Aboitiz taps Mitsubishi Power for Davao coal plant maintenance


Aboitiz Power Corporation signed a three-year long-term service agreement (LTSA) with Mitsubishi Power to enhance the boiler reliability of its Therma South, Inc. (TSI) coal power plant in Davao City and support the power generation needs of Mindanao. 

Under the deal, Mitsubishi Power will conduct boiler ultrasonic thickness gauging mapping inspection activities at the plant, which has a 300-megawatt circulating fluidized bed (CFB).

The LTSA took effect last April and will take effect until April 2024. Inspections will be conducted by MHI Power Plant Services Corp., an affiliate company of Mitsubishi Power. 

“Therma South is a critical supplier of baseload power to the Mindanao region, and as such it is important that our operations run reliably and sustainably. We constantly look at ways to make improvements to deliver strong maintenance results across a range of solutions,” TSI Facility Head Abe Nisnisan said in a statement.

“Reliable and efficient power is the foundation of stable economic and societal growth. Mindanao had faced frequent power shortages before the completion of Therma South and so being able to help play a role in supporting this community is a very proud moment for us,” said MHI Power President Vincent Engracia. 

TSI, a wholly owned subsidiary of AboitizPower, supplements power generation required to meet the region’s baseload requirements to reduce the frequency and duration of power shortages in Mindanao, due to renewable intermittency. Back in February, AboitizPower announced that the Davao plant began tapping data science and artificial intelligence to cut emissions.

Mitsubishi Power is engaged in CFB maintenance work. The team’s technical expertise will help enhance the reliability of the power plant’s two boiler units, contributing to the provision of stable and efficient power for the region.
