thermal power development - Infraline

Central electricity authority Annual Report 2009-10
From the Chairperson
The Power Sector in India registered a growth of 6.6% in 2009-10 against the
previous year growth of 2.74% with gross power generation by various utilities
being 771 Billion kWh as against the previous year power generation of
724 Billion kWh. The growth would have been higher but for less power generation
by hydro power stations.
The definition of commissioning of generating units has been revised by CEA and
now a unit is declared commissioned only after it has attained full load on the
designated fuel. During the year, a total of 9,585 MW generation capacity was
added which comprised 9,546 MW Thermal (including 440 MW of Nuclear) and
39 MW Hydro, thus raising the Installed Capacity of the country to 1,59,398 MW.
CEA closely monitors the progress of various constructional activities of thermal
power projects under execution in the country. Project monitoring related activities
emerge from Section 73 (f) functions and duties of authority of Electricity Act, 2003 which inter-alia envisages
“To Promote and Assist in Timely Completion of Various Schemes and Project.” Visits are made by CEA
officers to the project sites for assessing the progress of various construction activities and rendering necessary
advice/assistance in resolving the problems being faced by the project authorities to meet the schedule of
commissioning. The Construction Monitoring groups of CEA are constrained by non-availability of IT based
monitoring system at the project level which is essential for effective monitoring.
During the year 2009-10, a total thermal capacity of 9,106 MW was added against the programme of
13,002 MW, which is the highest addition in any previous year. The private sector has responded enthusiastically
to the opening up of the power market and a substantial amount of generating capacity is coming up through
IPPs in coal, lignite, gas and hydro power projects. The private sector contributed 1,970 MW to thermal
generation capacity during period 2002-07. Since then thermal generation capacity of 5,920 MW has been
commissioned in 11 th Plan and another about 16,266 MW thermal generation capacity is under construction in
private sector. The private sector is likely to contribute substantial generating capacity in the 12 th Plan period
(2012-17).
Ultra Mega Power Projects (UMPPs) are being promoted by Ministry of Power with a view to provide power
to all at a reasonable rate and ensuring fast capacity addition as an initiative facilitating the development of
UMPPs of 4,000 MW capacity each. Out of nine (9) UMPPs proposed to be set up in different states initially,
four UMPPs one each in M.P., Gujarat, Andhra Pradesh and Jharkhand have been awarded and transferred to
the developers selected through tariff based international competitive bidding and are at different stages of
implementation. As per the present status of projects intimated by the developers, one unit of 660 MW of Sasan
UMPP and two units of 800 MW each of Mundra UMPP are expected to be commissioned in 11 th Plan.
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.
Initially supercritical units were designed with parameters of 247 kg/cm 2 , 537/565 0 C but now 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 India so as to create indigenous
manufacturing capability. As a result, four joint venture companies have been set up between international
manufacturers and Indian companies for manufacturing supercritical boilers/turbo-generator in the country.
To kick start the new joint ventures, bulk tendering of 11 Nos. 660 MW supercritical units of NTPC & DVC
has been undertaken by NTPC through International Competitive Bidding (ICB) with the mandatory condition
that the successful bidders would have to set up manufacturing facilities in India as per Phased Manufacturing
Program (PMP) being specified in the bid document. CEA has been actively associated in the whole process and
the progress of PMP would be monitored by a Committee under CEA.
CEA/Ministry of Power had instituted a Comprehensive Award Scheme for efficient and economic operation of
thermal, hydro and nuclear power stations, transmission system and power distribution companies as also for
