Harmonisation Study
of Grid Codes and
Technical Standards
for ASEAN Power Grid

Tenaga Nasional Berhad
V
arious p ar ts of the
world have implemented
interconnection of national
grids. Such interconnections
are considered feasible
commercially and are successful
w hen c ommon p r ac tic es,
particularly for planning and
operating codes, commercial
arrangements for importing and
exporting power and certain
ancillar y ser vices. Success
also depends on institutional
arrangements, such as an
arrangement by power utilities
of the participating countries
being established. Technical
harmonisation of power grids
of the ASEAN Member States
(AMS) is therefore one of the prerequisites for interconnection
of AMS national power grids to
achieve the vision of the ASEAN
Power Grid (APG).
The Heads of ASEAN Power
Utilities Association (HAPUA),

with the assistance of the
Asian Development Bank (ADB),
have engaged consultants to
undertake a harmonisation study
for ASEAN power grids, including
making recommendations on
possible solutions for technical
harmonisation and barrier
alleviation. At the inception
meeting held in Jakar ta,
Indonesia in February 2013
national experts from nine AMS
and representatives from the
ADB were present to review the
scope of work, work schedule
and the terms of reference.
Valuable sug gestions and
comments were received from
APGCC, HAPUA Working Group
No. 2, ASEAN Centre of Energy
(ACE) and national experts
present at the inception meeting.
During the first phase of the
harmonisation study, valuable
data and information were
collected with the help of AMS

national experts. The project
recommends possible solutions
for technical harmonisation and
barrier alleviation for whole of
ASEAN power system. [1]
The ASEAN Power Grid Vision
It is well known that collectively,
the ASEAN region is generously
endowed with abundant and
reasonably diverse energ y
resources ranging from oil
reser ves, natural gas, and
coal to the large potential of
hydropower, and geothermal.
However these resources are
unevenly distributed between
the countries.
In the Greater Mekong Subregion (GMS) which covers areas
where the Mekong River flows Lao PDR, Myanmar, Cambodia
and Vietnam; there is a large
potential for hydropower energy
generation. It has been reported
