Energy Development Corp. (EDC) has partnered with American firm, GreenFire Energy Inc. for the commercial retrofitting of an idle geothermal well in the hanagdong geothermal facility in Leyte.
Under the partnership, the geothermal well which has not been usable due to the high level of non-condensable gases will be restored to generate new steam.
EDC said a heat mining system will correct the problem and meet its surface system pressure requirements once it is installed and commissioned by the fourth quarter of the year.
“We have been looking at GreenFire Energy’s closed-loop approach to geothermal for some time and are happy to see the progress. While we see potential for the technology in large greenfield projects too, we see the fast payback on well retrofits as the easiest way to start,” said Liberato Virata, EDC senior vice president and head of facilities operations and maintenance group, in a statement.
Virata said EDC is also working with GreenFire Energy in analyzing other unproductive geothermal wells and less productive geothermal fields to utilize the same technology.
“Being able to generate steam from our idle geothermal wells that will enable us to supply more of that much needed clean, reliable, stable power that our country needs is all a part of fulfilling EDC’s mission to forge collaborative pathways for a decarbonized and regenerative future,” Virata added.
The company has over 1,480 megawatts (MW) of total installed capacity and accounts for 20 percent of the country’s total installed renewable energy capacity.
Its almost 1,200 MW geothermal portfolio comprises 62 percent of the country’s total installed geothermal capacity.
