Uninterrupted operation of flight navigation equipment is paramount for aviation safety. This investigation critically assesses the power supply adequacy and optimizes the backup power system architecture at Perum LPPNPI Palembang to guarantee 24/7 operational continuity for its critical navigation infrastructure. Employing a hybrid quantitative-qualitative methodology, the research quantifies the peak and normal power demands of critical navigation systems including the Instrument Landing System (ILS), Doppler VHF Omnidirectional Range (DVOR), and Distance Measuring Equipment (DME) through technical data analysis and field verification. The reliability of the primary power grid (PLN) and the performance of the existing backup infrastructure (generator sets and UPS) are evaluated based on capacity, condition, and switchover time. The analysis reveals a primary power supply availability of 97.78%, underscoring a significant reliance on backup systems. While the existing backup capacity (872.4 kW from generators and 238.32 kW from UPS) substantially exceeds the 65.65 kW critical load, a critical gap is identified in the form of aging assets, notably a 20-year-old generator and several UPS units exceeding their technical lifespan. A strategic asset renewal plan is consequently proposed to mitigate the risk of catastrophic failure. The findings provide a tangible framework for enhancing electrical infrastructure resilience, directly contributing to the safety and efficiency of air navigation services
