Throughout the lifecycle of a power plant, utility companies must decide the implementation of operation and maintenance (O&M) through investment planning. Additionally, the data available to support the investment plan decision in terms of O&M management are affected by a number of variables. This paper provides an innovative approach to identify possible data and decision-making approaches in O&M investment planning in a power generation company. It takes a case study of PT PLN (Persero), also known as PLN, the electricity provider in Indonesia that focuses on the power generation sector and constantly involves decision-making for power plant O&M through investment planning. Throughout the course of the study, seven additional decision-making factors, namely, urgency, alternative study, technical feasibility, financial feasibility, land, environmental and social, legal, and Governance, Risk, and Compliance (GRC), are uncovered in the existing investment planning model. It has been determined that these aspects could be backed by data derived from best practices or those already present in the PLN. Furthermore, this paper also recommends potential future improvements that can be implemented in the power generation O&M management investment planning. As a future improvement, a more structured decision-making process, such as the SALVO process, should be implemented to support the effort to create a robust and transparent decision-making process to realize continuous asset value growth.
