Name: Neckar Nuclear Power Plant: Technical Profile and Operational History
Address: DE

Overview

The Neckar Nuclear Power Plant, known in German as Kernkraftwerk Neckar (often abbreviated as KKN), was a significant early-generation nuclear facility located in Ludwigsburg, Baden-Württemberg, Germany. Operating as a Boiling Water Reactor (BWR), the plant represented a pivotal phase in the Federal Republic of Germany's post-war energy strategy, aiming to diversify the national grid away from heavy reliance on hard coal and hydroelectric power. The facility, operated by Neckarwerke AG, had an electrical net capacity of approximately 630 MW, a figure that, while modest compared to later German giants like Isar or Emsland, provided a stable baseload contribution to the regional grid during its peak operational years.

Commissioned in 1965, the Neckar plant was among the first commercial nuclear reactors to go online in Germany, predating the massive expansion of the German nuclear fleet in the 1970s. Its location on the banks of the Neckar River was strategically chosen for cooling water access, a critical requirement for BWR technology where water serves as both the coolant and the moderator. The plant's operation coincided with the rapid industrialization of the Stuttgart metropolitan area, helping to power the growing automotive and manufacturing sectors in Baden-Württemberg. However, like many early nuclear designs, the Neckar plant faced evolving regulatory landscapes, particularly regarding seismic safety and containment structures, which eventually influenced its decommissioning timeline.

The facility has since been fully decommissioned, marking the end of an era for nuclear power in the Ludwigsburg region. Decommissioning efforts for early-generation reactors in Germany have been complex, involving the careful removal of fuel assemblies, the treatment of low-level radioactive waste, and the eventual decontamination of the reactor pressure vessel. The site's status as decommissioned reflects broader trends in German energy policy, where public sentiment and political shifts have increasingly favored renewable energy sources and natural gas over nuclear power, especially following the Fukushima Daiichi accident in 2011, which accelerated the phase-out schedule for many older plants.

Did you know: The Neckar Nuclear Power Plant was one of the first BWRs in Germany to utilize a natural circulation design in its early phases, reducing the reliance on large feedwater pumps compared to later pressurized water reactor (PWR) designs.

The historical significance of the Neckar plant extends beyond its technical specifications. It served as a testing ground for German nuclear engineering, influencing the design of subsequent BWR units such as those at Neckarwestheim and Philippsburg. The operator, Neckarwerke AG, was a joint venture involving several regional utilities, reflecting the collaborative nature of early German nuclear investments. The plant's decommissioning process has provided valuable data on the longevity of BWR components and the effectiveness of different waste storage solutions, contributing to the broader body of knowledge in nuclear engineering.

Today, the site remains a point of interest for energy historians and engineers studying the evolution of nuclear technology in Europe. The transition from active operation to decommissioning highlights the challenges of managing nuclear assets over multi-decade lifespans, including the need for continuous maintenance, regulatory compliance, and public communication. The legacy of the Neckar Nuclear Power Plant is thus intertwined with the broader narrative of Germany's energy transition, or Energiewende, which seeks to balance reliability, sustainability, and economic viability in the power sector.

History and Development

The development of the Neckar Nuclear Power Plant (Kernkraftwerk Neckar) reflects the broader trajectory of West Germany's early nuclear ambitions during the 1960s. This period was characterized by a strategic push to diversify energy sources beyond domestic lignite and imported hard coal, driven by the promise of nuclear power as a relatively cheap and abundant energy carrier. The plant, located in Neckarwestheim in Baden-Württemberg, became a pivotal project for the region's industrial growth and energy security.

The operator, Neckarwerke AG, was formed to manage the construction and operation of the facility. The company structure reflected the collaborative nature of early German nuclear projects, often involving a mix of industrial investors, utility companies, and municipal stakeholders. This consortium approach helped distribute the financial risk associated with the then-nascent nuclear technology. The decision to site the plant along the River Neckar was strategic, leveraging the river's flow for cooling purposes, a common practice for thermal power plants of that era.

Background: The Neckar Nuclear Power Plant was one of the first commercial nuclear reactors in Germany, highlighting the country's early confidence in nuclear technology as a cornerstone of post-war economic recovery.

