STATEMENT
STATEMENT REFERRED TO IN REPLY TO PARTS (a) TO (e) OF STARRED QUESTION NO. 24 TO BE ANSWERED IN THE LOK SABHA ON 25.02.2016 REGARDING RENOVATION AND MODERNISATION OF THERMAL PLANTS.
*********
(a) : Details of thermal power plants in the country along with their capacity, sector-wise and fuel-wise as on 31.01.2016 is as under:
Sector No. of Plants/(Capacity in MW) Total (No. of Plants/ Capacity)
Coal (No. of Plants/ Capacity) Lignite (No. of Plants/ Capacity) Gas (No. of Plants/ Capacity) Diesel (No. of Plants/ Capacity) Multi-fuel (No. of Plants/ Capacity)
State Sector 69/ 59070.50 3 / 790 34 / 6975.30 41/ 438.57 1 /60 148 / 67334.37
Central sector 31 /46740 7 /3240 14/ 7555.33 - - 52 / 57535.33
Private Sector 79 / 63507.37 3 /1830 28 /9978 8 /554.96 - 118 / 75870.33
Total 179 / 169317.87 13 /5860 76 / 24508.63 49 / 993.53 1 / 60 318 / 200740.03
(b) & (c) : Decision to conduct Renovation and Modernisation (R&M) works and replacement are taken by the respective Utilities. R&M works of units of 13,044 MW capacity older than 25 years has started. In addition, as per assessment made by Central Electricity Authority (CEA) in Oct 2015, units of 5580 MW capacity which are older than 25 years has been identified for R&M / Life extension (LE). Further, 5860 MW capacity can be retired in due course of time in a phased manner. Retirement or R&M of units of 4800 MW capacity can be decided based on their viability.
The general norms laid down by CEA in the guideline for R&M / LE works (Oct, 2009) are as under:
• Life Extension through comprehensive R&M focuses on plant operation beyond their original designed economic life of 25 years. Specific residual life assessment studies (RLA) of critical components may be carried out after about 20 years of life or 1,60,000 hours of operation for thermal power stations.
• The cost of Life Extension works shall not exceed 50% of the EPC cost of a new generating unit of indigenous origin (BHEL). If the LE works are limited to Boiler Turbine Generator (BTG), the cost ceiling shall be restricted to 50% of the cost of new BTG unit.
• A detailed study should be carried out to ensure its techno-economic viability in terms of internal rate of return, payback period etc. The payback period may be limited to 5-7 years. In cases, where the cost is estimated to exceed the above limits, a detailed cost comparison & cost benefit analysis shall be carried out between the R&M/LE work and that of setting up a new green field plant.
• A total shut down period of unit for carrying out LE works should be 6-8 months.
(d) : About 10,180 MW capacity based on Supercritical technology can be installed after replacement of old units of 5860 MW. The total estimated fund requirement is around Rs 70,000 crore. Funds are arranged by the respective Utilities for R&M and replacement of units.
(e) : To facilitate the implementation of R&M of Thermal Power Stations (TPSs), the following steps have been taken:
• Studies have been taken up for addressing the barriers to R&M implementation under the “Coal-Fired Generation Rehabilitation Project-India”.
• RLA reports / Detailed Project Reports (DPRs) of R&M projects are being prepared by the empanelled R&M consultants.
