COVID - 19 IMPACT

Power Infrastructure Had to be Maintained as an Essential Service Industry; Medium and High Voltage Testing Industry Had a Mixed Effect During the COVID-19 Pandemic

The COVID-19 pandemic was disrupting the medium and high voltage testing market and meanwhile was affecting global supply chains and delaying several non-essential testing services. Critical power infrastructure continued to be tested especially for the systems supporting healthcare and essential services. Lockdown and overall economic uncertainty first dampened new investments into new power projects, which decreased demand for the related testing services. Despite that, the pandemic underlines the demand for good electrical infrastructure supply, which might eventually strengthen maintenance and testing activities in the long term. Market demand has rebounded to pre-pandemic levels, but growth is much slower than pre-pandemic trends in most regions.
