San Francisco International Airport (SFO) has outlined its energy conservation plans to voluntarily support Flex Alerts.
Flex alerts are issued when extremely hot weather drives up electricity use, making the available power supply scarce. The California Grid Flex Alerts are usually issued between 4pm and 9pm, when consumers are using air conditioners, lights, and appliances.
When a Flex Alert is issued, SFO may implement any or all of the following measures:
- The AirTrain people mover may reduce the frequency of service from every 4 minutes to every eight minutes. Travellers are advised to allow extra time during any Flex Alert periods.
- Electric vehicle (EV) chargers in all SFO Parking Garages may be temporarily deactivated
- Airport cooling may be adjusted to reduce electricity usage. Travellers should prepare for slightly warmer terminals during a Flex Alert, SFO said
- Airport lighting may be reduced throughout terminals.
SFO expects to receive 24 hours’ advance notice of any Flex Alert.
