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.
Tasks:
- Development of an economic and financial model to determine the profitability of the biogas power plant
- Consultations with the client and the project manager

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.
Tasks:
- Pre-feasibility studies
- Energy system modelling
- Questionnaire drafting and survey supervision
- Presentation of results for stakeholders

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.
Tasks:
- Pre-study
- Process modelling
- Economic efficiency calculation
- Presentation of results for customer and investor

Sector coupling and neighborhood with blockchain tokens for an innovation district – outline preparation for idea competition „Living labs of energy transition“
In an innovation district in development within a German metropolitan area an integrated and interactive energy concept is put into practice. Data driven technologies will be applied in a system facilitating manner. As such they will get analyzed: a building information model (BIM), high resolution (by time) measurement and control concepts for energy management and blockchain for agent-based trade of energy resources. Energy supply will comprise a set of completely renewable based components, such as PVT collectors for combined electricity and heat production, a low ex system for combined heating and cooling as well as the development of optimized operation strategies applying artificial intelligence. A blockchain technology-based market place will be created where players or assets in the district or from the neighborhood can carry out energy related transactions in an automated manner. Sustainability tokens are supposed to incentivize and reward sustainable behavior in the sense of a district’s currency.
The project leader for the district’s development charged Dr. Langniß - Energie & Analyse with the coordination of a funding project outline for the idea competition of the German federal ministry for economics and energy (BMWi). A consortium of eight partners, technology companies as well as research organizations and a regional manager being part, outlined the project collaboratively.
Tasks:
- Draft of the funding project based on the urban management plan for the district
- Acquisition of additional partners in the environment of the consortium consisting of both enterprises and research partner
- Coordination of the whole process of outline preparation and submission
