This is the sector in which we have worked most, from the nuclear benchmark to remotely operated photovoltaic plants. And it heads the NIS2 list for a reason: without electricity, nothing else works.
The environment
Power generation combines extremes. On one side is nuclear: strict regulation, a mature safety culture and every change subject to a formal process; working there teaches a discipline we then apply everywhere. On the other are renewables: dozens of distributed plants operated remotely from a control centre, built by different EPCs to different criteria and connected by design to the manufacturers that maintain them remotely.
In between lies the conventional thermal and hydro fleet: long-lived DCS, turbines with proprietary control systems and heavy dependence on the manufacturer. The risk pattern repeats: extensive external connectivity inherited from construction and maintenance, and little visibility into what enters and leaves each plant.
How we work here
In generation, almost everything starts with access: inventorying and controlling who connects remotely—turbine manufacturer, EPC, market operator or remote-control provider—is the first useful outcome of the assessment. Next comes segmentation between plant and corporate networks and between plants in the same fleet, so an incident at one does not become an incident at all of them.
On that foundation, we provide centralised monitoring of the entire fleet: for an operator with nine plants, an OT SOC that sees them together costs a fraction of nine isolated solutions and detects patterns that none would see alone.
Applicable regulations
NIS2 places electricity in Annex I as a highly critical sector, with the strictest supervisory regime. IEC 62443 remains the technical reference, while facilities providing services to public authorities may also fall within the scope of Spain's ENS.
