Renewable energy – translation as leverage for project financing

Projects are becoming more international, partners more diverse, and legal frameworks more complex. The energy transition transcends national borders and languages alike. To break down the associated language barriers, accurate translations are a key factor for the success of your projects. This is especially true when it comes to financing, approvals, and communication.

As projects become more geographically dispersed, documentation requirements are becoming increasingly rigorous. Energy projects rely heavily on contracts, expert reports, presentations, and technical documentation—and their financing even more so.

Banks, investors, and public funding agencies in the energy sector obviously expect documents written in their respective language. While grammatical accuracy is essential here, the paramount requirement is precise content representation. A mistranslated technical term in a power purchase agreement can delay due diligence. An unclear expert report can block approval procedures. An ineptly worded investor presentation can undermine the confidence of potential financiers.

The following examples illustrate where linguistic precision is particularly critical in the energy sector and how you can avoid common pitfalls.

PPAs – different countries, different laws

Power Purchase Agreements (PPAs) form the backbone of many renewable energy projects. They regulate the long-term offtake of electricity and are therefore crucial to a project’s economic viability. PPAs are established contractual instruments in Germany and the U.S., but the legal and linguistic requirements vary significantly from country to country.

Example: PPAs in Germany and Spain

In Germany, a PPA is often referred to as a “Stromliefervertrag” (literally: electricity supply contract) or “Stromabnahmevertrag” (literally: electricity purchase agreement), but the literal translation alone is not sufficient. Spanish PPAs, for example, contain specific clauses on “force majeure” (act of God), which are interpreted differently under German law. A literal translation of “force majeure” as “fuerza mayor” is linguistically correct but insufficient. Under Spanish law, the term also encompasses events such as strikes or political unrest, which are not automatically included in Germany.

Here is another example: The “Change in Law” clause is often literally translated as “Gesetzesänderung” in German contracts. However, in Spain, this clause may also cover regulatory changes at the regional level, which in Germany would be regulated at the federal level. Without knowing this subtle distinction, the translation may be legally indefensible.

Practical tip: If you are working on international PPAs, you should collaborate with native-speaking translators who are not only proficient in the target language but also understand the legal frameworks of the respective countries. Ideally, they should have experience with energy contracts, since a PPA is much more than a simple supply agreement.

EIA for multinational permitting processes

An environmental impact assessment (EIA) is a prerequisite for approval of energy projects in many countries. Unfortunately, while the process is harmonized by directives within the EU, there are country-specific differences—not only in terms of content but also in language and form.

Example: EIA in Germany and France

In Germany, the EIA is a formalized procedure with clear guidelines under the Environmental Impact Assessment Act (Umweltverträglichkeitsprüfungsgesetz; UVPG). In France, where it is referred to as “Étude d’Impact Environnemental,” the focus is more on public participation (“enquête publique”). While the term “Artenschutz” (species protection) is clearly defined in Germany, the French equivalent “protection de la biodiversité” can be broader in scope and encompass additional aspects such as landscape conservation or habitat connectivity.

The structure of the reports also differs in that German EIA reports often follow a strictly structured format, while French studies leave more room for narrative elements. A literal translation would ignore these differences and could result in the authorities requesting revisions.

Practical tip: Work with specialized translators with expertise in environmental law and experience working with government agencies. This ensures that your documents meet all substantive and stylistic requirements.

Translation of investor presentations for energy funds

Convincing investors is one of the biggest challenges when it comes to financing renewable energy projects. But while a presentation in Germany is often factual and data-driven, different expectations may apply in other countries.

Example: Investor presentations in the U.S. and Japan

In the U.S., investors value clear facts, risk analyses, and ROI projections. The presentation is often data-driven and to the point. Long introductions or detailed background explanations are seen as a waste of time. In Japan, on the other hand, the relationship aspect plays a much greater role. Presentations are more formal with greater emphasis on introducing the team, the company’s history, and the long-term vision. Direct criticism or overly aggressive sales rhetoric can be perceived as rude.

