BASELINE ENERGY AUDIT
SCOPE OF WORK
 METHODOLOGY ADOPTED
 KEY ENABLERS FOR THE STUDY

Baseline Audit Scope of Work
Review of the energy consumption and production
data of last 5 years as per the data reported by the
industry to BEE. A copy of the reported data will be
provided by BEE to the agencies / firms.
Our Approach
Review of energy data for 5 years will be done
vis-à-vis MIS, annual reports, reports submitted to
MoP, ORT (CEA) reports etc.
Baseline Audit Scope of Work
Study the process of the entire plant considering a
gate-to-gate concept which would mention type &
quantity of energy sources consumed, self generated
energy sources, process technology, raw material,
product output and various variable factors which
affect the energy consumption significantly.
Our Approach
Based on considerable experiences in Thermal Power
Sector, our team would study the entire plant on a gateto-gate concept, based on flow diagrams such as Coal
Handling Plant (CHP), milling system, boiler systems,
turbine system, condenser system, draft system,
regenerative feed heating system, AHP, cooling towers,
HT auxiliaries like BFPs, FD & ID fans, Mills etc. LT
auxiliaries like air compressors, HVAC, lighting,
conveyors etc.
Baseline Audit Scope of Work
Identify major energy intensive processes, equipments
etc inside the plant boundary where more than 80% of
total energy consumption of the plant are accounted.
Efficiency evaluation and assessment of energy
performance of above major equipment.
Compare the performance data with design data or
PG report.
Our Approach
Main auxiliaries accounting for more than 80% of APC
will be established.
Energy performance of main equipment will be assessed
w.r.t. to technical specifications/ PG test values based on
operational data, recent records, onsite data etc.
As run performance will be compared with PG test
data/technical specifications/last post overhaul data in case
of very old plants
Baseline Audit Scope of Work
Observe and compile various Energy Conservation
(ENCON) options implemented by the plant for the last 3
years.
Evaluate the saving potential available in the plant
which would occur due to process change, efficiency
improvement, retrofitting or fine tuning of operational
parameters.
Our Approach
Plant inputs on ENCON options implemented will
be collected from plant people based on MIS reports,
annual reports, BEE National Energy Conservation
awards, data etc as relevant.
Energy savings potential will be brought out w.r.t.
various subsystems from margins w.r.t. PG values or
best practice norm values, vendor information.
Baseline Audit Scope of Work
Preparation of audit report containing the summary of
savings, investment required etc. the report should also
be discussed and accepted by the competent authority of
the industry.
Our Approach
The summarized ENCON options / Cost Benefits
will be discussed with management competent
authority.
Our Approach (Cont.)
Team composition is being finalized based on
project locations.
The team consists of:
 One Certified Energy Auditor
 Two Energy Engineers
 Two Project Associates
About 10 days of baseline audit is envisaged.
Team compositions are being firmed up given
prior commitments / logistics modalities.
Our Approach (Cont.)
There will be an opening meeting on Day 1 to
discuss the plans, mutual intros , team organization
and facilitation needed.
There will be a closing meeting on last day to
present the draft findings of team and soliciting
feedback on meetings
Key Enablers
Technical diary of the plant (Design data)
PG test data/OEM specifications of various equipment
Three annual reports, ORT reports, MIS reports etc.
Free access to UCB data, onsite data, Lab data (Coal/ ash
analysis, water quality, %O2 values etc.)
Access to past energy audit reports of the plant
Full time association of Energy Manager of the plant and
suitable O&M functionary.
Key Enablers (Cont.)
Decent Stay and local transport arrangements for
NPC team, at GOI rates since it is a MoP project,
moreover, NPC too is an institution under DIPP,
Ministry of Commerce and Industry, Government of
India.
All information will be kept confidential.
The study will commence only after approval of
DCs on a mutually agreeable dates
