Immediately following a disaster, an initial damage assessment must be performed through the plant level emergency management group (EMG) to assess the impact of disaster on the electrical infrastructure. The assessment should give a rough estimate of the type and the extent of damages, involving probable cost and the required for financial assistance.
While the information has been collected it should be transmitted to the State and the Central Government. Once the State receives the preliminary damage assessment information, the State and the Central Government teams have to initiate a joint damage assessment. The joint damage assessment team comprising local, State and Central Government officials would conduct the assessment to determine the area of impact, the severity and magnitude of damage and the resulting unmet needs of the substations/transmission systems, etc. While the State and local resources are inadequate to effectively respond to an emergency or disaster, the Central assistance should be sought through the State.
