Flexible AC Transmission Systems (FACTS)

Modern power grids face increasing stress from rising electricity demand, integration of renewable energy, and aging infrastructure. These challenges lead to voltage instability, power quality issues, and congestion in transmission lines, limiting the ability to move power efficiently and reliably. Traditional solutions like building new lines are costly and time-consuming, making it essential to find smarter ways to enhance grid flexibility and stability.

Hitachi Energy’s Flexible AC Transmission Systems (FACTS) portfolio provides advanced power electronics solutions that act as “smart controllers” for the grid. By dynamically managing voltage, reactive power, and power flow, FACTS devices eliminate bottlenecks, improve stability, and maximize the use of existing assets—reducing the need for expensive new infrastructure. They enable seamless integration of renewables, enhance grid reliability, and lower transmission losses, delivering a more efficient, resilient, and sustainable energy system.
