District heating schemes are large-scale systems that are supplied by one or several centralised or decentralised heat sources and serve multiple buildings and multiple customers. Group, or communal, heating schemes are smaller-scale systems that supply single buildings or complexes. End users in group or communal heating schemes are supplied with heat rather than fuel and the heat supplier in these schemes purchases the fuel at commercial rates, primarily natural gas.
My Department is currently liaising with the Commission for Regulation of Utilities (CRU) to ensure the development of an appropriate regulatory framework for district heating. During this process, the CRU will assess the specific regulatory needs of group heating schemes to ensure their inclusion in a regulatory framework, as a priority.
