Amid fuel uncertainty and the rising challenge of emission control the power ministry proposes to promote renovation and modernisation of coal based power plants of central and state power utilities with annual generation capacity of 30,000 Mw. The Central Electricity Authority has invited expressions of interest from consultancy firms and institutions for empanelment to provide consultancy for preparation of a detailed project report for these projects.
CEA said that there is 120,875 Mw of coal fired generation capacity as on December 31st 2012.
State sector utilities own a little more than half of these. R&M of existing plants is in many cases the least cost option for more generation.
CEA estimates 30,000 Mw of the capacity is in need of R&M for improvement in the plant load factor and the heat rate by 10 to 15%. This will hep save coal and with a corresponding reduction in carbon dioxide emission.
Mr C P Jain, former chairman of NTPC the country's largest generation company said that "It is the need of the hour to save fuel increase generation and protect the environment. However there has to be a well laid procedure for fast decision making on the new requirements after opening up of the machine. Experience shows that due to this problem R&M efforts could not pick up or be completed."
The National Electricity Policy has said all existing generation capacity should be brought to acceptable performance standards on efficiency, reliability and environment performance.
