Around 4500 homes and businesses in Dublin city centre are without power after an electricity outage.
The problem, which started at around 11:30am, is affecting premises from Wood Quay to Merrion Square and some parts of the north city centre.
It's also impacting on traffic lights around Christchurch and Stephens Green.
ESB crews are working to fix the problem.
The outage is being blamed on construction firms hitting underground cables.
