In the morning of 19 July, Fingrid announced that domestic electricity production and import might not be sufficient to cover electricity consumption and an electricity shortage situation was possible. Electricity producers and consumers participated actively in balancing the situation and additional electricity was obtained from neighbouring countries.
The Olkiluoto nuclear power plant units were reconnected to the main grid on 19 July and 20 July. The substation fire did not jeopardise nuclear safety.
