Electrical Power Generation
Emergency electrical power is defined as an independent reserve
source of electric energy which, upon failure
or outage of the normal source, automatically provides
reliable electric power within a specified time.
A reliable and adequate source of electric
power is necessary for the operation of active industrial operations. Power must also be available at
to provide water for fire protection,
energy for automatic fire alarms, light for
security purposes, heat for preservation of critical
industrial equipment, and
for other operations.
Power, supplied by either the local utility company
or generated on-site. The source of distribution may be subject to
brownout, interruption or extended outage. Safety, and health requirements may require
an uninterruptible power supply (UPS) or
standby/emergency supply for specific critical loads.
Justifiable applications for emergency electrical power are:
- Hospitals (life support, operating room, emergency lighting and communication, refrigeration, boiler plant, etc.).
- A class B plant (considered a standby long term
power source) is used where multiple commercial
power feeders are not available or extended and
frequent power outages may occur.
- Airfields (control tower, communications, traffic control, engine start, security, etc.).
- Data processing plant systems.
- Critical machinery
- Communication and security.
