A storm damaged one of the main power lines to import electric energy. A blackout occurs
A battery starts a small diesel generator installed in a hydroelectric generating station.
The power from the diesel generator is used to bring the generating station into operation.
Key transmission lines between the station and other areas are energized.
The power from the station is used to start one of the nuclear/fossil-fuel-fired base load plants.
The power from the base load plant is used to restart all of the other power plants in the system.
Small gas turbines are used to provide the base power to energize the key transmission lines
The power from the base load plant is used to restart all of the other power plants in the system. Users are then connected to the grid starting for hospitals and governative institutions.
