MAIBARARA Geothermal Inc. (MGI) said it has confirmed the presence of sufficient steam supply to be able to proceed with its 10-megawatt expansion project at its geothermal power facility in Sto. Tomas, Batangas.
In a disclosure to the Philippine Stock Exchange (PSE), MGI said it has completed bore output testing that confirmed sufficient steam supply under the wellheads for its 10-MW Maibarara-2 (M2) expansion project.
The company currently operates an integrated 20-MW geothermal power facility in Sto. Tomas, Batangas that it put into commercial operations on February 8, 2014.
MGI is a joint-venture company owned by PetroGreen Energy, Inc. (PGEC), Trans-Asia Oil & Energy Development Corporation, and PNOC Renewables Corporation. PGEC is a subsidiary of PetroEnergy Resources Corporation.
MGI started its expansion project in the second half of 2014 by drilling two new wells, MB15RD and MB16D, which were successfully completed five days and 14 days ahead of schedule, respectively.
According to MGI, MB16D was flow-tested from December 2014 to February 2015, while MB15RD underwent similar discharge tests from April to May 2015.
At the end of May, MB15RD, which was originally designed and drilled as an injection well, had attained commercial wellhead pressure, mass flow, and MW output at full-bore opening.
Mario Marasigan, director of the Renewable Energy Management Bureau (REMB) of the Department of Energy (DOE), welcomed the findings of MGI.
“We are pleased with the outcome of MGI’s drilling and testing programs for its expansion project and the DOE looks forward to a new 10MW power station in MGI in 2017,” said Marasigan.
Despite its modest size, MGI’s expansion unit combines the advantages of being base-loaded, renewable, and free of harmful greenhouse gas emissions.
“Just as important, the host local government unit can expect additional royalties and benefits when the new plant becomes operational,” said MGI.
