This chapter deals with route selection, commissioning, operation and maintenance of overhead power transmission lines. It starts with route selection followed by general considerations of understanding of purpose, resource and objective, covered area, geographical and geological diversity, political map, climatic statistics, cost study, etc. Different aspects of establishing new lines, alternate lines, lines conversion have been discussed. Linking with underground lines has been discussed. Different aspects of planning and construction like survey, planning, design, foundation, installation, erection, commissioning, responsibility and issues, check-up, test, energization, etc. have been discussed. Supervision and quality assurance in commissioning and commencement of operation have been discussed thoroughly. Operation and maintenance, post-commissioning planning and management, operation management, maintenance management, asset management, risk management have been discussed followed by uprating, upgrading and extension of line.
