INTRODUCTION
IIT Bombay jointly organized a workshop on demand side management and demand response in
collaboration with Shakti Sustainable Energy Foundation and Energy Management Centre,
Kerala on 1st August 2015. A representative group of 30 experts and officials from state
electricity regulatory bodies, utilities, energy management center, ESCOs and academia have
participated in the workshop. The program is divided into three sessions:
a. Session 1: DSM and DR activities in India- Scope, Potential and Implications
b. Session 2: Case Studies: Implementation Agencies and Consultant Experience
c. Session 3: Discussion on Potential and Programmes to Foster Demand Response in India
The workshop was inaugurated by Dr. R V G Menon, Vice Chairman of Energy Management
Centre, Kerala. He gave a brief introductory talk about the centre and the undergoing research
activities and shared his experiences in energy conservation. Dr. Dharesan Unnithan, Director of
Energy Management Centre (EMC), Kerala also added the activities in Kerala in this space. He

briefly described the DELP scheme which will be implemented in Kerala, in which every
consumer would get LED bulbs (2 each). He also mentioned briefly about the guidelines issued
by Kerala government on roof top solar PV.
Prof. Rangan Banerjee, Head, Department of energy Science & Engineering, IIT Bombay
mentioned the key objectives of the DR project in which IIT Bombay is currently involved with
support from Shakti Sustainable Energy Foundation, New Delhi. He enumerated the benefits of
demand side management and demand response which can play a vital role in energy
conservation and peak load management in Kerala.
Ms. Vrinda Sarda gave a brief introduction about Shakti Sustainable Energy Foundation (SSEF)
and its activities. She mentioned that SSEF has been active in the space of clean energy for a
period close to six years now and works collaboratively with national, state and local decision-
makers to craft sound energy policies to build new energy economy. Over the past six years,
SSEF has done many projects at national and state level on designing programs which can mark
the transition to MW scale in DSM implementation in India.

Session 1: DSM and DR activities in India- Scope, Potential and Implications Moderator: Dr. Dharesan Unnithan, Energy Management Centre, Kerala.
Speakers:
Smt. Sudha Kumari, KSEB Ltd.
Prof. Rangan Banerjee, IIT Bombay
Prof. Suryanarayana Doolla, IIT Bombay.
Smt. Sudha Kumari (KSEBL)
Smt. Sudha Kumari is with the Kerala State Electricity Board.
Summary of her presentation is outlined below:
Power crisis have been a major issue for Kerala. There is a wide
gap between the supply and demand of electricity in Kerala. Only,
30% supply of electricity is through internal generation (within
the state) while the rest of 70% is purchased from outside Kerala
at higher price. She mentioned that an Energy Savings
Coordination (ESCO) team, by the Kerala State Electricity Board (KSEB) was formed to
coordinate its energy conservation activities, in 2014. The team conducted energy audits for
consumers and advice consumers on energy conservation measures so that they can reduce their
power bills.
KSEBL is very active in DSM space, some important programs/activities are given below:
For creating awareness brochures, leaflets, poster etc. were distributed to all the
consumers.
Labha Prabha Programme: The scheme was launched as part of promotion of energy
conservation practices among domestic consumers. It offer cash incentives and a number
of other prizes. The KSEB also guide the consumers to participate in the drive and
provide information on how to reduce energy consumption.
6 | P a g e
DELP Scheme: 9 Watt LED bulbs 2 each were distributed to each customer (approx.75
lakhs) of KSEB. This program will be executed by EESL in collaboration with EMC,
Kerala.
LED street lighting project in Alappuzuha Municipality, in collaboration with EESL.
Energy Auditing for Hospitals, Government Institutions, KSEB buildings/ substation by
BEE certified Energy Auditors and Energy Managers.
Prof. Rangan Banerjee (IIT Bombay)
Prof. Rangan Banerjee is the Forbes Marshall Chair Professor in the
Department of Energy Science and Engineering, IIT Bombay.
Summary of his presentation is outlined below:
The goal of energy sector is to supply energy to all consumers 24/7
which can improve the quality of life. But supplying 24/7 electricity
at affordable prices is very challenging task. DSM/ DR can play a
major role in this solution. He mentioned that demand response includes all the intentional
electricity consumption pattern modifications by end use customers that are intended to alter the
timing, level of instantaneous demand or total electricity consumption.
