When the NI Electricity Industry was privatised in the early 1990s, there was concern that effect of the sale of the generators could be that the power station sites could be lost to the electricity industry at some future time. It was decided that the freehold of power station sites should vest within NIE in a quasi-trustee role. For this purpose, the NIE Land Bank Business. At present there are a number of vacant sites within the Land Bank and the Utility Regulator is consulting on their use.
