Ordinary households would be the last to be affected by any blackouts this winter.
That's according to Brian Ó Gallachóir, director of MaREI and professor of Energy Engineering at UCC.
This followed system alerts from Eirgrid last week.
It warned while there is enough electricity to meet demand, there's possibly not enough in reserve if something goes wrong.
Prof Ó Gallachóir told Pat Kenny the system we have means houses will be protected.
"The ordinary consumers are the most sheltered.
"In the situation where we would face a supply disruption of electricity, the householder would be the last to be affected by this.
"Not all EU countries have this in place, but we do have that - so there is clarity around that".
He says we also have "indigenous supplies to our electricity that helps as well to shelter the domestic customers".
However he adds that we still don't know enough about what will happen.
"It's something we need to take seriously this winter - the risk of disruption of supply is greater.
"But I'm not saying that it's going to happen.
"We don't know, there is uncertainty around this - so we need to really apply the precautionary principle here".
Meanwhile tech giant Amazon has been given the go-ahead for two new data centres in north Dublin.
The projects at will be at Clonshaugh Business and Technology Park, north of Santry.
The development, which got the green light from Dublin City Council, would be on an area of around 3.75 hectares.
This is despite concerns from environmental groups that it could place further pressure on limited energy supplies.
