Encouraged with the results of R&M/Life Extension works carried out during 7th and 8th Plan, the 9th Plan R&M Programme was taken up in 127 units at 29 thermal power stations. Most of the R&M activities identified under 9th plan programme have been completed.
The economic deigned life of the thermal power units is considered to be 25 years. 25 nos. of thermal units which had already completed their designed life were planned for LE works based on Residual Life Assessment (RLA) studies during the 9th Plan. The LE works on all the units have now been completed.
