17th May 2013
Bihar is an agrarian state with 70% rural population;
Agriculture is backbone of Bihar's economy;
Agriculture generates nearly 42% of the State GDP;
Approx. 81% workforce employed in agriculture production (National avg. 60%);
Agriculture power consumption in Bihar
All India average
Haryana (highest in India )
Per capita consumption in Bihar (lowest in India) :
122 Units
All India average
770 Units
Abundance of fertile land, multi-cropping, high water table in most areas;
The state has high irrigation potential since water table is high;
Success dependent on availability of adequate electricity for irrigation, AgroIndustries;
Through proper electrical infrastructural support, state can emerge as big
supplier of agri-products and can supply its produce to big markets of nearby

Present status of Agri. supply
Existing Arrangement
 Power supply to Agri. Pumps done by 11 KV mixed load feeders through
11/ 0.4 KV Transformers.
 Such 11 KV mixed load feeders supply power to all categories of loads;
Pit-falls :
11 KV feeders, DTs & LT lines are common for all rural loads thus adversely
affecting power supply to pump-sets due to following:
 11 KV lines - more faults prone due to long length of line & higher load;
 Power drawn simultaneously by all categories of consumers leading poor
voltage profile for agriculture load;
 Peak demand shoots-up excessively forcing restriction due to limited
availability of power;
 Losses are on higher side owing to low HT/LT ratio;
Measures to improve Agri. power supply
Initiative taken by Govt. of Bihar to provide assured
and quality power for agriculture purposes:
A. Flagship scheme of “Dedicated Feeder for Agriculture”
under “Krishi Road Map (Rainbow Revolution)”;
B. Distribution Network strengthening & constraints
removal through BRGF Scheme;
C. Agriculture supply through Renewable energy sources;
A. Krishi Road Map
Govt. of Bihar has launched a flagship scheme of “Dedicated Feeder for
Agriculture” under “Krishi Road Map (Rainbow Revolution)”;
An ambitious scheme of the Government of Bihar under “Krishi Road Map”;
Rainbow Revolution envisages min. 7% of annual enhancement of agriculture
growth having target of almost doubling the food grain production in the next ten
To enhance the agricultural production;
To promote agro based industries;
To create electrical infrastructure for reliable and assured power supply during
specific hours for agricultural purposes;
To increase cropping intensity from 151% to 191% by FY 2016-17 and to 243% by
FY 2021-22 and corresponding irrigation intensity from 85% to 158% by FY
2016-17 and to 209% by FY 2021-22;
Patna District selected for pilot project;
To be implemented in all the 38 districts of Bihar;
Key features of scheme
 Installation of new 11 KV feeders in techno-economic manner
crisscrossing the agriculture terrain;
 Installation of HVDS and up-gradation of associated distribution
 Installation of distribution transformers of appropriate capacity near
load centre;
 Installation of system and agriculture Consumer’s energy meters for
proper accounting of energy;
 Ring-main system with proper isolation at every 5 km for better O&M of
 Renovation of associated Power Sub-station and service lines wherever
 Assets mapping, associated GPS survey and overall strengthening
and improvement of the distribution network;
Under the aegis of Rainbow Revolution, Energy Department, Govt. of
Bihar has prepared a road map for creating electrical infrastructure
for distribution of electricity to make reliable and assured Power
supply available for agriculture purposes.
Benefits of the scheme
 Optimal use of ground water resources through regulated
supply of power for irrigation purpose;
 Transformation of rural based agro economy;
 Reduction in failures of agriculture pump-sets due to
improved voltage;
 Holistic development of rural economy to improve standard
of living, quality of life leading to overall socio-economic
 Uninterrupted power supply to agri-consumers during
specified period;
 Flattening of load curve in judicious way thereby reducing
the cost of power purchase and adherence to Grid discipline;
 Improvement in quality and life of rural populace;
Survey approach
Survey outcome
B. Distribution network strengthening
Sustainable power distribution sector to ensure quality power
supply to end consumers.
Strengthening & renovation of distribution system through
removal of distribution constraints of entire distribution
licensee area of Bihar.
 Improved distribution system capacity to cater future load
 Improvement in quality & reliability of power supply;
 Reduction in system/ network failure rate;
 Assurance of uninterrupted power supply;
Action plan
 Strengthening of existing 33 kV feeders & construction of new 33
kV lines;
 Upgradation, Renovation and modernization of 33/11 kV Power
Sub-Station & addition of new 33/11 kV PSS;
 Strengthening of protective systems in 33/11 kV Power SubStations;
 Provision of capacitor Banks in 33/11 kV Power Sub stations;
 Rearrangement of existing 11 kV feeders & new 11 kV line;
 Upgradation, Renovation and modernization of Distribution
 Strengthening of L.T. lines (removal of Bans- Balla);
 System and Consumer metering;
 Use of phase separators in LT lines & Guard wires in HT lines;
Measures to remove Distribution Constraints
 Identification of the weakest areas in distribution network value
 Analysis of loading condition of Grid Sub-Station & Power SubStation;
 Analysis of loading conditions of the 33kV, 11 kV, LT lines and
various equipments in normal and peak situations;
 Identification of over loaded transformers, feeders, cables or
 Installation of distribution transformers of appropriate capacity
based on load profile;
 Installation of shunt capacitors to improve the power factor;
 Analysis of data for creation of MIS for existing loads, operating
conditions, forecast of expected loads etc.;
C. Renewable energy for Agri. consumption
To provide water to farmers for additional revenue generation through
more crop cycles per year;
 2 HP (1500 W) / 1800 Wp SPV Pumping System;
 Pilot project: 10 Blocks in 5 Districts (Saharsa, Araria, Supaul, Purnia
& Kishanganj);
 Short listing & Empanelment of Vendors is in final stage;
 Empanelled vendors will be notified to respective District Magistrate;
 In twelfth plan 2500 unit are proposed at the cost of 78.75 Crores ,
Unit Cost estimated at Rs. 3,15,000;
 Of this 39.38 Crores will state share and 23.6 Crore will be Central
share remaining will be the beneficiary share;
 In the year 2013-14, 1000 units are proposed;
Mini Rice Mill
Mini Rice Mill with 100% Producer Gas Engine 32 KW
with 60 KW Gassifier for all PACS a.
 Huge scope of establishing Mini Rice Mills with Single Fuel Mode
Gassifier Engines based on Renewable Energy;
 Subsidy for this scheme is available from MNRE (for Captive
Power Plant), Industries Department (For Rice Mill)
 The balance component will be provided through the beneficiary
account. Discussion regarding provision of balance component
through a loan by German Development Bank is proposed.
 In the twelfth plan 148 units are proposed at the cost of 22.22
Crores of is 4.14 Crore will be state share and 6.66 crore will be
