Germany has a well-established and rapidly growing renewable energy sector, supported by a robust legal framework at both the national and EU levels. A cornerstone of this framework is the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG), first adopted in 2000 and most recently amended in 2023. A further reform of the law is planned for 2027 and a draft bill by the Federal Ministry for Economic Affairs and Energy (Bundesministerium für Wirtschaft und Energie, BMWE) is currently being discussed within the Federal Government. The Renewable Energy Sources Act guarantees priority access to the power grid for renewable energy sources and includes financial mechanisms to promote their development. Compliance is aligned with Directive (EU) 2018/2001 (Renewable Energy Directive II, RED II) as amended by Directive (EU) 2023/2413 (RED III) and the Federal Climate Change Act (Bundes-Klimaschutzgesetz, KSG), which sets binding greenhouse gas reduction targets.

Germany’s renewable energy portfolio is broad and diverse:

• Onshore Wind Energy: Currently around 68,2 GW of installed capacity, with a target of 115 GW by 2030 under the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG).
• Offshore Wind Energy: Installed capacity of 9.7 GW, with legally binding targets of 30 GW by 2030 and up to 70 GW by 2045 under the Offshore Wind Energy Act (Windenergie-auf-See-Gesetz, WindSeeG).
• Photovoltaics (PV): Approximately 117.9 GW currently installed; the 2030 target is 215 GW.
• Biomass and Biogas: Around 9.0 GW, primarily used in combined heat and power plants (Kraft-Wärme-Kopplung, KWK).
• Hydropower: Roughly 5.9 GW, mostly from small-scale plants with limited expansion potential due to geographic constraints.

Project sizes in the renewable energy sector range from utility-scale offshore wind farms (e.g. “Baltic Eagle”, “Gode Wind”) and large photovoltaic parks to decentralized generation systems such as rooftop PV installations and agricultural biogas plants. Germany is also a pioneer in large-scale battery storage and green hydrogen projects, with significant expansion under the updated National Hydrogen Strategy (2023/2024) and increasing focus on import infrastructure and electrolyser capacity.

In 2025, electricity generation from renewable sources in Germany reached approximately 278TWh, which corresponds to about 55,9% of the net public electricity generation, roughly the same level as in the previous year. Renewable energies thus remained the most important source of electricity supply in Germany. Wind power continued to be the largest contributor, generating about 132 TWh, despite a year‑on‑year decline of 3.2% due to less favorable wind conditions. Of this, around 106 TWh came from onshore wind and about 26.1 TWh from offshore wind.
.
Photovoltaic systems recorded strong growth, producing around 87 TWh of electricity – an increase of 21% compared to 2024. Approximately 71 TWh were fed into the public grid, while 16.9 TWh were self‑consumed by producers, reflecting the rapid expansion of decentralised PV systems.
Electricity generation from biomass rose to about 41.1 TWh, while hydropower declined to around 17.8 TWh due to significantly lower precipitation. Overall, renewable electricity generation increased slightly compared to 2024 but still fell well short of the expansion target of 346 TWh set for 2025, mainly because wind power expansion – especially onshore – remained below planned levels.

Generation from conventional energy sources stagnated, with a decline in lignite‑based generation largely offset by increased electricity production from natural gas. Nuclear power played no role, having been fully phased out in April 2023.

Germany’s climate targets are not merely political declarations. They were first codified in the Federal Climate Protection Act (Bundes Klimaschutzgesetz, KSG) adopted in December 2019. The Act was last amended in July 2024. While the amendment did not alter the legally binding long term mitigation targets, it replaced binding annual sectoral emission budgets with a cross sectoral, multi year assessment framework, thereby increasing flexibility across sectors.

The statutory climate targets remain:

• 65% reduction in greenhouse gas emissions by 2030 (compared to 1990 levels)
• 88% reduction by 2040 (compared to 1990)
• Net-zero emissions by 2045, with net-negative emissions after 2050

In addition, in March 2025, the German constitution, the Basic Law (Grundgesetz, GG), was amended to allow for additional debt of up to 500 billion euros for additional investments in infrastructure, defence, and climate transformation.

