State Aid for Climate and Energy Projects
State aid for climate and energy projects is governed by the GBER, the CEEAG and, since June 2025, the Clean Industrial Deal State Aid Framework. Each route offers different speed, amounts and conditions. This guide explains how German decarbonisation projects are funded, and what beneficiaries must do to keep their aid secure.

Key takeaways
- The GBER allows aid without notification within thresholds; a revised GBER is planned for 2027.
- The CEEAG govern notified schemes and require incentive effect, proportionality and often bidding.
- The CISAF applies from 25 June 2025 until 31 December 2030 with simplified routes.
- Starting works before applying usually destroys the incentive effect and the aid.
- Unlawful aid can be recovered with interest, so beneficiaries must check the legal basis.
State aid for climate and energy projects: the short answer
State aid for climate and energy projects in Germany is assessed under three sets of EU rules. The General Block Exemption Regulation (GBER), Regulation (EU) No 651/2014, allows Member States to grant aid within defined limits without prior Commission approval. The Guidelines on State aid for climate, environmental protection and energy (CEEAG), applicable since 2022, govern notified aid such as large decarbonisation schemes, renewable energy support and network measures. And the Clean Industrial Deal State Aid Framework (CISAF), adopted on 25 June 2025 and in force until 31 December 2030, offers simplified routes for clean energy rollout, industrial decarbonisation, clean-tech manufacturing, electricity cost relief for energy-intensive users and de-risking instruments.

For companies, the choice of legal basis determines how fast aid can be granted, how much can be granted and which conditions apply, from competitive bidding to clawback mechanisms. This article explains each instrument from the perspective of a German company planning a decarbonisation or energy project, and the practical points that decide whether funding is secure. The GBER itself is under review: the Commission plans to adopt a revised GBER by the end of 2026, with entry into force on 1 January 2027.
Why state aid rules matter for climate projects
Any advantage granted by the state or through state resources to undertakings that can distort competition and affect trade between Member States is state aid under Article 107(1) TFEU. Grants, subsidised loans, guarantees, tax reductions, carbon contracts for difference and feed-in premiums typically qualify. Such aid may only be granted after Commission approval (Article 108(3) TFEU) unless a block exemption applies. Aid granted unlawfully can be recovered with interest, which is why beneficiaries must understand the legal basis of their funding.
In Germany, most programmes for state aid for climate projects are run by federal ministries, development banks and federal agencies such as BAFA. Each programme specifies its legal basis, typically a GBER article, an approved scheme under the CEEAG or, increasingly, a CISAF scheme. Funding guidelines (Förderrichtlinien) incorporate the EU conditions, including incentive effect, eligible costs, aid intensities and transparency.
The GBER: fast aid without notification
The GBER exempts categories of aid from notification if all general and specific conditions are met. Since its 2023 amendment by Regulation (EU) 2023/1315, which also extended its validity until 31 December 2026, the GBER contains extensive environmental and energy sections, including:
- investment aid enabling undertakings to go beyond EU standards or to increase environmental protection in the absence of standards;
- investment aid for energy efficiency and for the promotion of energy from renewable sources, renewable hydrogen and high-efficiency cogeneration;
- aid for decarbonisation of industrial activities, including electrification and hydrogen use;
- aid for recharging and refuelling infrastructure and for clean vehicles;
- aid for energy infrastructure and district heating and cooling;
- aid for environmental studies and for the remediation of contaminated sites.
Common conditions include an incentive effect (the application must be submitted before work starts), notification thresholds per undertaking and project, maximum aid intensities related to eligible costs, transparency obligations and the exclusion of undertakings in difficulty and of those subject to an outstanding recovery order. Aid above the GBER thresholds must be notified.
The incentive effect is the most common reason for loss of GBER aid. Do not sign binding orders for equipment or start construction before the funding application has been submitted. Preparatory studies and permits are generally not considered the start of works, but the definitions should be checked against the funding guideline.
The CEEAG: notified schemes and large projects
The CEEAG set out how the Commission assesses notified state aid for climate, environmental protection and energy. They cover, among other things, aid for the reduction and removal of greenhouse gas emissions (including renewable energy and industrial decarbonisation), clean mobility, resource efficiency and circular economy, security of electricity supply, energy infrastructure, district heating and cooling, and reductions from electricity levies for energy-intensive users.
The compatibility assessment follows a two-step test. First, the aid must facilitate the development of an economic activity, which requires an incentive effect and compliance with EU law. Second, the positive effects must outweigh the negative effects on competition and trade. In practice, the Commission examines necessity, appropriateness, proportionality and transparency. For decarbonisation aid, competitive bidding is generally required to allocate aid and determine its amount, and the funding gap must be quantified using a counterfactual scenario.
Germany's climate protection contracts (Klimaschutzverträge), which compensate the additional costs of climate-friendly industrial production compared with conventional processes, are an example of a CEEAG-based scheme using carbon contracts for difference and competitive bidding.
The CISAF: the 2025 framework for clean industry
The CISAF replaces the transition provisions of the Temporary Crisis and Transition Framework and applies from 25 June 2025 until 31 December 2030. It contains five types of measures.
| CISAF section | Purpose | Typical German use case |
|---|---|---|
| Accelerating clean energy rollout | Support for renewables and low-carbon fuels, with simplified tenders | Renewable or hydrogen production schemes |
| Electricity costs for energy-intensive users | Temporary relief from electricity costs, linked to decarbonisation investments | Industrial electricity price relief schemes |
| Industrial decarbonisation | Investment and operating aid to reduce emissions, including through electrification and hydrogen | Conversion of process heat or steel and chemicals production |
| Clean-tech manufacturing capacity | Aid for production of clean technologies and their key components and critical raw materials | Battery, electrolyser, heat pump or solar component factories |
| De-risking private investment | Equity, guarantees and other instruments to mobilise private capital | Funds or guarantee schemes for clean projects |
The Commission has published notification templates for each section and guidance on calculating gross grant equivalents and funding gaps. Compared with the CEEAG, the CISAF allows simpler aid calculations in some sections, for example fixed aid intensities instead of a full funding-gap analysis, which shortens design and approval of national schemes. It also allows support to be combined with requirements on resilience and on the origin of components where EU law permits.
Choosing the right basis for state aid for climate projects
From a company's perspective, the question is rarely which framework applies in the abstract, but which German programme fits the project and on which basis it was approved. Key differences:
- Speed. GBER aid can be granted without Commission approval once the national scheme is in place; notified CEEAG or CISAF schemes require approval first, but individual grants under an approved scheme do not.
- Amount. GBER notification thresholds cap individual aid; larger projects need notified schemes or individual notification.
- Allocation. CEEAG decarbonisation aid normally requires competitive bidding; CISAF and GBER allow certain direct grants.
- Conditions. Requirements such as clawback, energy audits, use of renewable electricity or reporting differ by instrument and are reflected in grant decisions.
- Cumulation. Aid from several programmes for the same costs must respect cumulation rules; EU funding such as the Innovation Fund is relevant for the calculation.
Large projects may also qualify as Important Projects of Common European Interest (IPCEI), assessed under a separate Communication, for example in hydrogen, batteries and microelectronics.
From application to grant: the typical procedure
Although the EU rules set the framework, companies deal mainly with German funding bodies. A typical procedure for a decarbonisation or energy investment runs as follows:
- Programme selection. Identify suitable federal and state programmes and check their legal basis, eligible costs, maximum aid and deadlines.
- Project outline. Many programmes start with a short project outline or expression of interest, followed by a full application.
- Application before start of works. Submit the application before binding commitments, documenting the counterfactual scenario where required.
- Bidding or evaluation. In competitive schemes, bids are ranked by criteria such as aid per tonne of CO2 avoided; in other schemes, the funding body assesses eligibility and the funding gap.
- Grant decision. The grant is awarded by administrative act or contract, with conditions on implementation, reporting, verification of emissions savings and clawback.
- Implementation and payment. Funds are paid against proof of costs or performance; deviations must be reported and may require approval.
- Monitoring. Reporting continues for years after completion, and audits by the funding body or courts of auditors are common.
Each step creates documents that later determine whether the aid can be retained, so applications, correspondence and change requests should be archived centrally. Companies should treat funding compliance as a project workstream with clear ownership, not as an administrative afterthought.
Transparency and reporting
EU rules require Member States to publish information on individual aid awards above certain thresholds in the Commission's transparency database, including the beneficiary's name, the aid amount and the purpose. Beneficiaries should expect their funding to be public. Grant decisions also impose reporting obligations on emissions reductions, production volumes and costs, and the CEEAG and the CISAF allow the Commission to request information on how schemes are applied. Misstatements in applications or reports can lead to revocation of the grant and, in serious cases, to criminal liability for subsidy fraud under § 264 of the Criminal Code.
Legal risks for beneficiaries
Beneficiaries carry the risk of unlawful aid. If a German programme granted aid beyond its approved scope, or a company did not meet the GBER conditions, the aid may have to be repaid with interest, even years later. Competitors can challenge aid before national courts and the Commission. Grant decisions often contain revocation and clawback clauses, for example where emissions savings or production targets are not met, and these are enforced under German administrative law.
State aid for climate projects also interacts with other regimes. Support may affect FSR assessments for non-EU-subsidised competitors, energy regulatory rules, emissions trading and procurement rules where public bodies purchase energy or technology. Project agreements, financing documents and supply contracts should allocate the risks of funding conditions and possible recovery.
Illustration: a hypothetical German glass manufacturer plans to replace a gas-fired furnace with an electric furnace. It applies for investment aid under a federal decarbonisation programme based on the GBER, before ordering the furnace. Because the aid would exceed the GBER threshold, the ministry instead offers support under a notified scheme with competitive bidding. The company models both routes, including the clawback mechanism if electricity prices fall below projections.