DR program is classified into several segments including incentive based program and price
based program:
In incentive based program, customers get rewards for giving DR provider some level of
control over the customer’s electricity using equipment. These incentive based programs
can be classified into:
Direct Load Control – Customers receive payments for giving DR provider some
level of control over customer electricity equipment.
Emergency Demand Response Program - Customers receive incentive payments
for demand reductions to maintain reliability.
Capacity Market Programs - Customers receive incentive payments for providing
load reductions as substitutes for a system capacity.
7 | P a g e
Curtailable Programs - Customers get discounted rate for reducing load on request.
Ancillary Service Market Program - - Customers receive incentive payments from
grid operator for promising to curb electric loads when needed.
In the case of price based program(s), the customers are encouraged to curb the demand
based on the price of electricity. Customers who enroll themselves in this program can
save electricity by adjusting their consumption to lower-price periods. DR Price Program
can be classified into the time of use, real time pricing and critical peak pricing.
He presented the details of survey conducted by FERC (Federal Energy Regulatory Commission)
in 2009 to determine the potential of Demand Response in US. The survey showed that if DR is
implemented then by 2019 there can be significant reduction in the peak demand (around
188GW) 20% of current peak demand of US. He emphasized that such studies give a good
understanding of DR potential and help in planning and execution.
During the presentation there was a brief discussion on Kerala sectoral consumption pattern. For
the FY 2012-13, the electricity consumption in residential sector consumption is about 50% and
industrial sector is 30% followed by commercial sector (13%). The monthly load profile of
Kerala indicates a wide gap between the supply and demand. The load profile 28th July 2015 was
presented indicating possibilities of DSM and DR.
Sector wise DSM/DR possibilities suitable for Kerala state are discussed, which include:
Room Air Conditioners- Residential, Commercial
Central Air Conditioning- Commercial
Cool Storage –AC- Commercial
Water Pumping
Lighting- dimming
Industrial Process loads- scheduling, storage

Prof. Suryanarayana Doolla (IIT Bombay)
He is currently associate professor at the Department of Energy
Science and Engineering, IIT Bombay. Summary of his presentation
is outlined below:
Demand Response consists of three main components: Infrastructure,
Monitoring and verification, Pricing/ Incentives/ markets. DR
infrastructure consists of smart meters, communication network,
direct load controllers, meter management systems, automated meter
infrastructure (AMI), demand response automation system (DRAS),
Gateways, Routers and other IT related components.
The importance of each of these infrastructure components is discussed in detail and he
emphasized that demand response is not a product based program. It is a solution based program.
He briefly mentioned the DR execution process and interlinking of all these infrastructure
components. More emphasis was given on integration of Meter Data Management System
(MDMS) interface, where the entire consumer’s meter data are integrated with each site along
with other automation systems to execute DR.
He then discussed challenges various technical challenges utility would face during execution of
a DR project:
Interoperability challenges- Integrating MDMS with DRAS server
Handling bulk data between DRAS and gateways
Load Segregation challenges
Internet availability at customer site
Power backup for the gateways
Integration of manually controlled Loads
Regulatory policies
He highlighted the role of monitoring and verification in success of DR program. Various
baselining techniques were discussed in detail. He also highlighted large scale demand response
pilot executed by Tata Power, Delhi.

Discussion:
The presentations were followed by a discussion session. The key elements of discussions are
detailed below:
Suresh Kumar S (KSEB) mentioned that KSEB can put restrictions in the load usage rather than
making customers to do so. They can make some arrangement within the system which can bring
down the load usage pattern. He also expressed his idea of DR implementation in residential
sector in Kerala?
Prof. Rangan Banerjee explained that Kerala majority of electricity is consumed by residential
consumers. DR program in residential sector may be an unviable option considering the
complexity and costs involved.
For residential sector, voluntary options are better than mandatory programs. Residential
sector implementation will account more cost with less benefits. In case of Kerala, DSM
through energy conservation may be a good fit.
The commercial and industrial sector should be focused for DR related activities as they
would be a very good starting point. If DR program is implemented in commercial and
industrial sector without affecting the production, benefit can be seen easily.
Based on purchase of power decisions should be taken.
It is important to have a strategic plan for implementation of DR programs.
