28 October, 2015, Dahanu, Maharashtra : The 1st Thermal Power Sector workshop for promoting exchange of “Best practices in Energy Efficiency in Thermal Power Sector” under Knowledge Exchange Platform (KEP) initiative was hosted by Dahanu Thermal Power Station, Reliance Infrastructure Limited, on 28th October, 2015 at Dahanu, Maharashtra. KEP is a joint initiative of Bureau of Energy Efficiency (BEE) and Institute for Industrial Productivity (IIP) for promoting energy efficiency through best practice transfer in industries covered under the Perform Achieve and Trade (PAT) scheme. KEP provides the institutional framework to catalyze the transfer of best practices within and across the industry sectors covered under PAT Scheme.
The best practice workshop in thermal power sector was an important event under KEP as it was not just relevant for 144 Designated Consumers (DCs) that have been mandated to enhance their energy efficiency under the 1st cycle of PAT scheme but for other industry sectors like cement, aluminium as well, which have sizable number of Captive Power Plants (CPP). The workshop was attended by 230 participants, which included 100 representatives of thermal power sector and 130 representatives of aluminium, cement, pulp & paper, fertilizer, textile, iron & steel sectors, energy auditors and energy managers, technology providers and senior Industry professionals amongst many others.
The workshop was inaugurated by Shri Rajendra Nandi, Project Director, Sr. Vice President, Dahanu Thermal Power Station, Reliance Infrastructure Limited. In his inaugural address, he highlighted importance of best practice sharing which will assist the industries in identifying cost-effective measures that can reduce energy consumption and developing systematic approach towards energy efficiency improvements. He also mentioned that the knowledge sharing and best practice sharing will motivate the industries to collaborate among the wider members and stakeholders. Shri Nandi hoped that this platform will also support the work being undertaken by the industries in the area of energy efficiency and to explore additional channels for the promotion of cleaner technologies.
Welcome address was delivered by Ms. Ritu Bharadwaj, Senior Program Manager, Institute for Industrial Productivity. She made a brief presentation on the rationale behind KEP, objectives and vision and the milestones achieved so far with the continued support of industries. Ms. Bharadwaj highlighted the fact that although KEP although being in infancy stage, has undertaken commendable work. Three Best practices workshops for Aluminium, Cement, and Paper and Pulp have been successfully organized, attended by more than 600 industry professionals. 60 plants from all the PAT sectors have agreed to participate in Friendly Energy Efficiency Exchange Visits. Policy Roundtables on ESCerts Trading, Financing and Spent Pot Liners (SPL), a hazardous waste, generated from the aluminium sector and its gainful utilization in the cement industry, have been organized.
She also informed the participants KEP has launched an interactive website (www.knowledgeplatform.in) that facilitates knowledge transfer and discussion between stakeholder groups related to different PAT sectors and requested participants to give their feedback on different features to ensure that it met industry’s expectations and needs. She also mentioned that IIP was committed to work alongside BEE in taking this initiative forward and helping the industry achieve PAT objectives. While concluding her welcome address, Ms. Bhardwaj hoped that with these initiatives, KEP will be able to deliver significant energy efficiency benefits for the industrial sector and help sustain continuous improvement by promoting cost effective efficiency measures.
Special address was delivered by Shri K. K. Chakarvarti, Expert Consultant, BEE. In his address, he mentioned that the success of KEP depended on pro-active industry participation. Vote of thanks was delivered by Shri Bhaven Sheth, Addl. Vice President, Dahanu Thermal Power Station, conveyed his thanks to the dignitaries, speakers and delegates for their presence and participation in the workshop and assured the full support of Dahanu Thermal Power Station in future activities under KEP initiative.

The inaugural event was followed by three technical sessions and a panel discussion. The first technical session was Chaired by Shri K K Chakarvarti, Expert Consultant, Bureau of Energy Efficiency. The discussion in the session focused on Monitoring and Verification (M&V) arrangements under PAT Scheme and Trading mechanism proposed for Energy Saving Certificates (ESCerts). BEE presented the M&V provision under PAT for Thermal Power sector, wherein the participants were informed about the current status as well as next steps proposed with regard to M&V. The presentation also covered the methodology to be adopted for second PAT cycle and the new plants proposed to be added in second cycle of PAT. The presentation on ESCerts by BEE focused on key aspects of ESCerts trading scheme and the progress made so far, which included status of ESCerts Exchange Regulations, roles and responsibilities of entities involved, formulation of business procedures for ESCerts exchange on Power Exchanges and up-gradation of PATNet Portal including M & V process.
Besides PAT, the session also focused on sharing of experience of the industry on implementation of innovative best practices. The industries that shared their experience included Dahanu Thermal Power Station, The Tata Power Company Limited, Trombay Thermal Power Station, National Aluminum Company Limited (NALCO) and UltraTech Cement Limited.
Sharing and discussing their innovative best practices, the presentation by Dahanu Thermal Power Station, focused on benefits achieved by Installation of Variable Frequency Drive (VFD), Boiler Feed Water Pump (BFP) Cartridge replacement and replacement of Manganese Liner by Hi-Crome Liner in Coal Mill, which lead to annual energy saving of 5.2 million units (MU), 2.6 MU and 6.72 MU respectively. The presentation by The Tata Power Company Limited, Trombay Thermal Power Station highlighted the energy savings achieved by modification in Air & Flue gas path in the 250 MW Unit 8, Combustion Optimization in Unit 5of 500 MW capacity and Soot blowing drain steam recovery system, which lead to annual monetary saving of Rs. 19 million, Rs. 36.3 million and Rs. 0.9 million respectively. The presentation by NALCO highlighted the energy efficiency gains achieved by reducing the Boiler Feed Regulating Stations (FRS), improvement in Turbine Condenser Vacuum, replacement of CT Fan GRP blades with FRP blades, and Dry Oil gun testing to save fuel oil consumption.Explaining new approaches to energy efficiency, a presentation by GIZ, described the importance of Coal Blending and its effects on Boiler Performance viz. the effect of Volatile Matter, Fixed Carbon, Moisture, Ash and Flame stability. The last presentation in the Technical Session 1 covered the best practices adopted by UltraTech Cement Limited (Andhra Pradesh Cement works). The presentation explained the strategy and benefits achieved by installing Boiler Feed Pump VFD Speed cascading with Drum Pressure. This helped in reducing Auxiliary consumption of the Boiler feed pumps significantly.
