Niall Collins of Fianna Fáil accused the energy regulator of blocking proposed wind farms from connecting to the national grid.
Mr Collins said the sites were assessed as being suitable for wind farms. Some have already obtained planning permission but have not progressed to construction stage as licences were not granted by the energy regulator.
He said: “It’s a disgrace that this situation has been allowed to arise and smacks of double-speak The energy regulator has put the public in a terrible position by not allowing more renewal energy sites onto the national grid through the issuing of licences. We are overly dependent on the use of oil and gas-generated electricity for our energy needs.”
He was aware of wind farm sites in Co Limerick which are now lying idle.