This further strengthened Germany’s commitment to net neutrality, underscores the nation’s dedication to climate action, and enhances the legal standing of its climate targets.

Section 3 (Definitions) of the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG) defines renewable energy as energy produced from renewable sources such as: wind energy (onshore and offshore), solar energy (photovoltaic and concentrated solar power), biomass (including biogas, solid biomass, and liquid biomass), hydropower (from flowing water), or geothermal energy (heat derived from within the Earth).

The energy transition in Germany is largely shaped at the federal level, with the federal government (Bundesregierung) as the most important decision maker. The Federal Ministry for Economic Affairs and Energy (Bundesministerium für Wirtschaft und Energie) is the central player in energy policy and legislative initiatives. It is supported by the Bundestag and, in particular by Committee on Economic Affairs and Energy (Ausschuss für Wirtschaft und Energie). Climate protection policy and emissions reduction targets are primarily within the remit of the Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety (Bundesministerium für Umwelt, Klimaschutz, Naturschutz und nukleare Sicherheit), including responsibility for the Federal Climate Protection Act (Bundes‑Klimaschutzgesetz, KSG) and its binding CO₂ reduction targets.
The Federal Network Agency (Bundesnetzagentur, BNetzA) acts as the national regulatory authority in the energy sector. It regulates access to the electricity and gas grids, organizes tenders for wind and solar power plants pursuant to the Renewable Energy Act (EEG), and ensures fair competition.

The Federal Environment Office (Umweltbundesamt) provides scientific and technical expertise on environmental impacts, while the German Energy Agency (Deutsche Energie-Agentur, dena) provides strategic advice on the energy transition. The KfW Bank (Kreditanstalt für Wiederaufbau) promotes investment in renewable energies through low-interest loans and grants.

In addition, many private sector players are actively driving the energy transition in Germany. Leading energy companies (including RWE, EnBW and E.ON) are strategically repositioning themselves and investing heavily in wind, solar, and storage projects. RWE, for example, has transformed itself from a lignite company into one of Europe’s largest developers of offshore wind farms. EnBW is planning a massive expansion of solar and wind power, particularly in southern Germany. E.ON is focusing on modern network infrastructure, digital energy services, and smart energy solutions for private homes – including solar systems and EV charging stations.

Companies in Germany are pursuing different approaches to gaining access to renewable energies, depending on their size, industry, and strategic orientation. One of the simplest and most widespread measures is to purchase certified green electricity from an energy supplier. This step requires little administrative effort, can be implemented at short notice, and is particularly attractive for small and medium-sized companies. For example, the outdoor company VAUDE (a German manufacturer of outdoor equipment) uses 100% green electricity for its headquarters, which makes a key contribution to its climate strategy.

More complex, but also more effective, are corporate power purchase agreements (cPPAs) – long-term electricity supply contracts with renewable energy operators. Such contracts offer planning security for energy prices and at the same time promote the expansion of new plants, especially those without Renewable Energy Act (Erneuerbare-Energien-Gesetz, EEG) subsidies. In practice, both physical and virtual PPAs are used, typically with contract durations of 5 to 15 years. The technology group Bosch, for example, has signed a PPA with the energy company RWE to purchase electricity from a solar park built specifically for this purpose.

A third approach is to generate electricity in-house using photovoltaic or, less commonly, wind power systems on company-owned land such as roofs or parking lots. This solution offers long-term cost advantages and increases independence from price fluctuations on the energy market. The Selatec GmbH & Co. KG, a medium-sized machine manufacturer, already generates around 30 % of its electricity requirements in this way.

