Opening screen of the Transmission Heat Map, as it sits on the website. 
| Welcome!
This video will guide you through the key features of the ScottishPower Transmission (SPT) Heatmap — a powerful, interactive tool showing projects across our licensed network area. The heatmap draws data from the National Electricity System Operator’s Transmission Entry Capacity register. It gives a clear view of current and future projects, their technologies and capacities — helping you assess opportunities and challenges when connecting to the transmission system. |
Select the box on the Left hand side and pin it on the screen. And show selecting of demand and changing the ‘distribution substation’ from ‘None’ to ‘GSP’ on the left side. | In December 2024, we enhanced the map to include demand projects. To view these, simply select the “Transmission Demand” option on the left-hand side. Please note: it shows contracted demand projects only — not those already connected. You can also add Distribution Grid Supply Points (GSPs) to enrich the view. |
Mouse hovers over the capacity information in the top right corner, with each box highlighted when it is being talked about. | On the top right, you can key statistics “Transmission Connected” shows the capacity in MW of the projects that are currently connected to our network, “Increase/Decrease” shows the MW’s of projects that are contracted. The “cumulative total capacity” shows the total capacity that will be on SPTs network in the future. |
Little circles and diamonds being highlighted on the Heat Map, scrolling through the Legend on the right hand side when talking about legend. | Now let’s look at the map itself. It includes coloured circles and icons in different sizes, which represent the Transmission Generation and Demand projects. You can see different sized circles on the map representing the different capacities for the transmission projects, that is the larger the size of bubble the larger the import capacity of the project. You can note demand projects by their red circles with a white downward facing arrow and generation projects by their different colours, the key for which can be found under the ‘legend’ in the column on the left. |
Zooming into the map to find distribution projects. | You can also see the distribution generation projects which are denoted by a small triangle, the colours of these vary slightly from the transmission generation so be sure to check the individual project notes. We also have grid supply points on this map that are noted as small, coloured diamonds, these follow a traffic light colour system colour-coded by available export capacity with green being over 50% while amber denotes the Grid Supply Points (GSPs) with 20 to 50% and finally the red diamonds demonstrating those with less than 20% remaining total export capacity. |
The Overhead lines being highlighted on the map and highlight the legend column when saying the last line. | we also have our overhead transmission lines on the map, different colours represent different voltage levels. The key for all the different colours and sizes can be found in the ‘legend’ column here on the right. |
Mouse clicks through the filters along the top, from left to right, aligning with the voiceover | Moving on, along the top of the map we have a variety of filters that can be applied. These filters are only applied to transmission generation projects. Here you can filter for project status, project type, specific project sub-status the effective from date, and if you have a specific project in mind you can use the project search function to look it up. |
Mouse moves to the left hand side panel and scrolls through different options, highlighting each with the script.
| On the left-hand side you can refine your distribution search by selecting your preferred GSP(s) and even search for a particular embedded project on the Embedded Capacity Register (ECR) register. |
Zooms into map, finding a section that has a variety of types of projects, first clicks on a transmission generation project (selects large circle) | Now that we have covered the basics, let's explore the map further. Clicking on an individual item, pulls up an additional information box which will show you more information on that project. The information shown differs depending on the item. |
After selecting the circle, information box appears | For transmission generation projects, you can see the name, connection site, project status, the effective from date which is the current final energization date and a whole variety of other information. |
Back to map, selects red circle | For a demand project you will see the name of the project, contract status, connection site and the import capacity in MW’s. |
Back to map, selects a small triangle, | Selecting a distribution connection, you will see information such as the project name, substation connection, the connection status, the energy capacity in MWs and the energy source. |
Selecting the layers tab, mouse clicks through the different layers turning them on and off, before turning them all back on, choose different options here | To further focus on the information you need, you can play with layers. This button allows you to see and select a variety of layers within the map. You can turn on and off the view of various generation or demand projects, substations and circuits. This allows you to personalise this map based on your needs. |
User demonstrated the selection tools on the left side, using various selection tools on areas across the map, then showing the differences it causes. | Finally, the spanner icon unlocks Drawing tools including the lasso tool which allows you to select a small section of the network Once the area is drawn the map will then highlight every asset within that area. You may notice the values on the top right changing according to your selected area. These values have been re-calculated for the transmission projects within your selection range. If you're looking to apply filters to a specific area, you should apply the filters before selecting your area of the network. |
Transmission Heat Map zooms out of the screen and SPT Logo and background displays on the screen. | That’s a quick tour of the SPT Heatmap.
While it doesn't replace detailed connection studies, it's a great tool to aid in initial assessments and identifying network hotspots. We hope that this video has helped you understand the vast functionalities of this tool and ultimately assist you in strategically planning your future projects. Thanks for watching. |
