An amber alert on Ireland’s electricity generation system was lifted last night, according to a statement on the website of SEMO, the Single Electricity Market Operator.
SEMO is a joint venture between Eirgrid and SONI, the Northern Ireland grid operator.
There is a single market for electricity on the island of Ireland.
This was the second amber alert issued this week. There was another alert on Monday.
Amber alerts are issued when there is a threat to the supply of electricity.
This week’s alerts were caused by low levels of wind power generation due to calm weather conditions and the continuing maintenance work being carried out in two gas fired generation plants.
The plants, in Huntstown and Whitegate, are due to come back into use in November.
