The Department of Energy selected Ameren Missouri, Ameren Illinois and Pitch Aeronautics to deploy grid-enhancing technology across Ameren's transmission network under the DOE's Speed to Power (SPARK) initiative. The project pairs Pitch Aeronautics' weather-based dynamic line ratings across more than 8,000 miles of lines with new high-performance conductors on two high-voltage segments that will more than double year-round capacity. The broader SPARK program provides $1.9 billion in federal funding across 31 projects in 26 states; no project-specific award amount for Ameren was disclosed.
