Renovation & Modernization - Practices in India against Global
0 likes423 views
The document discusses India's increasing per capita CO2 emissions and the need to improve the reliability and efficiency of its aging thermal power plants through rehabilitation and modernization projects. It notes that 81% of India's power sector relies on fossil fuels and outlines plans to rehabilitate 205 thermal power units between 2012-2023, bringing improved generation capacity, efficiency gains of 26-34%, and reduced emissions. However, it also identifies several concerns around R&M projects in India like a shortage of competent agencies and standardized processes.

- 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 SAYAN AICH
- 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 SAYAN AICH

- 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 SAYAN AICH
- 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. SAYAN AICH
- 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 Lacuna in coordination with Contractor to formulate Detailed EPC Contractor Plan SAYAN AICH
- 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. SAYAN AICH