Frequently asked questions
What is the difference between the GBER, the CEEAG and the CISAF?
The GBER exempts certain categories of aid from notification if all conditions are met. The CEEAG set out how the Commission assesses notified environmental and energy aid. The CISAF, adopted in June 2025, provides simplified criteria for notified schemes supporting clean energy, industrial decarbonisation, clean-tech manufacturing and related measures until the end of 2030.
Can we start construction before receiving the grant?
Usually not without risk. Under the GBER and the guidelines, aid must have an incentive effect, which generally requires the application to be submitted before work starts. Signing binding equipment orders or starting construction before applying can make the project ineligible. Check the definitions in the specific funding guideline.
Do we need to take part in a competitive bidding process?
For many notified schemes under the CEEAG, especially decarbonisation aid, competitive bidding is the rule, because it reveals the aid actually needed. The CISAF and the GBER permit certain direct grants with fixed intensities. The German funding programme will specify the allocation mechanism.
What happens if the aid turns out to be unlawful?
If aid was granted without approval and outside a block exemption, or in breach of conditions, the Commission or national authorities may require recovery with interest. Competitors may also seek relief before national courts. Beneficiaries should check the legal basis and comply with all conditions.
Will the GBER change in 2027?
The Commission consulted on a draft new GBER from 25 February to 23 April 2026 and plans to adopt it by the end of 2026, with entry into force on 1 January 2027. Programmes based on the current GBER will need to be adapted to the new rules.
