- In September 2024, Hitachi Energy collaborated with Tirreno Power to install Italy's first eco-efficient 420-kilovolt (kV) SF6-free circuit breaker. Manufactured at Hitachi Energy's facility in Lodi, this pioneering equipment is scheduled for installation in 2025. This initiative marks a significant step towards enhancing the sustainability of Italy's electricity network.
- In August 2024, Mitsubishi Electric Corporation and Siemens Energy Global GmbH & Co. KG signed an agreement to co-develop Direct Current (DC) Switching Stations and DC Circuit Breaker requirement specifications. This collaboration aims to realize Multi-terminal High Voltage DC (HVDC) systems, facilitating the efficient operation of large-scale renewable energy resources and contributing to global decarbonization efforts.
- In July 2024, Siemens Energy, GE Vernova, and Hitachi Energy partnered with German transmission system operators TenneT, Amprion, 50Hertz, and TransnetBW to develop multi-terminal hubs equipped with DC circuit breakers. These hubs are designed to efficiently connect newly developed extra-high voltage direct current (HVDC) transmission lines, enhancing the integration of renewable energy sources into the grid.
- In 2024, Siemens expanded its smart circuit breaker offerings by integrating Internet of Things (IoT) capabilities and AI-driven predictive analytics for real-time fault detection and grid management. These advanced circuit breakers are tailored for smart grid applications and residential smart homes, reflecting Siemens' commitment to innovation in electrical protection solutions.
- In 2024, Eaton introduced a new series of IoT-enabled circuit breakers designed for integration with energy management systems in commercial and industrial applications. These devices collect real-time data and offer insights for system optimization, aligning with the growing demand for smart, connected solutions to improve operational efficiency.
