Energy Efficiency transformation for an oil refining company
Scope of EMS
▪
▪
▪
We are a National Oil
Company in south east
Asia with a refining
capacity of 1 MBD i.e.,
~1% of global refining
capacity
Performance
▪
▪
▪
Identify EE initiatives to reach best-in-class performance
Implement 3 operational improvement initiatives as Value Accelerators
Set up implementation for 2 Capex Initiatives
Process
For a refinery, energy
cost forms ~60% of
operating cost, hence
the opportunity for EE
is immense
▪
▪
▪
Set up Energy
Management System
(EMS)
Improve equipment readiness to support
energy efficiency
Identify and cascade energy KPIs and
KAIs from GM to Operators
Implement performance monitoring and
dialogues system
People
▪
▪
▪
Build capability to sustain program
Codify technical and non-technical aspects of project in ‘EMS Brick’
Set up frontline engagement system

Overall
▪
Different energy practices
across all sites
▪
Standardized energy management
system across all sites
Performance
▪
Year and year incremental
improvement target
▪
4 year target to reach top
quartile performance
▪
Distributed initiatives not clearly
linked to meet target
▪
Consolidated initiatives to meet
target
▪
Energy KPIs for selected
functions only e.g., production,
engineering
▪
Energy KPIs for all energy
related functions incl.
maintenance, procurement
▪
Energy discussed only in
selected meeting e.g.,
hydrocarbon meeting
▪
Energy discussed in all crucial
meetings e.g., operations
meeting, reliability meeting
▪
No specific training on energy
efficiency
▪
Comprehensive capability
building toolkit incl. 22 modules
▪
Only 1 unit level energy
competition
▪
3 different energy competitions
at individual and group levels

However, there are some challenges that we faced in rolling out EMS
Issue
How it was addressed
Adherence to
new processes
and procedures
▪
▪
▪
▪
Communication cascade about the program and what
each member is required to do
Coaching through 3 bootcamps to ensure employees feel
confident that they can implement change
Role modeling by senior management to get involved in
project
Formal mechanisms such as KPIs
Ownership in
senior
management
▪
In monthly steering committee meetings refinery General
Managers presented the progress of EMS in their
refineries, which put them under pressure to show
progress
Roll out to
other refineries
▪
Pull forward program – training sessions conducted by
change agents of the pilot sites for change agents from
other sites
