The Delegation

Indian Power Grid – its Evolution• Phenomenal expansion since Independence

Generation : 1349 MW 101,866 MW (in 1947) (in 2001)

Grid :

Local grid – at the time of Independence.

State Grids – emerged in 1960s.

Regional Grids – in 1970s.

Five Regional Grids – Northern, Western, Southern,

Eastern & North-eastern

National Grid – under progress.

Grid Operation by POWERGRID• Earlier performed by personnel from Central

Electricity Authority on the platform of REB• Transferred to POWERGRID in stages

-SRLDC 1994-ERLDC 1995-WRLDC 1996-NRLDC 1996

• Overall improvement in grid operation since takeover by POWERGRID

Overall Improvements by POWERGRIDOverall Improvements by POWERGRID

o Better hydro-thermal mix through objective & rational Scheduling.

o Better merit order operation enhancing the overall efficiency.

o Effective use of transmission lines and enhanced utilisation of their capabilities, retaining stability margins.

o Better commercial practices.

o Improvement in grid parameters (e.g. voltage, frequency profiles).

o Better utilization of Inter-regional links.

o Infused the grid discipline.

o Lower backing down of Power plants.

Strategic Plan

for

Diversification

into

Telecom Business

• Convergence - merging and overlapping of traditionally unrelated industries to provide essential services – provides opportunity to add value to the business

• Power Transmission utilities can provide alternative broadband network at incremental cost– Valuable Right-of-Way readily available– Optimal utilisation of infrastructure– Sturdy and stable infrastructure– Less prone to vandalism and rodent menace– Proven technology

WORLDWIDE DIVERSIFICATION IN TELECOM

World wide utilities like electric, gas, railways, water and roads have

successfully diversified into telecom business

Electric - 63% , Gas - 18%, Railways - 12%, Water - 7% and Roads - 2%

Majority of these utilities are Transmission Utilities

Out of about major 50 utilities, 30 are Transmission Utilities in UK,

Germany, Italy, Spain, Japan , USA etc.

New entrants have been successful in penetrating long distance market

BUSINESS RISK / REWARD ASSESSMENT

Phased Scheme of Implementation POWERGRID plans to enter Telecom business in a

phased mannerPhase-I (Selective Commercial Services)

– Utilise the spare/ excess capacity already available under modernisation of load despatch and communication facilities

– Enter Telecom business as IP-II & introduce value added services • Internet Data Centers and Managed Network Services to be

introduced in 1-2 year time

• International Connectivity

Phase-II (NLDO Participation) To enter into NLDO segment with a strategic partner

by forming a Joint Venture Company

Telecom Road Map

• POWERGRID Builds and operates Capacity Business and Value Added Services on a focused network ( ~14,000 Km)

– Delhi - Mumbai progressively by Mid, 2002

– Hyderabad – Bangalore – Chennai by October 2002

– Delhi – Hyderabad by October 2002

– Hyderabad – Calcutta by December 2002

– Delhi – Calcutta by December 2002

– Network to be completed by December 2003

Telecom Network – Map (Audio Visual)

Technology• State-of-the-art Technology adopted • Transmission Equipment

– Synchronous Digital Hierarchy (SDH) and Dense Wave Division Multiplexing (DWDM)

• Optical Ground Wire (OPGW)– Mostly Live line installation without disturbing the

power system– Capable of carrying SDH & DWDM

• Network Management System (NMS)– Network to have a dedicated NMS for monitoring &

maintenance of the telecom network from central location

– Four remote independent Regional NMS

• Future Proof
