Fifth Power System Development Project

closed

The objective of the Fifth Power System Development Project for India is to strengthen India's electricity transmission system in order to increase reliable power exchange between regions and states. The project will consist of one component, namely regional transmission schemes for strengthening of Western, Northern and Southern region transmission systems, and the interregional power exchange for the national grid. Indeed, the first three schemes are being constructed to meet the demand in the Western and Northern regions where the Sasan Ultra Mega Power Project (UMPP) and Mundra UMPP are physically located. Both plants are expected to be commissioned in 2012-13, to facilitate the exchange of power between regions, the transmission networks have to be strengthened in the Western, Northern and Central part of the national grid system, as the difference in demand profiles across regions requires large bulk power transfers over short periods of time and the transmission networks need to have significant available transfer capacity to sustain these. Fourth scheme will meet the power demand within southern region and will transfer the power to load centers in the Western region. The fifth scheme, the South-West interconnection, will transfer power surpluses in the Southern region to deficit regions in the Western region.
