A guide for energy savings.

Why does energy matter?
Everything you do has an impact - positive or negative - on the environment. That's the concept
behind your carbon footprint, which is one method of measuring the environmental effect
of our lifestyle. A carbon footprint, measured in tons, indicates the amount of carbon dioxide and other
greenhouse gasses that are produced as a result of your daily activities. The CO2 emissions of India in
2014 was 2,341,000 KT which has been steadily increasing since. Although efforts are being taken to
reduce the CO2 emissions the need for energy is restricting the process.
As the worldwide demand for energy rises, common energy-producing fossil fuels such as coal, oil, and
natural gas are being depleted, and the social, environmental and economic costs associated with
energy consumption are increasing. There are no easy solutions to the energy crises. Conservation,
Efficiency, and Renewables are the trio of practices that we can do to mitigate energy usage impact
and move ahead on the journey of sustainability. These energy-use practices along with energy
efficient building design using low-impact, long-lasting materials, programs for energy conservation,
and environmentally friendly practices reduce the negative environmental impact and contribute to a
green future.
Following are the most prominent effects on us:

1. Carbon Footprint
2. Water inadequacy
Water deficiency can lead to severe economic problems such as an increase in Global Conflict, Lack of
Access to Clean Water, Food Shortage, Economic Slowdown, and Energy Shortages. World energy
requirements are rapidly increasing with modernization and population growth, however, energy
production is one of the world’s greatest consumers of freshwater resources. Global electricity
demand is projected to grow 70% by the year 2035 with India and China accounting for half of the
growth. Alternative energy sources like wind and solar energy require far less water to produce but
only make up a small fraction of today’s energy production.
B. Effects on Nation
The most impressive effect energy efficiency can have is the reduction in the import of crude oil. India
is the fourth-largest consumer and net importer of crude oil and petroleum products in the world after
the United States, China, and Japan. India's petroleum product demand reached nearly 3.7 million
barrels per day (bbl/d), far above the country's roughly 1 million bbl/d of total liquids production. Net
oil import dependency rose from 43% in 1990 to an estimated 71% in 2012 to 80% in 2016.

The IEA defines energy security as “the uninterrupted availability of energy sources at an affordable
price”. Energy security has many dimensions: long-term energy security mainly deals with timely
investments to supply energy in line with economic developments and sustainable environmental
needs. Short-term energy security focuses on the ability of the energy system to react promptly to
sudden changes in the supply-demand balance. Lack of energy security is thus linked to the negative
economic and social impacts of either physical unavailability of energy or prices that are not
competitive or are overly volatile.
2. Energy Security
How can
we optimize our energy
consumption?
Contrary to the popular believe, there is quite a difference in Energy Conservation and Energy
Efficiency.
"Energy efficiency means using less energy for a
constant or regular service, while energy
conservation refers to reducing or going without a
service to save energy; sometimes finding
alternatives."
Although the most effective way to save energy would be conserving it, but many-a-times finding an
alternative to a service is not possible, nor is going without a service an option. In such case, the next
best thing to do is to use energy efficiently. Increasing energy efficiency often costs money up-front but
in many cases, this capital outlay will be paid back in the form of reduced energy costs within a short
time period. This makes efficiency improvements an attractive starting point for reducing carbon
emissions. Carbon emissions ultimately lead to carbon footprint, an emerging concept from the last
decade. The modern times demand attention to the amount of energy utilized as well as carbon
emissions realized due to daily activities; also measures to reduce the negative effects on the
environment.

