THERMA South Inc. (TSI), a wholly owned subsidiary of AboitizPower and operator of a 300-megawatt coal plant in Davao, said on Thursday that it availed of its allowable downtime to conduct rectification works on various operating parts of the boiler circulation system of Unit 2 of the plant.
TSI said in a disclosure that the Davao coal plant was subjected to a series of grid synchronization activities to ensure safe operation following the repairs made on the plant from February 16 to 29.
According to TSI, it is expected that reliability of a newly built complex power plant will, in the beginning, be lower but over time improve as operational issues naturally come out in due course.
“TSI will continue to operate the plant in accordance with best practices and correct any operational issues immediately as they arise,” disclosure said.
TSI declared commercial operations of the second unit of its Davao Baseload Power plant starting February 2. Unit 2 will add another 150 MW (130 MW net) to the Mindanao grid.
It earlier declared commercial operations of the first 150-MW (130-MW net) unit last September 18, 2015, allowing customers to receive 50 percent of their contracted supply.
TSI’s Unit 2 has been undergoing testing and commissioning for the past several months and has in fact been delivering, on a non-committed basis, commissioning energy to its customers at discounted rates.
Customers for the 300-MW baseload power plant consist of 20 electric cooperatives and distribution utilities in the Mindanao region which, in theory, can now receive their full contracted capacity if both plants were 100 percent operational.
The plant currently supplies a significant portion of power to the cities of Davao, Cagayan de Oro, Gen. Santos, Zamboanga, Butuan, Kidapawan, Tagum, Koronadal, Digos, Pagadian, and Cotabato, among others.
It also supplies power to the Davao region, Cotabato provinces, Sultan Kudarat, Agusan provinces, Surigao provinces, Zamboanga provinces, parts of Bukidnon, and parts of Misamis.
