Indian Economy on revival path?

Economy estimated to grow at 6 % in 2009-10 according to

RBI, weakest GDP growth projection in seven years due toweak monsoon & impact of global downturn.

Indian business has started showing signs of recovery drivenby strong domestic demand after the dismal performanceduring last year.

Fiscal & monetary stimulus measures initiated in 2008-09coupled with lower commodity prices has catalyzed domesticdemand.

Encouraging IIP data rekindles revival hope, Industrial output

jumped by 7.8% and power by 8% in June 09.

Constrained private investment in Infrastructure projects due toinadequate shelf of bankable projects and shortage of longterm finance for projects

11TH Plan Power Sector Update

Power deficit has increased over the year to 11.1% in FY09with peak deficit at 11.9%.

Regional situation is chronic with western region havingpeak deficit of 19% in FY09.

T&D losses continue to be on the higher side. (approx 27%)

Under Investment in T&D Sector .

The present investment in Generation and T &D Sector is1:0.5 as against the desired ratio of 1:1.

11TH Plan Power Sector Update

Against target Generation capacity addition of 78,700 MWgenerating capacity of 80,610 MW is under execution

15,036 MW already been commissioned (Aug09) -19%

65,574 MW Projects are under construction - 83.32%

Inter-regional transmission capacity addition to reach37,700 MW by March 2012, as of now 20,700 MW hasalready been reached.

Power Grid : Business Environment

The 11th five year plan envisaged an investment of Rs. 55000

Crores by Power Grid.

Interregional power transfer capacity to be increased to 37,700 MWby 2012 under Phase-III of National Grid Programme.

Majority of the schemes associated with UMPP and Regionalsystem strengthening finalized now.

Plans to Increase total Transmission lines by over 45% betweenFY08-12 (by adding 29,907 cKm).

Doubling transformation Capacity by adding 74,720 MVA between2008-09 and 2011-12.

Field test for 1200 KV UHVAC in collaborative effort with equipmentmanufacturers is under progress at Bina in Madhya Pradesh.

State Utilities: Business Scenario

The transmission systems in most of the states is being

upgraded/revamped after years of neglect and lack of investments

by the state utilities.

With rapid industrialization and growing power requirements, many

states decided to set up high capacity intra-state power

transmission systems.

The majority of the new projects are 400 KV voltage ratings with

twin, triple and Quad bundle configurations.

Different utilities follow different specifications and in many cases

the specifications have not been updated for last several years.

PPP (Public Private Partnership) model is being adopted by many

utilities to attract private investment in transmission sector


20/29

Private Sector : Initiatives

18,177 MW is expected to be added by IPPs/MPPs being developedby Private Sector during the 11th plan.

Non availability of capacity in the existing transmission systems hasnecessitated setting up of dedicated transmission lines by thesedevelopers.

Some developers have tied up with state/Central Utilities to set upthe transmission lines either on JV or on consultancy basis.

Private developers like ESSAR,JAYPEE & Adani are setting up inter-state transmission lines by directly inviting bids.

Many projects of similar nature are expected to be floated astransmission capacities are not expected to be available in nearfuture as well.

Stringing Capabilities

Stringing execution capacity increased by over 30% from 2007.

TSE machines added after 2005-06 are suitable for Quad conductor stringing400/765 KV.

Recently new TSE M/c additions are being done for Hexagonal conductor

stringing for 800 kV HVDC lines.

Challenges

28

Timely Placement of Orders for capacity planning & utilization.

Long gestation period between NIT and Award of Contract.

Delays in Right of way and Forest clearances.

Technology up gradation in construction.

Acute skilled Manpower Crunch both Managerial and supervisory.

Non - Standardization of Specification among Utilities in many casesnot updated for many years.

Commercial conditions such as terms of payment, Price Variation

clauses are often not rational and lead to unrealistic price levels.

Fast resolution of Contractual Issues and early closure of contract.