Demand Control management is a very obvious strategy to help reduce demand so that appropriate
capacity can be provisioned to meet the demands. Improper demand management leads to improper
use of services and resources. Thus efficiency in such cases will be a far-fetched idea. Also,
unconstrained maximum demand in most cases could lead to high penalties. To analyze and get
optimized results of the demand, a better solution would be to use energy meters, that are, monitoring
devices to measure the relevant parameters. ESL's energy meters and EMS system provides an
excellent tool for energy data monitoring.
A. Demand
1. Demand Control
Demand response provides an opportunity for consumers to play a significant role in the
operation of the electric grid by reducing or shifting their electricity usage during peak periods in
response to time-based rates or other forms of financial incentives. Demand response programs
are being used by some electric system planners and operators as resource options for
balancing supply and demand. Such programs can lower the cost of electricity in wholesale
markets, and in turn, lead to lower retail rates. Such projects can be validated by our one time
audit service or by a continuous data feed EMS software.
Demand-Side Management (DSM) represents a revolutionary approach to planning at electric
utilities. Essentially, it broadens the scope of planning to integrate the customer's needs and
desires with the utility's goals. This process is used when demand is greater than supply over the
near term. The process is also used when actual orders are less than the demand plan over the
near term. Intelligent peak load controls are initialized and in accordance, the action is taken.
The electrical power used is transmitted synchronously to a utility measurement device. The
transmitted actual power is monitored by a microprocessor, controller, and continuously
compared with target values. Energy meters could be an effective tool to monitor the actual
transmitted power. Our marc.energy platform provides a solution which is not only optimized
but also hardware independent.

The ESCO model is basically a long term energy
management partnership. Energy services
companies (ESCOs) are increasingly involved, to
help industries save energy in their plants
& buildings. The total saving potential by involving
ESCO companies in EU is estimated at 84
MEUR annually (Danish Confederation of Industries)
Currently 25 out of 98 industries are planning or
implementing ESCO projects in public plants
& buildings. Being an ESCO, ESL is proudly
supporting industries pan India on their journey of
energy efficiency.

The term open access in terms of energy refers to the open bidding of the energy from all the available
market options. Consequently, the bidder with the least amount per unit is selected and cost
optimization is possible within the companies energy profile. Although a very tempting option, certain
parameters have to be thoroughly revised and reviewed for this. For example, the knowledge of energy
utilised daily in terms of KWh is to be obtained, along with certain factors like peak load time span,
power factor, total energy utilized by the products manufactured etc. Ultimately energy meters and
monitoring systems are a must for the management of open access energy utilisation and cost
reduction.

C. Renewable/ Schedule UI
1. Renewable source of energy
As the demand for the fossil fuels grew, the idea to tap energy from the alternative energy
sources continue to come, and solar energy in particular. For both, the consumer and the
environment this idea can and will be life-changing once solar energy is adopted
broadly. Today solar energy is used for various purposes like to generate power, to heat up
homes or heat water. By the end of 2015, only 55% of all rural households had access to
electricity and 85% of rural households depended on solid fuel for cooking. Solar products
have increasingly helped to meet rural needs.

Captive power plants are a form of distributed generation, generating power close to the source of use.
Distributed generation facilitates the high fuel efficiency along with minimizing losses associated with
the transmission of electricity from centralized power plants. Gas engines make ideal captive power
plants where there is a localized supply of gas.
Benefits of captive power plants are -
Security of power supplies through self-generation.
Reduced cost through high system efficiency.
Improved environmental performance.
2. Captive power generation
An analysis suggests that up to 21% of final energy demand and feed stock use in the
manufacturing industry sector could be of renewable origin by 2050, a five-fold increase over
current levels in absolute terms. This estimate is considerably higher than other recent global
scenario studies. In addition, if a 50% share of renewable in power generation is assumed, the
share of direct and indirect renewable energy use rises to 31% in 2050. Currently, only a tiny
fraction of solar energy is being used for industrial processes. Biomass-based fuels (“bio-fuels”)
have recently attracted a lot of attention for their potential to displace conventional transport
fuels. However, in the industrial sector modern biomass technologies such as biomass
gasification can contribute to achieving of the above-mentioned concerns.
By the end of 2015, a total of just under 1 million, solar lanterns had been sold in the country
thus reducing the need for kerosene. Today India is ranked number one in terms of solar
electricity production per watt installed, with an insolation of 1700 to 1900 kilowatt hours per
kilowatt peak (kWh/KWp).
Wind energy is another form of renewable energy which is available in abundant. In the year
2005, wind energy accounted for less than 1% of the total electricity production in the world. In
2008, it was estimated about 1-2% of the world ‘s energy supply comes from wind energy
source. As of 31 Aug 2016, the installed capacity of wind power in India was 27,676.55 MW,
mainly spread across South, West, and North regions.[6] This placed the India at this time as
the world's fourth-largest producer of wind power (behind 1. China, 2. USA and 3. Germany),
having overtaken Spain in 2015. Wind energy has seen huge potential in the last few years.
There is no doubt that more investment will be made in this renewable source of energy in the
years to come to fulfill the ever increasing demand for the electricity.

