Business Case
Qualifying opportunities in power transformer diagnostics
SURFEO sized the market and interviewed more than 30 players for an engineering unit specialising in the diagnosis of electrical installations.
Shedding light on a market driven by the modernisation of power grids
In the European Union, annual spending on grids was expected to exceed $70bn in 2025, twice the level of a decade earlier [1].
An in-house engineering unit of a major French state-owned group, specialising in the measurement, diagnosis and prognosis of power generation facilities, wanted to clarify the opportunities related to power transformers.
SURFEO carried out a quantitative analysis, a qualitative survey and TAM/SAM sizing in order to identify market opportunities and trends.

Grids are becoming a critical point in the energy transition
Annual grid spending in the EU
Orders of magnitude published by the IEA [1].
Grids under pressure
The European Commission counts more than 11 million kilometres of grids in the internal market [2].
An exposed supply chain
According to the IEA, China accounts for 60% of European transformer imports [1].
Efficiency remains regulated
The European regulation sets minimum efficiency levels for transformers from 1 kVA upwards [3].
