EXECUTIVE SUMMARY
The assessment of the anticipated power supply position in the Country during the year 2011-12 has been made taking into consideration the power availability from various stations in operation, fuel availability, and anticipated water availability at hydro electric stations. A capacity addition of 17191 MW during the year 2011-12 comprising 14111 MW of thermal, 2080 MW of hydro and 1000 MW of nuclear power stations has been considered. The gross energy generation in the country has been assessed as 855 BU from the power plants in operation and those expected to be commissioned during the year in consultation with generating companies/ SEBs and take into consideration the proposed maintenance schedule of the units during the year. The monthly power requirements for all States/ UTs in terms of peak demand and energy requirement have been assessed considering the past trend and finalized in consultation with the concerned authorities taking into consideration the specific requirement, if any. The power supply position of each state has been worked out and the assessment of surplus/ shortages has been made which has been discussed at the fora of Regional Power Committees.
INTRODUCTION
The Load Generation Balance Report brings out the month wise likely position of the power requirement and availability and identifies the States with surplus power which could be procured/ contracted by the States facing deficit. The Load Generation Balance Report, brought out by the CEA in the beginning of the year also presents a review of the actual power supply position during the previous year in the country and an assessment of the power requirement during the year in the various States as also power availability from generating stations owned by them, their share in the common/Central sector projects, long term agreements.
Region wise Power Supply Position
All the Regions in the Country namely Northern, Western, Southern, Eastern and North-Eastern Regions continued to experience energy as well as peak power shortage of varying magnitude on an overall basis, although there were short-term surpluses depending on the season or time of day. The surplus power was sold to deficit states or consumers either through bilateral contracts, Power Exchanges or traders. The energy shortage varied from 4.3% in the Eastern Region to 13.3% in the Western Region.
Region wise/ State wise
A comparison of the constituent-wise actual power supply position both in terms of peak and energy as against the forecast in respect of various regions for the year 2010-11 is given in Annex –VII(A) & VII(B) respectively. Variation in energy availability and peak met of the states were caused by changes in allocation from central sector projects and bilateral energy contracts of the states, which were not envisaged during the preparation of LGBR.
Overview
The exercise for anticipated power supply position in the country for the next year 2011-12 involves (a) assessment of power requirements in each State (month wise) in terms of unrestricted energy requirement and peak demand and (b) realistic estimate of electricity availability both in terms of energy and capacity from various sources. While the peak demand and energy requirement in the States are worked out on the basis of the trend analysis considering the actual data for the preceding years as also the specific load requirements, if any, as per established methodology; the energy availability is worked out on the basis of generation targets set by the Operations Performance Monitoring Division, CEA after detailed consultations with the generating companies/SEBs and approved by Ministry of Power. The Regional Power Committees prepare the estimates of month-wise power requirement and availability for each of its constituents and finalize the same in consultation with them. The region wise power supply position is coordinated in Grid Management Division, CEA to arrive at the all India power supply position.
