1. ENERGY PLANNING AND AUDITING
Energy Planning is one of the most important components of
the energy management program.
2 major function of planning in energy management are:
1) A good plan can Protect from disruptions
2) Ensure continuous emphasis on energy management
through scheduled events (training, demonstration,
research projects)

2. ENERGY PLANNING
 Developing objectives, strategies, programs and action
plan items constitutes strategic planning for the energy
management.
 It provides the basis for resources such as funding and
personnel for implementation
 It Incorporates energy action planning into overall
strategic planning by the organization, and hence it
legitimates the program at top management level

in
Energy Planning

4. ENERGY MANAGEMENT
“The strategy of adjusting and optimizing energy, using
systems and procedures so as to reduce energy requirement
per unit of output while holding constant or reducing total
cost of producing the output from these systems”
Objectives:
 To achieve and maintain optimum energy procurement
and utilization, throughout the organization
 To minimize energy cost/waste without affecting
production and quality
 To minimize environmental effects

5. 1ST STEP IS TO FIND OUT HOW, WHEN AND WHERE
ENERGY IS BEING USED.

6. ENERGY AUDIT:
Determining the Organization's baseline energy use
and energy performance is only starting point of
Energy Audit.

7. ENERGY AUDIT :
 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 all the energy streams in a
facility.

8. NEED FOR ENERGY AUDIT
 3 major operating cost of industries : Energy, Labour and Material
Among them energy has the hugest potential for cost reduction
 Energy audit will help to understand more about the ways energy
is used in the industries, and help in identifying the areas where
waste can occur and where scope for improvement exists.
 In general, energy audit is the translation of conservation ideas
into realities, by evolving technically feasible solutions with
economic and other organizational considerations within
stipulated time frame.

9. TYPES OF ENERGY AUDIT:
 Preliminary Energy Audit
 Targeted Energy Audit
 Detailed Energy Audit

10. PRELIMINARY ENERGY AUDIT
Scope:
 Establish energy consumption (Sources, energy bills)
 Estimate the scope of energy savings
 Identify the most likely and easier areas for attention
 Identify immediate low cost improvements/savings
 Set up baseline or reference point for energy
consumptions
 Identify the areas for more detailed survey/measuremen

11. TARGETED ENERGY AUDIT
 Provide data and detailed analysis on specified
target projects.
 Followed by detailed survey of target subjects and
analysis of the energy flows and cost associated
with the targets.
 Final outcomes the recommendations regarding
actions to be taken.

12. DETAILED ENERGY AUDIT
 A comprehensive energy audit comprising of
energy use of all major equipment
 Includes detailed energy cost saving calculations
and project implementation costs.
 Energy balance is one of the key elements of
detailed energy audit
 It is based on an inventory of energy using system,
assumptions of current operating conditions,
measurements and calculation of energy use.

13. 3 PHASES OF DETAILED ENERGY AUDIT:
1 ) Pre Audit Phase:
2) Audit Phase
3) Post Audit Phase

14. 3 PHASES OF DETAILED ENERGY AUDIT
A ) Pre audit phase: Site Visit is a starting point
 Discuss with the site's senior management about the aims
of energy audit & indicate the information needed
 Analyze the major energy consumption data with the
relevant personnel
 Obtain the building, mechanical & electrical equipment
layout drawings

15. 1 ) PRE AUDIT PHASE:
Outcome of site visit should be:
 To finalize Energy audit team
 To know the expectation of management
 To identify the major energy consuming area/plant items
 To identify existing instrumentation and additional metering
required prior to audit
 To plan for audit with timeframe
 To collect macro data on plant energy resources, major
energy consuming equipment
 To build up awareness and support for detailed energy audit

16. 2) AUDIT PHASE
Information to be collected during the detail audit :
 Sources of energy supplies
 Energy cost and tariff data
 Generation and distribution of sit services
 Process and materials flow diagrams
 Material balance data
 Energy consumption by type of energy, by department, by
major process equipment, by end-use
 Potential for fuel substitution, process modifications
 Review of ongoing energy management and procedures &
energy awareness training programs

17. 2) AUDIT PHASE
Baseline data to be collected during detailed energy Audit:
 Quantity & type of raw materials
 Technology, process used and equipment used
 Capacity utilization
 Efficiencies
 Percentage rejection/reprocessing
 Quantities and types of waste
 Consumption of fuel, water, steam, electricity, compressed
air, cooling water, chilled water

18. ENERGY AUDIT REPORT:
 Executive Summary (management of energy audit facility, total and
highlight of each energy saving measures)
 Main Report ( General description of process/facility, graph/ table of
annual energy consumption , description of energy inputs and output by
major department/ process and evaluation of energy efficiency of each
step in the process, )
 Recommendation for energy conservation measures with cost calculation
and benefits along with expected payback on any capital investment)
 Conclusion (specific recommendation for detailed engineering studies &
feasibility analysis to justify the implementation of energy conservation
measures that require high investment)

19. 3) POST AUDIT PHASE
Action plan should be prepared on completion of Energy
Audit.
List of Energy conservation Measures on priority basis
Suggest an overall implementation schedule
Monitoring ( collections and interpretation of data) shall result more
action and good practices should be replicated.
If gap between planned objectives and actual achievements is
large, reasons should be analyzed and new objectives, new actions
should be initiated and results should be monitored.

20. “ANALYSIS , ACTION AND MONITORING ARE A
CYCLIC PROCESS OF DETAILED ENERGY AUDIT.”
