2027, the company said. The plant will provide
a substantial boost to TNB's existing
installed hydropower capacity of 2.5 GW.
Over the last 72 years, TNB has operated
only three hydropower dam facilities: the
1.2-GW Sungai Perak Scheme; the 622MW
Cameron Highlands Scheme; and
the 665-MW Kenyir Scheme. Currently,
hydropower accounts for 18% of TNB's
Peninsular Malaysia's generating capacity.
Coal power represents 45.6% and
gas power 35.9% of its total capacity.
The company, which has assets across
the world, says it embraces a low-carbon
economy, and will support renewables
and energy efficiency as part of its efforts
to reduce greenhouse gas emissions.
X-Energy Creates Dedicated TRISO
Fuel Subsidiary. X-energy, a U.S.-based
developer of the Xe-100 Generation IV advanced
reactor, in mid-August moved to
operate its fuel division as a wholly-owned
subsidiary called TRISO-X. The division
will commercially develop the company's
proprietary tristructural isotropic (TRISO)
fuel for the burgeoning advanced nuclear
energy sector. Pete Pappano, X-energy's
vice president of fuel production, will lead
the new company as its president. X-energy
has reported it is ready to begin commercial
production of TRISO after years of
refining its TRISO fabrication processes.
The newly launched division TRISO-X is
poised to break ground on a commercial
facility to meet an Xe-100 deployment
schedule that anticipates at least four Xe100
modules coming online in Washington
state by 2027. Plans are also underway for
a second fuel fabrication facility in Canada
to serve the Canadian market. The move
caters to Ontario Power Generation's
(OPG's) decision to build a small modular
reactor (SMR) at its Darlington Nuclear
Station in Clarington, Ontario, as early as
2028. OPG last year kicked off advanced
engineering and design work for that
project by choosing three SMR developers:
GE Hitachi, Terrestrial Energy, and
X-energy. However, while the utility says
it hasn't yet " absolutely decided it's going
to be one of those three, " it anticipates
picking an SMR vendor for Darlington at
the end of this year.
Siemens Energy, CTCI Win Contract to
Build 1.1-GW HL-Class Gas Plant in Taiwan.
A consortium of Siemens Energy
and Taiwanese engineering, procurement,
and construction company CTCI Corp.
on Sept. 7 announced they will build the
1.1-GW Sun Ba Power Phase II Combined
Cycle Power Plant in southwestern Taiwan
for independent power producer Sun Ba
Power Corp. The project, which will be
October 2021 | POWER
fired with regasified liquefied natural gas,
will use Siemens HL-class technology.
Sun Ba II is designed as a multi-shaft
combined cycle power plant, in which
two gas turbines and one steam turbine
each drive their own electrical generators.
Siemens' scope of supply includes
the plant's power island, consisting of
two SGT6-9000HL gas turbines, one
SST-5000 steam turbine, three SGen62000P
generators, two heat recovery
steam generators, and the SPPA-T3000
control system. Siemens Energy will also
provide long-term service for the plant's
core components. Slated to come online
in mid-2024, the plant is expected to
become " an important building block in
Taiwan's energy transition, " which aims
to shift from coal and nuclear power to
environmentally friendly gas-fired power
plants and renewable energies.
Court Invalidates Permit for Germany's
Youngest Coal Plant. Datteln 4,
a 1.1-GW coal plant in Germany's North
Rhine-Westphalia region that was commissioned
in May 2020, was built and
began operating despite an invalid development
plan, a German higher administrative
court ruled on Aug. 26. But while
the ruling pitches a victory to the case's
plaintiffs, which include an environmental
group and the city of Waltrop, it does
not prohibit operation of the plant, which
is a modern power plant that boasts
an efficiency of more than 45%. However,
the court noted legal proceedings
against the plant's operating unit are
currently underway at another higher
administrative court. Uniper has said
it still holds the view that the permit is
legal, and unless legally compelled, it
has no intention of closing the plant. In
an earnings call on Aug. 11, Uniper CEO
Klaus-Dieter Maubach told investors his
company plans to take the plant offline
by the end of 2038 in line with Germany's
coal phase-out law. " Recently, in its
new climate protection law, the German
government has materially increased
the greenhouse gas reduction target for
2030, " he noted. " For the energy industry,
this means the old reduction path
from 257 million tonnes in 2020 down
to 175 million tonnes in 2030 has now
been decreased further, even down to
108 million tonnes in 2030. If a new German
government wants to talk about
the coal phase-out again in this context,
then we are prepared to talk. Of course,
such talks need to cover the question of
compensation as well, " he said. ■
