Total Voltage Control
End-to-end voltage compliance for a low carbon grid

Voltage is a statutory limit, not guidance. As more generation and demand connect at the edge of the grid, keeping voltages within limits is getting harder.

Total Voltage Control brings together automatic voltage control, control scheme engineering, tapchanger support and LV network control into one ecosystem. Together with Fundamentals, part of EA Technology since 2026, we offer a seamless, integrated solution from primary substations to low voltage feeders, helping you stay compliant, connect low carbon technologies faster and defer costly reinforcement.
