ENERGY AUDITS
Energy management is “The judicious and effective use of energy to maximize profits (minimize
costs) and enhance competitive positions” .It can also be defined as
“The strategy of adjusting
and optimizing energy, using systems and procedures so as to reduce energy requirements per
unit of output while holding constant or reducing total costs of producing the output from these
systems”
The first step in energy management is Energy Audit. Energy Audit is the key to a systematic
approach for decision-making in the area of energy management. This includes:
• Expenses-material, labour, energy
• Cost reduction, maintenance, productivity
• Conservation technology, energy mix
• Benchmark
• Technically and economically feasible
Need for Energy Audit:
The strategy of
adjusting and
optimizing energy,
using systems and
procedures so as
to reduce energy
requirements per
unit of output while
holding constant
or reducing total
costs of producing
the output from
these systems
In any industry, the three top operating expenses are often found to be energy (both electrical and
thermal), labour and materials. If one were to relate to themanageability of the cost or potential cost
savings in each of the above components,energy would invariably emerge as a top ranker, and thus
energy management function constitutes a strategic area for cost reduction. Energy Audit will help to
understand more about the ways energy and fuel are used in any industry, and help in identifying the
areas where waste can occur and where scope for improvement exists.
The Energy Audit would give a positive orientation to the energy cost reduction, preventive mainte-
nance and quality control programmes which are vital for production and utility activities.Such an audit
programme will help to keep focus on variations which occur in the energy costs, availability and
reliability of supply of energy, decide on appropriate energy mix, identify energy conservation
technologies, retrofit for energy conservation equipment etc.
In general, Energy Audit is the translation of conservation ideas into realities, by lending technically
feasible solutions with economic and other organizational considerations within a specified time frame.
Methodology
The energy audit will be initiated with a site visit on obtaining the W.O.
This will determine number of offsite and on site days required to
complete the work. This will entail visits of our auditors/ engineers with
required set of instruments. There will be continuous logging of energy
parameters to monitor load pattern over various cycles of day night
and weekends.
Generation of energy audit report will be through following methods or steps.
Step 1
Phase I –Pre Audit Phase
• Plan and organise
• Walk through Audit
• Informal Interview with
Energy Manager,
Production / Plan Manager
Step 2
Conduct of brief meeting
/awareness programme with
all divisional heads and
persons concerned (2-3 hrs.)
Step 3
Phase II –Audit Phase
• Primary data gathering,
Process Flow Diagram, &
Energy Utility Diagram
Step 3
Conduct survey and
monitoring
Step 5
Conduct of detailed trials
/experiments for selected
energy guzzlers
Step 6
Analysis of energy use
Step 7
Identification and development
of Energy Conservation
(ENCON) opportunities
Step 8
Cost benefit analysis
Step 9
Reporting & Presentation to
the Top Management
Step10
Phase III –Post Audit phase
• Implementation and
Follow-up
