On 17 October, the AER received a revenue proposal from Transgrid for the SIPS battery service component of the WSB project. The revenue proposal sets out a schedule of quarterly payments that are proposed to be paid to Transgrid as the Network Operator for the project and, in turn, to the SIPS battery service provider (Akaysha Energy).

The EII Regulations do not permit the AER to publish a revenue proposal from a Network Operator.

We will make our determination in accordance with the EII Act, the EII Regulations and the AER’s Revenue determination guideline for NSW contestable network projects. Under clause 50 of the EII Regulations we have 42 business days to make a determination (that is, by 14 December 2022).
