New figures show that almost 1,300 gas and electricity domestic customers a month were disconnected in the first six months of the year.
However the number of customers cut off is down almost 30% on the same period last year.
The Commission for Energy Regulation has said it will start naming the companies and how many disconnections they have carried out in the next set of figures.
The figures show that in the first six months of this year, 7,720 gas and electricity domestic customers were disconnected.
That represents a 29% drop on the same period last year when 10,592 were cut off.
There was a significant drop in gas disconnections. However, on average, 1,285 domestic customers are being cut off every month.
ESB said that up until June of this year, 150,000 of its customers are in arrears, while it has put in place 130,000 payment plans.
Bord Gáis says 110,000 of its customers are more than €100 in arrears, while it put in place 45,000 new payment plans up until June.
Airtricity did not provide figures, as it said it was commercially sensitive. A company spokesman said it had noticed an increase in the number of customers in difficulty making payment arrangements.
