One of the Administrators of the REN, the Portuguese electric supplier is currently giving a press conference. Confirmed they are in scenario of restart from black start.

- Cause of event not known yet.

- They noticed power oscillations from the Spanish grid that tripped safety mechanisms in the Portuguese grid. At the time, due to the cheaper prices, the Portuguese grid was in a state of importing electricity from Spain.

- They are bringing up multiple power systems and the Portuguese grid is able to supply 100% of needs if required. It was not configured in such a state at the moment of event.

- They had to restart the black start more than once, since while starting, noticed instabilities in some sectors that forced them to restart the process.

- Time for full recovery unknown at this time, but it will take at least 24 hours.