Transaction cost for small scale consumers is very high.
Dr. Arvind M T (Ample bit) added that if DR implementation is done, monitoring and
verification is very important (as mentioned by Prof. Doolla), which cannot be possible in
residential sector.
If effective results are required then focusing on high end consumers is very vital choice
as they are in limited number and the implementation as well as M & V can be done. He
also suggested that for Residential Consumers TOD pricing can be done which can be
more amenable.
10 | P a g e
Suresh Kumar S (KSEB) raised one more question about the managing the load demand in peak
hours which is from 6 pm to 9 pm as for now during this time to meet the demand KSEB is
purchasing power from the neighboring state(s).
Prof. Rangan Banerjee explained the importance of load profile of Kerala for such activities. The
base load is mainly due to the industrial and commercial sector.
If load shifting, load curtailment is done by these sectors as they are flexible, it can make
a huge difference in the load profile.
It is possible to achieve 10 to 15% of reduction easily.
Rather than buying power from the neighboring states if that money is used as incentives
to the high end customers, the DR program can play a major role in energy conservation.
Initially some pilots program should be carried out which will give a brief idea about the
scenario of Kerala in terms of DR.
There was a question about economic viability of DR program conducted by Tata Power Delhi.
Prof. Suryanarayana Doolla informed that this pilot project would serve as a proof of concept for
technology deployment and economics were not worked out at this point of time.

Session 2: Case Studies: Implementation Agencies and Consultant Experience Moderator: Prof. Rangan Banerjee, IIT Bombay
Speakers:
Mr. Ritesh Yadav, ICFI, New Delhi
Dr. Arvind M T, Amplebit Energy, Bengaluru
Dr. Mahesh Patankar, MP Ensystem, Mumbai
Mr. Neeraj Kaul, INNOVARI, Gurgaon
Mr. Ritesh Yadav, ICFI, New Delhi
Summary of his presentation is outlined below:
ICFI conducted a pilot project of design and implementation of large
scale demand side bidding in Rajasthan with help of SSEF and JVVNL
Rajasthan. Introductory meetings were held with the key officials of the
Jaipur Discom and the state energy department. Workshops and capacity
building programs were conducted for the utilities and stake holders.
Chairman, Discom appointed RDPPC as the nodal agency for roll out of
the pilot project.
Approach:
Steel Industries were selected for the pilot project, 25 Industries from three Industrial
areas in Jaipur. Load research study was conducted to ascertain DR potential for these
industries. High 5 of 10 days was selected as baseline methodology. A total of four 4 DR
events were carried out of 1 hour duration. An incentive of Rs. 2.5/kWh was paid to the
consumers. SSEF funded this project.
12 | P a g e
For implementing the project, GPRS enabled modems were installed at all consumer
premises. Login ID and passwords were given to each consumer. The validation was
done by CMRI data from JVVNL.
The bid submission process was by M/s AMP Solutions to India Energy Exchange (IEX).
IEX after clearing the bids sent the results to JVVNL. In this program, customers were
notified 4 hours before the DR event by phone call or by SMS. The incentives were given
to each customer by cross checking the load portal.
Some important takeaway(s) from this project:
DR should be called when over drawl is expected.
Frequency Monitoring should be done, DR to be called off if frequency is high.
Weather monitoring should be continuous, in case demand drops due to sudden change in
weather the DR can be called off.
Dr. Arvind M T, Amplebit Energy, Bengaluru
Summary of his presentation is outlined below:
Dr. Arvind demonstrated a dashboard interface for AC unit of their
customer. He mentioned that customers are motivated to invest in
DSM measures only if they see reduction in energy cost. Other
reasons are secondary to them. However, customers do appreciate
transparency in measurement, reporting and baselining. Access to a
lot of data and analytics is generally appreciated by the customers.
Customers may not be electrical engineers but they have
sound business sense and are aware of the patterns of their
load.
They have a pulse of how it works and how it is changed.
Customers are always willing to participate if a system is designed and that meets their
requirements and the baselining and measurement issues are approached properly.
Complex strategies for baselining and savings computation discourage customers and IPMVP
methods of curve fitting are not really appreciated by them. There is also a lot of scepticism
13 | P a g e
about ESCOs and use of subjective criteria by them to calculate savings have caused loss of
respect among customers.
