The Power Infrastructure layer makes it easier than ever to find substations, assess their capacity, and source sites in the right locations.

It’s turned on by default for all Power customers, so you can get started right away.

Not a Power customer, but interested in seeing the data? Get in touch with your account manager.

Now, let’s take a look at some frequently asked questions.

How do I find the Power Infrastructure layer?

The Power Infrastructure layer lives alongside all the other data layers. Click the drop-down menu on the top right of the screen and click onto the layer.

Don’t see the Power Infrastructure layer there? Contact your account manager and they can activate it for you.

How can I tell if a substation has capacity?

Each substation is colour coded to show its RAG (red, amber, green) status, as supplied by the applicable DNO.

  • Red = low capacity

  • Amber = medium capacity

  • Green = high capacity

As said, this data comes straight from the DNO. If the DNO hasn’t supplied the information, we mark them as white with a pink border.

In particular, UK Power Networks and Electricity North West don’t provide a RAG status for each individual substation. If you want to find out capacity information for their substations you will need to contact them directly.

How can I find a specific substation?

While there’s no way to search by substation, what you can do is navigate to the area on the map where the substation you’re after is located, then use the filters (substation kV and RAG status) to find the one you’re after.

Once you’ve got a list of potential options that meet your requirements, you can click onto each one for more information about it, to help you find the perfect site.

What do the different substation shapes mean?

There are four different shapes to represent four different types of substations.

  • Triangle: **400/132 kV (Grid):** Substation that generally receives 275kv or 400kv from the National Grid and transformed down to 132kv

  • Square: **132/33 kV (Bulk):** Intermediate substation generally where 132kV is transformed down to 33kV

  • Circle: **33/11 kV (Primary):** Intermediate substation generally where 33kV is transformed down to 11kV

  • Diamond: **<11 kV (HV) (UKPN only):** Intermediate substation generally where 11kV is transformed down to low voltage

You don’t have to remember all that – they’re all shown in the legend on the bottom left of the screen (you can click on it to expand/minimise it as you need to).

How do I export data about a specific substation?

Exporting information is really easy – just click onto the substation you’re after the info for, then click the 'Export data (.csv)' button on the right-hand side of the screen.

You’ll get all of the information the relevant DNO provides about the substation as a CSV file, to use however you need to.
