OATI has expanded adoption of its webLineR™ software to help transmission owners comply with FERC Order 881, enabling automated ambient adjusted ratings (AARs) that unlock transmission capacity across multiple US regions, including utilities like Entergy and NextEra Energy. The platform automates complex hourly weather-based transmission capacity calculations, facilitating regulatory compliance and improving grid reliability.
This Wire brief sits within Fusion42's coverage of Climate Tech.
◆ ◆ The Wire takeaway
Transmission operators must upgrade to automated weather-based capacity tools or lose market access under FERC rules. If you provide grid software, accelerating integration with regional ISO/RTO platforms opens new sales doors.
