State <strong>Report</strong>s (Vol.-III)<br />

Study on `Impact <strong>of</strong> Restructuring <strong>of</strong> SEBs’<br />

two Sub LDCs at Dadri and Narwana at an estimated cost <strong>of</strong> Rs 34 crore in 2002<br />

under the unified scheme <strong>of</strong> northern region.<br />

Presently, 41 sub-stations <strong>of</strong> HVPNL are covered and reporting the real time flows<br />

(MW, MVAR) and digital status values to the SLDC through Remote Terminal Unit<br />

(RTU). About 220 more sub-stations are being planned for integration with the<br />

existing SLDC at an investment <strong>of</strong> Rs 200 crore approximately with the consultancy<br />

support <strong>of</strong> <strong>Power</strong> Grid Corporation <strong>of</strong> India Ltd.<br />

Reactive Energy<br />

HVPNL is continuing to pay for the reactive energy charges to the NREB pool<br />

account. The trend analysis for HVPNL available with NRLDC suggests that HVPNL<br />

loses around Rs 4 to 5 crore per year due to reactive energy drawls. This is in spite <strong>of</strong><br />

adequate capacitor banks installed by HVPNL as shown in the graph below:<br />
