In this submission the Public Interest Advocacy Centre (PIAC) commented on the proposed tariff structure statements from the three NSW distribution networks. PIAC raised concerns about the proposed declining block tariffs, the absence of an opt-in demand-based tariff and the use of a three-year time horizon in calculating the long run marginal costs. Overall, the transition to cost-reflective pricing and demand-based tariffs is a significant change in electricity pricing and PIAC reiterates its concerns that this transition considers the long-term interests of consumers and that consumers benefit from the new tariff structure.
