Portugal and Blackstart From Tapada Do Outero Central: Japanese Infrastructure Strategic Protection

On April 28, 2025, Portugal faced the largest energy collapse in the twenty -first century, when 15 gigawatts collapsed on the Spanish network the entire Iberian Peninsula for widespread blackout. The country’s salvation depends on an infrastructure built in 1999: Tabada PVP station in Gondumar, which was held by the Japanese group Marubini. This report analyzes the accident, the technical mechanism of BlackstartThe decisive role of this main center in recovering the national electrical system, while highlighting the geopolitical and strategic effects of its Japanese administration.

Contemporary of obfuscation: the failure of the waterfall and the isolation of energy

The origin of the collapse on the Iberian Peninsula

At 11:35 April 28, Technical failure in solar gardens in Andalusia It caused 10GB of photovoltaic energy and 3.3 GW in Spain, immediately destabilizing the synchronous Iber network. In 1.5 seconds, forcibly fluctuating (from 50 Hz to less than 47.5 Hz) the automatic generator closed in Portugal, leaving 10.3 million people without electricity.

Isolation of Portugal and relying on Blackstart

While Spain regained the regime, with the support of France and Morocco, through interconnection, Portugal was isolated due to the lack of a 400 -volt effort from the very high font (VHV) with Madrid. This position requires activation Blackstart -The procedures that allow the restarting of the network without external energy -depending on the exclusive national infrastructure: Bode Castle Hedroelectric (138 MW) and Tapada Tapada thermal Do (990 MW).

Tapada Do Outeiro Center: Technical Architecture and Blackstart

The technical characteristics of the infrastructure

It is run by Turbogás (EML), and the center of the integrated cycle in Thill Tapada contains three Siemens 330 megawatts turbines, which are fed by natural gas or diesel, with a self -start capacity. Its simultaneous generators maintain rotten reserves (self -deficiency), which are necessary to fix the frequency during salaries. In addition, the Douru River site allows continuous cooling even in the scenarios of collapse.

Mechanism Blackstart: Complexity and implementation

S. Blackstart It includes three stages:

IndependentActivating turbines using generators diesel Internal, without relying on the network.
Create energy islandsFood priority from critical sub -stations (such as Maia, Porto) to rebuild the network.
Periodic synchronizationOther central and international bonding.

In Tapada do Outeiro, the operation started at 2:23 pm, after three failed attempts to photovoltaic photovoltaic. At 5:07 pm, the Central reached 20 % of the capacity, allowing the reactivation of the crane knot (Gondomar), gradually, the industrial north.

Marubini: The Japanese strategy in the Portuguese critical infrastructure

Acquisition and management by Marubini

A MarubiniCreating with 167 years of history, he took full control of Tapada Do Outeiro in 2024, after dissolving Joint project ROTECERENERGY With the French Engineer. The process was compatible with the Japanese Investment Strategy in Flexible European Energy Assets, with the aim of safety in the post -authority context.

Public service and profitability contracts

Beyond the free market, Marubini He maintains the public service contract with the Portuguese state by 2030, where he obtained 8.2 million euros per year for the availability Blackstart. This form is profitable even with the operation of the center less than 15 % of the annual capacity.

Technical challenges and blackout lessons

An exposed weakness in the electrical system

Excessive dependence on intermittent renewable energy sourcesThe penetration of 84 % of the wind and solar energy by 2024 reduced the stalemate from the system, which exacerbated instability during the collapse.
The scarcity of positions with Blackstart: Only 0.3 % of the national proven capacity has this function.

Strategic responses to the Portuguese government

Flexibility plan 2030Building two new gas centers with Blackstart (Sines and Tagus), budget with 1.2 billion euros.
