3. Per Capita CO2 emissions have increased at a
CAGR of 3.58%, wrt the year 1960.
With this CAGR, by 2030, Per capita CO2
emissions is expected to be 3.164 Metric Ton

4. Issues…
• The GDP growth target is > 8%.
• This requires power supply – demand gap to be lessened.
• 81% of Indian Power Sector is based on fossil fuel
• Dwindling Fossil Fuel reserves & Climate Change
Debate have put a question on the energy security issue.
• Post Fukushima – Daiichi, Nuclear Energy seems to have
taken a backseat globally.

6. • Renewable Energy is a better alternative.
• But Renewable Energy Output vary with
geographical & climatic conditions, therefore unfit
to cater to the Base Load Demand.
• Therefore, thermal power is going to be the base.
• 210 MW to 500 MW units comprise thermal
power sector mix.
• Of these almost 60% are operating for over 15 –
20 years with reduced efficiency, reliability &
enhanced GHG emissions.
• Therefore, until alternative energy sources &
associated technology become viable, R&M & LE
works of thermal power units is a better option.

7. • Improves Generation Capacity
• Improves Plant Efficiency by almost 26-34%
• Reduced fossil – fuel consumption relaxing the
already dwindling resources.
• Results in reduced GHG emissions
• Improves Availability & therefore reliability
• Improves Safety
• Low Cost option as against decommissioning of
old units & commissioning of new efficient units
• Short gestation period

9. • Prioritization of projects
• Preliminary estimate of costs and schedule
• Energy Audits, RLA & CBA
• Ranking of equipment/scope definition
• Initial estimate of costs and schedule
• Decision on run/repair/replace
• Monitoring of rehabilitation results
• Input to corporate planning

10. R&M in India
major concerns
• Shortage of agencies to conduct competent R&M
techno-commercial studies
• Lack of competent agencies to carry out R&M work
• Extended Shut down period required for R&M,
which is a bane in times of supply demand gap
• Lack of standardized documents like Test Report,
DPRs, Technical Specification, Tenders & Contracts
• Limited standardized R&M cases in India
SAYAN AICH

11. • Lack of internal expertise for proper evaluation of
equipment’s condition, cost involvement for
R&M & payback.
• Cost escalations due to “surprises” during project
execution & difficulty in inclusion of the same
into contract
• Uncertainty in capital cost approval &
reasonableness of tariff for recovery of capital
cost. Therefore delay between design & bidding
• Uncertainty in plant performance post R&M as
against what was envisaged.

12. GERMANY INDIA
Total R&M/LE, after complete
life exhaustion & when reliability –
Area specific R&M whenever
efficiency are at stake or in most
economically viable
cases, when available coal is of
much lower quality than design
Initiated with Climate Change & Primary focus is on life-time
Efficiency Issues being in focus extension and PLF enhancement
Lack of Detailed Planning
Detailed Planning Exercise before
Exercise , therefore, Longer Unit
project execution
Outage
Close association with EPC

13. • With PAT scheme of the NMEEE, it is evident
that the country focus has lately shifted to
Efficiency & GHG mitigation drive, in vogue
globally.
• Therefore it has become imperative that the
R&M of old thermal power units must be
carried out as early as possible.
• Timely R&M / LE works will ensure reduced
GHG emissions, enhanced efficiency &
increased reliability & availability.
SAYAN AICH

14. • The ambitious R&M Plan of India till 2022,
provides a huge opportunity for global players
in this field.
• Dearth of competent consultants and/or EPC
contractors can be filled in by agencies all
across the globe.
