How do electricity tariffs affect community-scale storage?
Different electricity tariffs impact the operation of the community-scale storage, and thereby impact the potential benefits for customers, battery operators and networks. Reducing tariffs for the local exchange of energy to and from the storage can improve the local consumption of solar energy, thereby reducing import and export peak loads.
What if batteries were to incur costs for exporting?
However, the AEMC identified that if batteries were to incur costs for exporting, they would have to receive something in return. Specifically, distributors would need to consider the different levels and types of services available that they can provide to battery owners. C.1.3. Problems with existing flat tariffs structures
Should batteries respond to a two-way tariff?
Batteries and other flexible loads are well suited to respond to truly cost reflective two-way tariffs that offer both charges and rewards. Tariff response by these customers provide an opportunity to reduce network costs.
What are grid-scale battery tariffs?
There are two types of grid-scale battery tariffs that we need to consider: transmission and distribution. In essence, this means understanding the network costs for batteries in the form of Transmission Use of System (TUOS) and Distribution Use of System (DUOS) charges. B.2.1. Transmission connected grid-scale batteries
Can batteries be exported?
Export tariffs for batteries The AEMC also highlighted that when developing tariffs for batteries, use of system costs must be considered. Under the Rules at the time, generators – including batteries when exporting –do not pay for using the network and consequently do not receive guaranteed access.
Should the Australian Energy Regulator approve export charges?
We welcome the indication in the Guidelines that the Australian Energy Regulator (AER) would only approve export charges where distribution networks can demonstrate that supporting exports is increasing network costs.
