct of companies involved.
