German Energy Law

The Energiewende Legal Framework

Germany’s Energiewende (energy transition) is the central organising principle of German energy law, seeking to achieve a decarbonised, nuclear-free, and increasingly decentralised energy system. The legal framework is anchored in a patchwork of statutes — the Erneuerbare-Energien-Gesetz (EEG) , the Energiewirtschaftsgesetz (EnWG) , and the Atomgesetz (AtG) — together with European Union law transposition and Land-level implementation. The German Federal Constitutional Court (Bundesverfassungsgericht) has shaped energy law through decisions including the Atomausstieg (Nuclear Phase-Out) judgment (BVerfG, 6 December 2016) and the Climate Protection judgment (BVerfG, 24 March 2021), which required legislative specification of post-2030 emission reduction targets.

Erneuerbare-Energien-Gesetz (EEG) 2023

The EEG was first enacted in 2000 and has been amended repeatedly to scale up renewable energy deployment while controlling costs. The EEG 2023 (in force 1 January 2023) sets a target of 80% renewable electricity by 2030 and 100% by 2035 in the electricity sector — though the 2035 target was later modified. The EEG establishes a feed-in premium system in which renewable energy generators receive a market premium on top of wholesale electricity revenues, determined through competitive auctions for solar, onshore wind, offshore wind, and biomass. The degression mechanism, which previously reduced support levels annually, has been replaced by auction-determined prices.

The EEG 2023 designates renewable energy as being in the overriding public interest and serving public security, significantly strengthening the legal weight of renewables in planning and permitting decisions. The Act also establishes REPowerEU-aligned expansion corridors: 215 GW of solar capacity and 115 GW of onshore wind by 2030, with annual installation rates of 22 GW (solar) and 10 GW (onshore wind). The WindSeeG (Wind Energy at Sea Act) separately governs offshore wind expansion, targeting 30 GW by 2030 and 70 GW by 2045.

Bundesnetzagentur (BNetzA) Role

The Federal Network Agency (Bundesnetzagentur, BNetzA) is Germany’s independent regulatory authority for electricity, gas, telecommunications, post, and railway infrastructure. Under the EnWG, the BNetzA regulates network access, network charges (grid tariffs), connection conditions, and unbundling requirements, ensuring non-discriminatory access to energy networks. The BNetzA also oversees the capacity mechanism (network reserve, capacity reserve, and the § 13 EnWG emergency measures), conducts auctions for renewable energy support under the EEG, and supervises grid expansion plans. The BNetzA’s decisions are subject to appeal to the Oberlandesgericht (Higher Regional Court) in Düsseldorf.

Energiewirtschaftsgesetz (EnWG)

The Energy Industry Act (EnWG) of 2005 (as amended) transposes the EU internal energy market directives and governs the general legal regime for electricity and gas supply. The EnWG establishes: the principles of safe, affordable, consumer-friendly, efficient, and environmentally compatible energy supply (§ 1); unbundling of network operators from generation and supply activities; regulated network access (third-party access); and network development plans (NEP — Netzentwicklungsplan). The EnWG was significantly amended in 2023 to implement the EU Clean Energy Package, including provisions on citizen energy communities, aggregation, demand-side flexibility, and dynamic electricity pricing for final consumers.

Nuclear Phase-Out (Atomausstieg)

The Atomgesetz (Atomic Energy Act), AtG, originally enacted in 1959, has been amended repeatedly to effect Germany’s nuclear phase-out. The Atomausstieg was first legislated in 2002 under the Schröder government (AtG amendment 2002), then reversed in 2010 (extending reactor lifetimes), and finally reinstated after the Fukushima disaster in 2011 — the 13th AtG amendment (2011) immediately shut down eight reactors and set 31 December 2022 as the final shutdown date for the remaining six. The Bundesverfassungsgericht upheld the 2011 amendment in 2016, finding it constitutional but requiring compensation for investment losses. The remaining three reactors — Isar 2, Emsland, and Neckarwestheim 2 — were shut down on 15 April 2023, after a brief winter stretch operation. The nuclear waste disposal regime is governed by the Standortauswahlgesetz (Site Selection Act) of 2017, establishing a participatory process to identify a final repository for high-level radioactive waste by 2031.

Emissions Trading and CO2 Pricing

Germany is part of the EU Emissions Trading System (EU ETS) for power generation and industry, and operates a national Fuel Emissions Trading Act (Brennstoffemissionshandelsgesetz, BEHG) covering heating and transport fuels not included in EU ETS. The BEHG establishes a national CO2 price that rose from €25/tCO2 in 2021 to an upper corridor of €55–€65/tCO2 by 2026. The Kohleausstiegsgesetz (Coal Phase-Out Act) of 2020 sets a binding phase-out date for coal-fired power generation by 2038 at the latest, with a review clause for 2035. Hard coal plants were subject to a competitive tender process for early closure payments, while lignite plants follow a scheduled closure pathway with compensation agreements for operators.

Grid Expansion (Netzausbaubeschleunigungsgesetz)

The Grid Expansion Acceleration Act (Netzausbaubeschleunigungsgesetz, NABEG) of 2011, comprehensively amended in 2019 and 2023, streamlines planning and permitting for high-voltage transmission lines, particularly the SuedLink, SuedOstLink, and Ultranet North–South corridors needed to transport wind power from northern Germany to industrial load centres in the south. The Bundesbedarfsplangesetz (BBPlG) identifies specific projects in the federal need plan, with the need determination being binding on planning authorities. The NABEG 2023 introduced acceleration measures including shorter public consultation periods, digital planning procedures, and prioritisation of underground cabling for DC links. The Thorium and Nuclear Power controversy remains alive in the political sphere but has no immediate legislative impact on the legal framework.
