Augment Steam Production Using Idle Wells 

Energy Development Corporation (EDC) was awarded a significant grant from U.S. Trade and Development Agency (USTDA) and selected GreenFire Energy to boost geothermal power production in EDC’s geothermal fields. At EDC’s Mahanagdong geothermal field in Leyte, Philippines, GreenFire Energy will apply its Steam and 2-Phase GreenLoop (S2PGL) closed-loop geothermal technology to augment steam production in an idle well. Once successfully demonstrated, EDC will initiate a technology rollout into nearby wells and sectors at EDC’s Leyte geothermal site.

EDC is the Philippines’ biggest producer of renewable energy with 1480 MW of total capacity. Of this, geothermal energy accounts for 80% (1185 MW) of EDC’s generation capacity while solar, wind, and hydro account for the rest of the renewable power generation. The Leyte geothermal site, the largest geothermal area in the Philippines, has an installed capacity of ~723 MW and consists of two independent hydrothermal systems, namely, Tongonan in the north and Mahanagdong in the south. The USTDA grant is being used for this project to increase sustainable energy production in the Mahanagdong geothermal field.
