No individual asset's hourly behaviour is measured.
The map locates reported asset records. It does not measure the hourly generation, charging, discharging or consumption of an individual asset.
European power assets
Map European power supply and demand
PowerUnits maps the supply side today: unit-level generation assets across Europe, with storage shown as a role in the map view. Demand assets are specified but not yet mapped — this page says exactly what exists and what does not.
The protected Units Map shows reported generation units by technology and status. Wind and solar layers are off by default to keep the map legible, so the default view is not the full fleet.
Demand in PowerUnits market surfaces is zonal or national state, not facility data, and it is not placed on map assets.
Definition
What a European power supply and demand map is
A European power supply and demand map places physical electricity assets and system-level load in a geographic frame while preserving the granularity and evidence type of each.
PowerUnits currently maps unit-level generation assets, with a supply/storage role filter in the map view. It does not map demand assets.
Zonal or national demand cannot be attributed to a named facility. A demand state measured for a country or bidding zone is not evidence of what happened at a factory gate.
Role taxonomy
Supply, storage and demand: what exists today
Supply, storage and demand are not interchangeable labels. The table records what the current product can show and the evidence type behind each role.
| Role | PowerUnits status | Evidence type |
|---|---|---|
| Generation assets | Mapped at unit level today | Reported asset records from Global Energy Monitor (GEM) |
| Storage | Shown as a role in the map view; not yet a modelled role in the data contract | GEM storage records and first-party UI taxonomy |
| Demand assets | Specified; not built and not mapped | Roadmap only — not available |
| Zonal or national load | Available in market surfaces; never placed on a facility | Country- or zone-level demand state, never an asset |
Evidence
Sources, attribution and unlocated capacity
The unit-level asset records come from Global Energy Monitor (GEM). Global Energy Monitor (GEM) data are licensed under CC BY 4.0.
Unit-level means one generating unit rather than a whole site. Reported capacity follows the source record without a guaranteed gross-or-net convention.
Capacity that cannot be geolocated is reported separately rather than hidden. For anyone reading an asset map, that means the map is a view of what could be placed, not an inventory of everything that exists in the source data.
Evidence boundary
Why zonal demand is not facility demand
PowerUnits has zero georeferenced demand assets. ENTSO-E demand in the repository is country- or bidding-zone state, never an asset.
Bidding-zone load is measured at the zone boundary, not at a factory gate. Placing a share of it on a facility icon would present something that was never observed.
The repository also has no bidding-zone polygons. Zonal demand therefore cannot be spatially derived and attributed to a named facility.
Coverage
Geographic and data coverage
Generation coverage follows the Global Energy Monitor source records and the coordinates that can be used. It is not a claim of complete plant or geographic coverage.
Capacity without usable coordinates is disclosed separately. Wind and solar layers are off by default in the workspace to keep the map legible, so the default view is not the full fleet.
Zonal or national load is available in separate market surfaces. It is not a demand-asset layer and is never placed on a facility.
Roadmap
What supply-and-demand mapping still requires
Reviewed on 2026-08-03: demand assets and storage as a separate modelled role are specified but not yet built.
As of 2026-08-03, the Power Asset Impact Explorer is an emerging analytical workflow that would connect physical assets to market analysis. It is not available.
Limitations
What the map does not show
Zonal demand is never attributed to a facility.
Country- or zone-level demand is system state, not evidence about a named site.
The default view is not the full fleet.
Wind and solar layers are off by default in the workspace to keep the map legible.
Capacity semantics follow the source record.
Reported capacity has no guaranteed gross-or-net convention, and unlocated capacity is disclosed separately.
FAQ
Common questions
Where can I map European power supply and demand?
The protected PowerUnits Units Map maps the supply side through unit-level generation assets, with storage shown as a role in the map view. It does not currently map demand assets.
What is the difference between a unit and a plant?
A unit is one generating unit. A plant or site can contain more than one unit, so unit-level records should not be read as one row per whole site.
Does the map show electricity demand?
No. PowerUnits has zero georeferenced demand assets. Zonal or national load exists in separate market surfaces and is never attributed to a named facility.
Where does the asset data come from and can it be reused?
The unit-level asset records come from Global Energy Monitor (GEM). Global Energy Monitor (GEM) data are licensed under CC BY 4.0.
Why is some capacity missing from the map?
Some reported capacity has no usable coordinates. PowerUnits reports that unlocated capacity separately rather than hiding it, because an asset map can show only records that can be placed.
How do power assets affect electricity markets?
PowerUnits does not currently quantify an individual asset's market impact. The Power Asset Impact Explorer is the emerging workflow intended to address that question, and it is not available as of 2026-08-03.
