Generator registers
EU law obliges every country to keep a public register of combustion plants from 1 to 50 MW: generator sets, boilers and turbines (Directive 2015/2193, Article 5). We read these registers country by country and tie each plant to its operator and its site.

Sites in operation or under construction. The national database holds the sites under authorisation and registration; smaller sites under simple declaration are mostly not in it, so totals are lower bounds. Values that look like unit errors are left out of the thermal total. Data-centre sites are found from the operator's activity code and name.
The full list for a country
One line per plant: operator, site address, plant type, thermal input, planned running hours, status and registration number, with a link to the register. Companies only. CSV, €490 per country.
Who uses it
- Generator dealers and service firms
- Every engine of 1 MW and more, with its operator, its site and its running hours.
- Fuel and HVO suppliers
- The sites that store and burn diesel, sized by thermal input.
- Emission testing and abatement
- Each plant's type, thermal input and planned hours: the figures the directive's limits depend on.
