As previously explained, many of Energex’s existing legacy tariffs were developed in the early 1990s. But now, with widespread uptake of rooftop solar and air-conditioning, the introduction of batteries and electric vehicles, large-scale uptake of energy-intensive appliances, and new technology to supplement or alter access to energy, many of Energex’s customers have very differing energy needs. This means that the old generic tariffs no longer cover network supply costs, or support a fair and equitable allocation of network costs.
So Energex have been challenged to develop this suite of new tariffs to maintain their commitment to safety, affordability, security, and sustainability for all customers. They explain that their proposed tariffs aim to reduce cross-subsidies between customer classes, minimise uneconomic investment in solar PV and emerging technologies, contribute to an increase in network utilisation, and delay or defer network investment in augmentation, power quality, and voltage management.