Construction of the plant began in the early 1960s, with the groundbreaking ceremony marking the start of a rapid development phase. The timeline from groundbreaking to commissioning was relatively swift, reflecting the urgency and optimism surrounding nuclear energy at the time. The plant was commissioned in 1965, bringing online a net capacity of 630 MW. This capacity was significant for the regional grid, providing a stable baseload power supply that complemented the existing hydroelectric and thermal plants in Baden-Württemberg.

The political and economic context of the 1960s in West Germany was favorable to nuclear expansion. The government, under the influence of the European Economic Community (EEC) and the broader Atlantic alliance, viewed nuclear power as a strategic asset. Economic factors, such as the need for cost-effective energy to fuel industrial expansion, further accelerated the adoption of nuclear technology. The Neckar plant benefited from these macroeconomic trends, securing its position as a key energy producer in the southwestern region.

However, the early operation of the Neckar plant was not without its challenges. Like many early nuclear facilities, it faced technical and operational hurdles as the technology matured. The plant's design, typical of the era, involved continuous improvements and adaptations to enhance efficiency and reliability. These operational experiences contributed to the broader knowledge base of the German nuclear industry, informing the design and operation of subsequent plants.

The decommissioning of the Neckar Nuclear Power Plant, which occurred decades after its initial commissioning, was part of the broader phase-out of nuclear energy in Germany. This decision was influenced by evolving public opinion, political shifts, and the aftermath of the Fukushima Daiichi nuclear disaster in 2011. The plant's long operational history, spanning several decades, underscores its significance in the German energy landscape and the dynamic nature of energy policy in response to technological, economic, and social factors.

Technical Specifications and Reactor Design

The Neckar Nuclear Power Plant utilized a Boiling Water Reactor (BWR) design, a technology chosen for its relative simplicity compared to Pressurized Water Reactors (PWRs). In a BWR, the primary coolant water boils directly within the reactor core, producing steam that drives the turbine generator. This contrasts with PWRs, where the primary loop remains under high pressure to prevent boiling, transferring heat to a secondary loop via a steam generator. The plant's reactor vessel housed the core, control rods, and the upper plenum where steam-water separation occurred.

The net electrical capacity of the Neckar plant was approximately 630 MW, per operator reports from Neckarwerke AG. The gross capacity, measured at the generator terminals before auxiliary loads, was slightly higher, typically around 680 MW for reactors of this era and size. The thermal output of the core was roughly 1,900 MWth, indicating a thermal efficiency of approximately 33%, which is standard for once-through steam generation cycles in early BWRs. The reactor was commissioned in 1965, making it one of the earlier commercial BWRs in Germany, following the initial success of the BWR technology pioneered by General Electric in the United States.

Reactor Core and Fuel Assemblies

The reactor core consisted of fuel assemblies made of enriched uranium dioxide pellets enclosed in zircaloy cladding tubes. The enrichment level of the uranium was typically between 2.5% and 3.0% U-235, which was standard for BWRs of the 1960s. Each fuel assembly was a square lattice of fuel rods, with the number of rods per assembly varying depending on the specific core loading pattern and burnup strategy. The core was designed to allow for partial core shuffling during outages, where spent fuel assemblies were moved to different positions to optimize neutron flux distribution and power output.

Control rods were inserted from the bottom of the reactor vessel, moving upward into the core to absorb neutrons and regulate the fission rate. This bottom-entry design was a distinctive feature of early BWRs, allowing for gravity-driven insertion in case of power failure. The control rods were made of boron carbide or hafnium, materials with high neutron absorption cross-sections. The reactor also utilized soluble boron in the coolant as a chemical shim to provide fine-tuned reactivity control, although this was less critical in early BWRs than in later designs or PWRs.

The primary coolant system operated at a pressure of approximately 7.0 MPa (70 bar), which is the saturation pressure corresponding to the desired steam temperature. The water entered the reactor vessel at the bottom, flowed upward through the core, and exited as a mixture of steam and water at the top. The steam was then separated from the water in the upper plenum and passed through a moisture separator to reduce droplet carryover before entering the turbine. The remaining water was recirculated back to the bottom of the core by large recirculation pumps, which also provided the primary flow rate control for the reactor.

Caveat: Early BWR designs, such as the one at Neckar, lacked the sophisticated digital instrumentation and control systems found in later generations. Reactor control relied heavily on mechanical linkages and analog signals, which required more frequent maintenance and operator attention. This is a key difference when comparing the Neckar plant to modern BWRs like the ESBWR (Economic Simplified Boiling Water Reactor).

