Mitsubishi Power has presented a policy proposal to the Government of Indonesia to promote the adoption of biomass co-firing at the country’s thermal power plants.
The Indonesian Government is currently implementing an energy policy that aims to raise the proportion of renewables in the nation’s energy mix to 23% by 2025, as part of its goal to reach carbon neutrality by 2060.
In support of this policy, the presented proposal states that promoting biomass co-firing in the country, where thermal power accounts for a high percentage of the power generation mix, is an optimal short-term option for realising the nation’s goals.
The proposal follows studies concluded under a memorandum of understanding (MOU) in September 2020 by Mitsubishi Power (a power solutions brand of Mitsubishi Heavy Industries [MHI]); Indonesia state-owned electricity provider PT.PLN (Persero) and two of its subsidiaries, PT. Indonesia Power and PT Pembangkitan Jawa-Bali, and Institut Teknologi Bandung.
In formulating the proposal, the five MOU signatories collaborated in selecting the appropriate biomass fuel components, determining the scope of necessary facility renovation, and conducting economic evaluations.
The organisations selected wood pellets and another potential biomass fuel, which are abundantly available and stably procurable at low cost in Indonesia.
“Indonesia’s clean energy goals will require a systematic exploration of various energy sources,” said Kazuki Ishikura, president of PT. Mitsubishi Power Indonesia.
“Biomass is a low carbon and renewable fuel source. As a valued renewable resource in Indonesia, it can potentially power the country’s energy transition in the near-term.”
As candidates for facility renovations, two existing plants were considered: Paiton Power Plant Unit 1 in eastern Java, and Suralaya Power Plant Unit 2 in western Java. The policy proposal to promote biomass co-firing in the country was presented after studies were conducted on both plants.
Based on the proposal, Mitsubishi Power will conduct ‘grindability’ and combustibility testing at MHI’s Research & Innovation Center in Nagasaki on a biomass fuel deemed ‘promising’, in terms of latent volume and composition.
Mitsubishi Power will continue to support the adoption of biomass co-firing while ensuring the sustainable use of Indonesia’s abundant forest resources and excess agricultural residues.
