C/sells – Smart Grids for the Energy System of the Future – project development and deputy project coordination

C/sells as an extensive show case project creates an east-west-solar arc connecting solar energy dominated "energy cells" solar cells with Baden-Wuerttemberg in the center. Due to the high solar generation and the mix of urban and rural areas, Baden-Wuerttemberg is predestined for the project. Furthermore, a diverse interaction pattern provides optimal conditions in order to implement new cooperation models.

In December 2015, C/sells was selected as one out of five demonstration projects within the German Ministry of Economy’s SINTEG (“showcase intelligent energy”) call. The project length is four years starting at January 2017.

Dr. Langniß – Energie & Analyse compiled a consortium with over 60 partners from business and academia. A detailed draft had been developed coordinating the comprehensive input of the partners. The draft presented the project’s content, approach, cost structure and organization with an overall scope of 100 million Euros.

Dr. Langniß – Energie & Analyse coordinated the complex application process of C/sells. Therefore, the draft was consolidated into a full proposal which represents the working basis for the four years of the project.

During the execution of the project, Dr. Langniß – Energie & Analyse is the deputy project coordinator.

Within its part of the project Dr. Langniß – Energie & Analyse develops and refines the open-source soft- and hardware OLI for peer-to-peer communication, coordination and energy exchange based on the blockchain and Ethereum and pilots this. This will make possible a small-scale balancing of consumption and production as well as an enabling of trading with small-scale local and regional flexibilities. LEA develops concepts for the use cases on certificates of origin, balancing group management, smart charging of electric vehicles as well as peer-to-peer matching. With the conception and pilot testing of blockchain in the outlined applications important references for the standardization of blockchain technology for the purpose of market and network communication will be derived. On the base of experience with pilot tests and demonstrations possible, necessary or desirable regulatory developments can be concluded. The objective is besides, to implement the blockchain technology as comprehensive as possible with other partners in C/sells.

Evaluation of Energy related programme outlines

Since 2008, the Federal German Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) has been funding climate change mitigation and biodiversity conservation programmes in developing and newly industrialising countries through the International Climate Initiative (IKI). The IKI-Secretariat is managed by the non-profit company The Zukunft – Umwelt – Gesellschaft (ZUG) gGmbH.

In March 2019 the current IKI thematic-oriented selection procedure has been launched. The selection procedure aims to find programme outlines for 12 thematic funding priorities. The IKI has earmarked 240 million euros in funding for the selected programmes. Programmes can each receive funding of 5 to 20 million euros.

Dr. Langniß – Energie & Analyse reviewed nine outlines from two thematic funding priorities “Energy transition: efficient use of renewable energies including sector coupling” and “Just Transition of coal to renewable energies” with the emphasis on the coherence of the consortium, relevance for country priorities, feasibility, scalability and impact of the project concept, as well as financial efficiency. Additionally, factsheets on the applicant consortia and donor landscape analyses were prepared. The results were presented to the client and a synthesis report submitted.

  • Research on the capacities of the applicants and the donor landscapes
  • Presentation of results to the client
  • Drawing up the synthesis report

Prefeasibility study for construction of a biogas power plant in Bamako, Mali

Mali has an average electrification rate of only 35%. Building an environmental-friendly energy system is essential and funded by the government. In this context, the National Agency for the Development of Biofuels (ANADEB) in collaboration with the private company Catalyze has decided to construct a biogas power plant in Bamako. Prior to the construction of the power plant, a pre-feasibility study is required to determine the technical feasibility and cost-effectiveness.

Dr. Ole Langniß, as a senior economist, has identified project costs and developed an economic and financial model for the pre-feasibility study.


  • Development of an economic and financial model to determine the profitability of the biogas power plant
  • Consultations with the client and the project manager
