Energy Audit Report
INDO GERMAN ENERGY PROGRAMME
ATAR SINGH Dy. Director NPTI
2
  • The following contents were considered for
    statistical analysis of the energy audit report
  • Energy audit draft notification
  • Energy audit reports Recent energy audit reports
    were collected from the power plants with the
    help from CEA. The plants who provided the
    reports are given in the following table
  • The scope of energy audit reports submitted also
    vary from plant to plant

3
  • For the analysis of the reports the following
    criteria was used
  • Segregation of report as per the energy audit
    guide lines
  • Equipment segregation list the equipment /
    sections segregated (refer the energy audit
    analysis sheet)
  • Methodology Initially the reports were seen for
    the equipment and its sub sections coverage and
    subsections.

4
  • For systematic analysis of the report, the
    contents were sub grouped in the following
    sections
  • Report title and cover sheet
  • Ref Code
  • Auditor code
  • Report title
  • Client Name
  • Location plant
  • Date of report
  • Auditor Name
  • Table of contents
  • Coverage
  • Executive summary (ES)
  • Company profile -ES
  • Objective /goals ES
  • Brief Summary -ES
  • Summary table ES
  • Classification ES

5
  • Description and energy consumption pattern
  • Introduction - Plant details
  • Audit team
  • Energy consumption cost pattern
  • Heat rates, efficiency
  • Production/Generation pattern
  • Process details
  • Equipment Coverage
  • Boilers
  • Turbines
  • Condensers
  • Cooling water cooling tower
  • Cooling water pumps
  • BFW pumps
  • CEP pumps
  • Other pumps
  • Compressors
  • Fans

6
  • Auxiliary power consumption
  • Total consumption details
  • Break up of individual equipment
  • Comments on auxiliary power consumption
  • General
  • Energy management system
  • Policy
  • Monitoring system
  • Bench marking
  • Training
  • Strength and weakness of auditors
  • Energy savings
  • Description/back ground
  • Estimation of energy savings
  • Cost benefit analysis
  • Technical risks
  • Action plan/ implementation plan
  • M V protocol

7
In some places no audit dates
8
Executive summary provide basic content of
report. Many reports require Strengthening on
this account.
9
Energy Generation and energy consumption pattern
not mentioned properly .Also more than 60 report
do not give plant process details adequately.
10
Motors, Transformers, Insulation and air
conditioning section are not properly dealt with.
11
  • Boilers
  • Major components require the coverage of the
    boiler sections are -
  • 1) Description 2) Boiler Specification 3)
    Economizer Specification
  • 4) Air preheater Specifications 5) Combustion
    control Excess air
  • 5) HP LP Heater specifications 6) Coal
    Parameters design
  • 7) Coal Mill details and performance. 8) Heat
    balance/PG Test
  • 9) Feed water design 10) Soot blower
    specifications
  • 11) Operation of boiler and others 12) Steam
    parameters
  • 13) Fuel Side analysis 14) Efficiency Evaluation
  • 15) Energy balance 16) APH performance 17)
    Insulation
  • 18) Water side analysis and treatment 19)
    Reheaters including spray

12
Specifications need to be more elaborate.
Analysis should have energy balance, soot blower
operation , deareator, Water side analysis.
13
Specification part is inadequate. Also heat
balance or PG test or design details need to be
more elaborate.
14
The essential components required for audit are
LMTD, thermal load calculation, condenser vacuum
are not given adequate coverage.
