Why data centres matter to the construction market
Data centres are some of the largest construction projects being built today. A single campus can need hundreds of megawatts of power, new substations, cooling plants, backup generation, fibre and years of fit-out work. For electrical contractors, mechanical contractors, steel and concrete suppliers, cooling manufacturers and staffing firms, knowing where these projects are planned is worth more than almost any other lead.
The problem is that information is scattered across press releases, planning portals, grid connection queues and industry lists. Mapenzo brings it onto one map, next to building permits and energy projects, so you can see the full picture of an area.
What is on the map
- 4,323 existing data centres. Operating facilities, visible with the "Show existing" filter.
- 281 confirmed planned data centre projects. Announced projects, sites in permitting and campuses under construction.
- 327 further projects under review. These are still being verified and are not counted in the 281.
- Over 33,000 energy projects on a separate layer, including solar, wind, storage and grid projects, so you can see where power for new data centres will come from.
To be clear about numbers: "around 4,000 data centres" refers to existing sites. Planned projects are a smaller, faster-changing list, and we only count confirmed ones.
How contractors and suppliers use it
Find the next campus early. Planned projects appear long before the main construction contracts are awarded. Electrical and mechanical subcontractors can identify the developer and general contractor while the supply chain is still forming.
Understand clusters. Data centres cluster around fibre routes, power and tax incentives. Seeing existing sites on the map shows you where the next ones are likely to be, and where service and maintenance work already exists.
Combine with permits. Around a large campus you will see related building permits: substations, warehouses, housing for workers, road works. In Europe, open the country pages for Ireland, the Netherlands or Finland and look at permits near data centre clusters. In the US, local permit data in areas such as Norfolk, Virginia and Chicago sits on the same map.
Combine with energy projects. A planned data centre near a planned solar farm or grid upgrade is a strong signal for electrical contractors.
Who else uses it
Investors and site-selection consultants use the map to compare regions. Utilities and grid planners see where demand is coming. Local authorities can see what is planned around them. Recruiters and training providers can see where skilled electricians will be needed.
How to start
- Open the map and switch on the data centre layer.
- Use "Show existing" to see operating sites, then switch to planned projects.
- Turn on the energy layer to see generation and grid projects nearby.
- Zoom to a region and open the building permits around a cluster.
- Save the view and check monthly; planned projects change often.
Limits
Planned projects are based on public announcements and filings, and dates often move. Each record shows its source so you can check it. We do not count projects still under review.
Try it
Mapenzo has a simple way to test this: a 12-hour pass for 5 € opens every country, every permit and every layer, including energy projects and data centres. If you then subscribe, your first month is 50% off. Personal plans are 20, 50 or 80 € per month, and Team plans for sales teams are 40, 100 or 150 € per month.