Yes, the business approach to renewable energy in Germany has noticeably evolved over the last year. Key drivers include continued ESG and sustainability reporting obligations (particularly under the EU Corporate Sustainability Reporting Directive, CSRD), persistent concerns about energy security following the disruption of Russian gas supplies, and volatile wholesale electricity prices.

The German government has accelerated permitting procedures through the Wind Energy Area Requirements Act (Windenergieflächenbedarfsgesetz, WindBG), first adopted in 2022 and most recently amended in August 2025, and through amendments to the Federal Immission Control Act (Bundes-Immissionsschutzgesetz, BImSchG) in 2024, designating renewable energy projects as being in the overriding public interest.

Key developments in the last 12 months include record solar PV installations (approximately 15 GW of new capacity in 2025), the continued ramp-up of offshore wind auctions, growing investment in green hydrogen infrastructure, and the expansion of battery energy storage systems (BESS) projects. Additionally, the introduction of carbon contracts for difference (CCfDs) for industrial decarbonisation has further incentivised corporate engagement with renewables.

The debate about reducing CO₂ emissions and improving energy efficiency is now very visible in the German economy. In many business sectors – especially in the energy and industrial sectors – climate protection is an integral part of strategic decision-making. Companies are increasingly recognizing that investing in CO₂ reduction is not only necessary for the environment but also makes good business sense. However, there are differences between sectors: While the energy industry is making great strides thanks to the massive expansion of renewable energy, the transportation and building sectors, for example, still have a long way to go.

Politically, the transition is being supported by numerous measures: The national CO₂ price, the German Climate Protection Act (Bundes-Klimaschutzgesetz, KSG) with binding reduction targets and targeted support programs (e.g. for industry, buildings or hydrogen projects) create a fundamentally sound framework.

The EU is also exerting a strong regulatory influence with its “Fit for 55” package as part of the EU Green Deal and emissions trading. However, companies complain about red tape, high energy costs, and uncertain political conditions, which often make implementation difficult. In addition, a key challenge in 2026 is the implementation burden from overlapping EU rules (CSRD, EU taxonomy, ETS2 preparation, CBAM reporting), which significantly increases administrative requirements, especially for industrial SMEs and supply chains.

In Germany, rights to develop renewable energy projects are granted through a combination of spatial planning, permitting, and auction processes. Research, construction, and operation of energy projects are subject to strict legal regulations. The specific permits required will always depend on the type, size and location of the project. Grid interconnection is regulated by the Energy Industry Act (Energiewirtschaftsgesetz, EnWG), with transmission system operators (TSOs) and distribution system operators (DSOs) obligated to connect renewable installations.

• Solar and onshore wind projects typically require private land contracts and building permits (Baugenehmigung), and in some cases environmental impact assessments (Umweltverträglichkeitsprüfung).

• Offshore wind farms are awarded through tenders in designated zones. There are extensive requirements in terms of spatial planning, environmental and safety standards.

• Geothermal and CCS projects are subject to mining and water law requirements. Depending on depth and location, different authorities are involved; environmental impact assessments (Umweltverträglichkeitsprüfung) and nature conservation requirements (Naturschutzauflagen) apply. CCS is regulated under the Carbon Dioxide Storage Act (Kohlendioxid-Speicherungsgesetz, KSpG), though deployment remains limited and politically contentious in Germany

• Hydropower projects require water law approval (wasserrechtliche Genehmigung) and a building permit (Baugenehmigung). An environmental impact assessment (Umweltverträglichkeitsprüfung) is also usually mandatory.

• Biomass and biogas projects usually require a building permit (Baugenehmigung) and in most cases an immission control permit (Immissionsschutzgenehmigung).

• Combined heat and power (CHP) plants usually require a building permit (Baugenehmigung) and sometimes a permit under the Federal Immission Control Act (Bundesimmissionsschutzgesetz, BImSchG). CHP plants are supported under the Combined Heat and Power Act (Kraft-Wärme-Kopplungsgesetz, KWKG), which provides feed-in bonuses and incentives.

