The Institution of Engineers (India), Andhra Pradesh State Center in association with Energy Efficiency Services Limited, Vijayawada and Department of Electrical and Electronics Engineering, Velagapudi Ramakrishna Siddhartha Engineering College (Autonomous), Kanuru, Vijayawada organized the One-day Workshop on Energy Audit and Demand Side Management at Velagapudi Ramakrishna Siddhartha Engineering College (VRSEC), Vijayawada. Nearly 60 odd persons have participated in the above Workshop.

Er. S VS Phani Kumar Ch, Assistant Professor, Dept. of EEE, VR Siddhartha Engineering College (VRSEC) welcomed the gathering and invited the dignitaries on to the dais. To start the workshop, prayer song was sung by Ms. Manasa and other PG students of VRSEC

Dr. P. Kodhanda Rama Rao, FIE, Chairman, IEI, AP State Centre briefed regarding the membership and its importance to professionals and encouraged audience to be the members of IE India, and given few of the activities carried out by the Andhra Pradesh State Centre and their role in encouraging budding engineers. Then coming to the topic he briefed the importance of Demand Side Management (DSM) and Energy Audit.

Er. A. Ponna Rao, FIE, Retired Engineer, APGENCO highlighted the problems in power sector and treats. He gave few solutions where really the power sector is suffering and discussed some of the government policies and modify it them to build a strong power sector.

Er. DV SBV Sastry, MIE, Retired Engineer from APGENCO highlighted to limit the subsidized power to formers and to have some accountability so that the wastage of power can be reduced.

The Guest of Honour, Er. Karthikeyan A K, Deputy Manager, Energy Efficiency Services Ltd, Vijayawada said that Energy is Expensive and Efficiency not and said that the same will be discussed in the panel discussion.

Finally, the Chief Guest, Er. T V V Siva Rama Kumar, Deputy Executive Engineer, APGENCO, Dr. Narla Tata Rao Thermal Power Station, Ibrahimpatnam said that the Energy Efficiency is depend upon the changes in climate and the Govt. of India has set up a Ntional Mission of Climate change.

As a token of remembrance, Certificates of Excellence were given to the following :

a. Er. T VV Siva Rama Kumar by Dr. Jandhyala Shankar, Former Mayor of Vijayawada Municipal Corporation.
b. Er. Karthikeyan AK by Er. A Punna Rao, FIE, Senior Corporate Member of IEI
c. Dr. PV RL Narasimham, MIE by Er. M Kanta Rao, MIE, State Center Committee Member.
d. Dr. AV Ratna Prasad, FIE, Principal of VRSEC by Dr. P Kodanda Rama Rao, FIE, Chairman, IEI, AP State Center.

The Inaugural Function came to an end by tea break.

The Panel Discussion was started with the following :

Er. Karthikeyan A K, Deputy. Manager, EESL, Vijayawada explained the efforts made by the EESL in educating the formers and to use BLDC pump sets in their forms, and CMS street lighting systems and Ujjala scheme of the government as part of DSM. He future continued about the EESL Agriculture DSM carried by the to decrease the burden on DISCOMs. He explained the problems faced by the DISCOMs with subsidized i.e., free power to Agriculture sector. He gave some statistical data.

Agricultural Sector consumes ~ 18% of total electricity supplied. This burdens around 40,000 Cr INR per annum – equivalent to one fourth of India’s fiscal deficit. Electrical Distribution Company (DISCOM) are facing huge burden of revenue loss. Electricity supply is free or applicable tariff is very low.

Net Result à Inefficient Pump-sets (low efficiency Pump sets 20-30%) Inefficient use of electricity lead to water depletion Agriculture consumes 85% of all available freshwater resources, no regulation. Bureau of Energy Efficiency (BEE) has initiated Ag DSM programme in India to reduce the burden of shortage of electricity supply and financial burden on DISCOMs.

Er. T V V Siva Rama Kumar, Dy. Executive Engineer, APGENCO, Chief Guest discussed regarding the Energy audit and its Importance, DSM is the trust area where research is encouraged. DSM will be the key to have low power consumption at peak load demand and it will also decrease the power losses on the Generation Systems. He beliefed the importance of Energy Audit for any expansion and future analysis of power consumption. He highlighted regarding the energy audit. General tests for Auditing in a Thermal Power Plant.

General calculations for Auditing from periodical data of the Thermal Power Plant. Detailed Energy audit Approach. Implementation of Audit findings/Recommendations for improvements.

After a small break for lunch, the following Panel Speakers were discussed on the above subject.

Er. A V K Jagannadha Sarma started the DSM Measures
To encourage consumers to use energy more efficiently by modifying their electricity consumption patterns in terms of the time and extent of electricity demand. DSM measures help the Consumers to use electricity in a more efficient manner. DSM measures can supplement Supply side strategies to meet the Supply Demand Gap. In the Long-Run DSM would avoid or defer costly capacity additions by slowing the demand growth. DSM would be a cheaper option when compared to a adding Capacity addition. Then he discussed the DSM load patterns and briefed the Demand Response based Tariff and Tariff Incentive that are implemented in US and UK.

Dr. PV RL Narasimham & Dr. B Srinivasa Rao Application of Energy management to Audit Findings. Then they breifed the National Mission for Enhanced Energy Efficiency (NMEEE) which is one of the eight national missions with the objective of promoting innovative policy and regulatory regimes, financing mechanisms, and business models which not only create, but also sustain, markets for energy efficiency in a transparent manner with clear deliverables to be achieved in a time bound manner. Then they briefed the Ministry of Power (MoP) and Bureau of Energy Efficiency (BEE) was tasked to prepare the implementation plan for NMEEE. Policies and DSM implementation - case study. Then they discussed the Technological up-gradations include the introduction of Energy efficient pumps, energy efficient motors, Variable frequency drives, replacement with LED lighting system, BEE labeled appliances, Smart Soot blowing for boilers etc.

During the Valedictory session, Certificates of Excellence was given to Er. A VK Jagannadha Sarma by Dr. PV RL Narasimham, MIE and Er. A Punna Rao, FIE. Participation certificates were also distributed by the dignitaries of the workshop.
