Adequate capacity addition and its utilization in the most optimized manner is the most important aspect of the power development. EHV power system has seen rapid growth over last two decades, both in terms of higher transmission system voltages touching 765 kV UHV AC & +/- 800 kV HVDC and physical network size spreading through out India and even 1200 kV UHV AC station has been built on experimental basis for future implementation of the highest system voltage transmission lines. Commensurate with the capacity addition, this extensive network of transmission and distribution developed over the years is being used for evacuation of power generated and utilizing the same by the ultimate consumers. The new capacity additions call for further strengthening of the transmission system. The transmission capacity addition programme is continuously monitored by the Power System Project Monitoring Division in the Central Electricity Authority. 1.2 MONITORING The objective of Project Monitoring as enunciated under Section 73(f) of the Electricity Act, 2003 is to promote and assist the timely completion of schemes and projects for improving and augmenting the electricity system. The objective of monitoring is realized through the managerial techniques of “Planning & Control”. The two deliberative elements of Planning & Control are inter- dependent and are essential to every phase of capacity additions in the transmission systems. The primary responsibility arising under the planning element is the finalization of the Programme of Construction activities of transmission works for the year and laying down the general principles on the basis of which it will operate. These general principles basically involve availability of the finances, land, supply of materials and various statutory clearances to undertake construction works etc. The construction programme for the year is finalized and distributed properly into the four quarters of the year. 1.3 ROLE OF CEA The Power System Project Monitoring Division of CEA has been entrusted the responsibility of monitoring the progress of construction activities of the transmission schemes of 220 kV and above in the country which are required for providing the startup power and evacuation of power from the new Generation projects and system strengthening of the Regional Grids to meet the requirements at the consumer end. The progress of the various activities of the transmission schemes under execution by the Central/State/Private Utilities in the Country are closely monitored on weekly/fortnightly/monthly basis for timely commissioning. 1 | P a g e Transmission capacity addition during 12th Plan(2012-17) in India – A report by CEA Central Electricity Authority The various activities, in case of transmission lines, include monitoring of progress of tower foundations completed and towers erected and stringing of conductor and earth wire completed out of the total length and in case of substations, the activities like acquisition of land, construction of Control Room Building, casting of structural and equipment foundations and erection of equipment, erection of Transformers, erection of Switchgear and Control Panels and commissioning activities are monitored. Assistance in various impending issues like Forest clearance, RoW problems, Railways clearance, Road Highways Clearance, Aviation Clearance etc., is provided. Visits of the officers of PSPM Division, are also made to the sites for on the spot assessment of progress of works and rendering the advice/assistance to project authorities in solving the site problems and in avoiding or reducing time overruns of the on-going transmission schemes. The site visits by the Officers of the Power System Monitoring Division and the “Review Meetings” held in the Central Electricity Authority with the Utility representatives provide an excellent ground for inter-action to identify bottlenecks and action required to ensure completion of schemes as per targets. 1.4 CONTENT The Report comprises of five chapters. In the present chapter the role of Central Electricity Authority and the monitoring principles are summarily discussed. Chapter-2 mainly focuses on the transmission capacity addition during the 12th plan period. During this period about 110370 ckm of EHV lines and transformation capacity of 331214 MVA/MW was added in the country. This chapter also covers salient features of 12th plan and brief evaluation of transmission projects. Chapter-3 presents the transmission lines and transformation capacity additions (220 kV and above) during various plan periods till the end of 12th plan in India. Chapter-4 presents the growth of inter-regional capacity since 6th plan and programe for FY 2017-22. Chapter-5 presents the detail of transmission system associated with the generation projects commissioned during 12th plan. 2 | P a g e Transmission capacity addition during 12th Plan(2012-17) in India – A report by CEA Central Electricity Authority CHAPTER -2 ACTUAL TRANSMISSION CAPACITY ADDITIONS DURING 12th PLAN (2012-17) The programme for construction of transmission works for 12th plan period for evacuation of power from generating stations as well as for system strengthening, 107440 ckm of EHV transmission lines and 282750 MVA/MW transformation capacity was envisaged. The capacity finally added was 110370 ckm EHV lines (220 kV & above) and 331214 MVA/MW transformation capacity (220 kV & above). The details are furnished below; A.