• Battery storage systems generally require a building permit (Baugenehmigung); depending on their size and type, additional permits may be required, e.g. under the Federal Immission Control Act (Bundesimmissionsschutzgesetz, BImSchG).

• Hydrogen projects are subject to various permitting requirements depending on their type and scope, in particular under the Federal Immission Control Act (Bundesimmissionsschutzgesetz. BImSchG) and the Ordinance on Industrial Safety and Health (Betriebssicherheitsverordnung, BetrSichV). The permitting framework depends on the production method (electrolysis, steam methane reforming with CCS).

• Due to the phase-out of nuclear energy, the focus is now on the decommissioning of existing facilities. The decommissioning, safe enclosure, and dismantling of a nuclear power plant require a license in accordance with the German Nuclear Energy Act (Atomgesetz, AtG).

The German government plays a key role in the renewable energy sector by setting the regulatory framework, launching project tenders, and providing financial incentives. The expansion is mainly driven by the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG) through instruments such as technology-specific auctions, feed-in tariffs, and subsidy programs. The Federal Network Agency (Bundesnetzagentur, BNetzA) regularly puts large amounts of wind and solar capacity out to tender.

There are no dedicated state-owned renewable energy companies. The government holds temporary stakes in companies such as Uniper and SEFE, which were acquired primarily for energy security reasons. Their involvement in renewables is limited and not structured as a long-term renewable ownership strategy. These holdings are considered crisis-related interventions rather than industrial policy aimed at creating a state renewable champion.

Germany’s renewable energy sector is governed by a comprehensive legislative framework designed to support the transition to climate neutrality by 2045.

The primary support instrument is the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG 2023), which establishes the auction and market premium system for renewable energy installations and sets the overarching goal of a fully renewable electricity supply. The 2023 amendment – and further revisions from 2025 – placed increased emphasis on efficiency, cost-effectiveness, and the acceleration of planning and approval procedures, and explicitly prioritised renewable energy over competing interests in the decision-making process. A further reform of the law is planned for 2027 and a draft bill by the Federal Ministry for Economic Affairs and Energy (Bundesministerium für Wirtschaft und Energie, BMWE) is currently being discussed within the Federal Government.

Grid access and electricity market design are governed by the Energy Industry Act (Energiewirtschaftsgesetz, EnWG), which obliges transmission and distribution system operators (TSOs and DSOs) to connect renewable installations and provides the legal framework for network planning. The overarching climate targets are anchored in the Federal Climate Change Act (Bundes-Klimaschutzgesetz, KSG), which enshrines Germany’s binding commitment to greenhouse gas neutrality by 2045.

For onshore wind, the Wind Energy Area Requirements Act (Windenergie-Flächenbedarfsgesetz, WindBG, 2022) requires federal states to designate at least 1.4% of Germany’s land area for wind energy by 2027, rising to 2% by 2032. Complementary amendments to the Federal Nature Conservation Act (Bundesnaturschutzgesetz, BNatSchG) have streamlined species protection assessments nationwide. These measures – together with a federal-state Pact for Accelerated Planning agreeing 150 individual acceleration measures – contributed to a 50% increase in approved capacity in 2024 compared to the previous record year of 2016. Offshore wind development is regulated by the Offshore Wind Energy Act (Windenergie-auf-See-Gesetz, WindSeeG), which sets targets of 30 GW by 2030, 40 GW by 2035, and 70 GW by 2045, and simplifies procedures in pre-assessed areas.

Solar energy expansion is supported by Solar Package I (Solarpaket I, 2024), which streamlines approval procedures for ground-mounted and roof-mounted systems and facilitates tenant electricity and community energy models. The broader legislative framework is complemented by the Building Energy Act (Gebäudeenergiegesetz, GEG), the Energy Efficiency Act (Energieeffizienzgesetz, EnEfG), the Combined Heat and Power Act (Kraft-Wärme-Kopplungsgesetz, KWKG), and the Fuel Emissions Trading Act (Brennstoffemissionshandelsgesetz, BEHG).

