Indonesia Inaugurates Three Coal Plants
Indonesian state-owned utility Perusahaan Listrik Negara (PLN)
formally launched operations at three new coal-fired power plants
on Dec. 28. The 625-MW Banten 1 plant in Suralaya, Banten, a
$478 million project built by the China National Technical Import
and Export Corp. and Indonesia's state-owned Rekayasa Industri,
is expected to consume 2.9 million metric tons of coal annually,
with supplies coming from Kalimantan and Sumatra on a 20-year
contract. The project was completed in 54.5 months.
The $808.4 million Banten 3 project in Lontar, Banten, has a capacity
of 3 x 315 MW and was built by a consortium that included
Chinese power equipment giant Dongfang Electric Corp. and Dalle
Energy. The two Banten plants are expected to be supported by the
completion of a transmission network connecting Labuan, Saketi,
and Rangkas Bitung, three cities in Banten province.
In central Java, the government also started up two new 662MW
units at the existing 1,320-MW Tanjung Jati B coal-fired
power plant (Figure 5). The $2.06 billion expansion project was
built by Japanese firm Sumitomo Corp., Wasa Mitra Engineering,
and Bangladeshi power firm Summit Power Development Ltd. for
Sumitomo subsidiary Central Java Power. Toshiba Corp. and Toshiba
Plant Systems & Services supplied the turbine and generators,
Mitsubishi Heavy Industries supplied the coal-fired boiler, Black
and Veatch supplied auxiliary facilities for the boiler, and Mitsui
Engineering and Shipbuilding Co. executed civil works. PLN has
leased that plant from Central Java Power for 20 years.
The plants' official inauguration follows the Nov. 3 opening of
China Shenhua Energy Co.'s PT.GH EMM INDONESIA Unit 2, a 150-MW
unit built adjacent to an existing twin unit at the facility. The new
plants are part of the first phase of power shortage-stricken Indonesia's
ambitious plan to fast-track 10,000 MW of new capacity.
Poised for skyrocketing economic growth, Indonesia is seeing
a power demand surge of about 9% annually. The country's power
capacity stands at about 30 GW, but in order to avoid rolling blackouts
that plagued the country two years ago and secure a 35%
reserve margin, Indonesia has planned to add 10,000 MW of new
capacity by 2014, most located on the main island of Java. Most
new plants in the short term are coal-fired, though several expensive
diesel units have been deployed to meet immediate power
needs. But analysts have tempered enthusiasm for the country's
ambitious plans because they say several issues could delay plans

December at Central Java Power's existing 1,320-MW Tanjung Jati B
coal-fired power plant in Jepara, a coastal village a three-hour drive from
Semarang on the Indonesian island of Java. Courtesy: Sumitomo Corp.
to add capacity, including land acquisition problems.
Meanwhile, as part of its effort to boost capacity, in late November,
the country's National Nuclear Energy Agency approved
plans for construction of the country's first nuclear power plant
in the Tanjung Ular Muntok Cape region, West Bangk, by 2016.
The controversial proposal for a nuclear power plant in the quakeprone
country had been delayed after the Fukushima accident in
Japan in March 2011.

ANDRITZ to Rebuild Oldest Egyptian Nile Dam. Austrian firm
ANDRITZ HYDRO on Dec. 22 won a $138.4 million contract from
the Egyptian Ministries of Energy and Water Resources for the
supply and installation of four bulb turbines, generators, and
the electrical and hydro-mechanical equipment to rebuild the Assiut
barrage-the oldest dam in the Egyptian section of the Nile
River. The rebuild is expected to improve conditions for irrigation
and shipping as well as produce up to 32 MW when completed by
2017. ANDRITZ said the Assiut project uses Kaplan runners with
only three blades, perfectly suiting the low design head and its
variation margin from 3 to 6.5 meters (9.8 to 21.3 feet).
CapX2020 345-kV Line Completed in Minnesota. Minneapolis-based
Xcel Energy in late December said a 345-kV, 28-milelong
segment of the CapX2020 transmission project between the
new Quarry Substation near St. Cloud and the existing Monticello
Substation in Minnesota was placed into service. The project is
double-circuit capable, which allows for future capacity expansion
on existing structures. CapX2020, a $2 billion joint initiative
of 11 investor-owned, cooperative, and municipal utilities
in Minnesota seeks to expand the grid over a distance of more
than 700 miles. In addition to the newly completed line, projects
in the first group include two other 345-kV lines: between Alexandria
and St. Cloud (construction to begin in early 2012) and
between Brookings County and Hampton (to begin April 2012).
Construction of a 230-kV line from Bemidji to Grand Rapids is
under way and expected to be complete in late 2012.
Wärtsilä to Build Its Biggest Power Plant, in Dominican Republic.
The Dominican Republic's largest power generation company,
Empresa Generadora de Electricidad Haina, granted a $194 million
turnkey contract to Wärtsilä on Dec. 27 for a complete dual-fuel
power plant that uses Wärtsilä's proprietary Flexicycle technology. In
the Flexicycle concept, the unique dynamic features of combustion
engines are maintained as the combined cycle can be shut on and
off individually for each generating set. The Quisqueya II power plant
will feature 12 Wärtsilä 50DF generating sets in combined cycle mode
running primarily on natural gas, but with the capability to switch to
heavy fuel oil, as needed, when fully operational during the second
half of 2013. The project is to be built as an identical plant, on the
same site as the Quisqueya I plant, which was ordered by Barrick Gold
in September 2011. Though the plants will have separate owners,
they will be operated from one control room. The 430-MW complex
will be " the biggest power plant in the world, delivered by Wärtsilä, "
the Finnish company said.
GE Refurbishes Spanish Cogen Plant. GE completed a major
repowering upgrade of its LM2500-PE gas turbine at Cogen España's
Tortosa Energía cogeneration plant in Tarragona, Spain. The
project that spanned five weeks-one-third of the time expected-
entailed converting the existing natural gas-fueled GE LM2500-PE
gas turbine to the more efficient, cleaner, and more powerful GE
LM2500+ DLE model. GE helped increase power output from 26 MW
to 29 MW at 37% efficiency in simple cycle mode/61% efficiency
in cogeneration mode. The plant's control system was updated,
