Improvements by POWERGRIDImprovements by POWERGRID Considerable Betterment of System Parameters viz.,

Frequency & Voltage in spite of Minimal Addition in Resources

Establishment of True Merit Order in Operation Leading to Economy At Country Level

Introduction of modern State-of-the-art technology in grid operation by introduction of ULD & C Schemes.

Introduction of tailor made commercial mechanism viz., ABT – Most suited to Indian peculiarities

Better communication facilities

Transparency in grid operation and Paperless working at RLDCs

Quantum leap in intra and Inter Regional Power Trading

Infused Grid Discipline

To utilize spare capacity of ULDC schemes and maximize return on its transmission infrastructure, POWERGRID decided to diversify into Telecom

Through an incremental investment

Telecom networks on Transmission InfrastructureSturdy & secure

rodent menace free

vandalism proof

Only utility in the country providing overhead fibre optic cable for telecom networks

DWDM/SDH equipment deployedScalable to Terabit Capacity

AVAILABILITY BASED TARIFF

(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)
