Federal Reliability Requirements 
 
Ameren’s Approach to the New Federal Reliability Requirements
In 2007 the Federal Energy Regulatory Commission (FERC) began mandating legally enforceable reliability requirements necessary to protect the transmission grid from disturbances. In response to these requirements, Ameren has adopted a proactive approach to right-of-way management. 
 
This involves:
  • Establishing greater clearances between trees and transmission lines.
  • Cutting incompatible trees down where the same trees had been trimmed in the past.
  • Asking landowners to move newly planted trees inappropriate for the location.
