Contingency plans are in place to monitor and quickly address any grid disturbance. Since May 13 has been declared a special non-working day, NGCP’s critical units, such as System Operations (SO) and Operations and Maintenance (O&M), remain fully staffed and operational. Line crews, engineers, pilots, maintenance and testing, and other technical personnel are also strategically positioned in NGCP substations to respond to line trippings, should these occur.