For hydrogen, the National Hydrogen Strategy (Nationale Wasserstoffstrategie) sets out a roadmap for building a hydrogen economy, including a dedicated network of over 1,800 kilometres by 2027/2028. The Hydrogen Acceleration Act (Wasserstoffbeschleunigungsgesetz, 2024) provides the legal framework to accelerate and digitalise related permitting and procurement processes. At EU level, the revised Renewable Energy Directive (RED III) and the Net Zero Industry Act (Regulation 2024/1735) are currently being transposed into German law.

Looking ahead, anticipated legislative developments include measures to accelerate grid expansion, reforms to electricity market design in line with the EU electricity market reform, and further support for green hydrogen and carbon management. The federal government that took office in May 2025 has signalled a continued commitment to renewable expansion, with a particular focus on reducing administrative burdens and streamlining planning procedures.

Germany has a wide range of government subsidy programs for renewable energies. At the federal level, private individuals and companies can obtain grants and loans for heat pumps, biomass heating systems, and solar thermal energy through the Federal Subsidy for Efficient Buildings (Bundesförderung für effiziente Gebäude, BEG), among other programs. The KfW Bank (Kreditanstalt für Wiederaufbau) offers low-interest loans and repayment subsidies for photovoltaic, wind, hydroelectric, and biomass systems in particular through loan programmes rather than direct grants. The Federal Office for Economic Affairs and Export Control (Bundesamt für Wirtschaft und Ausfuhrkontrolle, BAFA) provides subsidies specifically for solar thermal, biomass, and heat pump heating systems. There are also indirect tax incentives: private individuals, for example, benefit from energy-efficient renovation (Section 35c of the Income Tax Act [Einkommensteuergesetz, EStG]), which allows a tax reduction of 20% of the costs – up to 40,000 euros per property spread over three assessment years and available until the end of 2029. Another new approach is the German government’s climate protection agreements, which are designed to provide financial relief to companies in emission-intensive industries as they switch to climate-friendly technologies – particularly through carbon contract for difference type mechanisms. In addition, many federal states (Bundesländer) and municipalities offer additional bonuses for photovoltaics and electricity storage. For example, large cities such as Cologne subsidise the purchase of PV systems and electricity storage systems, with the exact amount depending on the power output range of the system and the applicant. Despite this wide range of support, the expansion of renewable energies in Germany remains challenging – due, among other things, to lengthy approval procedures, sluggish power grid expansion, and a complex legal framework.

The structure of the natural gas industry in Germany significantly impacts the price of electricity due to the merit-order system. In this system, electricity prices are set by the cost of the most expensive energy source used to meet demand, which is often natural gas-fired power plants. When gas prices increase, the cost of generating electricity from these plants rises, causing overall electricity prices to increase, even when renewable energy generation remains high. As gas-fired power plants are frequently used to balance supply and demand, fluctuations in gas prices directly influence electricity prices in the wholesale market. This effect has been particularly evident during recent energy crises, highlighting the strong linkage between gas and electricity prices despite the growing share of renewables with low marginal costs.

To address this issue, there are efforts underway to de-link renewable electricity prices from gas prices. One potential solution is reforming the wholesale electricity market to separate the price of renewable energy from fossil fuels. This could involve mechanisms like Contracts for Difference (CfDs), where renewable energy producers are guaranteed a fixed price for their electricity, regardless of market fluctuations. At the European level, the European Union Electricity Market Reform (adopted in 2024) aims to promote long-term contracts such as CfDs and Power Purchase Agreements (PPAs), thereby reducing the exposure of consumers to short-term gas price volatility. Germany supports these reforms and is considering the broader use of investment-based CfDs for renewable energy projects.