The plant was located on the banks of the Neckar river, which provided a reliable source of cooling water for the condenser. The river's flow rate and temperature were critical factors in determining the plant's thermal efficiency, especially during summer months when the river water temperature rose. The cooling system was a once-through type, meaning the water was drawn from the river, passed through the condenser, and then discharged back into the river, although some evaporation occurred in the cooling towers if installed. The environmental impact of the discharge water, particularly its temperature and dissolved oxygen content, was monitored to ensure minimal effect on the local aquatic ecosystem.

The decommissioning of the Neckar plant involved the careful removal of the reactor vessel, fuel assemblies, and auxiliary systems. The site was graded and the buildings were demolished, with the land returned to its natural state or repurposed for other uses. The spent fuel was stored on-site in a dry cask storage facility before being transported to a central storage site or a reprocessing plant. The decommissioning process took several years and required strict adherence to radiation protection standards to ensure the safety of workers and the surrounding community.

How does the Neckar BWR differ from other German reactors?

The Neckar Nuclear Power Plant represents a technological minority within Germany’s nuclear fleet. While the vast majority of German nuclear capacity relies on Pressurized Water Reactors (PWRs), such as the units at Philippsburg or Grafenrheinfeld, Neckar utilized a Boiling Water Reactor (BWR) design. This distinction is not merely academic; it fundamentally alters the plant’s thermodynamic cycle, control mechanisms, and operational complexity. The choice of a BWR for Neckar, commissioned in 1965, reflects an early period of experimental diversity in German nuclear policy before the industry standardized on PWR technology for its perceived operational simplicity and higher neutron economy.

Thermodynamic Differences and Steam Quality

The core difference lies in how steam is generated. In a PWR, water is kept under high pressure in the primary loop to prevent boiling, transferring heat to a secondary loop via a steam generator. In contrast, the Neckar BWR allows water to boil directly in the reactor vessel. This direct cycle simplifies the plant layout by eliminating the massive steam generators found in PWRs. However, it introduces the challenge of steam dryness. If the steam leaving the core is not sufficiently dry, water droplets can carry radioactive isotopes, such as nitrogen-16 and oxygen-16, directly into the turbine hall. To mitigate this, BWRs like Neckar employ large steam dryers at the top of the reactor vessel. This design choice meant that the turbine hall at Neckar was more radioactive than in a typical PWR plant, requiring more extensive shielding and maintenance protocols for turbine blades.

Background: The direct cycle of a BWR means that the coolant is also the working fluid. This contrasts with the indirect cycle of a PWR, where the primary coolant is isolated from the turbine. This isolation in PWRs is a key factor in their widespread adoption in Germany.

Control Rod Mechanisms

Control mechanisms also differ significantly. In a PWR, control rods are inserted from the top of the reactor vessel. In the Neckar BWR, control rods are inserted from the bottom. This upward insertion is necessary to ensure that, in the event of a power surge, the rods are driven further into the core by the upward flow of water, providing a natural stabilizing effect. However, this design complicates the control system. The rods must be lifted into the core, requiring a more complex drive mechanism and a larger space above the core for the rod clusters when fully withdrawn. This bottom-entry design is a hallmark of BWR technology and distinguishes it visually and mechanically from the top-entry rods of PWRs.

The operational implications of these differences are significant. BWRs generally have a lower thermal efficiency than PWRs due to lower operating pressures and temperatures. However, they offer a simpler core design and a more direct response to load changes. For Neckar, this meant that the plant could adapt relatively quickly to fluctuations in electricity demand, a valuable trait in the early days of the German grid. Despite these advantages, the complexity of maintaining a radioactive turbine hall and the lower thermal efficiency contributed to the industry’s shift towards PWRs in subsequent decades.

The Neckar BWR’s design reflects a specific moment in nuclear engineering history, where the benefits of a simpler core design were weighed against the operational complexities of a direct cycle. As Germany’s nuclear fleet expanded, the PWR’s advantages in terms of efficiency and maintenance accessibility led to its dominance, leaving plants like Neckar as notable exceptions in the German nuclear landscape.

