As part of Tranche 3, TenneT will publish the reconciliation prices on www.tennet.eu and via APIs. Prices for January will be available from 17 February. Until then, only the API with the monthly prices contains data. The other APIs currently still give an empty result. The historical reconciliation prices without a tariff period will become available around 7 February. This one-time process is partly carried out manually.
The intention was actually to activate the APIs only shortly before February 7. But this raised questions among parties who invoked the APIs prematurely. To this the APIs automatically reply that they are unavailable. In the hope that empty APIs will raise fewer questions, TenneT has brought forward the activation moment.
The manual and the API specs for both the reconciliation prices and the source data are available on MyTenneT, in the Onboarding & IT app.
