comprising representatives from NTPC Ltd., Central Electricity Authority (CEA),
Gujarat State Electricity Corporation Ltd. (GSECL) and Bharat Heavy Electricals
Ltd. (BHEL) which studied various aspects of Life extension and Renovation &
Modernization (R&M) of coal based thermal power stations and brought out a
report in the form of R&M Guidelines 2023. Thereafter, based on the guidelines,
CEA identified 223 units as potential candidates after consulting with all the
concerned stakeholders for Renovation & Modernisation/ Life Extension (R&M/LE)
works with age older than 20 years as on December 2022. The R&M/LE works in
these units have to be implemented in nine phases to avoid any major energy
demand- supply gap. The details are given at Annexure.
(c): At present, the Central government neither provides funds nor has any
central sector scheme for modernization/ upgradation of thermal power plants
across India including Andhra Pradesh. The generating company is expected to
commercially finance the R&M/LE works after evaluating the feasibility.
