Biogas from Honouliuli Wastewater Treatment Plant will generate revenue for the City

HONOLULU (Sept. 13, 2017) – Hawaii Gas, the state’s only regulated gas utility, received approval from the Hawai‘i Public Utilities Commission (PUC) to install equipment to capture and process biogas from the Honouliuli Wastewater Treatment Plant. Hawaii Gas was awarded the contract from the City and County of Honolulu in July of 2016 after a competitive bidding process.

“Incorporating cost-effective renewable natural gas as part of our fuel mix is a key priority as we continue to do our part to advance Hawaii’s clean energy future,” said Alicia Moy, president & CEO, Hawaii Gas. “We look forward to pursuing similar projects that deliver renewable fuels to our customers and new revenue streams to the City. This is a win-win partnership for the residents of Honolulu and our customers.”

The Honouliuli Wastewater Treatment Plant produces about 800,000 therms of energy per year, which is currently not being utilized. By selling the biogas, the City and County of Honolulu will generate approximately $1.6 million of revenue per year.

The awarded contract expires December 31, 2024, with a provision to extend the term. Hawaii Gas will invest about $5 million in the infrastructure to process the raw biogas and to connect the Honouliuli Wastewater Treatment Plant to the company’s existing pipeline. The project is estimated to be operational by the end of 2018.
