Reacción a "Final blackout report by European operators confirms event was caused by multiple factors, recommends improving oversight and coordination"

Is the report based on sound data and methods?

‘Yes, the report has compiled all possible data, and where data could not be obtained (because it does not exist, or had been withheld or not shared), it has been simulated using a realistic model. The report has also analysed technologies similar to those currently in use to identify their response and behaviour. This means the results and conclusions are underpinned by a strong foundation of data and detailed analysis.’

What new insights does it provide?

‘It doesn’t really offer any major new insights compared to the October reports, which already presented some initial analyses. It reinforces the message that everything happened because it was a combination of problems that pushed the electricity grid to its limit.’

What data would you highlight?

"The key conclusions are that renewable energy sources were not to blame, although they can provide more support if required by the operator; that a system with greater inertia would have faced the same problem; and that there were issues with voltage and reactive power regulation. Regulations must be updated and there must be greater coordination between the active players in the electricity grid (as well as aligning the response of the protection systems); the electricity grid is a reliable and safe system according to the parameters and models used (planning and operation); and that the procedures implemented were those established".

What practical recommendations can we make based on this report?

‘One of the critical points is the coordination of protection systems, the control of low-power renewable energy sources (below 1 MW), and the need to dynamically update voltage regulation.

Furthermore, it reinforces the fact that it is possible to operate with high levels of renewables, but that regulation and the provision of ancillary services and grid support must be extended to all generation, whatever the type.’
