4th DSM Interaction Forum Meeting ( 29th April 2010 )
Interested Participants should Register Themselves Below



Dear All,
We would like to thank you for the active participation during the past DSM Interaction Meetings.

We are pleased to invite you for the 4th meeting of DSM Interaction Forum. During this meeting we will benefit from expert views by Shri V. L. Sonavane, Member MERC, who has kindly consented to deliver the talk on ‘Demand-side management in the context of efficient distribution network’. This topic is of great importance in order to integrate the DSM implementation options with the feeder and sub-distribution network upgrades.

The talk is scheduled on Thursday, 29th April 2010 from 4.30 pm to 6.00 pm at the MERC Office, The World Trade Centre, Centre 1 - 13th Floor. You are requested to send confirmation of your participation in this meeting by sending an email to any of the following email ids:

Shital Khiraiya (

We look forward to a lively session on Thursday – 29 April 2010.


Presentation Abstract

Demand-side management (DSM) is an identified resource in the power sector planning with efforts of several institutions and provision of legal mandate of the Energy Conservation Act 2001. DSM supports environmentally benign interventions related to either shifting the load to low-carbon technologies and/or promotion of strategic conservation through the implementation of labelled products. Monitored and verified savings through the implementation of DSM interventions has always been contested by policy makers, specifically when interventions are made in a dispersed manner. Methodologies to hardwire the savings are now available and spatially dispersed DSM interventions are already under implementation, specifically in certain states such as Maharashtra, Delhi, Kerala and Karnataka. While the dispersed technology-based DSM interventions are implemented, feeder-based implementation approaches have clear benefits from the perspective of a distribution sector engineer. This presentation highlights the possibilities of feeder-based DSM implementation, where clear energy reduction (conservation), demand reduction and load shifting are feasible. Proposed approach supports initiation of DSM measures on certain feeders where DSM implementation can either defer or offset investments in the sub-distribution network. DSM interventions can also immensely benefit from the existing metering infrastructure, data monitoring and automation and smart metering. This process can also assist in monetizing the benefits of DSM by comparing pre and post-implementation load profiles. Such interventions can be implemented in various types of feeder profiles including commercial buildings, housing societies, mixed-use communities, industrial pockets and agriculture sector. The presentation targets discussions on merits and challenges of feeder-based implementation options. A roadmap to implement such options will be discussed too.

MERC Organizes workshop titled "Efficiency and Load Shifting Opportunities in HVAC Systems" conducted on 18 December 2009

Recognizing the importance of the Heating, Ventilation and Air-Conditioning (HVAC) end-use in commercial, public, industrial and residential sectors in the state, Maharashtra Electricity Regulatory Commission (MERC) had advised the distribution licensees in Mumbai to organize a Consultation Workshop. The Consultation Workshop was jointly organized by Tata Power Company, Reliance Infrastructure and BEST Undertaking with support from MERC. The purpose of the workshop was to deliberate on challenges faced in improving energy efficiency and load shifting, discuss market and technology perspectives and learn from exemplary case studies.

The workshop was attended by 150 participants comprising of consumers of utilities in Mumbai and Thane, utility representatives and MERC officials. Consumers from Mumbai included large energy users such as banks, hospitals, builders and developers, aviation catering services, telecom industry, airports authorities, SMEs, shopping malls, petroleum, refineries and chemical industries. The participants also included over 15 eminent speakers from the HVAC industry. Several topics including the opportunities in central systems, thermal storage technologies and case studies, opportunities in home appliances (air-conditioners, refrigerators and fans) and innovations in the waste heat recovery, solar systems and variable refrigerant flow systems were discussed.

The workshop participants benefited from the keynote address delivered by Mr. V. P. Raja, Chairman MERC and a high-level panel discussion in a final session. Key points identified as action items and opportunities towards promotion of efficiency and load-shifting technologies in HVAC systems during the panel discussion include the following:

  • Tariff triggers promoting load shifting and energy efficiency can potentially be used as one of the interventions

  • Utilities could potentially develop project implementation mechanisms comprising design and engineering support to the consumers and targeted funds to finance HVAC interventions

  • Tariff-based interventions are necessary but not sufficient conditions to promote energy efficiency and load management; well documented case studies and pilots are important to push forward the efficiency agenda

  • Demand-side management programs need level-playing-field in terms of cost recovery for stakeholders; it is important to think of "negawatts" similar to "megawatts" added in the system

  • Interventions in retrofits and changing footprints of the new stock to be added are equally important. MERC shall drive the process of supporting BEE-managed Energy Conservation Building Codes (ECBC) by integrating the efficiency agenda in the policy-making process of the Urban Development Department (UDD) and municipalities in Maharashtra. MERC shall organize similar workshop inviting UDD, GoM and municipalities.

  • Utilities have an opportunity and responsibility to provide Design Audit (also referred as blue-print audits) to ensure new stock to be added in the system use efficient HVAC systems and are designed based on building envelop considerations

  • Creating Design Audit Cells within the utilities and integrating the design audit process as a part of load sanctioning by utilities is an opportunity

  • Availability of technologies and market players is evident; targeted programmatic interventions should be carried out by the utilities
