Section 3 of 5Understanding Grid Resilience
Grid resilience refers to the ability of electrical systems to anticipate, absorb, adapt to, and rapidly recover from disruptions. In an era of increasing climate change impacts, cyberattacks, and infrastructure aging, resilience has become a critical priority for modern grid operators.
Resilient grids employ multiple layers of defense, from physical hardening and cybersecurity to operational flexibility and community engagement. The goal is not just to prevent outages, but to minimize their impact and restore service as quickly as possible when they occur.
Resilience Dimensions
- Physical Resilience: Hardened infrastructure and redundant systems
- Cyber Resilience: Protection against digital threats and attacks
- Operational Resilience: Flexible operations and rapid response capabilities
- Community Resilience: Public communication and emergency preparedness

Building Resilient Systems
Grid resilience requires a multi-layered approach combining physical hardening, digital security, operational flexibility, and community preparedness. The key is anticipating threats and implementing cost-effective mitigation strategies.
