Grid capacity map: substations and the room left to connect
Grid access decides where projects can be built and when. Sherpa Atlas maps the high-voltage substations country by country and colours each by what its grid operator or regulator has published: the room left to connect new load or generation, or the demand already asked of it, with the upgrades and statements that name it.
What the map shows
Substations and grid capacity, with everything that decides a project around them
Substations by voltage
Transmission and high-voltage distribution substations, with operator, voltage and area.
Published grid status
Room to connect where the operator states it; the demand already requested of the grid where that is what is published. Always the operator’s own figure, with its date.
Upgrades and statements
Grid reinforcements and new substations from the operators’ plans, and what operators, regulators and governments have said about capacity.
Demand and supply around it
Data centres, plants and projects near each substation, with power fed in and power drawn shown apart.

Every record with its sources and date
Each grid capacity record opens in full: status, capacity as stated, owners, the grid around it and every source, dated. Search any place, site, company or coordinates.
Who uses it
How teams use the grid capacity map
Developers of data centres and large loads
Find substations with room to connect, and see where the demand already asked of the grid makes a connection unlikely before a site is optioned.
Renewable and storage developers
Compare areas by the generation already planned and the room left for more, and follow the upgrades that will open new capacity.
Investors and lenders
Test whether a project’s connection date and grid assumptions hold against what the operator has published.
Grid operators, utilities and consultants
See where demand and generation requests concentrate across operator boundaries, on one map.
Land and real-estate advisers
Qualify land by its distance to a substation with published capacity before marketing it for power-hungry uses.

Questions
The grid capacity map: questions
What does the grid capacity map show?
High-voltage substations coloured by what their grid operator has published: the room left to connect, or the demand already asked of the grid, with grid upgrades, statements and the projects around them.
Does it show available capacity or demand?
Whichever the operator publishes. Where operators state the room left to connect, substations are coloured green to red by that; where they publish the demand requested, by that demand. Each figure is the operator’s own, unaltered and dated.
Where does the data come from?
Every record carries its sources and the date it was last checked: grid operators, regulators and governments, planning authorities, company announcements and the press. Nothing is estimated where a figure has been published; where no figure is published, the record says so.