Other initiatives include promoting energy storage solutions and smart grids to reduce reliance on gas for balancing supply and demand of electricity, as well as increasing the use of green hydrogen, which could replace natural gas in various sectors and reduce the overall impact of gas price volatility.

Germany does not intend to permanently keep coal plants in operation beyond the legally defined phase-out timeline (2038 at the latest). However, the policy framework allows for temporary extensions or reactivations of coal-fired power plants in response to energy security concerns, as seen during the recent energy crisis. At the same time, the overall trajectory remains a gradual phase-out, with ongoing political debate about accelerating the exit to 2030.

The expansion of renewable energy in Germany faces a number of structural, regulatory, and societal challenges that are significantly slowing progress. One of the most pressing issues is the lengthy and complex approval process, especially for large-scale projects such as wind and solar farms. Bureaucratic hurdles often lead to significant delays in both planning and implementation.

In addition, existing grid infrastructure is often ill-equipped to handle the distributed nature of renewable energy production. Bottlenecks in grid expansion and delays in connecting new installations to the grid remain major obstacles, despite ongoing grid expansion and acceleration measures. At the same time, insufficient energy storage capacity limits the ability to fully utilize renewable generation, especially during periods of surplus.

Legal disputes with environmental groups or local communities also pose a significant risk to project timelines, particularly where developments are planned in environmentally sensitive or densely populated areas. Public opposition, particularly to onshore wind farms, can further complicate or even derail projects.

Smaller projects face disproportionate challenges: they are often burdened with relatively high costs and limited access to public support programs. In addition, difficulties in securing financing – due in part to the limited creditworthiness of potential counterparties – make long-term investment and project development more difficult.

Regulatory uncertainty continues to undermine investor confidence. In the absence of a clear and reliable policy framework, many companies remain cautious. Investment conditions are further constrained by national security considerations, which have led to restrictions on foreign ownership and participation in energy infrastructure. For example, Section 15(2) sentence 1 of the Offshore Wind Energy Act (Windenergie-auf-See-Gesetz, WindSeeG) allows authorities to exclude so-called “non-EU bidders” from offshore wind tenders if their participation is deemed likely to jeopardize public order or national security.

There are several key contracts involved in a new-build renewable energy project in Germany. A Power Purchase Agreement (PPA) secures the sale of electricity, specifying price and duration. An Engineering, Procurement and Construction (EPC) contract covers design, procurement, and construction. An Operations and Maintenance (O&M) contract ensures ongoing operation and maintenance after construction. Financing agreements detail the terms of project financing, including loan or bond arrangements. A grid connection agreement governs connection to the electrical grid. Land lease or purchase agreements secure land for the project. Supply contracts cover the delivery of necessary equipment. Insurance contracts cover construction and operational risks. Finally, government support agreements outline the terms of any subsidies or incentives received.

There are no specific restrictions of this kind in Germany.

German policy aims to achieve greater energy independence by expanding renewable energies. There are also no formal local content obligations or domestic supply requirements for renewable energy projects in Germany. However, regulatory developments at EU level are beginning to introduce indirect requirements related to supply chain resilience.

Under EU Regulation 2024/1735 on the “Net Zero Industry Act”, the EU will expand its production capacities for green technologies such as solar and wind power plants with the aim of covering at least 40 % of EU demand by 2030. The regulation promotes faster approval procedures and the increased development of strategic production sites, which should also benefit Germany in strengthening its competitiveness in the global market for green technologies. In addition, the regulation introduces resilience criteria for public support schemes and auctions, which may include requirements related to sustainability, cybersecurity, and diversification of supply chains. While Germany is still in the process of implementing these provisions, they are expected to influence auction design and project development going forward.

Regarding the U.S. “foreign entity of concern” (FEOC) rules under the Inflation Reduction Act, there is no direct regulatory impact on renewable energy deployment within Germany. However, these rules affect German companies active in the U.S. market – particularly in battery and clean technology supply chains – by restricting the use of components linked to certain foreign entities. More broadly, they contribute to a global trend towards supply chain localisation and risk diversification, which is increasingly shaping investment and procurement strategies in the German renewable energy sector.

