The increase in global power demand has caused most of today's power networks to become overloaded especially in Sub-Saharan Africa. The increased load demand can be met through expansion of existing generation and transmission system. However, construction of new power infrastructure is limited by financing and technical constraints.

State estimation is one-way such knowledge could be achieved by estimating voltage magnitudes and phase angles at all buses in electrical networks. Electric utilities are deploying advanced Phasor Measurement Units (PMUs) in grids with conventional Remote Terminal Units (RTUs).

- Modern power systems need advanced monitoring and control, achievable through Phasor Measurement Units (PMUs) enhanced by synchrophasor technology, which requires optimal placement to manage costs effectively.
- This study analyzes PMU placement in the Nairobi Region's 30-bus power transmission network using three methods: Depth-First, Mixed Integer Linear Programming (MILP), and the Artificial Bee Colony (ABC) algorithm, with initial testing on IEEE-14 and 30 bus systems.
- The findings reveal that the ABC algorithm achieves the best results, providing the highest System Observability Redundancy Index (SORI) without considering Zero Injection Buses, indicating that 12 PMUs must be optimally located for complete observability in the
