The Government of India has identified Cheyyur in Kanchipuram district, Tamil Nadu, as one of several sites for a 4000 MW ultra-mega power plant (UMPP) using imported coal and super-critical technology. Super-critical technology claims to attain far higher thermal-electrical conversion efficiencies than sub-critical plants, thereby maximizing the conversion of coals embedded thermal energy into electricity. The coal would be brought in through a captive jetty-cum-port located between the fishing villages of Panaiyur Periakuppam and Panaiyur Chinnakuppam.
The port will occupy a 650 meter shorefront.
A coal stocking yard capable of storing 310,000 tonnes of coal will be constructed on 83 acres of coastal land abutting the two fishing villages. A 6.5 km conveyor belt running over dunes, fields, orchards, densely wooded areas and water bodies would carry the coal to the power plant. Various documents provide varying figures -- between 415 and 489 hectares -- for the land requirements of the power plant and its ash dyke.
The Ministry of Power aims to develop the UMPPs on a Build Own Operate (BOO) basis, through the Power Finance Corporation Ltd (PFC), a public sector unit. For the Cheyyur project, PFC has set up a Special Purpose Vehicle (SPV) called the Coastal Tamil Nadu Power Limited, based in New Delhi. The SPV is solely meant to acquire land, perform the EIA, obtain the various clearances and hand over the project to a private party who wins the bid for the project, thus saving the private party the trouble of land acquisition, impact assessment, public consultation and environmental clearances [3].