The experience of Amplebit with private utilities in Mumbai has been good and encouraging.
With government utilities, not just in Mumbai but in other parts of the country too, the
experience has been in the order of neutral to disinterest to opposition.
Some of the government utilities believe that DSM is an occupational hazard which is
imposed on them by policies and regulations.
DSM is relevant especially in Indian context as there is supply-demand gap at a national
level. Although at state level, arguments for not participating in DSM may be different
but for a national interest, DSM should be given appropriate importance.
It is neither considered important nor something that is required. There are utilities that
believe that DSM measures work only with big customers and hence implementing DSM
will cut that revenue for them.
During the meetings conducted with regulators and utilities, it was suggested that DSM
should be practiced in agriculture sector as the power there is either free or subsidised.
The need for DSM can be articulated in a simple economical fashion to the customers
stressing the fact that DSM would lead to financial savings, the path to implementation
can become easier.
Some customers argue that power factor control has been implemented as a DSM measure, and
there is not much to do in that space.
The reason for such an argument comes from the fact that the effect of power factor
control is evident on the tariff bill, there is always a strong reason to practice it as there is
penalty if not done and incentive if done.
The effect of most DSM measures does not translate to incentive or penalty on the bill,
and it is one of the major reasons why DSM has taken a backseat in the country.
Kerala and Madhya Pradesh have done this to an extent by way of introducing
differential tariff through TOD structure and penalty for certain higher consumption
which acts as both carrot and stick.
There is strong need for this carrot and stick policy to be implemented in DSM context.
14 | P a g e
There is presence of appropriate DSM technology in the country and those are not difficult to
implement. Even the cost is economical and shouldn’t be a constraint.
It has been proposed to regulators and utilities that the first way to encourage customers
to implement any DSM measure is to provide them with data about their consumption
pattern.
Implementing such strategies through utilities is not a great idea, as a lot of capex
allocation and tendering process are involved.
Third parties can be encouraged to deploy cost effective simple technologies at customer
location that can enable data about different sections of the load accessible to customers
at all times.
This can help customers make decisions regarding if DSM is good for them. Moreover, if
the top 20 % of the customers are consuming, say 60-70% of the total energy consumed,
educating that 20 % section of the customers will fulfil most of the objectives.
Amplebit has a lot of customer data and case studies that can be shared on the public domain and
it is believed that information about DSM technologies and analytics on what can be done when
coupled with IT solutions can benefit the cause in a big way.
Dr. Mahesh Patankar, MP Ensystem, Mumbai
Summary of his presentation is outlined below:
DSM consists of two major DSM consists of two major
components: Demand Response (DR) [part of load
management] and Energy Efficiency (EE), which is
considered as conservation.
Demand response programs involve voluntary load
curtailment by the customers in response to the trigger
signal from the utility. For the amount of load reduced, the
consumer is either incentivized or penalized.
15 | P a g e
Tata Power Demand Response Program was approved by MERC.
The program was designed to involve customers during high cost power purchase and
transmission/distribution network constraints.
It consists of 100 hours in a year in which each event was of 2 hours.
The enrolled customers were paid per 2.5 KWh of verified load curtailment.
Baseline established as High 4 of 5 days excluding weekdays, holidays and prior event
days.
A significant load reduction was obtained such as in pumping operation and AC
operation.
Maharashtra’s draft M&V regulations cover impact, process and market effect evaluations.
The Impact evaluation details actual demand and energy savings of DSM programs and
process evaluation tries to evaluate the procedure adopted for execution of DSM
programs.
It also covered the strategies that worked or failed during the implementation. The idea is
to promote these strategies as guidelines for implementation of DSM programs in future.
Market effect evaluations tries to articulate the effect of program implementation on
market performance.
Free rider and spill-over effect is also looked at as a part of these evaluations. These
evaluations, thus, look at DSM implementation in all three dimensions.
Mr. Neeraj Kaul, INNOVARI, Gurgaon
Summary of his presentation is outlined below:
The key elements of his presentation are detailed below:
Innovari carried out projects with Reliance, CSE, and TPDL. With RInfra
(Mumbai), M/s Innovari conducted a pilot project of 1MW in hotels
16 | P a g e
malls and other commercial sector with no incentives. Shadow meters were installed at the
customer side. The set point of AC systems were raised by 0.50. The load reduction was seen in 1
hour only.