Monitoring power quality parameters for all critical loads are provided at the end of each month
during a contract period. These reports consist of energy-related data with a graphical illustration
of Transients, Sags, Swells, Voltage Dips, Harmonics, etc and an in depth analysis inclusing RCA and
CAPA for the caused events if any.
2. Power quality audit
Energy Management System is a monitoring system that monitors the energy consumption
and expense in an organization. It is a software that gives an organized report of any parameter
requested by the user with historical data, trends and patterns.
The steps followed are easy and can be human interfaced.
3. Energy Management System
The first step is to get an input from the on-site energy meters.
The next step is to induce the input in a platform and communicate with the EMS software.
The final step is observing the calculated reports and charts generated; and consequently take an
action to avoid energy leakages and misuse.
Methods to tackle high energy
consumption
Energy Audit is the key to a systematic approach for decision-making in the area of energy
management. It attempts to balance the total energy inputs with its use and serves to identify and
optimize all the energy streams in a facility.
The type of Energy Audit to be performed depends on:
1. Energy Audit
Function and type of industry.
Depth to which final audit is needed, and,
Potential and magnitude of cost reduction desired
Thus Energy Audit can be classified into the following two types.
Preliminary Audit
Detailed Audit
An energy audit at times can save up to 20% of energy with 6-7 months of ROI for energy intensive
plants and buildings.

Motors and motor driven equipment require around 80% of the total energy spend in an industry. Thus
motor maintaining is a very important part of any industrial energy preservation.
Conditioning is the process of monitoring a parameter of condition in any machinery. But for such the
motors need to be commissioned out of service and then proper maintenance scheme need to be
used. This results in equipment downtime and poor OEE . For such scenarios, ESL has come up with
a online predictive maintenance solution known as marc.motor.
Features of marc.motor
4. Health Assesment
marc.motor uses advanced processing algorithms to monitor the condition of the connected
equipment and then it compares itself with its own learned model.
It effectively allows the motor itself to act as a sensor.
During learning mode, MARC motors acquire real-time data from the motor and takes into account
all speed and load variations experienced.
In normal operation, MARC motors produce a series of new mathematical models of the system in
every 90 seconds.
And by comparing the parameters in this new model with those in the reference model, developing
faults can be accurately detected and diagnosed.
By combining advanced model-based fault detection and intelligent diagnostics, the system is able
to deliver outstanding results with minimal user intervention.

Depending on an organization's ability or inclination to handle the various requirements associated
with the reduction of energy consumption the energy contract can be signed which results in
deployment and participation of an Internal Energy Auditor from ESL.
ESL energy outsourcing services includes:
5. Outsourced Energy Management
Information and analysis regarding the structure of the plant and its energy parameters.
Initial energy diagnosis and identification of overall energy utilization, using procedures of the
complete energy audit and creating a baseline of the project.
Creating energy objective definitions and drafting the energy goals as well as the benchmarks.
Development and management of action plan to accomplish energy objectives (includes
composition, with M&V methodologies, and documentation of the results obtained)
Periodic reports about energy consumption and power quality.
