12. POWERGRID’s Strategic Plan for Diversification into Telecom Business

13. 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 CONVERGENCE

17. 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

19. Phased Scheme of Implementation POWERGRID plans to enter Telecom business in a phased manner  Phase-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

20. 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)

21. 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

23. POWERGRID Telecom SERVICES Virtual Private Networks (VPN) Internet Data Centre (IDC) –Web Hosting –Co-location services –Dedicated Server Products –Application Service Provision NLD Services End-to-End Bandwidth SERVICES International Connectivity
