TSI’s 150-MW Davao plant delayed by blackout

Posted on April 07, 2015

DAVAO CITY -- The commercial operation of the first 150-megawatt (MW) coal-fired power plant of Therma South, Inc. (TSI), targeted this month, could be delayed following the Mindanao-wide blackout last Sunday, for which the cause has not yet been determined.

In a statement issued yesterday, TSI, a subsidiary of Aboitiz Power Corp., said because of the disruption, “Therma South will reassess the commissioning schedule of one of its two (2) 150-MW units and it will apprise its customers of developments.”

The power plant’s capacity, initially at 300 MW for operation this year and an additional 345 MW to be installed, has been contracted to more than 20 distribution utilities and electric cooperatives since 2014.

TSI previously announced that it was scheduled to test the plant’s links to the main grid during the first week of April.

Power supply from the main grid, operated by the National Grid Corporation of the Philippines (NGCP), was suddenly cut off around 1 a.m. Sunday, plunging the entire southern mainland into darkness.

NGCP announced at 10 a.m. Sunday that it was able to stabilize supply by 7:50 a.m. and electricity distributors have normalized operations, but the major cities of Cagayan de Oro, Davao, General Santos, Iligan, and Zamboanga are still running on embedded generators as some transmission lines are still down.

An investigation is still ongoing as to the actual cause of the seven-hour outage.

Meanwhile, TSI President Benjamin A. Cariaso, Jr. said in the statement that the commissioning of the second 150-MW unit has not been affected and remains on schedule.

Aside from TSI’s facility, other fossil fuel-fired plants that are expected to deliver supply later this year are the 300-MW coal plant of San Miguel Consolidated-Global Power Corp. (SMC-GPC) and Sarangani Energy Corp.’s 210-MW coal plant. -- with Carmencita A. Carillo and Carmelito Q. Francisco