Practical tip: A literal translation of your German investor presentation may be perceived as impersonal or even disrespectful in Japan. Conversely, a Japanese presentation in the U.S. may come across as too vague or lacking focus. Therefore, you should not only adapt the language to the expectations of your target audience but also the structure and tone of your presentation. Work with native-speaking translators who are familiar with cultural norms. A successful presentation is more than the sum of its words.

Terminology pitfalls: How do translators handle terms like “grid,” “feed-in tariff,” or “curtailment”?

Many technical terms cannot simply be translated word-for-word. Literal translations in this area often cause confusion with potentially far-reaching consequences. Three examples.

1. “Grid” – not always simply “Netz”

The English term “grid” is often translated as “Netz.” However, while “grid” in the Anglo-Saxon world encompasses the entire power grid, including infrastructure, closed-loop control technology, and market mechanisms, “Netz” in German often refers only to the physical infrastructure. In a contract, this distinction can be crucial, since “grid connection” not only refers to the physical connection but also encompasses integration into the electricity market.

2. “Feed-in Tariff” – more than just “feed-in remuneration”

The “feed-in tariff” is a key concept in Germany’s energy transition, as defined by the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz; EEG). However, while the English term “feed-in tariff” is often used synonymously, there are state-specific differences. In some states, the term refers only to government-set tariffs, while in others it also includes market-based models or premiums.

3. “Curtailment” – one term, many meanings

In the energy sector, “curtailment” refers to the targeted reduction of electricity feed-in, for example when the grid is overloaded or during periods of negative price volatility. In German, the correct equivalent depends on the context, resulting in more appropriately nuanced terms like “Netzengpassmanagement” (grid congestion management), “Einspeisemanagement” (feed-in management), or “Drosselung” (throttling).

Case study from the renewable energy sector: an offshore wind farm project with partners from 7 countries

International projects in the renewable energy sector are extremely complex, regardless of whether they focus on solar energy, hydropower, photovoltaics, or geothermal energy. This is illustrated by the example of an offshore wind farm in the North Sea. Imagine the following scenario: Partners from Germany, Denmark, the Netherlands, Belgium, France, Norway, and the United Kingdom are involved in the project.

The starting point

The consortium consists of:

• Project developers from Germany and Denmark
• Technology partners from the Netherlands and Norway
• Investors from Belgium and France
• Grid operators from the United Kingdom

The documentation includes:

• Technical specifications (English, German, Danish)
• Financing agreements and PPAs (English, French, Dutch)
• Environmental reports (German, Dutch, French)
• Permit documents (each in the local language of the relevant authority)

The Challenges

1. Terminology: Even seemingly simple terms like “wind turbine” are interpreted differently: In Germany, “Windkraftanlage” usually refers to the entire plant, including the foundation and grid connection, while in Denmark, the term “vindmølle” can also refer solely to the turbine. Standardized terminology is essential to avoid ambiguity.

2. Legal differences: Contracts must not only be translated but also adapted to the respective legal systems. For example, in British common law, there is no direct equivalent to the German “Planfeststellungsbeschluss” (planning approval decision). An explanatory rendering is necessary here for clarity.

3. Cultural Differences: While German partners value detailed risk analyses and technical precision, French investors place greater emphasis on narrative elements, such as presenting the long-term vision and the strategic significance of the project.

The Solution

A translation agency is brought into the project at an early stage to handle the following tasks:

• Terminology management: A multilingual glossary is mandatory for all project participants. This ensures that terms such as “curtailment,” “feed-in tariff,” or “grid connection” are used consistently.
• Legal adaptation: The contracts are not only translated but also reviewed and annotated by lawyers with experience in energy and international law.
• Cultural adaptation: Presentations and reports are not translated word-for-word but adapted to the expectations of the respective target audience, for example, by emphasizing facts and figures for German stakeholders and highlighting the strategic perspective for French investors.

The Result

Thanks to the early involvement of professional translators and consistent terminology management, misunderstandings are avoided and delays are minimized. The project receives the necessary approvals in all participating countries and can be financed on schedule. The collaboration between partners from seven countries proceeds smoothly, primarily because everyone involved has access to consistent, precise documentation.

Our recommendations for your next project