The ongoing conflict in the Middle East and residual effects of the Russia-Ukraine war have reinforced the political imperative for energy security and domestic renewable generation, accelerating policy support.

However, several non-country-specific factors have created headwinds:

• elevated financing costs due to higher interest rates have increased the cost of capital for renewable projects, particularly affecting capital-intensive offshore wind developments;

• supply chain disruptions and rising raw material costs have put pressure on project economics;

• uncertainty around U.S. trade policy, including potential tariffs on renewable energy components and the possible rollback of Inflation Reduction Act incentives through the “One, Big, Beautiful Bill,” has created uncertainty for global supply chains that also serve the German market;

• changing tariff regimes and trade tensions between the EU and China, particularly regarding solar panels and battery components, have raised concerns about component availability and pricing; and

• auction results have shown signs of undersubscription in certain segments (notably offshore wind), partly reflecting these cost and risk pressures.

Despite these challenges, overall deployment has remained robust, supported by strong policy commitment and high electricity prices that improve the business case for renewables

The expansion of renewable energies in Germany is being driven forward by a series of large-scale projects.

• In the offshore sector, major wind farms such as “Nordseecluster” (RWE, 1.6 GW) and He Dreiht (EnBW, 960 MW) are making strong progress. “Nordseecluster” combines several wind farm sites in the eastern German North Sea and will supply the equivalent of around 1.6 million households. It has completed its first building phase in 2025; with turbine installation in 2026 and grid connection planned for early 2027. “He Dreiht” (85 km northwest of Borkum) has started feeding first electricity into the grid in November 2025. All wind turbines are expected to be completed by summer 2026. The project is one of Europe’s largest subsidy-free offshore projects. ..

• On land, the expansion of wind energy is focused on repowering. In Meppen (65 MW) and Börger/Breddenberg (22.2 MW), modern large-scale turbines are replacing outdated technology. They offer higher efficiency and require less space.

• In the solar sector, several gigawatt-scale projects are emerging. In Lusatia, LEAG is developing a solar complex of up to 1 GW on former lignite mining land, while projects such as the Verbund Visiolar park (2 GW) near Berlin and agro-photovoltaic plants in Brandenburg combine energy generation with agricultural use..

• In the hydrogen sector, BP is building a 100 MW electrolysis plant in Lingen to supply industry. At the same time, RWE is planning to build up to approximately 300 MW of electrolysis capacity by 2027 with GET H₂ Nukleus. In addition, an underground hydrogen storage facility (up to 70 GWh) is being built in Huntorf, which will contribute to security of supply in the future.

• In the energy storage sector, Vitol-backed company VPI is investing 450 million euros in the development of 500 MW of battery storage capacity, mostly in north-east Germany.

The European electricity infrastructure will be strengthened by the “NeuConnect” project: from 2028, a 725-kilometre underwater cable will connect Germany and the United Kingdom. With a transmission capacity of 1.4 GW, the cable will enable the exchange of surplus wind energy, thus contributing to security of supply and better integration of renewable energies at European level.

Battery energy storage systems (BESS) are rapidly gaining prominence in Germany’s renewable energy sector. Business models are evolving to capture multiple revenue streams, including frequency regulation (primary and secondary reserve), intraday and day-ahead arbitrage, redispatch services, and capacity provision. The market is seeing a growing share of standalone BESS projects, though co-located configurations (particularly solar-plus-storage) are increasingly common, driven by the ability to optimise grid connection capacity and capture higher merchant revenues. Hybrid projects combining wind or solar with BESS are emerging but remain less prevalent than in some other markets. Exact percentage breakdowns are not yet standardised in official statistics, but industry estimates suggest that standalone projects currently represent the majority of BESS capacity under development, with co-located projects growing rapidly. From a financing perspective, the bankability of BESS projects has improved significantly as revenue stacking models become more established and as lenders gain familiarity with the technology. However, merchant revenue risk remains a key challenge, and many project finance structures require a combination of contracted revenues (e.g., tolling agreements or capacity contracts) and merchant exposure, with conservative debt sizing assumptions.