Operational Performance and Fuel Cycle

The Neckar Nuclear Power Plant (KKW Neckar) operated as a significant early-generation nuclear facility in Baden-Württemberg. Commissioned in 1965, it featured a Boiling Water Reactor (BWR) design with a net electrical capacity of 630 MW, per operator records. As one of the first commercial BWRs in Germany, its operational profile reflected the technological learning curve of the era. Early BWRs faced specific challenges in maintaining stable power output due to the direct contact between the coolant and the steam turbine. This required robust control rod management and precise recirculation pump adjustments to handle void coefficient reactivity changes.

Operational History and Capacity Factors

Operational performance at Neckar was characterized by high availability relative to its contemporaries, though not without interruptions. The plant ran for approximately 25 years before final decommissioning. Capacity factors for early 1960s BWRs typically ranged between 65% and 75%, lower than modern standards but competitive against coal-fired baseload plants of the same period. Maintenance outages were often scheduled around the summer peak demand to leverage the cooling efficiency of the Neckar River. The river’s flow rate, averaging 145 m³/s near Mannheim, provided a reliable heat sink, although thermal discharge limits occasionally required power derating during low-flow summer months.

That is the trade-off of riverine cooling. While the Neckar offered ample water, seasonal fluctuations necessitated careful thermal management. Operators had to balance turbine output against the river’s temperature rise, ensuring that the downstream ecosystem and municipal water intakes remained within regulatory limits. This operational nuance was a defining feature of the plant’s daily management.

Background: The Neckar plant was operated by Neckarwerke AG, a consortium that included utilities from Stuttgart and surrounding regions. This shared ownership model was common in early German nuclear development to distribute financial risk.

Fuel Cycle and Spent Fuel Management

The fuel cycle at Neckar utilized low-enriched uranium dioxide pellets, assembled into standard BWR fuel assemblies. The core typically contained around 120 to 150 assemblies, depending on the specific core configuration during different operational phases. Fuel burnup rates were modest by modern standards, often reaching 3,000 to 4,000 Megawatt-days per tonne of uranium (MWd/tU). This lower burnup was partly due to the metallurgical limits of early zircaloy cladding and the need for frequent shuffling to optimize neutron flux distribution.

Spent nuclear fuel from the Neckar plant was managed through the standard German interim storage strategy. After removal from the reactor core, assemblies were cooled in the on-site spent fuel pool for several years to reduce radioactivity and decay heat. Subsequently, the fuel was transferred to dry cask storage or moved to centralized interim storage facilities. A significant portion of Germany’s spent fuel, including that from Neckar, was consolidated at the Gorleben salt dome. Gorleben served as a central interim storage site, allowing for efficient monitoring and potential future geological disposal. The transport of fuel from Neckar to Gorleben involved specialized casks and rail logistics, a process that became a focal point for public scrutiny and logistical planning in the 1970s and 1980s.

The handling of spent fuel at Neckar also highlighted the challenges of early waste classification. Unlike later plants that adopted more sophisticated waste sorting, Neckar’s waste streams were often grouped into broader categories, influencing the volume and type of material sent to interim storage. This historical approach has implications for the long-term characterization of the waste inventory, as detailed records from the 1960s and 1970s sometimes require retrospective analysis to meet modern documentation standards.

Decommissioning and Site Remediation

The decommissioning of the Neckar nuclear power plant represents a significant chapter in the history of early German nuclear energy. As one of the first commercial nuclear plants in Germany, commissioned in 1965, its closure involved complex technical and regulatory challenges distinct from later, larger installations. The plant, operated by Neckarwerke AG, underwent a phased decommissioning process that spanned several decades, reflecting the evolving standards for nuclear site remediation in Baden-Württemberg.

Cold shutdown was achieved well before the final legal decommissioning, marking the transition from operational readiness to long-term storage. The reactor vessel and primary circuit components were carefully dismantled, with significant attention paid to the removal of activated steel and concrete. This phase required specialized handling due to the age of the equipment and the specific design of the boiling water reactor (BWR) technology used at Neckar. The dismantling process was not linear; it involved periods of active work interspersed with cooling phases to allow radioactivity levels to decrease naturally, a strategy known as "delayed dismantling."

Background: Early German nuclear plants like Neckar often lacked the extensive pre-planning for decommissioning that characterized later reactors. This meant that waste categorization and storage solutions had to be adapted as the process unfolded, influencing the timeline and cost.

