The electrical system in the Batam-Bintan region faces unique challenges in accommodating the penetration of Solar Power Plants (PLTS). This study aims to analyze the vulnerabilities of the electrical system in the region by considering five key indicators: system inertia, system ramp rate, technical minimum loading, system strength index, and system reserve margin. The research was conducted through simulations using power system analysis software to evaluate the impact of PLTS penetration on the system's stability, reliability, and operational flexibility. The analysis results show that PLTS penetration has a significant impact on system inertia dynamics, which affects the initial frequency response. Additionally, the system ramp rate shows an increased need for adjustments to accommodate PLTS power fluctuations. The technical minimum loading of conventional power plants becomes a critical concern as it influences operational efficiency. The system strength index also indicates a decline in some high-penetration scenarios, potentially affecting voltage stability. On the other hand, the system reserve margin exhibits changes depending on load patterns and the contribution of PLTS power. This study provides strategic recommendations for managing PLTS penetration through enhanced system reserve capacity, the development of energy storage technologies, and the optimization of power plant operation settings. With this approach, the Batam-Bintan electrical system is expected to integrate PLTS sustainably without compromising system reliability and stability
