Emerging Grid Reliability Challenges in the Western U.S.
As electricity demand grows and wildfire risks increase, the Western U.S. is reshaping how it plans, operates, and protects the electric grid.
Utilities and regulators across the Western U.S. are advancing interconnection reforms, transmission expansion, and wildfire mitigation measures as rapid load growth and climate-related risks place increasing…Read the full report
Key Takeaways
- Utilities and regulators across the Western U.S. are advancing interconnection and transmission planning reforms to address growing electricity demand from electrification and large energy users such as data centers.
- Large load growth is placing additional demands on grid planning processes, with ERCOT tracking approximately 410 GW of large load interconnection requests as of March 2026, up 178 GW since the end of 2025.
- Wildfire mitigation is becoming a core component of utility reliability planning, with increasing emphasis on risk-based planning, advanced monitoring and detection technologies, and expanded regulatory oversight.
