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.

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.

Scoping Mission on a Regional Strategy and Action Plan on Energy Efficiency in the Caribbean Community (CARICOM)

The Member States of the Caribbean Community (CARICOM) are mostly Small Island Developing States (SIDS), which share a number of challenges in their sustainable development. Energy intensity of the Caribbean is among the highest in the world. High unexploited energy efficiency potential exists in all elements of the value added chain of the energy sector (energy production, transmission and distribution, as well as end use). Previous attempts to increase energy efficiency on both national and regional level lack coordination and did not lead to the expected results. Therefore, the need to develop a regional policy and strategy on energy efficiency was recognized.

European Union Energy Initiative (EUEI) received a request from the CARICOM Secretariat in February 2016 for providing technical assistance to develop a regional policy and strategy on energy efficiency for the CARICOM Member States. To expedite the request, a scoping mission was conducted in order to evaluate the feasibility of the received request. The Scoping Mission provided an overview of energy sector of all CARICOM Member States as well as an understanding of challenges with energy efficiency measures in the region. Previous initiatives and projects on both regional and national level were assessed. The institutional capacity in the region was assessed.

Methods applied incorporate desk research and a survey among key stakeholders in the region through face-to-face, phone or Skype interviews.

The results including recommendations were documented in a report and a presentation. Terms of Reference for the development of a regional energy efficiency strategy were drafted.

Umweltbundesamt - Overview and oriented assessment of decentral energy management systems

The energy sector is in the state of radical change, driven by technical developments like (distributed) renewable energies, digitalization and political goals as climate protection and opting out nuclear energy. Within this process, only in Germany more than 1.5 million of decentralized power stations were developed, with a rising trend. These decentralized plants are increasingly equipped with intelligent control devices, which perform controlling tasks beyond the mere assurance of the functional capability of power stations. So, e.g. consumers and storage devices are settled in a such way that own consumption of electricity from decentralized plants will be maximized.

The short study, which was compiled together with Öko-Institut in Freiburg, provides an overview of decentral energy management systems and a classification in terms of their ability to support overall system integration. A representative selection of systems is evaluated qualitatively and in an exemplary way with regard to their impact on different areas of the electricity system. These includes the impact on the electricity grid, the flexibility needed in the system and effects on energy consumption. This is followed by an overview of relevant ecological and social sustainability indicators. In the outlook the open questions are outlined, which should be answered within the long study on this theme.
