The Practical Steps & Key

Success Factors For Successful EPC Projects Implementation

The Key Steps

Confirm The Need!

Understanding on EPC concept by the building owner

The needs to adopt EPC model

Self assessment

Comparing energy benchmark

Estimation of project costs & saving potentials

Private investment & Risks transfer to ESCO - viable sharing ratio/%

Opened or Closed Tender?

Scope of Services under EPC

Project Funding & Financing Options

Engineering & Economic Feasibility Studies

Project Design, Engineering & Permitting

Project Construction

Project Commissioning

Operation, spare parts & Maintenance

Performance measurements & monitoring

Preparation

Facility Profile Basic building information

Floors & areas

M&E equipment & system data

Building materials information & data

Energy consumption

Define project & preliminary scope

Evaluation criteria ESCOs

EPC Project Proposals

Prequalification of ESCOs

Qualifying criteria

Own criteria must consider the nature of

ESCO business for EPC

Current criteria by ST is insufficient to

determine the financial & technical capabilities

of registered ESCOs

Identify Potential ESCOs

Selection of ESCOs

Experiences in EPC/Track Records in energy services

Financial Strengths

Management capacity in

energy services

Technical Competency &

Expertise

ESCO

To secure

financing & ensure

sustainable

operations

Issue Request for Proposal

Evaluation of Proposals

Example: Evaluation Score Sheet

Detailed Energy Audit

Investment Grade

Energy Audit

Scope & schedule

Findings

Energy saving

potentials analysis

Projected annual cash

flow

Measurement,

Monitoring &

Verification of actual

savings

EPC Contract Document

Drafted by JKR for government buildings as reference To be customized based on requirements of each building owner

Factors should be considered to reduce dispute in EPC Contract

Obligations of owners & ESCOs

Factors affecting savings performance

Valuating savings uncertainty

Minimum operating conditions

Energy prices/tariff rates

Verification by A third party

Baseline modification/review(non-routine)

Balancing uncertainty and costs

Protection from risks by both parties

Project Implementation

EPC Contract Negotiation &

Signing

Install permanent sub-meters

Collect energy data to

establish energy

baseline values

Improve & optimize energy

consumption with proposed

saving measures

Measure & monitor actual

energy savings achieved

against agreed baseline values

Measurement, Monitoring &

Verification

For actual savings achieved

Methodology/Protocol

Baselines agreed

Permanent metering (highly recommended)

Options For

Energy Baseline & Saving Calculation

Method Advantages Disadvantages

Utility billing history Low cost Effects of weather ,

occupancy, other

changes may mask

savings

May be unreliable

unless savings are

significant compared to

normal bill variation

Data already available

Independent data

Represent all effects of

ESMs

Account for interactive

effects

System/Equipment

sub-metering

Isolate effects of ESMs

Higher cost

Misses interactive

effects

Very accurate for

lighting measures

Results are more

predictable(low risk)

Baseline:

Baseline year from electricity bill data (kWh)

(kW

h)

Example:

Energy saving calculated by the difference between a

baseline year and a subsequent year from electricity bill

(kW

h)

Baseline : Building Monthly Load Profile (kW) from sub -metering

31

Baseline :

Building monthly electricity consumption profile(kWh) from sub -metering

32

Baseline :

Building monthly load profile(kW) for AHU from sub -metering

33

Baseline :

Monthly electricity consumption profile(kWh) for AHU from sub -metering

34

Example: Savings calculated based on actual

measurement from sub -meters

Modifying/Reviewing Baseline

To establish standards for changes which may reasonable expected to change energy consumption trend in the facility

Occupied square footage, operating hours

parameters other than the ESCO equipment

Energy equipment, other than ESCO equipment, that malfunctions, or is repaired, or replaced in a manner that increases or decreases energy consumption;

Other actions taken by the facility owner that may reduce or increase energy use; and,

Discovery of an error in the original baseline, in which case the change would be retroactive

Trust , good

relationship &

effective

communication

between ESCO &

building owner is

crucial to identify the

needs to

modify/review

baseline!
