Effective Voltage Regulation for Distribution Grids

Electricity demand is growing faster than ever — driven by electric vehicles, data centers, and heat pumps. At the same time, more power is being generated from renewable sources like solar and wind.

This shift is reshaping distribution networks. A traditionally centralized system with a few large producers is becoming decentralized, with many smaller generators feeding directly into local grids. The result is frequent voltage fluctuations, curtailment of renewable energy, and even supply disruptions for consumers.

Traditional grid reinforcements — new cables, substations, or feeders — are expensive, time-consuming, and often environmentally disruptive.

There is a smarter, faster way forward.

Hitachi Energy’s Voltage Regulating Transformer portfolio offers a seamless solution to stabilize grids, maximize renewable energy integration, and support new loads.

Designed for easy integration, these transformers fit directly into existing grid infrastructure, which is often as simple as replacing a conventional distribution transformer.

Covering ratings from 250 kVA to 20 MVA, the portfolio offers the flexibility to choose the right solution for every feeder, every network, every challenge.
