ULD & C PROJECT: OBJECTIVES  Greater and deeper visibility of the power system under control  Dedicated real time communication and co-ordination between various control centers in the region  Effective management of grid parameters viz. frequency, voltage etc. and better grid security through various SCADA/EMS features resulting in better Operation scheduling Operation monitoring and control Power system analysis  Real time dispatcher training To have

Establishment of Modern RLDCs Has Resulted In:  Considerable Betterment of System Parameters viz., Frequency & Voltage in spite of Minimal Generation AdditionBetterment of System Parameters Minimal Generation Addition  Merit Order Operation, Leading to Overall Economy Merit Order  State-of-the-art technology in grid operation by introduction of ULD & C Schemes.  Introduction of ABT (Availability Based Tariff), linked to frequency variationABT (Availability Based Tariff),  Transparency in grid operation  Quantum leap in intra and Inter Regional Power Exchange and TradingInter Regional Power Exchange and Trading  Infused Grid Discipline

POWERGRID’s Diversification Into Telecommunication  To utilize the spare capacity of ULDC Schemes and maximize return on its transmission infrastructure, POWERGRID decided to diversify into Telecom Through an incremental investment All India fibre optic network of kms spread over 60 cities including all metros and major cities  Telecom Networks on Transmission Infrastructure Sturdy and secure rodent menace free Vandalism proof 100% availability

POWERGRID’s Diversification Into Telecommunication  DWDM /SDH equipment deployed  Scalable to terrabit capacity  Obtained IP-II licence in Jan 2001 and ISP category A licence in May 2003  kms, connecting 46 Cities Commissioned.
