Per Capita CO2 emissions have increased at aCAGR of 3.58%, wrt the year 1960.

With this CAGR, by 2030, Per capita CO2emissions is expected to be 3.164 Metric Ton

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.

• Renewable Energy is a better alternative.• But Renewable Energy Output vary with

geographical & climatic conditions, therefore unfitto 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 & LEworks of thermal power units is a better option.

• 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

R&M in Indiamajor 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

• Lack of internal expertise for proper evaluation ofequipment’s condition, cost involvement forR&M & payback.

• Cost escalations due to “surprises” during projectexecution & difficulty in inclusion of the sameinto contract

• Uncertainty in capital cost approval &reasonableness of tariff for recovery of capitalcost. Therefore delay between design & bidding

• Uncertainty in plant performance post R&M asagainst what was envisaged.

GERMANY INDIA

Area specific R&M whenever economically viable

Total R&M/LE, after complete life exhaustion & when reliability –efficiency are at stake or in most cases, when available coal is of much lower quality than design

Initiated with Climate Change & Efficiency Issues being in focus

Primary focus is on life-time extension and PLF enhancement

Detailed Planning Exercise beforeproject execution

Lack of Detailed Planning Exercise , therefore, Longer Unit Outage

Close association with EPC Contractor to formulate Detailed Plan

Lacuna in coordination with EPC Contractor

SAYAN AICH

• With PAT scheme of the NMEEE, it is evidentthat the country focus has lately shifted toEfficiency & GHG mitigation drive, in vogueglobally.

• Therefore it has become imperative that theR&M of old thermal power units must becarried out as early as possible.

• Timely R&M / LE works will ensure reducedGHG emissions, enhanced efficiency &increased reliability & availability.

SAYAN AICH

• The ambitious R&M Plan of India till 2022,provides a huge opportunity for global playersin this field.

• Dearth of competent consultants and/or EPCcontractors can be filled in by agencies allacross the globe.
