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
T d Vill El ifi d• Towns and Villages Electrified• Sector-wise Consumption of Commercial Energy• Relative share of Different form of Commercial Energy
