When German renewables go merchant: the asset-level subsidy cliff

1,201 German assets — 7,935 MW — lose EEG support by the end of 2030, and 686 more roll off in 2032 alone. The dates are per-asset, not modelled.

§25 EEG 2023 grants support for 20 years plus the year of commissioning. So a plant commissioned on any day in 2010 is supported to 31 December 2030 and fully merchant from 1 January 2031.

That makes the expiry year a fact rather than an estimate — provided you have the commissioning date. Asset databases generally carry a commissioning year, which fixes the decade and not the year. The German registry publishes the date.

German assets losing EEG support, by year

Last year of support. Each asset is merchant from the following January. The 2032 peak is the 2011–2012 solar build-out reaching the end of its 20-year tenor.

The wave peaks in 2032 at 686 assets and 2,648 MW — the 2011–2012 solar build-out reaching the end of its tenor. Anyone originating PPAs or buying secondary assets in Germany is looking at a pipeline of counterparties that is knowable years ahead, by name.

Why this is not the whole picture

The statutory tenor is a calculation. What an asset actually did is a measurement, and the two disagree more often than you would expect.

744 German assets were already selling outside EEG support in 2024, and their median commissioning year is 2022 — decades from any expiry date. They opted into unsupported direct marketing rather than ageing out. Screening purely on tenor would miss all of them.

Where measured settlement shows an asset already merchant, that observation should win over the calculated date. On this platform the calculated year is suppressed in exactly that case, rather than printing both and letting the reader reconcile them.

Method and limits

  • Source: EEG-Anlagenstammdaten, the registry file the four German TSOs publish alongside the settlement data. 3,908,164 installations, 99.9% carrying an exact commissioning date.
  • Join: EEG_Mastr_Nr, the same key as the settlement data, through MaStR to plant-level asset records. 6,024 assets joined; 5,936 carry a usable expiry year.
  • Validation: 96.6% of registry commissioning years agree with the independently researched year in the asset database within ±1 year, median difference 0.
  • It is a calculation, not an observation. A plant can leave support early by opting into direct marketing, and a phased site rolls off in stages — both are carried separately rather than averaged.
  • Retirement is not modelled. Only 0.7% of assets carry a retirement date, so nothing here should be read as a forecast of installed capacity.
