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 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

12000 kms, connecting 46 Cities Commissioned . Rest to be commissioned progressively by September 2004

(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)