To facilitate confidence in new development and financing in newer areas like offshore wind and hydrogen in Germany, several factors are required:

• regulatory certainty and long-term policy visibility, including clear auction pipelines, stable support mechanisms, and predictable permitting timelines;

• for offshore wind, the continued pre-investigation of sites by the Federal Maritime and Hydrographic Agency (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and the timely expansion of grid connection infrastructure by the TSOs in Germany are critical — delays in grid connection have historically been a significant risk factor;

• for hydrogen, the establishment of a functioning regulatory framework (including the classification of hydrogen as an energy carrier under the EnWG, the finalisation of the hydrogen backbone network, and clarity on green hydrogen certification under the EU Delegated Acts) is essential;

• bankable offtake structures, such as long-term hydrogen purchase agreements (HPAs) or government-backed contracts for difference (H2 CfDs), are needed to bridge the current cost gap between green hydrogen and conventional alternatives;

• the availability of public co-financing and guarantees (e.g., through KfW, the European Hydrogen Bank, or IPCEI funding) to de-risk early-stage projects; and

• the development of a liquid secondary market for project equity and debt to attract institutional investors.

Renewable energy projects in Germany are typically financed through a mix of equity, loan, and government support. Project finance is often used where funds are raised based on the future cash flows of the project, often on a non‑recourse or limited‑recourse basis. Bank loans and green bonds are also common. Private equity and infrastructure funds often invest in both the development and operating phases of large-scale renewable energy projects.

The Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG) is a central pillar of the investment landscapeIt does not provide fixed revenue guarantees, but supports projects mainly through competitive auctions combined with a sliding market premium, which stabilises revenues and enhances bankability. As a result, EEG‑supported projects continue to attract long‑term financing from commercial banks and development finance institutions..

For projects that are not (or no longer) covered by the Renewable Energy Act, corporate power purchase agreements (PPAs) are gaining in importance.

These long term offtake agreements provide revenue certainty and enable market based financing, particularly for solar PV and onshore wind projects.

To make these projects a reality, the government needs to use de-risking instruments. The KfW Bank (Kreditanstalt für Wiederaufbau) is providing low-interest loans of up to 150 million euros. The Federal Office of Economics and Export Control (Bundesamt für Wirtschaft und Ausfuhrkontrolle, BAFA) is providing targeted support, in partiuclar to small and medium-sized enterprises in their transition to renewable energies. BAFA has numerous funding programs on behalf of the Federal Ministry of Economics and Energy (Bundesminsterium für Wirtschaft und Energie, BMWE).

The rising demand for data centres is having an increasingly significant impact on the German electricity grid and prices. Germany is one of Europe’s largest data centre markets, with Frankfurt being a major hub. Data centre electricity consumption is projected to grow substantially, driven by the expansion of cloud computing, artificial intelligence, and digitalisation. This growing demand places additional strain on the electricity grid, particularly in urban areas where grid capacity is already constrained. It also contributes to upward pressure on electricity prices, as additional baseload demand tightens the supply-demand balance. In response, data centre operators are increasingly entering into long-term corporate PPAs with renewable energy generators to secure green electricity supply and price certainty. Some operators are also investing directly in renewable energy assets or co-locating data centres with renewable generation and storage facilities. In 2023, the German government has introduced energy efficiency requirements for data centres through the Energy Efficiency Act (Energieeffizienzgesetz, EnEfG), which mandates minimum efficiency standards (power usage effectiveness [PUE] values) and requires the utilisation of waste heat. Grid operators and policymakers are also examining how data centre demand can be managed flexibly to support grid stability, for example through demand response mechanisms.
