EMBRACING GIS, GPS, INERTIAL NAVIGATION AND LiDAR SENSORS TECHNOLOGY IN EVALUATION AND COSTING OF HIGH VOLTAGE TRANSMISSION LINE PROJECTS (A Case Study of Kenya Electricity Transmission Company-KETRACO)

Electricity is an essential part of our everyday lives. Kenya Electricity Transmission Company Limited (KETRACO), which is responsible to plan, design, construct, own, operate and maintain high-voltage electricity transmission lines, fiber optic cables and associated substations was established to develop new high voltage electricity transmission infrastructure that will form the backbone of the National Transmission Grid, in line with Kenya Vision 2030. The general challenge that this company will encounter in the construction of new transmission lines comprises of rights-of-way, vegetation management, public concerns over potential effects and acquisition environmental approvals. The other drawback despite the fact that I will not be addressing in this exercise is vandalism, which is more common in distribution system. Today in Kenya, Electric utilities like Kenya Power and Lighting Company (KPLC) are realizing the benefits of GIS technology in the management of facilities for engineering, construction operations, and maintenance and services purposes. The main objective of this study is to do an extensive investigation on how GIS can be used in power transmission projects to determine its cost by unifying all the factors that determine a cost of a HTVL.

The cost of a Power Transmission Line is not merely determined by path between the start and end points but many other factors. It is therefore important to consider not only the technical issues but also the impact on natural environment, the influence on local community, and various regulations during the site evaluation process.

Although the exact set of factors to be considered may change in different parts of the country, most PTL routing requires attention...
