Building a power plant on a site previously used for an aquaculture farm comes with
more than a few challenges. For the Tanjung Bin Energy Power Plant, that meant
some redesign and rework was required. Even so, the GE-led construction consortium
made adjustments and delivered the state-of-the-art ultrasupercritical project
on time and on budget.

M
alaysia has undergone a miraculous
transformation over the past
50 years. According to The World
Bank, more than 50% of households in the
Southeast Asian country lived below the
national poverty line in the 1960s, but that
percentage has fallen to less than 1% today.
Malaysia has diversified its economy and is
now a leading exporter of electrical appliances,
electronic parts and components, palm
oil, and natural gas.
As the nation's people have prospered and
various industries have grown, so has Malaysia's
electricity demand. The country's
energy commission reported that electricity
consumption grew 8.39% annually from
1990 through 2013. Its 30 million people
consumed a little more than 123 TWh of
electricity in 2013.
Natural gas has long been the leading
power generation fuel source in Malaysia,
used for more than half of the country's
electricity mix. However, coal-fired genera28
tion,
which was nonexistent before 1989, has
grown steadily since 2000, displacing virtually
all of the oil-fired generation and picking
up most of the demand growth. Coal generation
accounted for 48% of Malaysia's mix in
2015, even though almost 98% of the coal
fuel supply is imported.
Modern Technology
One impressive coal-fired plant that has been
added recently in the state of Johor is the
Tanjung Bin Energy Power Plant (T4). The
1,000-MW unit-owned and operated by
Malakoff Corp. Bhd.-features ultrasupercritical
technology, which provides the most
efficient coal combustion technology currently
on the market.
T4 is located on 65 hectares of land adjacent
to the existing Tanjung Bin Power Plant,
which includes three 700-MW coal-fired units.
The plants share common infrastructure, such
as coal-handling facilities, power evacuation,
seawater intake, and other access services.

Malakoff, a member of the MMC Group,
was given the notice to proceed with T4's
construction in March 2012, following a
competitive bidding process overseen by
the Energy Commission of Malaysia. Alstom
(now GE Steam Power Systems) and
its consortium partners Mudajaya and Shin
Eversendai (Table 1) signed an engineering,
procurement, and construction contract
worth more than €1 billion to build the plant
on a turnkey basis.
The heart of the unit is a pulverized coal
two-pass, tangential-fired ultrasupercritical
boiler, utilizing GE's latest technology.
The advanced boiler design produces steam
pressure up to 280 bar (4,061 psi) and steam
temperature up to 600C (1,112F) while accommodating
up to 15 different types of coal.
" This technology has achieved efficiencies
up to 47 percent-above the global average
rate of existing power plants of around
30 percent-lowering fuel consumption and
emissions, " GE's Steam Power Systems
