System Wide Resource Register

The System Wide Resource Register (SWRR) has been developed to provide better information to electricity network stakeholders on connected resources and network services. 

The register implements an industry agreed format which has been developed through the Energy Networks Association Open Networks project and has been adopted by all Distribution Network Operators (DNOs). It provides information on generation and storage resources (≥1MW) that are connected, or accepted to connect, to SP Energy Network's distribution network and will be updated on a monthly basis.

The register also includes information about Flexibility Services that are being provided by connected resources, including flexible demand. The register will be expanded in July 2020 with further information which will include details about network reinforcements.

For this release of the register, some data fields have been redacted as DNOs are restricted by the Utility Act and other Network Codes from publishing information that would identify specific resources. Modifications to network codes are being progressed to overcome these restrictions. Subject to these modifications being agreed, all of the data fields will then be published.
