thermal power development - Infraline

Central electricity authority Annual Report 2009-10
• BHEL was impressed upon for augmentation
of manufacturing capacity, advance
placement of order for long delivery of
critical items, availability of adequate
construction machineries, augmenting
erection of construction teams, high pressure
welders and skilled fitters etc.
• Sensitizing the industry to the need of
capacity building in manufacturing/supply
of main plant equipment and balance of
plant equipment.
• Reviewed and shared the qualifying
requirements for possible adoption by
project authorities to enable participation by
new vendors.
• Detailed schedules were drawn up for
equipment supplies and project milestones
commitments from project authorities and
equipment suppliers/executing agencies for
on-going 11 th Plan projects.
• Took up the issue regarding employment
visas for foreign personnel employed on
power projects to avoid delays in projects
where equipment was outsourced from
abroad etc.
6.5 Thermal Capacity Addition
Programme
6.5.1 Capacity Addition achieved during
2009-10
During the year 2009-10, thermal
capacity of 9106 MW was added against a
programme of 13002 MW, which is the highest
addition in any previous year. The details of the
projects programmed/ commissioned during
the year are shown in Annexure-6C. Some
of the main reasons identified for the delays
include delayed and non-sequential supply
of equipment, slow civil works along with
interfacing problems with equipment erection,
repatriation of erection and commissioning
personnel in projects sourcing equipment from
abroad etc.
6.5.2 Thermal Capacity Addition Target
during 2010-11
During the year 2010-11, a thermal
capacity addition of 17,793 MW is targeted.
Quarter-wise break up of the targeted capacity
addition is as under:
Year 2010-11
Capacity (MW)
Ist Quarter 3849.5
IInd Quarter 4644
IIIrd Quarter 4131
IVth Quarter 5168.5
Total 17793
The details of the projects are shown in
Annexure-6D.
6.6 Thermal Technology Development
6.6.1 Supercritical Technology
CEA has been actively associated in
developing road map for introduction of new
technologies for thermal power generation.
At present, the largest thermal unit size
in operation is 500 MW and a few units of 600
MW with sub-critical steam parameters are
under construction. CEA has been facilitating
adoption of higher size units with supercritical
technology. About 40 supercritical units of
660/800 MW are under construction and some of
them would be commissioned in 11 th Plan itself.
Initial supercritical units were designed with
parameters of 247 kg/cm 2 , 537/565 0 C. Higher
parameters of 247 kg/ cm 2 , 565/593 0 C are being
adopted for new supercritical units. In 12 th Plan,
supercritical units are likely to constitute a
majority of coal based capacity addition.
Efforts have been made to encourage
international manufacturers to set up
manufacturing facilities for supercritical units in
