Training Workshops on energy audit services and dissemination programs under GEF–UNIDO–BEE project during July 2015

UNIDO is implementing a GEF-funded project titled ‘Promoting Energy Efficiency and Renewable Energy in selected MSME Clusters in India', with BEE as the project management agency. This project aims to develop and promote a market environment for introducing energy-efficient technologies (EETs) and enhanced use of renewable energy technologies (RETs) in process applications in 12 selected energy-intensive MSME clusters in India covering five sub-sectors: ceramics, hand tools, foundries, brass, and dairy.

BEE had engaged TERI to undertake a component of the project—energy audit and dissemination activities—in Belgaum and Coimbatore foundry clusters. TERI conducted energy audits in six foundry units in each cluster and also developed cluster-specific documents on best operating practices (BOP). In order to disseminate the results of the project and provide knowledge on energy audit instruments, energy savings measures, new EETs/ RETs and pollution control in foundry units, TERI, in collaboration with local industry associations, organized six training programs (three each in Coimbatore and Belgaum) for participants from local foundry units during July 2015. Separate programs were organized based on the melting technologies (induction furnace or cupola) deployed by the units. In all, about 250 participants attended the training programs.

Experts from TERI threw light on the major energy consuming areas in a foundry unit; analysis of energy bills; methodology of energy audits; common monitoring parameters; and the various energy audit instruments that are used for performance assessment of equipment. They emphasized the potential for energy conservation through adopting BOPs, noting that in a typical induction furnace-based foundry unit, the melting furnace accounts for around 60–80% of total energy consumption. They also presented case studies on implementation of BOPs by foundry units in Kolhapur. Highlighting the importance of pollution control in foundry units, the TERI experts outlined the Indian emission standards for foundry units and explained the workings of several pollution control systems such as cyclone systems, venturi scrubber systems, etc. On the RE front, the participants were informed about the application of gasifier systems (a cost-effective as well as carbon neutral technology) for foundry units.

The training programs were followed by visits to foundry units that had undertaken energy efficiency improvements including implementation of BOPs, and to a unit where a gasifier has been installed.
