Transmission Generation Heat Map — SPENOpenDataPortal

The "Transmission Generation Heat Map" data table provides an indication of the potential opportunities (or constraints) to connect to SP Energy Networks' transmission network by detailing all connected and contracted projects. This allows potential customers to have an interactive representation of the network and view the type of projects connected to specific substations within the SP Transmission area.

The table gives the following information:

Location of project
Connection site of project
MW connected
MW increase/decrease
Cumulative total capacity
Project status and date effective from

Disclaimer

Whilst all reasonable care has been taken in the preparation of this data, SP Energy Networks does not accept any responsibility or liability for the accuracy or completeness of this data, and is not liable for any loss that may be attributed to the use of this data. For the avoidance of doubt, this data should not be used for safety critical purposes without the use of appropriate safety checks and services e.g. LineSearchBeforeUDig etc. Please raise any potential issues with the data which you have received via the feedback form available at the Feedback tab above (must be logged in to see this).

This heatmap will be updated on a monthly basis using the published data from the ESO's TEC register, the latest ECR and the contracted demand data to ensure we have an accurate representation of projects the ESO has considered as connected and/or contracted. It is important to note, our refresh of this data won't always be aligned to the latest available version of the ESO TEC register. Therefore, there may be small discrepancies between the two datasets. For the most up-to-date version of this data, please visit the ESO TEC register.

Data Triage

As part of our commitment to enhancing the transparency, and accessibility of the data we share, we publish the results of our Data Triage process.

Our Data Triage documentation includes our Risk Assessments; detailing any controls we have implemented to prevent exposure of sensitive information. Click here to access the Data Triage documentation for the Transmission Generation Heat Map dataset.
