POWER SECTOR PLANNINGOverall planning for the power sector is done

by Planning Commission

Planning Commission is an advisory body atapex level, headed by Hon’ble Prime Minister ofIndia and functions towards achieving theIndia and functions towards achieving theobjectives of the Government

The Commission is primarily involved in :The Commission is primarily involved in :• Formulating Five Year Plans and Annual Plans in consultation with

Central Ministries and State Govts., for effective and balancedtili ti f t ’utilisation of country’s resources

• Review implementation of Plan and advise corrective measures• Assessment of material, capital and human resource of the country

AUGUST 2008 SKA 3

and formulation of proposals for augmenting such resources

Five year plans lay out targets for each areaPOWER SECTOR PLANNING

Five year plans lay out targets for each areain the sector viz. Generation, Transmission,Distribution etc.

Currently XI plan is under progress (FY2007-08 to FY 2011-12)

Key indicators for planning :• Projected Demand• Indigenous Production of Primary Energy Sources• Electricity Generation and Per Capita Consumption
