U.S. Geothermal is advancing two renewable projects in California and Guatemala, which could add about 80MW to its annual power generation capacity.

The company has completed a flow test programme on the three production wells at the WGP Geysers site in Sonoma County, California.

They have confirmed the existence of about 30MW of steam. The reservoir report, which is expected by the end of this month, will be used to guide final development of the project.

In Guatemala, the company’s subsidiary, U.S. Geothermal Guatemala, started drilling EC-2 well at the El Ceibillo project.

U.S. Geothermal CEO Dennis Gilles said: "With approximately 30 megawatts of steam drilled, tested and ready for production at Geysers, we are actively pursuing discussions in support of a power purchase agreement for this, our most advanced stage development project.

"Additionally, our geothermal concession in Guatemala holds great promise and we anticipate that the drilling results from our next few wells will allow us to confirm the geothermal resource. We expect to be able to produce from 25 to 50 megawatts of electricity when the project is completed."

U.S. Geothermal is engaged the development, production and sale of electricity from geothermal energy.

The company is currently operating geothermal projects in several states with a power generation capacity of about 45MW.

U.S. Geothermal is planning to reach 200MW of generation capacity by 2020 via internal developments and strategic acquisitions.
