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.

Pre-feasibility studies for renewable energy-based Mini-Grids and Energy Centres in Lesotho

Currently, approximately 60% of Lesotho households do not have access to the electricity grid. In the currently ongoing project „Development of Cornerstone Public Policies and Institutional Capacities to accelerate Sustainable Energy for All (SE4All) Progress“ investments in renewable energy-based mini-grids and energy centres will be catalysed. The project is expected to implement ten mini-grids and ten energy centres in 20 villages spanning five of ten Lesotho’s districts.

Together with the local partner KRATOS Dr. Langniß – Energie & Analyse composed pre-feasibility studies for five Lesotho’s districts, where current situation regarding energy supply and consumption in every village was described, potential of renewable energy sources and future development of energy demand were assessed, and possible variants of the energy supply were proposed. The project partners carried out interviews of households, institutional and business customers in every village, in order to identify current and future energy consumption, income level, as well as willingness to pay for energy services. Design of Mini-Grids and Energy Centres was developed in the software tool HOMER Pro. LEA calculated profitability values for every energy supply option. The project partners presented the study results on the stakeholder meeting in Lesotho.

Pre-study on the blockchain applications in an innovation district

An innovation district with offices for up to 10,000 people will be constructed within a large German metropolitan area till 2025. On site, an area of 90,000 m2 will be developed with a floor space of 241,800 m2. It includes 3,000 parking spots, 1,400 of them will be equipped with charging points. In addition to commercial and office spaces, living spaces for temporary and permanent residents will be provided. Electricity will come from PV plants in the district and the neighborhood and stored in the battery storage over time.

In this context, there is a special interest in opportunities of using blockchain technology. In a short study under contract from OLI Systems GmbH, Dr. Langniß – Energie & Analyse analyzed the potential based on specific applications, which are applicable to the innovation district. To these applications belonged tokenization of (energy) services, smart charging of electric vehicles, heat utilization and storage, battery storage, as well as PV (self-generation & integration of external plants). Economic efficiency of different applications and synergies between them were demonstrated. The study results were presented at an internal workshop with the customer and at an investor meeting.
