Distribution Projects

The Power sector in Bihar is currently undergoing sea change. The Power sector inBihar is growing at a faster rate to achieve national level of per capita consumption.The pace of economic development along with increasing power demand would requireadditional generating capacity as well as adequate distribution network infrastructureto cater the current demand and future load growth. In an effort to reduce lossesin power distribution sector, improve customer service and reliability of powersupply, the Distribution Companies of Bihar has undertaken a preliminary study toidentify distribution sector constraints from 33 kV line upto distribution transformerlevel, in course of further study it has been identified that the present distributionsystem of Bihar suffers from serious constraints in distribution infrastructuredue to which against as peak load requirement of 3000 MW the existing system iscapable of meeting load to the extent of 2300 MW - 2400 MW only. The distributioninfrastructure required for meeting the existing constraints and peak load requirementof FY 2013-14 has been covered under Phase-I of the scheme. The major action plansfor strengthening of Power Distribution system and removal of distribution constraintsdistribution system under BRGF Phase-I are as follows:

• New 33 kV lines and strengthening of existing 33 kV feeders;
• Additional PSS/Augmentation of existing Power Sub Stations capacities;
• Strengthening of protective systems in Power sub- stations;
• Provision of capacitor Banks in selected Power Sub stations;
• New 11 kV lines & strengthening of existing 11 kV feeders;
• Sectionalisation of 33 kV & 11 kV lines and provision of fault passage indicators(F.P.I.);
• Additional D.T./ Augmentation of existing Distribution Transformer capacities;
• Protection of Distribution Transformers and provision of individual isolators (A.B.switch) on existing DTs;
• Strengthening of L.T. lines (removal of Bans- Balla);
• Use of phase separators in L.T. Lines & Guard wires in H.T. lines;

In the second phase of BRGF scheme, the outlook of the Distribution Companies isto remove distribution constraints arising on account of the followings:

• Peak demand of 5620 MW (2016-17) as projected by CEA;
• Upcoming agriculture load as envisaged under “Krishi Road Map”
• Sub-transmission network requirement for renewable energy sources such as SolarEnergy etc.
