The Bangladesh Industrial Energy
Efficiency Finance Program with the Asian
Development Bank (ADB), have established
methods to develop eligible energy
efficiency projects in SMEs. This program
focuses on six target industrial sectors that
show large savings potential in Bangladesh
(Limited, 2014).
In India some studies were taken
place to identify the potential for implement
efficient energies in the country. According
to them around 48% of the total energy
consumption of the industrial sector is used
by SMEs. It is estimated that SMEs’ energy
consumption can be reduced by more than
25% through energy conservation and
energy efficiency measures. Compared to
large companies, SMEs have an energy
saving potential that is about 15-20% higher
(Sanjoy Sanyal, 2016).
In accordance of many studies of Asian
as well as European countries, it has been
identified that there is a energy saving
potential in SMEs by enhancing the enrgy
efficiency in varoius ways and the study is
mainly based on those previous findings.
3 METHODOLOGY
The firms for energy audits were
selected with the information got from
literature review, in order to track the errors
in higher energy consuming sectors.

Table 1 represents the details of the
selected companies. Before conducting
energy audits their general information
160
about the energy consumption in specific
processes, energy consuming machineries
and energy cost of the firms from the
electricity bills were collected to track the
energy cost of the firms as a total annual
value. Then the energy audits were
conducted for three days and machineries,
processes have been measured with the help
of the loggers. Data were collected from the
audit and analyzed with the pre collected
data to identify the energy saving potential
as well as cost saving potential of the firms.
4 DATA COLLECTION AND
ANALYSIS
As mentioned above the electricity
bills for 12 months of the five SMEs
selected were collected as the primary data
to identify the behavior of their energy
consumption. Then the main energy
consumed sources were identified by an
initial visit to each company with the
knowledge of experts. Then the energy
audits were conducted in each company and
data were collected by connecting loggers.
With the pre collected data, annual
energy share of each company from
different energy sources is been identified
and graphed with the annual cost share of
the energy sources.