Innovari adapts agent based automation solution. He explained importance of this mechanism
and discussed in details role and responsibilities of various components in this agent based
automation system. He also explained about interactive energy platform developed by Innovari
for their clients. This system seamlessly connects between hardware, software and
communication network to securely analyze, communicate and respond in real-time.
Finally, a responsibility matrix is created between INNOVARI and Utility for the DR planning
and execution process.
Discussion 2
The presentations were followed by a discussion session. The key elements of discussions are
detailed below
Does the regulation of Maharashtra allows giving or collecting any incentives from the
consumers? – Mr. Suresh Kumar S (KSEB)
Dr. Mahesh Patankar (MP Ensystem) answered that the rules and regulation for DR is covered
under Demand side regulation which allows incentives to be offered to the customers. But for
that Benefit cost analysis is must before the implementation of the program. Mr. Ritesh Yadav
(ICFI) added that the section 61 and 62 of electricity act 2009, allows differentiating consumer
on basis of their consumption pattern and specific use. Thus on basis of those Incentives can be
offered.
Mr. Neeraj Kaul (INNOVARI) mentioned that during CESE (West Bengal) project they faced
many challenges in implementing the program as people were not ready to integrate their loads.
So to overcome this first they educated the people then they integrated the loads on utility portal
platform. Since control is given to customers, they can manage the load reductions, thus can
know their benefits. They can even schedule the event base on their comfort.
17 | P a g e
Mr. Suresh Kumar S (KSEB) proposed to have a pilot project in the Kerala state for commercial
sector as the HT consumers can be approached and be requested for DSM program. He also
added that the designing of program should be started as soon as possible for sanction of project
from the regulatory.
Dr. Dharesan Unnithan (EMC) mentioned that in the state of Kerala people are using stabilizers
for each and every equipment. He raised question about how to reduce the usage of these
stabilizers. He also enquired about the thermal storage programs and the outcome of these
projects.
MR. Arvind M T (Amplebit Energy) suggested that with good quality of power and regulation of
voltage this wastage can be removed. Prof. Suryanarayana Doolla mentioned about the thermal
storage practices which were carried out in many commercial sectors by giving example of
National stock exchange which was very busiest sector in Mumbai. Thus, he suggested that
thermal storage can be cost effective if implemented in Kerala.
There was a question with regard to INNOVARI program- Automatic or Manual DR
Mr. Neeraj Kaul mentioned that the systems was automatic, Energy Agent was set up in the
customer premises in which sim card was installed for the operation of the events. Mr. Ritesh
Yadav and Dr. Mahesh Patankar mentioned that the projects they were handling (in Mumbai and
Rajasthan) were manual program the customers were informed by the phone call.
The issues with failure of modems was raise by Smt. Sudha Kumari (KSEB).
Mr. Neeraj Kaul mentioned that instead of one sim in the Energy agent two were installed for
emergency cases.
18 | P a g e
Discussion: Potential and Programmes to Foster Demand Response in India Moderator: Prof. Rangan Banerjee, IIT Bombay
In the discussion session, the main topics discussed include:
DR potential areas
DR strategies for Kerala.
Mohammed Zia (KSEB) mentioned that loads (profile) for different states are different,
depending on that DR programs scheme can be made.
In Kerala, the focus is mainly on Energy Conservation. There is a plan to facilitate each
and every consumer in the state with information on their electricity consumption and
suggest them various energy efficient measure. He opined that DR scheme can also be for
domestic consumers, for that KSEB is taking help from voluntary NGO’s and requested
SSEF to assist in this activity.
In Kerala state, the load curve of 2009 and 2010 are coinciding, which indicates that the
trend is almost constant with no rise.
KSEB is creating awareness as they want to empower their consumers and guide them.
For example: purchasing energy efficient bulbs. He also mentioned that they are trying to
bring manufactures and consumers at one platform so that energy efficient products are
only sold.
Prof. Rangan Banerjee (IIT Bombay) suggested to have a framework for DR. This would help in
monitoring the progress.
Dr. Dharesan Unnithan (EMC) informed that they conducted a study on star labelling program,
and found that about 40- 45% of products being purchased by the consumers were 5 star rating
products. EMC is giving more thrust on this aspect to encourage consumers to buy more efficient
products.
