Maibarara-1 Geothermal Plant Reaches 600 GWh Generation Mark

November 10, 2017



Maibarara Geothermal Inc. (MGI)’s 20 MW Unit-1 in Sto Tomas, Batangas reached its 600 GWh generation mark during the billing period ending October 25, 2017. This milestone was achieved three years and eight months from the start of the facility’s commercial operation on February 8, 2014. MGI President F.G. Delfin Jr., declared “Apart from the scheduled annual maintenance shutdowns, we have managed to minimize forced outages in the facility leading to very high capacity and availability factors.” MGI is 65% owned by PetroGreen Energy Corp. (PGEC), 25% by Phinma Energy, and 10% by PNOC Renewables Corp. PGEC is the renewable energy holding firm of publicly-listed PetroEnergy Resources Corp. (PERC).

At the time it was put on-line to the Luzon grid, Maibarara-1 was the first geothermal power station built in Luzon in 16 years and the first renewable energy project declared commercial by the Department of Energy under the framework of the 2008 Renewable Energy Law. The Maibarara-1 plant was also recently declared as the Best Renewable Energy Project in the national grid category of the ASEAN Energy Awards 2017 held during the ASEAN Energy Ministers Meeting in Manila in September, 2017.

MGI’s expansion project, the 12 MW Maibarara-2, is currently being finished to meet target commercial operation by December, 2017. MGI Power Plant Manager Paul Morala said “MGI together with National Grid Corp. of the Philippines (NGCP) installed the revenue meter of Maibarara-2 on September 30. MGI and MERALCO engineers jointly and successfully completed on October 24 the testing of Maibarara-2’s protection relays and circuit breakers. And on October 29, the unit’s SCADA system and Direct Transfer Trip (DTT) function passed MGI and MERALCO testing. We commend the highly professional and helpful cooperation we have received from NGCP and MERALCO. We anticipate such cooperation to continue and to extend as well to other agencies such as the DOE, ERC, and PEMC as the unit’s commissioning and testing enter their final phases.”
