Today we publish a consultation paper on the review of DUoS (Distribution Use of System) domestic tariff charging methodology. This is one of our 2017/2018 Forward Work Programme projects.
This paper sets out our proposals for reviewing the domestic DUoS tariff charging methodology. If no change were to be made to the current structure it is possible that in the future suppliers may move away from charging a flat unit rate based retail tariff (with no standing charge element) and move to a retail tariff structure which has both a standing charge and unit rate. As such, customers could see the reintroduction of a standing charge in NI retail tariffs. Therefore, the decisions taken could impact on the structure of the electricity bills of NI domestic customers.
