Duration: 1 year (start date: June 2024)

Partners: EDP & IONATE


EDP is testing IONATE’s cutting-edge transformer (HIT), which increases data visibility and real-time control of the flow of energy in electricity grids, essential features to support the transformation of the sector and accelerate the energy transition.

This project has already commenced with a design study this summer and will continue with testing with Labelec, before live deployment of HITs with E-REDES in Portugal and Spain, and also in the Brazilian market with EDP. Beyond the initial trial phase, IONATE’s HITs are planned to stay in the grid as permanent assets and help its transition over the next years.

This collaboration with the British startup IONATE was born following the participation of this emerging company in two key innovation programs: Free Electrons, the world's largest innovation program in the energy sector, co-led by EDP, and Energy Starter, EDP's collaborative innovation program, launched with the aim of attracting the most innovative and disruptive startups and scaleups capable of driving the energy transition on a global scale.


The IONATE’s Hybrid Intelligent Transformer (HIT) replaces the passive transformer with a real-time control node, regulates voltage and reactive power with millisecond-level precision by using magnetics in an innovative way. This stabilizes power flows and gives the grid operator a much-needed tool for active intervention. With its new capabilities, HIT increases the grid’s tolerance for renewables and the amount of power it can carry while minimizing wasted power on the way. Ultimately, they will gradually transform the network into a flexible, smart grid, optimizing power flows across the whole system.
