NTPC has commissioned its
first supercritical power
generating unit, a company
release noted. The Central power
utility announced the commissioning
of one unit of 660-mw at its Sipat
power plant in Chhattisgarh. With
this, NTPC's total installed capacity including
those through joint
ventures-now stands at 34,854 mw.
The coal-fired Sipat project in
Bilaspur district has three supercritical
units of 660-mw (out of which one is
commissioned) and two of 500-mw,
both of which are operational. The total
operational capacity of Sipat, now at
1,660 mw, is slated to go up to 2,980 mw.
The project will power the western
region including Chhattisgarh, Gujarat,
Madhya Pradesh, Maharashtra, Goa
and the Union territories of Daman &
Diu, and Dadra & Nagar Haveli.
The Sipat power project was
commissioned with main plant
equipment sourced from Russian and
Korean suppliers. While OJSC Power
Machines of Russia supplied the
turbines, the boiler package was
sourced from Korea-based Doosan
Heavy Industries. A senior NTPC
official said that the remaining two
units of the 3x660-mw Sipat (Stage I)
project will be commissioned by the
end of this fiscal year.

It was widely believed that NTPC's
Sipat-Stage I, with orders for main
plant equipment placed way back in
2004, would be India's first
supercritical power project to turn
operational. However, the project was
fraught with unexpected delays
resulting from poor performance of the
equipment suppliers. It may be
mentioned that Adani Group's Mundra
power project in Gujarat is India's first
supercritical power project to turn
operational. The first unit of the
2x660-mw Mundra (Stage II) project
was synchronized in December 2010
while the second reached the same
milestone in early June this year.
Sepco-III of China has been contracted
to supply the main plant package. (See
Box Second for Adani)
The NTPC official also mentioned
that the power utility expects to
commission the Barh (Stage I)
supercritical power project in Bihar, in
the medium term, without specifying
any time frame. This 3x660-mw coalfired
plant is also coming up with
Russian equipment. OJSC Power
Machines is the turbine supplier while
boilers are being supplied by JSC
Technopromexport. The equipment
contract for Barh-I, valued at
3,258
crore, was signed in March 2005. Like
the Sipat-I project, the Barh-I project
also allegedly faced inordinate delays at
the hands of the Russian suppliers.
Second for Adani |
Adani Power has the distinction of
commissioning India's first
supercritical power unit. In December
2010, it synchronized to grid the first unit of
its 3x660-mw Mundra (Stage II) power
project in Gujarat. It did so in a record time
of 36 months. The second unit of the same
project was commissioned in June this
year. With this, Adani Power has fully
commissioned the first two phases of the
Mundra project aggregating 2,640 mw, with
six units of 330-mw in the first phase and
two supercritical units of 660-mw in the
second. The supercritical units were
supplied by SEPCO-III of China. The same
supplier has been contracted to build the
third phase comprising three units of 660-
mw each, scheduled to commission by
March 2012.
Adani Power has targeted to have nearly
6,000 mw of operational power capacity of
nearly 6,000 mw by March 2012. Out of
this, 4,620 mw will come from the Mundra
project and 1,320 mw from the Tiroda
supercritical plant in Maharashtra.

NTPC is also in the midst of
commissioning Barh-Stage II that is
based on supercritical parameters as
well. The 2x660-mw project will have
its boiler and turbine-generator
packages supplied by Bharat Heavy
Electricals Ltd (see table.)
India expects that over 60 per cent of
the new thermal power capacity
targeted for the XII Plan period would
come from fuel-efficient supercritical
units, while 100 per cent of such
capacity in the XIII Plan would be based
on this technology.

DPIL's new EHV cable plant |
Diamond Power Infrastructure Ltd has
announced the commissioning of a
new plant to manufacture EHV cables up
to 500kV. The plant was supplied by
Mallifer of France, a release by DPIL said.
DPIL joins the league of only seven
manufacturers worldwide that are capable
of manufacturing 500kV EHV cables, the
release noted. An official of DPIL told
Electrical Monitor that the plant has been
set up at Savli in Vadodara, Gujarat.
