Identifying Coal-fired Power Plants for Early Retirement in Java Island - Indonesia

Suksmo Satriyo Pangarso, Jaka Aminata, Nugroho B.M. Sumarjiyanto

Abstract


The Indonesian government has already announced the early retirement of coal power plants as a part of its goal to achieve net-zero emissions (NZE) by 2060 or earlier. However, there has been no in-depth study related to (1) how to choose a power plant that will be retired early and (2) the priority of the power plant that will be retired. This research will provide information about the priority of a coal power plant (CFPP) on Java Island, which is proposed to be retired early by using the fuzzy analytical hierarchy process method. The criteria used in this study are age, performance, generation cost, release of CO2, the number of people affected and the distance of CFPP to a renewable energy source. This study informs that CFPP that is prioritized for early retirement, is the closest power plant to alternative renewable energy sources. The age of the plant and the resulting emissions are the second and third considerations, respectively. Then, we tested the method on 10 sample CFPP (with range capacity 500-1000 MW) on Java Island. The result shows that CFPP-C will be the most prioritized powerplant to be retired first.
