Maibarara eyes start of P1.3B expansion project by 2017


The Maibarara Geothermal Inc. (MGI) in Sto. Tomas, Batangas is eyeing commercial operations of its P1.3 billion10 megawatt (MW) expansion project by July 2017.

MGI President Francisco Delfin Jr. said the expansion project, which will be located just beside their existing 20-MW geothermal power plant, would require construction of another production well.

“For our 10-MW expansion project, we just need another well, which is currently on heat-up before the discharge testing,” he said. “When they will be fully opened, we have an excess capacity of 7 MW,”

Delfin said they could determine the well’s output within two weeks but “we believe we have sufficient steam based on our self-estimation for the 10-MW expansion project.”

“From August of 2015, the construction will take about 20 months. We are looking at July 2017 to start the commercial operation of our expansion project,” said Delfin.

The 20 MW Maibarara geothermal project started commercial operation on February 8, 2014. It is the newest geothermal power facility in the country and the first under the Aquino administration.

MGI is a joint-venture company owned by PetroGreen Energy Corp. (PGEC) a wholly owned subsidiary of publicly listed PetroEnergy Resources Cop. (PERC), TransAsia Oil & Energy Development Corp. (TAO) and PNOC Renewables Corp. (PNOC-RC).

The Maibarara project is an integrated power facility comprising of steamfield, power station, and transmission line.

The steam field was designed and constructed by MGI. EPC contractor EEI CORP with Fuji Electric of Japan supplying the main plant equipment built the power plant.

MGI’s power plant is linked by a 5-km long 115 kV transmission line to the Luzon grid through the distribution system of Manila Electric Company.

The facility was synchronized to the Luzon grid on November 4, 2013 in coordination with Meralco and National Grid Corp. of the Philippines.
