Summary of Key Findings

Excluding weather, the bulk-power system (BPS) remains within

Adequate Level of Reliability (ALR) objectives

Weather continues to stress BPS reliability
No load loss due to cyber or physical security events
Average transmission outage severity declined
Significant decrease in transmission forced outages resulting in

loss of load

Stable frequency response trend
Increased risk in protection system misoperations
Continued decline in Energy Emergency Alert Level 3

No Load Loss Due To Physical or Cyber Security Events

BES Security Metric 1: Reportable Cyber Security Incidents
3 Reportable Cyber Security Incidents in 2014
None resulted in loss of load
BES Security Metric 2: Reportable Physical Security Events
47 reports of physical security threat events
9 caused physical damage or destruction
None resulted in loss of load