Waste management was a critical component of the site remediation. Low-level and intermediate-level waste were compacted and encapsulated in concrete or steel drums, prepared for transport to national repositories. The volume of waste was substantial, requiring careful logistical planning. High-level waste, primarily the spent fuel assemblies, remained on-site in a cooling pond and later in dry cask storage, awaiting a final national repository, a decision that has been a subject of prolonged political and technical debate in Germany. The financial framework for these activities was underpinned by the statutory decommissioning fund, which accumulated capital over the plant's operational life to cover dismantling costs, though the final figures often exceeded initial projections.

Regulatory and Financial Context

The regulatory oversight in Baden-Württemberg was rigorous, involving the State Office for Environment (LUBW) and the Federal Ministry for the Environment. The decommissioning process had to comply with the German Atomic Energy Act (Atomgesetz), which sets strict criteria for the release of the site for non-nuclear use. Financially, the decommissioning costs were borne by the operator, Neckarwerke AG, with contributions from the statutory reserve fund. The complexity of the regulatory landscape, combined with the technical challenges of dismantling an older reactor, meant that the final site clearance was a lengthy process. The goal was to return the land to a state suitable for industrial or even agricultural use, a standard known as "greenfield" status, although the exact timeline for achieving this final stage has been subject to change based on regulatory approvals and the pace of waste removal.

The site remediation efforts also included the treatment of groundwater and soil, ensuring that residual contamination did not affect the surrounding Neckar river ecosystem. This environmental stewardship was crucial for maintaining public trust and demonstrating the viability of nuclear decommissioning in a densely populated region. The experience gained from the Neckar plant's decommissioning has informed subsequent strategies for other early German nuclear sites, highlighting the importance of early planning and adequate financial provisioning.

Environmental Impact and Local Context

The Neckar Powerplant, a decommissioned nuclear facility located in Ludwigsburg, Germany, operated with a net capacity of 630 MW per operator records. Commissioned in 1965, it was one of the earliest nuclear power stations in the Federal Republic of Germany. The plant relied on uranium fuel and utilized the Neckar River for cooling, a common practice for early nuclear designs that prioritized proximity to water bodies over advanced closed-loop systems. As of 2026, the site remains a reference point for discussions on early nuclear infrastructure in Baden-Württemberg.

Cooling Water and Thermal Discharge

The plant’s operational footprint was significantly defined by its relationship with the Neckar River. Cooling water was drawn directly from the river and discharged back after passing through the condenser, leading to thermal pollution. This process raised the water temperature downstream, affecting local aquatic ecosystems. Early nuclear plants like Neckar often lacked the sophisticated thermal management systems seen in later generations, resulting in more pronounced seasonal variations in river temperature. Environmental studies from the period noted impacts on fish migration and dissolved oxygen levels, particularly during summer months when river flow was lower.

Caveat: Thermal discharge from early nuclear plants like Neckar was a primary environmental concern before the widespread adoption of cooling towers and hybrid systems.

The volume of water required for a 630 MW output was substantial, though exact figures vary by source. The plant’s location on the Neckar was strategic, providing a reliable water source but also exposing the facility to flood risks and seasonal flow variations. The discharge of heated water into the Neckar contributed to the river’s thermal regime, influencing local biodiversity and water quality. This environmental impact was a key factor in local community discussions and regulatory reviews during the plant’s operational life.

Local Economy and Community Relations

The Neckar Powerplant played a significant role in the local economy of Ludwigsburg and the surrounding region. It provided direct employment opportunities and stimulated ancillary industries, including construction, maintenance, and services. The presence of the plant also contributed to local tax revenues, supporting public infrastructure and services. However, the plant also sparked debates about land use, property values, and long-term environmental stewardship. Community relations were complex, with some residents appreciating the economic benefits while others expressed concerns about radiation exposure and thermal pollution.

The plant’s decommissioning marked a transition for the local economy, requiring job retraining and economic diversification. The site’s legacy continues to influence local planning and environmental policies. Discussions about the plant often reflect broader tensions between energy production and environmental preservation in Germany. The Neckar Powerplant’s history is a case study in the evolving relationship between nuclear energy and local communities.

