Equity and Regional Variation in PLN Grid Bottlenecks, Jakarta Flooding, and Renewable Scale-Up

Disparities in national electrical grid infrastructures represent critical barriers to sustainable development, environmental resilience, and spatial equity. In Indonesia, the institutional structure governing state electricity operations intersects with severe geographical heterogeneity, creating divergent operational conditions across metropolitan centers and peripheral islands [1]. Metropolitan Jakarta faces chronic compound vulnerabilities where recurring urban flooding events routinely jeopardize centralized distribution assets and consumer supply security [2]. Concurrently, outer regions struggle with legacy fossil dependence and structural underinvestment in transmission corridors [4]. These intersecting dilemmas highlight the urgent necessity of aligning grid reliability, climate resilience, and spatial justice.

The socio-technical dynamics of national energy planning exacerbate regional inequities during low-carbon modernization. While primary industrial and urban hubs absorb substantial capital investments, captive power dependencies and rigid long-term power purchase agreements frequently impede the integration of renewable energy sources [7]. In dense urban agglomerations like Jakarta, sea-level rise and extreme precipitation exacerbate localized grid failures, turning infrastructural fragility into systemic public vulnerabilities [2]. Simultaneously, remote and island areas face distinct reliability hurdles, where fossil-fuel displacement remains constrained by high capital expenditure requirements and underdeveloped regional interconnections [4], [5].

Existing literature on utility decarbonization often analyzes regulatory reform and climate adaptation in mutual isolation, thereby obscuring how spatial injustices manifest across interconnected regional systems. This inquiry addresses that analytical void by examining the interactions between utility governance structures, urban hydrometeorological threats, and decentralized clean generation potentials [1], [7]. Evaluating these relationships through an energy justice perspective clarifies how institutional rigidity shapes differentiated climate risks and renewable adoption rates across Indonesian provinces [5], [8].

Methodologically, this investigation employs a systematic comparative framework grounded in published utility records, environmental risk reports, and regulatory policies. By establishing comparative criteria across metropolitan vulnerability and remote grid constraints, the inquiry articulates institutional pathways toward equitable decarbonization [1], [4]. The analytical outputs provide structured insights into modernizing monopolistic electrical networks while enhancing metropolitan resilience and accelerating renewable energy deployment.
