The "Transmission Generation Heat Map" dataset provides an indication of the potential opportunities (or constraints) to connect to SPEN's 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 SPEN Transmission area.For additional information on column definitions, please click on the Dataset schema link below.
Disclaimer: This heat map will be updated on a monthly basis using the published data from the ESO's TEC register 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.
