本論文は、インドネシアの電力会社PLNおよびPLN NPにおけるメリットオーダーの役割を、運用効率、電力購入契約（PJBTL）構造、デジタル変革の3側面から分析する。系統的文献レビューの結果、メリットオーダーは熱効率指標や信頼性指標を統合した「ハイブリッド型」へ進化し、デジタルプラットフォームが活用されている。また、PJBTLの構造はメリットオーダーの有効性に二面性を持つことが示された。
English
This study analyzes the role of the merit order in PLN and PLN Nusantara Power, linking operational efficiency, Power Purchase Agreement (PJBTL) structure, and digital transformation. Using a systematic literature review, it finds that the merit order has evolved into a hybrid model integrating thermal efficiency and reliability indicators, supported by digital platforms. The PJBTL structure has ambivalent effects on merit order effectiveness.

📄 Abstract（原文）
This study aims to analyze the role of the merit order as a portfolio optimization mechanism for power generation within PLN and PLN Nusantara Power (PLN NP) by linking three key dimensions: operational efficiency, the structure of Power Purchase Agreements (PJBTL), and digital transformation. The method employed is a Systematic Literature Review (SLR) of journal articles, corporate reports, regulations, and official documents related to merit order, PJBTL, generation portfolio strategy, and the digitalization of Indonesia’s electricity system over the period 2010–2025. The findings indicate that the implementation of the merit order in PLN and PLN NP has evolved from a classical model based solely on marginal cost into a “hybrid merit order” that integrates thermal efficiency indicators (SFC, NPHR), unit reliability (EAF, EFOR), and generation mix, supported by digital platforms such as Dispatch Optimization, i-CORE, and the Nusantara InnoVision Center. The PJBTL structure is found to be ambivalent: IPP contracts based on take-or-pay schemes and long-term primary energy contracts limit dispatch flexibility and reduce the effectiveness of the merit order, while PJBTL arrangements with industrial customers contribute to stabilizing base load and expanding operational flexibility. From a commercial perspective, this study confirms that growth in electricity sales only improves performance when additional demand is supplied by low-cost units that are competitive within the merit order. Otherwise, increased TWh sales risk becoming “pseudo-growth,” where production costs (BPP) remain high and margins do not significantly improve.
