During the 21st century adoption of electric motor for irrigation operation will be much more resulting a sharp rise in demand for electricity. The electricity requirement for planning, design and operation of irrigation and water resources systems is necessary. It is a parameter of prime importance in formulating the policy for distribution of electricity as well as decision making in day by day operation and management of electricity distribution network. The study was done for the year 2010-11. Average rainfall of the selected districts Arwal, Nawada, Gaya, Jehanabad, and Aurangabad varies from 950 to 1100 mm. Maximum temperature rise upto 45oC and minimum falls to 2oC. The study was conducted on maize, rice, wheat, sugarcane and potato crops. The cropping intensity of the Bihar state was found 146 %. Information about area cultivated under different crop, cropping system, crop yields, rainfall, climatic parameters, water table depth below ground surface were obtained from different Departments. These data were used to calculate the electricity requirements by using ENIRRMOD (Energy IRRigation MODel) model for irrigation operation. Total ground water pumpag required in study area was found 33.63 million ha-m. The total electricity requirement by electricity operated tubewells for irrigation operations in Kharif season from June to October was found 1469.00 million kWh and during Rabi season from November to May its requirement was 238.40 million kWh. The energy requirements for Aurangabad district was found 536.91 million kWh which was highest among the study area. The energy expenditure in the month of June was found maximum and least in the month of May. The average electricity requirements to apply one hectare meter of water (Irrigation Energy Intensity) in study area was 696.79 kWh/ha-m.
