NOS has no involvement in the design, architecture, or operational decisions
More than a year after a blackout darkened emergency communications across the Iberian Peninsula, Portugal's state-run network SIRESP has placed a formal price on the failure — €343,865 in contractual penalties, most of it directed at telecom operator NOS. The dispute arrives at a perennial question in critical infrastructure: when the systems meant to summon help go silent, where does responsibility truly reside? The answer, for now, remains unresolved, suspended in reconciliation talks whose outcome will determine whether accountability is financial fact or merely a formal gesture.
- Over a year after the April 2024 blackout crippled Iberian emergency communications, SIRESP has formally demanded €343,865 in penalties from its service providers — a delayed reckoning that signals the system is still processing its own failure.
- NOS, facing €340,502 of that bill, is pushing back hard, insisting it delivered every service the contract required and that SIRESP alone controls the network's design and operational decisions.
- The dispute exposes a structural tension at the heart of outsourced critical infrastructure: the line between supplying transmission pipes and bearing responsibility for how those pipes are woven into a life-saving network.
- No money has changed hands yet — reconciliation talks between SIRESP and its suppliers are ongoing, and the final financial impact will only materialize once those negotiations close.
- The stakes extend beyond invoices: the blackout degraded emergency response across an entire peninsula, making this a dispute about public safety accountability as much as contractual compliance.
More than a year after the April 28, 2024 blackout swept across the Iberian Peninsula, Portugal's emergency communications operator SIRESP has put a formal number on the failure. The state-run network is demanding €343,865 in contractual penalties from its service providers — €340,502 directed at telecom operator NOS for terrestrial transmission and satellite redundancy services, and a smaller €3,362 at Moreme for a separate contract segment. The Ministry of Internal Administration confirmed the figures, noting that the penalties have been formally communicated to the suppliers involved.
The process, however, is far from settled. Reconciliation procedures between SIRESP and the penalized companies are still underway, and the actual deduction of these amounts from future invoices will only occur once those talks conclude. The final bill could yet shift.
NOS is contesting the charge entirely. The company maintains it fulfilled every contractual obligation, providing transmission and satellite services exactly as specified. Its argument draws a firm boundary: NOS supplies the infrastructure; SIRESP designs the network, makes operational decisions, and governs its architecture. Any systemic failure in how those services were deployed, NOS contends, belongs to the network operator — not the supplier.
The dispute reaches beyond money. The April blackout degraded emergency response capabilities across an entire peninsula, and the question of who bears responsibility for that silence is one the reconciliation talks have not yet answered. More than a year on, the system is still trying to assign the cost of a moment when the infrastructure meant to connect people to help went dark.
More than a year after the blackout that rippled across the Iberian Peninsula on April 28, 2024, Portugal's emergency communications system has finally settled on a bill for the failure. SIRESP, the state-run operator of the national emergency network, is demanding €343,865 in contractual penalties from its service providers—a reckoning that arrived only recently, long after the incident itself faded from headlines.
The bulk of that sum, €340,502, has been directed at NOS, the telecommunications company responsible for terrestrial transmission circuits and satellite redundancy services. A smaller penalty of €3,362 goes to Moreme, which operates a different contract segment. The Ministry of Internal Administration confirmed these figures to media outlets, explaining that the penalties stem from service failures in the emergency communications system during the April blackout. The amounts have been formally communicated to the suppliers involved, though the process is far from complete.
What happens next remains in limbo. The ministry noted that reconciliation procedures are still underway between SIRESP and the penalized providers. The financial consequences—the actual deduction of these amounts from future invoices—will only take effect once those reconciliation talks conclude. In other words, the suppliers have not yet paid, and the outcome of their negotiations could reshape the final bill.
NOS, however, is pushing back. The company issued a statement asserting that it fulfilled its contractual obligations entirely. According to the operator, it provided terrestrial transmission and satellite redundancy services exactly as specified in its agreements with SIRESP. The company drew a sharp line between its role and SIRESP's: NOS supplies the pipes; SIRESP designs the network, makes operational decisions, and manages the overall architecture. "As a service provider, NOS has no involvement—and never has had any involvement—in the design, architecture, or operational decisions of the SIRESP network," the company said. Those responsibilities, it argued, belong exclusively to SIRESP itself.
The dispute cuts to a fundamental question about accountability in critical infrastructure. When an emergency communications system fails, who bears responsibility? The company that built and operates the network, or the companies that provide the underlying transmission services? NOS's position is that it delivered what was asked of it, and that any systemic failures in how SIRESP uses those services fall to the network operator, not the supplier.
The April blackout was significant enough to affect emergency response capabilities across the peninsula, making the stakes of this dispute more than financial. It was a moment when the infrastructure that connects people to help failed at a crucial juncture. Now, more than a year later, the system is trying to assign costs for that failure. Whether those costs will actually stick depends on conversations still happening behind closed doors.

La Conversación del Hearth Otra perspectiva de la historia
Why did it take more than a year to calculate these penalties?
The blackout happened in April 2024, but determining fault in a complex system takes time. SIRESP had to investigate what went wrong, trace it back to specific service failures, and calculate damages according to contract terms. That's not quick work.
So NOS is saying it did nothing wrong?
Exactly. NOS is saying it provided the transmission services it was contracted to provide, and that any failure in how those services were integrated into the larger network is SIRESP's problem, not theirs. They're drawing a line between being a supplier and being responsible for the whole system.
Is that a reasonable position?
It depends on what the contracts actually say. If NOS's job was just to keep the pipes open and SIRESP's job was to design and manage the network, then yes, it's reasonable. But if there's language in the contract about service reliability or system performance, NOS might have more exposure than they're admitting.
What happens if NOS refuses to pay?
That's where the reconciliation process comes in. If they can't agree, this likely goes to arbitration or court. The penalties don't actually come out of anyone's pocket until that's resolved.
And in the meantime, the emergency system is still running?
Yes. This is all about settling accounts for what happened. The system itself has presumably been fixed or improved since April. This is about who pays for the failure, not whether it's still broken.
