The establishment of an island wide electricty market in November will not quite match the hype. There will not be standardised pricing across the island (although the two regulators will announce prices on the same day) nor will there be any short-term savings. As to when benefits will be gained the picture is unclear:
The CER and other sources agree that the single market will not result in a cut in the cost of power in the short term at least. A CER spokesman acknowledged that it would take some time before this happened and said that neither regulatory body could pinpoint when precisely the benefits would be felt. “It is more likely to happen over the medium term,”
A survey also suggests that NI businesses already enjoy cheaper electricity than their RoI competitors.
