Notes:

1. Abnormal O & M expenses such as on account of  sharp increase in water charges etc which are abnormal in nature and for which the utility shall file a separate petition

2. Base O & M(Y) = (0.025x Capital cost) escalated at the rate of 10 percent per annum after the year of commissioning to bring it to 1999-2000 level

For example if the capital cost of the plant commissioned in 1996-97 is Rs.100 cores then the base for 1999-2000 is computed as: Base O & M for 1999-2000 ('Y' in the format) = (0.025*100)* (1.10)3

Capital cost as on 31.03.1998  = 13555792566.49  - say 1355.8 Crores

Base  O & M for 1999-2000 (in format) = (0.025x13555792566.49)x (1.10) 2 = 466382413
