Summary of EEOA-NV
Requi rements1
Eligibility of NV • Applied for planning permission on or after 1 Oct 2018
• Estimated annual energy consumption ≥ 54 TJ
(basis that business activity is carried out at full capacity, 24/7 365 days a year)
• Business activity of NV is carried out at a single site and from one of the following
industry sectors:
➢ Manufacturing and manufacturing-related services
➢ Supply of electricity, gas, steam, compressed air and chilled water for air-
conditioning
➢ Water supply and sewage and waste management
EEOA Requirement
for NV
• Develop EEOA plan
• Identify opportunities during Concept Engineering and Front-End Engineering Design
(FEED) stages along with cost-benefit analysis and GHG abatement potential
• Evaluate and incorporate feasible opportunities into final design
• Submit EEOA report to NEA/CMD for approval prior to Development Control (DC)
application
✓ Checklist and EEOA report clearance letter/email to be submitted at DC stage
Summary of EEOA-NV Requirements
Typical NV Development Lifecycle and Importance of EEOA-NV Requirement
EEOA-NV compels a more
structured framework and
rigour in identification and
evaluation of EEOs during the
design phase by
➢ Bringing people with right
expertise together to plan
for EE
➢ Challenging plant designs
with alternative options
Rat iona le fo r EEOA-NV2
Conventional Design Team & Process
Not Organised to Design for Energy Efficiency
1. Linear Planning
i. Owner & Engineering Consultant agree upon a design concept.
ii. After facility is built, Facility Manager tries to optimise energy use.
Pros Cons
• Quick and easy planning • Fail to account for downstream system-level
synergies
• Often too late to incorporate such synergies
after commencement of construction.
2. Energy efficiency typically not a facility design criterion
i. Not prioritised along with cost, schedule, quality and safety
ii. Design team’s main focus not on operational energy costs
• Identifies equipment that fits the budget.
Energy Efficiency Savings Potential
• Space constraint
• Disruption to production
• Additional cost of integrating
improvement into an existing
design

EEOA reports 2019-20 Average of energy savings
refinery, petrochemical, chemical,
manufacturing, biomedical, water
management, waste
management, power generation
sectors
11%
▪ Energy savings of NVs with one-time
EE improvement
▪ Range from 3% to as high as 31% EE
improvement
▪ Major energy savings due to
technology selection, heat recovery,
process/equipment optimization,
automation
EEOA for NV Results
- EEO Categories and Examples
Concept Phase• Various EE technologies
selected such as
process selection, types
of catalysts to be used
• Harness solar energy
• Implement IE4 motors
10 - 30%• Typical range of EE
improvement
• Usually gives large
savings but may require
high capital cost
Technology Selection
Concept / FEED Phase• Boilers with economizer
and air preheater
• Heat integration to
preheat cold streams
with hot streams
• Recovery of steam
condensate
Heat Recovery
15 - 30%• Reduce waste heat &
optimize resources
• Usually gives large
savings & reduces utility
usage
EEOA for NV Results
- EEO Categories and Examples
FEED Phase• Optimize process
parameters
• Eliminate/reduce
heating/cooling
requirements
• Select energy efficient
equipment
• Right sizing of equipment
2 - 15%• Low cost and quick wins
• Require operation staff
to agree
Process/Equipment optimization
Concept / FEED Phase• Automate batch
processes to increase
productivity
• Reduce energy loss due
to equipment idling &
heating/cooling
Automation
2 - 10%• Use EMIS & monitor
energy performances
• Long-term gains
Causes Leading to
Poor Qual i ty EEOA-NV4
Causes Leading to Poor Quality EEOA-NV
15
Insufficient management
presence and diversity
of expertise in EEOA
team
2
EEOA process
started after
design is finalized
defeats the
purpose and intent
of EEOA-NV
(retrospective
EEOA)
1 Over reliance on energy
consultants to perform
the EEOA
3
Insufficient brainstorming
for new and innovative
ideas
4
Mindset of capital cost
savings over energy
conservation
6
Lack of understanding of
best available and
emerging energy efficient
technologies/equipment
5
Equipment overdesign
which may lead to
equipment operating at
sub-optimal conditions.

Ingred ients fo r a
Good Qual i ty EEOA-NV5
Ingredients for a Good Quality EEOA-NV
Benefits of EEOA NV include reducing:
a) Capital cost of systems due to right sizing
b) Operating cost due to lower energy use
c) Maintenance cost due to operating at optimal loadings
Start earlyStart the EEOA process early (Concept stage) and
engage NEA Verification Office.
Right mix of EEOA teamForm a multi-disciplinary EEOA team with the right mix of
technical competency to work together to conduct a
meaningful EEOA ➢ e.g. senior management, project management, business
analyst, procurement personnel, design consultants, facility
designers, energy consultants, technical, operation and
maintenance personnel, equipment suppliers, academia etc.
Identify energy consuming systemsEstimate annual energy consumption (AEC) of the NV
based on guidelines and identify major energy consuming
systems (ECS) to be included in EEOA-NV.
Ingredients for a Good Quality EEOA-NV
18
Energy efficiency goes beyond EEOA NV and measuring energy performance is important as it will
a) Shift & reduce demand based on data
b) Benchmark key ECS
c) Understand where wastages are
Brainstorm togetherBrainstorm for innovative Energy Efficiency Opportunities
(EEOs) (e.g. energy conservation, energy efficiency, best
available technologies, emerging technologies etc.)
Quantify savingsQuantify energy savings, GHG emissions reduction, capital
cost, operating cost savings and payback period for EEOs
identified.
Incorporate monitoring of energy
performanceDesign facility to include instruments for monitoring of
energy performance of ECS (e.g. EMIS)
