Rs. 1600 Crs. Mordernisation of Eastern & Western Regions RLDCs

underway. Estimated cost : Rs. 564 Crs. Schedule : ER by June ’05 & WR by March’06

Modernisation of RLDCs

WR ULDC: Challenges

Initial delays caused by non availability of concurrence from Constituents.

POWERGRID making efforts to reduce execution time from 4 Year to 3 Year. Scheduled Commissioning -March’ 2006 Expected Commissioning - March’ 2005

Dovetailing of existing SCADA/EMS of Maharashtra into Regional ULDC scheme.

Integration of communication network of Gujarat being setup by them.

Setting up of SLDC for GOA at this stage of Project.

Main Feature of Unified Load Despatch System

Unified Supervision & Control of Grid throughdedicated Communication System on real time Basis. Supervisory Control & Data Acquisition ( SCADA)

Real time acquisition of critical electrical parameters like Voltage, Frequency, MW & MVAR

Real Time Energy Management System Contigency Analysis Optimum Power Flow for reliability & security of the system Merit Order Operation including Hydro-Thermal Mix

Load Forcasting Quick Restoration of Grid in case of disturbance Real Time Environment For Training Operators to

cope with contingencies

Modernisation of RLDCs

Has Resulted Into: Considerable Improvement in System Parameters viz.,

Frequency & Voltage. Merit Order Operation, Leading to Overall Economy Introduction of ABT (Availability Based Tariff), resulting in

improved Grid stability Transparency in grid operation Quantum leap in intra and Inter Regional Power Exchange

and Trading Infused Grid Discipline

THERE HAS BEEN NO MAJOR GRID DISTURBANCE IN LAST 22 MONTHS

POWERGRID the Transmission Utility

POWERGRID started its commercial operation in 92-93

Over 40% of total power generated ( about 45,000 MW) is wheeled by POWERGRID

It operates & maintains 50,000 Ckms. of EHV Tr. System along with 82 Sub-stations at over 99% system availability.

Contd..

POWERGRID the Transmission Utility

Excellent performance is through:

Robust system design after detailed studies with thrust on integrated development

Deployment of Hot line maintenance technique

Use of Emergency Restoration System

Trained and dedicated manpower with decentralized administrative powers.

Attracting Private InvestmentAttracting Private Investment Established First Public-Private JV Company in

Transmission Sector with Tata for implementation of Tala Transmission system at an estimated cost of Rs 1374 Crore.

Two more projects i.e. Transmission System associated with Koldam, Parbati & Maithon, Estimated to Cost Rs 1300 Crore, have been floated under JV route.

Transmission lines under Western Region Strengthening scheme (Estimated Cost: Rs 4,800 Crore) is also being considered for implementation under JV route.

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