The Central Electricity Authority (CEA) has notified guidelines for medium- and long-term power demand forecast. The guidelines aim at providing a basic framework of medium- and long-term power demand forecast for a discoms/state/union territory. As per the guidelines, the forecast should be prepared for medium term (more than one year and up to five years), and for the long-term (for the next 10 years at least). The detailed power demand forecasting exercise should be undertaken every five years. However, the forecast should be reviewed on yearly basis and updated, if required.
