Hitachi Energy Introduces Compact Line Voltage Regulator to Enhance Distribution Grid Controllability

Hitachi Energy has introduced its latest innovation for modern distribution grids – the Compact Line Voltage Regulator (C-LVR) – at CIRED 2025, the leading international conference on electricity distribution.

The C-LVR is an integrated solution that combines voltage regulation and power transformation into a single, compact product. Designed to fit seamlessly within the same footprint as a standard distribution transformer, it enables active voltage control at the feeder level without requiring additional space or infrastructure modifications.

As distribution systems adapt to support decarbonization and decentralization, they face new operating challenges, including reverse power flows and increasingly volatile loads. The C-LVR addresses these challenges by delivering stable voltage performance where it is needed most – at the edge of the grid – in a compact, familiar, and easy-to-deploy format.

By merging the functionality of a traditional distribution transformer with advanced LVR regulation, the solution automatically compensates for voltage fluctuations, ensuring reliable voltage levels without the need for costly grid expansions. It is suitable for both new network designs and retrofit projects, requiring no extra components, space, or redesigns. In addition, the system is SCADA-compatible and ready for integration into standard compact secondary substations (CSS) and digital grid environments.

With the launch of the C-LVR, Hitachi Energy completes its comprehensive portfolio of voltage regulation solutions. The range now spans from distribution transformers with tap changer capabilities at individual grid nodes, to the C-LVR at the feeder level, and traditional power line voltage regulators at the head of the line—providing end-to-end voltage control for evolving distribution networks.