Mr. Premkumar (Renewable Agency) has expressed his concern with regard to high penetration
of renewable energy. Mr. Gopakumar (Consultant) suggested that HT consumers should be
19 | P a g e
accounted for the DR programs. He suggested that universities should also be taken into account
as they have good potential for DR programs.
Ms. Nisha Jose (BSNL) informed the participants that BSNL load is more or less constant and
hence they may not be able to participate in DR level activities. She mentioned that BSNL is
constantly putting effort to conserve energy (For ex. They switch off the UPS after office hours
and with help of timer they switch on in off peak hours when tariff is less). Mr. Arvind Tiwari
(Amplebit Energy) showed the telephone exchange data from MTNL. In these exchange offices
there is around 30 – 40 % peak in evening time and it’s not flat all the time. He also informed
that during morning time, the load is increased due to exchanges and also because of people
which can be reduced substantially. He mentioned that in exchange sector every floor is having
different packages AC which have different efficiency. This aspect may be looked at. Mr. Arvind
Tiwari added the infrastructure of the exchanges are very old that even for cooling 4 racks they
put high load on AC. Prof. Banerjee suggested that for such cases, DSM would be a better choice.
Mr. Ritesh Yadav (ICFI) suggested that since Kerala is a tourist destination in India, the hotel
industry could be an ideal choice for DR program, in the starting phase. It would better to target
energy efficient user and DR should be restrict to commercial and industrial sector in the initial
phase of the program.
Mohammed Zia (KSEB) suggested that cool storage is one important area for energy saving and
felt that a pilot project at large scale can be tried in this area. Dr. Mahesh Patankar (MP
Ensystem) recommended that tea industry is another are with high DR potential and he shared
information regarding to DR potential in tea industry in northern parts of the country.
Dr. Dharesan Unnithan(EMC) mentioned that EMC has done study on the sectors like on plastics
industry and commercial sectors. They are also having steel rollers but they faced problem as
steel industry are not participating, as some consumers are not keen on sharing their data. EMC
tried by offering free energy audit to these industries, but only one company expressed interest.
He also mentioned about fund earmarked by Kerala government for energy conservation
programs. This fund is primarily from Bureau of Energy Efficiency.
Dr. Mahesh Patankar (MP Ensystem) suggested that the funds can be used to hire architects for
designing upcoming buildings in commercial sectors, which can help in increasing the energy
20 | P a g e
efficiency from the base. Ms. Vrinda Sarda offered that they are ready to share the report of
designing the system.
Mr. Arvind Tiwari (Amplebit Energy) suggested that if electricity rates can be made steeper the
reduction can be seen. He also suggested to carry out monitoring of equipment’s which were
distributed, to know the feasibility of the program and check the progress rate. He added that
high consumers should be targeted first like hostels, malls, hospitals and university as these are
fertile for such activities and easily achievable. He also enquired about possibility of setting
minimum DR targets for some consumers through regulator. Dr. Dharesan Unnithan mentioned
that at present EMC is not authorized to do by the regulatory. He mentioned that KSEB is giving
20 units free to its commercial consumers as they are the revenue generating group of the state.
Ms. Vrinda Sarda (SSEF) opined that DSM could be part of power procurement process rather
than developing individual programs.
Mr. Ajith Kumar (Cochin Port Trust) suggested that DR can be implemented in their port area as
it includes about 21 HT (11kV) consumers and 900 LT consumers. There is a plan to add new
chiller plants in the cold storages and freezing units.
Prof Rangan Banerjee summarized the discussion during this workshop
There is a good scope for analysis and understanding of load variation.
There are suggestions and interest from the stakeholders with regard to pilot projects in
Kerala. that case studies should be done in Kerala.
SSEF and KSEB can jointly work to find out the potential areas of DSM as this is the
right time to implement DR programs.
Pilot programs can be carried out for commercial sector as they are of great potential
instead targeting residential sector first.
Other suggestions include engagement of regulatory commission, KSEB holding seminar
for industries, new stock design.
There is an inertia to move from kW to MW scale. It is important to aim at large scale
projects. It is possible to include universities for research, analysis and quantification of
DSM and DR potential and benefits.
