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

To have
Establishment of Modern RLDCs Has Resulted In:
Considerable Betterment of System Parameters viz., Frequency & Voltage in spite of Minimal Generation Addition
Merit Order Operation, Leading to Overall Economy
State-of-the-art technology in grid operation by introduction of ULD & C Schemes.
Introduction of ABT (Availability Based Tariff), linked to frequency variation
Transparency in grid operation
Quantum leap in intra and Inter 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 20000 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

(A) CAPACITY CHARGE
(B) ENERGY CHARGE
(C) ADJUSTMENT FOR DEVIATIONS (U I CHARGE)
Where
(A) = a function of the Ex-Bus MW availability of Power Plant for the day declared before the day starts x SEB’s % share
(B) = MWh for the day as per Ex-Bus drawal schedule for the SEB finalised before the day starts x Energy charge rate
(C) = Σ (Actual energy interchange in a 15 minute time block – scheduled energy interchange for the time block) x UI rate for the time block
TOTAL PAYMENT FOR THE DAY = (A) + (B) ± (C)
