According to the authorities, the Iranian nuclear power plant Bushehr has been shut down because of a "technical error".
The Iranian Atomic Energy Agency announced on its website that the plant was "temporarily shut down and taken off the grid."
At first there was no more detailed description of the problem.
"If the technical error has been rectified, the system will of course be connected to the national power grid again," said the authority's brief statement.
This should be the case "in a few days".
Citizens should use less electricity
A representative of the Iranian electricity company Tavanir told the AP news agency that the power plant would be shut down for three to four days.
Power outages could therefore occur.
It is the first time Iran has reported an emergency shutdown of the plant.
The electricity company asked citizens on Sunday to minimize their consumption during peak times.
The reasons she cited were a "predicted rise in temperature" and "restrictions on power generation due to ongoing repairs at the Buschehr plant".
Bushehr is in the south of Iran.
The nuclear power plant was built with Russian help and put into operation in September 2011.
Russia is also taking back nuclear waste.
In 2016, Russian and Iranian companies started building two additional reactors in Bushehr.
This is expected to take around ten years.
