USG Oregon, a subsidiary of renewable energy development company US Geothermal, has accepted Facility Substantial Completion certificate for the 22MW Neal Hot Springs project.

The certificate was placed on 17 June 2013 by technology company TAS Energy that was contracted to develop the project in Malheur County, Oregon.

As per the terms of the equipment supply agreement, TAS Energy provided three modular energy systems.

Commenting on the completion of the project, TAS Energy CEO JT Grumski said: "Collaborating with the US Geothermal team in bringing our innovative ORC technology to the geothermal industry has been a rewarding experience for the TAS Energy team and we are equally excited that our customer has achieved this important milestone."

Idaho Power, meanwhile, will procure the power output from the facility under a long term sales agreement.

US Geothermal CEO Dennis Gilles stated: "We are very excited to have completed this significant milestone. Since initially synchronizing these units to the grid in the 4th Quarter 2012, there has been a tremendous amount of work associated with optimizing the plant performance by the teams from TAS Energy and U.S. Geothermal, and their efforts are very much recognized and appreciated."