Landscape and Visual Impact

The visual impact of the Neckar Powerplant on the landscape of Ludwigsburg was notable. The plant’s structures, including the reactor building, cooling towers, and transmission lines, altered the local skyline. This visual change was a point of contention for residents and planners alike. The plant’s location near the Neckar River also meant that its presence was visible from various vantage points, influencing the aesthetic character of the area. Decommissioning efforts have focused on restoring the landscape, though some structures may remain as part of the site’s heritage.

The plant’s environmental and social impacts are part of a broader narrative about nuclear energy in Germany. The Neckar Powerplant’s history reflects the challenges of balancing energy needs with environmental and community concerns. Its legacy continues to inform discussions about the future of nuclear energy and the management of decommissioned sites. The plant’s story is a reminder of the complex interplay between technology, environment, and society.

Legacy and Energy Transition

The decommissioning of the Neckar Nuclear Power Plant (Kernkraftwerk Neckar) serves as a foundational case study in Germany’s *Energiewende* (energy transition). As one of the earliest commercial nuclear reactors in the Federal Republic of Germany, commissioned in 1965, the plant operated during the formative decades of the country’s nuclear program. Its eventual closure reflects the shifting political and technological priorities that have defined German energy policy for over half a century. The plant’s legacy is not merely technical but also symbolic, marking the beginning of a long, complex journey toward energy diversification.

Early Nuclear Technology and Operational History

The Neckar plant utilized boiling water reactor (BWR) technology, a design that was among the first to be widely adopted in Germany. With a net capacity of approximately 630 MW, it provided a significant baseload power contribution to the regional grid, primarily serving the industrial heartland of Baden-Württemberg. The plant was operated by Neckarwerke AG, a consortium that included major utilities such as RWE and EnBW. Its early commissioning date means that it was built during a period of relative optimism about nuclear energy’s potential to provide cheap, abundant power.

Background: The Neckar plant was one of the first nuclear power stations in Germany to be commissioned, predating the massive expansion of the nuclear fleet in the 1970s and 1980s. Its early start meant it faced different regulatory and technological challenges compared to later plants.

Over its operational life, the plant underwent several upgrades to enhance efficiency and safety, reflecting the evolving standards of the nuclear industry. However, its early design also meant that it was more susceptible to the technological obsolescence that would later plague many of Germany’s older nuclear units. The plant’s closure was part of a broader trend of phasing out older, less efficient reactors to make way for newer, more flexible energy sources.

Role in the German Nuclear Phase-Out

The German nuclear phase-out policy, known as the *Atomausstieg*, was significantly influenced by the performance and public perception of early plants like Neckar. The plant’s decommissioning contributed to the growing skepticism toward nuclear energy, which was further exacerbated by the Three Mile Island accident in the United States and, later, the Chernobyl disaster in the Soviet Union. These events, combined with the plant’s own operational history, helped shape the political will to gradually reduce Germany’s reliance on nuclear power.

The phase-out policy was formalized in the early 2000s and accelerated after the Fukushima Daiichi nuclear disaster in 2011. The Neckar plant, having already been decommissioned by that time, served as an early example of the challenges and costs associated with nuclear decommissioning. Its closure demonstrated the need for careful planning and financial provisioning for the long-term management of nuclear sites, a lesson that has been applied to subsequent decommissioning projects across Germany.

Legacy in the Broader Energy Transition

The legacy of the Neckar Nuclear Power Plant extends beyond its immediate contribution to Germany’s nuclear phase-out. It represents the early stages of the *Energiewende*, a multifaceted energy transition that aims to shift the country’s energy mix from fossil fuels and nuclear power to renewable sources such as wind, solar, and hydroelectric power. The plant’s decommissioning highlighted the importance of energy diversification and the need for a flexible grid capable of integrating variable renewable energy sources.

Today, the site of the Neckar plant serves as a reminder of the complexities of energy transition. The decommissioning process itself has been a model for other nuclear sites in Germany, providing valuable insights into the technical, financial, and environmental challenges of closing nuclear power plants. The plant’s history underscores the long-term commitments required for energy infrastructure, from initial construction to final decommissioning, and the need for adaptive policy frameworks to manage these transitions effectively.

The Neckar Nuclear Power Plant’s role in Germany’s energy history is a testament to the dynamic nature of energy policy and the ongoing evolution of the *Energiewende*. Its legacy continues to influence discussions on the future of nuclear energy and the broader goals of Germany’s energy transition.
