The development of 500 kV Extra High Voltage Overhead Transmission Lines in urban areas is constrained by limited land availability and high land acquisition costs. This study evaluates the technical and financial feasibility of the 18.3 km Muara Tawar–Bekasi transmission corridor by comparing Compact Lattice Towers and conventional towers using technical, financial, and land-price sensitivity analyses. Unlike previous studies that focused on individual tower characteristics, this research adopts a transmission corridor-based approach integrating technical performance, spatial requirements, land costs, and investment feasibility. The results show that both tower designs satisfy technical requirements. Compact Lattice Towers reduce the right-of-way width from 34 m to 28 m, lowering land acquisition costs by 54.0% and ROW costs by 17.2%, although construction costs increase by 29.3%. Both alternatives remain financially feasible, with NPV values exceeding IDR 3.1 trillion and IRR values of approximately 21%. Sensitivity analysis identifies land price as the dominant factor influencing tower selection, with an economic break-even point of approximately IDR 2.57 million/m².
