tomers that expressed a variety of desires.
Some asked for a turbine with more generation
power, some wanted efficiency,
and others wanted a model that could be
directly swapped out for the earlier turbine
module, the 9E.03. GE noted that
development of the 9EMax, which is part
of its " Fleet360* " platform of total plant
solutions, was completed by the " concurrent
engineering " (Figure 5) of a team of
300 employees around the world, including
engineers in the U.S., Poland, India,
and France, ultimately reducing time to
complete the new turbine development
project from four years to three years.
The validation test took place at an
installed unit at an unnamed utility customer's
site in Asia. " We completed the
'first fire' milestone with the unit successfully
reaching full speed at no load, and it
proved to deliver significantly more power
and efficiency compared to current 9E gas
turbine operations, " said Eric Gray, general
manager of Gas Plant Solutions for GE's
Power Services.
First Fire for a New F-Class Model.
GE on May 8 also celebrated first fire of a
60-Hz 6F.01 gas turbine at the Huaneng
Guilin Distributed Energy Project in the
city of Guilin, Guangxi province, China.
The project owned by China Huaneng
Group features an innovative " combined
cooling, heating, and power " configuration
that will be fueled by natural gas
upon completion. The plant uses three
6F.01 gas turbine units, which can achieve
a fuel efficiency of 81.15% and a total installed
capacity of 210 MW, GE said.
GE added that the turbines can deliver a
rapid startup, synchronizing to grid within
as little as eight minutes, achieving to full
load in less than 30 minutes. Gas distribu16
tion
energy projects are also capable of
generating peak power on demand, allowing
for shifting loads for gas and power
supply, it said.
Ansaldo Marks Milestone for GT26.
On May 5, Ansaldo Energia, a company
45% owned by the Italian state-owned
Cassa Depositi e Prestiti Group and 40%
by Shanghai Electric, announced it had
successfully completed the first phase
of a comprehensive validation program
of its GT36 gas turbine at the Birr Test
Power Plant in Switzerland. Power from
the full-scale simple cycle power plant
completed in 2016 is dispatched to the
Swiss power grid.
Ansaldo said the tests, which included
stress testing of the two stages of the
sequential combustion system, part- and
full-load mapping, transient operation,
and performance testing, fully confirm the
" high performance, low emissions over the
entire load range, and resulting very wide
operation window of this engine. " The test
results reported for the GT36-S6 (60-Hz
rating) confirmed power output above 340
MW at 41% efficiency, Ansaldo said. " In
combined cycle this corresponds to performance
exceeding 500 MW at 61.3% net
efficiency in ISO conditions and 720 MW
at 61.5% efficiency for the GT36-S5 (the
50-Hz scaled version), " it said (Figure 6).
POWER Digest
India Joins IEA as an Association Country.
India joined the International Energy
Agency (IEA) as an association country
on March 30, marking a significant move
for the country into global energy affairs.
The IEA said in a statement that the
country is emerging as a major driving
www.powermag.com
force in global energy trends, " with all
modern fuels and technologies playing a
part. " The Indian government said in a
separate statement that it would " richly
gain from the IEA's data gathering processes,
survey methodologies, and range
of energy data, which could enable India
in the near future to set up its own robust
integrated database agency. " Association
countries aren't IEA members. The
organization's membership is comprised
by 29 countries, all of which are part of
the 35-nation Organisation for Economic
Co-operation and Development. However,
the IEA works with a number of major
energy-consuming nations. Other IEA association
countries are China, Indonesia,
Thailand, Singapore, and Morocco. With
India as its newest association country,
the IEA said its operations now account
for about 70% of the world's total energy.
Siemens to New Build Cogeneration
Plant in Berlin. Siemens received an order
to build a new natural gas-fired combined
cycle power plant with district heat
extraction in the Marzahn district of Berlin
from Vattenfall Europe Wärme AG, the
company said on May 3. The 260-MW plant
is scheduled to begin operations in 2020.
Siemens' scope of supply includes the major
components-the gas turbine, steam
turbine, and two electrical generators-all
to be fabricated at Siemens manufacturing
plants in Berlin, Görlitz, and Erfurt,
Germany. It will also supply the heat recovery
steam generator. The unit is to be
erected in a multi-shaft configuration and
will achieve a fuel efficiency rating of approximately
90%. Siemens will also sign a
long-term service agreement covering the
gas turbine generator set.
Indonesian Court Revokes Permit
for Coal Plant in West Java. Objections
from local villagers on April 19 prompted
an Indonesian regional court in Bandung,
West Java, to revoke an environmental
permit for a 1-GW expansion of the 660MW
Cirebon coal-fired power plant (Cirebon
2) backed by Japanese firm Marubeni
and the Japan Bank for International Cooperation
(JBIC). The administrative court
case was filed in December 2016 by
six plaintiffs, including environmental
groups, which argued that the West Java
government inappropriately issued the
permit because it lacked an amendment to
a spatial plan and did not engage with the
community in the environmental impact
assessment process. The JBIC reportedly
led a coalition of banks that signed a loan
agreement to provide $1.74 billion for the
Cirebon expansion. While the decision may
still be appealed, the Cirebon 2 plant was
