Renovation and Modernisation<br />

RENOVATION AND MODERNISATION OF<br />

THERMAL POWER STATIONS<br />

Introduction<br />

In order to improve the performance <strong>of</strong> existing<br />

Thermal <strong>Power</strong> Stations, a Renovation and<br />

Modernisation (R&M) Programme called Phase-I<br />

R&M Programme was launched by the<br />

Government <strong>of</strong> India all over the country in<br />

September 1984 for completion during the Seventh<br />

Plan Period. This programme was successfully<br />

completed and intended benefits were achieved.<br />

R&M (Phase-II) Programme<br />

In view <strong>of</strong> the encouraging results achieved from<br />

the implementation <strong>of</strong> Phase-I R&M programme<br />

during 7th Plan, Phase-II Programme for R&M <strong>of</strong><br />

Thermal <strong>Power</strong> Stations was taken up in the<br />

year 1990-91 by the Government <strong>of</strong> India for<br />

implementation during the 8th Plan. Under this<br />

programme, 44 Nos. <strong>of</strong> Thermal <strong>Power</strong> Stations<br />

covering 198 nos. <strong>of</strong> Thermal Units aggregating<br />

to a total capacity <strong>of</strong> 20,869 MW were taken<br />

up. The total estimated cost <strong>of</strong> the programme<br />

was Rs. 2383 crores and an additional generation<br />

<strong>of</strong> 7864 MU/year was anticipated after the<br />

completion <strong>of</strong> the programme.<br />

However about 50% works could be completed<br />

by the end <strong>of</strong> 8th Plan i.e. March 1997. After<br />

partial completion <strong>of</strong> these works, an additional<br />

generation <strong>of</strong> 5000 MU/year was achieved. Also,<br />

Life Extension (LE) works on 4 Units (300 MW)<br />

were completed.<br />

9th Plan Programme<br />

The CEA reviewed the progress <strong>of</strong> Phase-II R&M<br />

Programme and the balance activities still<br />

required to be carried out were included in the<br />

9th Plan Programme along with the subsequently<br />

identified additional activities. During the 9th Plan<br />

Programme, 127 Units (17306 MW) at 29 <strong>Power</strong><br />

Stations were taken up for R&M and another 25<br />

units (1685 MW) for Life Extension at an<br />

estimated cost <strong>of</strong> Rs.1700 crores.<br />

Life Extension works on all the 25 units planned<br />

for 9th five year plan have been completed.<br />

Chapter - 10<br />

10th Plan Programme<br />

During the 10th plan, 106 old thermal units with<br />

a total capacity <strong>of</strong> about 10413 MW at an<br />

estimated cost <strong>of</strong> Rs.9200 crores have been<br />

identified for Life Extension Works. Out <strong>of</strong> 106<br />

units, Life Extension works <strong>of</strong> 5 units & residual<br />

life assessment (RLA) studies on 62 units have<br />

been completed and further action is being taken<br />

by concerned SEBs/utilities. After implementation<br />

<strong>of</strong> life extension (LE) schemes, the economical<br />

operating life <strong>of</strong> the units will get extended by<br />

another 15-20 years besides the overall<br />

improvement in the performance <strong>of</strong> the units.<br />

Also R&M works on 57 units (14270 MW) at an<br />

estimated cost <strong>of</strong> Rs.956 crores have been<br />

identified for improvement <strong>of</strong> their performance.<br />

Programme for the year 2003-04<br />

During the year 2003-04, the work <strong>of</strong> Life<br />

Estension <strong>of</strong> 5 thermal units (440 MW) were<br />

expected to be completed, out <strong>of</strong> which LE work<br />

on 3 units <strong>of</strong> Korba East (unit 1,4&6) and 1 unit<br />

<strong>of</strong> Kothagudem (unit-8) have already been<br />

completed and the work on Kothagudem unit-7<br />

is in the advance stage <strong>of</strong> completion.<br />

RENOVATION AND MODERNISATION OF<br />

HYDRO ELECTRIC POWER PROJECTS<br />

a) R&M Phase-I Programme:<br />

Based on the recommendations <strong>of</strong> the<br />

National Committee set up in 1987 and<br />

subsequent reviews, a programme for<br />

renovation, modernization and uprating <strong>of</strong><br />

Hydro <strong>Power</strong> Stations was formulated by<br />

Central Electricity Authority in which 55<br />

schemes were identified with an aggregate<br />

capacity <strong>of</strong> 9653 MW. The total cost <strong>of</strong><br />

these schemes was estimated as Rs.1493<br />

crores and expected benefit as 2531 MW/<br />

7181 MU.<br />

b) R&M Phase-II Programme:<br />

As per the hydro policy declared in 1998,<br />

renovation & modernization <strong>of</strong> Hydro <strong>Power</strong><br />

Plants have been accorded priority.<br />

Accordingly, 67 hydro RM&U schemes<br />
