PUE 1.2, staged waste heat use, 100 percent renewables from 2027. And why water is not the bottleneck in practice.

Terawerk. Site development for data centers.
Power, land, permits.
Terawerk develops large data center sites in Germany to shovel-ready: grid connection, land, permits, energy, heat and fibre. We do not build. We hand over to the operator that fits the site.
- Data center capacity in Germany in 2026, federal target 5 GW by 2030.
- 3 GW
- Earliest date for new large grid connections around Frankfurt.
- Mid 2030s
- Cost of congestion management in the German grid in 2025.
- 3.1 bn EUR
- Federal government target for data center capacity in Germany.
- Doubling by 2030

What we believe
- Read the Insight
The next chip generation needs gigawatts.
Much of what is being built in Germany today is planned in the megawatt range. The next data center generation needs gigawatt-scale sites.
Compute needs sites in the country.
Anyone who wants to run models in Germany needs sites in Germany.

The site follows the power.
Grid connection and land decide, not proximity to Frankfurt.
Compute belongs where the power is generated. Not where the grid is full.
What we deliver
Grid connection
We run the application in the transmission system operators' Reifegradverfahren (maturity procedure): technical connection concept, land security, proof of financing, flexibility offer.
Result: a documented 380 kV connection path.
Land and permits
We secure contiguous land at transmission nodes via options and run the process for a Sondergebiet Rechenzentrum (special-use zoning for data centers) together with municipality, district and state politics.
Result: building rights.
Energy and heat
We combine direct supply from wind and solar, storage at the connection point and waste heat use under the EnEfG (Energy Efficiency Act).
Result: an energy and heat concept that operators and grid operators accept.
Dark Fiber
We review the routes and the connection to the carriers' backbone nodes.
Result: a documented, redundant fibre path to the site.
What defines us
We are not a broker and not an operator. We know the buyers because we sit in their market. We know the grid because we come from the German energy industry. And because we do not build ourselves, we can hand each site to the operator that brings it online fastest.
Comparison: broker, developer, utility, Terawerk | Broker | Developer with own balance sheet | Utility | Terawerk |
|---|---|---|---|---|
| Knows demand from the US market | no | partly | no | Yes |
| Does not build, no conflict of interest | yes, without substance | no, own portfolio | no, own grid area | Yes |
| Depth in the German energy market | no | partly | yes | Yes |
| Develops the pre-stage (grid, land, permits, energy) | no | for itself | no | Yes |
| Several operators on one site | no | no | no | Yes |

For municipalities and the state
What a campus means for a municipality: jobs in construction and operation, local investment, training of skilled workers, trade tax, waste heat for the region. And what we ask of municipality and state.
