Energy supply and infrastructure

multidisciplinary consulting.

The multidisciplinary energy and infrastructure team at SONNTAG has been supporting private and public clients in the successful implementation of energy and infrastructure projects for twenty years. Renewable energies, district heating supply and water management are our focal points.

According to the motto "law and calculation", we support all project phases in a business management and legal context. From the initial idea, through preparation and implementation, right up to ongoing operation.

Together with you, we discuss the conception of the projects from an economic and legal point of view. We accompany you through subsidy procedures and project financing, develop and negotiate the necessary contracts and provide support in approval procedures. Many years of experience in bidding and EU-wide award procedures round off our profile.

To ensure the success of the project, we act in an economically and legally holistic manner. We combine in-depth knowledge of the industry with sustainable interfaces with engineers, technicians and geologists resulting from many years of cooperation. Whenever it becomes necessary in the course of a project, we also conduct court proceedings, such as antitrust disputes over supply prices.

We promote climate protection out of conviction and actively shape the energy and heat turnaround for Germany together with our clients. Together we identify potential for the use and expansion of renewable energies. We are leaders in advising on the use of deep geothermal energy for heat supply and power generation. The geothermal expertise of the SONNTAG team stems from a large number of successfully implemented and advised projects in this specialised sector.

Since 2004, the team has implemented projects with a thermal capacity of around 200 MW and an investment volume of more than 500 million Euros in its central function as business and legal advisor. SONNTAG's energy and infrastructure team therefore has a broad advisory spectrum.

  • At the interfaces to technology and law, we examine the economic viability, create acceptance and help with implementation.
  • For geothermal projects, we create complex economic simulations and a wide range of scenario analyses. These serve as the basis for decision-making in committees, negotiations with banks and applications for subsidies to finance the projects.

  • In Germany, we have already helped to implement nine major geothermal projects, which we have also supported in operation for many years. We are also involved in the preparation of numerous other national and international projects.
  • We offer the following services in particular:
    • Financial modeling - creation of economically, technically and energetically integrated. profitability simulations with variable project parameters.
    • Sensitivity and scenario analyses, Monte Carlo simulation, risk assessment.
    • Economic due diligence.
    • Company valuation in the geothermal industry.
    • Price escalation clauses, price calculation and price review for heat suppliers and heat customers.
    • Short / medium-term liquidity and business planning.
    • Development of risk management concepts in cooperation with project management, technical partners and specialized insurance brokers.
    • Project controlling.

Financing and funding

  • The SONNTAG Geothermal team supports numerous deep geothermal projects in the structuring of project financing and the procurement of subsidies. We have negotiated bank financing of over 300 million euros on the basis of "stress-testable" profitability simulations and obtained more than 60 million euros in funding from KfW and state institutions.
  • We prepare the funding applications and also provide evidence management for the funding institutions.Since state funds are used for municipal projects, we design financing solutions that comply with regulatory and EU state aid law and, if necessary, also support the project in the notification process.
  • We offer the following services in particular:
    • Advising geothermal projects on project and corporate financing and optimizing the financing structure with regard to rating, key figures and collateral, etc.Support in choosing a legal form that is favorable for financing
    • Reviewing, drafting and negotiating financing and collateral agreements with banks, syndicates and investors.Funding advice and application management for relevant funding programs, including support in the proof of use procedure.EU state aid law review through private investor tests and drafting of entrustment acts.

Due Diligence

By conducting an analysis and assessment as soon as possible of the numerous legal, tax, and economic aspects relevant for a real estate transaction, potential risks and important stipulations can be recognized and considered in a well-ordered manner within the further transaction process, both for the acquisition and also for the sale of a property. For this reason, we recommend to our clients that they conduct a due diligence assessment (legal, tax and if necessary, financial due diligence) prior to commencing with contract negotiations, in which case we of course coordinate the precise scope and depth of the assessment with our client in advance, and adjust this assessment to individual requirements.

Geothermal competence

  • The SONNTAG geothermal team is driving forward the electricity and heat transition. Since 2004, the team has acted as a central business and legal consultant for deep geothermal projects with a total thermal output of over 200 MW and an investment volume of over 500 million euros.
  • The range of consulting services primarily includes classic deep geothermal projects with drilling depths of 3,000 to over 5,000 meters for power generation and district heating supply with extensive network construction.
  • Business economists and lawyers work successfully hand in hand in the team. With a great deal of passion and expertise, we have already supported over 60 geothermal projects in the booming region of the Bavarian Molasse Basin, the North German Basin, the Upper Rhine Graben and abroad.
  • The team is well connected with many other geothermal experts, such as geologists, engineers and insurance brokers, some of whom have been promoting the use of geothermal energy in Germany "from the very beginning". The team works independently with all geothermal experts.

Drilling contracts

  • In dialog with clients and planners, we draw up contracts for all services relating to deep drilling. We negotiate the contracts in bidding and award procedures and support our clients in the review and evaluation of bids. The contracts are continuously developed and adapted to legal and market developments.
  • From working with geologists and drilling engineers and from handling claims, we have the necessary understanding of the technical processes, interfaces and risks that are addressed in the contracts.
  • The wells tap into the energy source and represent an investment in the double-digit millions. It is crucial for the success of the project to commission highly qualified companies at fair conditions. The SONNTAG geothermal team has extensive experience in this selection process, including special contracts for all variants of commissioning deep drilling work. These contracts are tailor-made: clear regulations on remuneration, performance deadlines, defect rights, security deposits and a concept for conflict resolution in the event of legal or technical disputes are important.
  • The remuneration regulations (operating, waiting and waking hours) must be so precise that the client only pays for services actually rendered. The service deadlines must be carefully coordinated to avoid cost-intensive downtimes and other disruptions. Liability and warranties for deep drilling work differ greatly from those in the construction industry and are negotiated intensively between the parties involved.
  • We advise the client in close consultation with the geologists and drilling engineers on the appropriate procurement or contract concept: general contractor concept for the procurement of deep drilling from a single source or commissioning of all trades for deep drilling separately or a middle ground: combination of general contractor package(s) and individual contracts.
  • We have contracts for every procurement concept that we have drafted and that have proven themselves in the market from a large number of negotiations. We always adapt our contracts to the client's needs. We know the players and their scope for negotiation. If required, we can also draft and negotiate contracts in English.
