<p style="text-align:justify"><span style="color:#696969"><span style="font-size:11px"><span style="font-family:arial">The&nbsp; Power Grid Corporation on Tuesday connected the southern power grid to the National Electricity Grid. The move will facilitate easier transmit of power from surplus states in other regions to several power-deficient southern states. &ldquo;Synchronous integration of the Southern grid with rest of the national grid shall not only augment the inter-regional power transfer capacity of Southern region but also relieve the congestion being experienced in a few transmission corridors,&rdquo; a statement released by the Power Ministry said. &ldquo;This would be a boost for further economic growth of the country. It is likely to take a few months before power flow over this line is stabilised.&rdquo; The country has five power grids: northern, southern, eastern, western and north-eastern and the southern was the last grid to be connected to the national system.</span></span></span></p> <p style="text-align:justify"><span style="color:#696969"><span style="font-size:11px"><span style="font-family:arial">FAQ on what this means for the southern states in particular and India as as a whole:</span></span></span></p> <p style="text-align:justify"><span style="color:#696969"><span style="font-size:11px"><span style="font-family:arial"><strong>How does this help? </strong></span></span></span></p> <p style="text-align:justify"><span style="color:#696969"><span style="font-size:11px"><span style="font-family:arial">Earlier, several power-deficient states in the south faced a problem in buying power from surplus states elsewhere as they were on a different transmission setup.

Also, being in the same transmission corridor would help prevent regular outages and trip-ups that took place earlier.</span></span></span></p> <p style="text-align:justify"><span style="color:#696969"><span style="font-size:11px"><span style="font-family:arial"><strong>Will prices in the south come down? </strong></span></span></span></p> <p style="text-align:justify"><span style="color:#696969"><span style="font-size:11px"><span style="font-family:arial">There used to be a substantial difference in merchant power rates in the southern states where prices sometimes reached as high as INR 15-20 per unit even as they stood at about INR 5 per unit in other states.
