“…By taking the main German levies and taxes for self-generation and -consumption into account, the optimization results of McKenna et al [18] indicate a shift in the economically optimal level of electrical self-sufficiency with scale. The effect of the then current legal regime on the optimal design of a CHP is also highlighted by Merkel et al [19].…”

Involving residential actors in the energy transition is crucial for its success. Local energy generation, consumption and trading are identified as desirable forms of involvement, especially in energy communities. The potentials for energy communities in the residential building stock are high but are largely untapped in multi-family buildings. In many countries, rapidly evolving legal frameworks aim at overcoming related barriers, e.g. ownership structures, principalagent problems and system complexity. But academic literature is scarce regarding the technoeconomic and environmental implications of such complex frameworks. This paper develops a mixed-integer linear program (MILP) optimisation model for assessing the implementation of multi-energy systems in an energy community in multi-family buildings with a special distinction between investor and user; the model is applied to the German Tenant Electricity Law. Based on hourly demands from appliances, heating and electric vehicles, the optimal energy system layout and dispatch are determined. The results contain a rich set of performance indicators that demonstrate how the legal framework affects the technologies' interdependencies and economic viability of multi-energy system energy communities. Certain economic technology combinations may fail to support national emissions mitigation goals and lead to lock-ins in Europe's largest residential building stock. The subsidies do not lead to the utilisation of a battery storage. Despite this, self-sufficiency ratios of more than 90% are observable for systems with combined heat and power plants and heat pumps. Public CO 2 mitigation costs range between 147.5-272.8 e/t CO2 . Finally, the results show the strong influence of the heat demand on the system layout.

“…Bracke et al [16] researched the prerequisites for a self-sufficient energy supply and the necessary technologies for it. The assessment of the modifications in the German Combined Heat and Power (CHP) Act in 2016 with respect to technical, economic and ecological aspects is given by [17]. In [18] the requirements and consequences of an extensive heat transition towards a heat demand coverage based on renewable energies was analysed.…”

Feasibility analysis of a heat pump powered by wind turbines and PV- Applications for detached houses in Germany

In this study an intelligent energy supply system is developed. Energy is obtained by wind or solar radiation and stored to cover the electricity and heat demand of a detached house in Germany. For this a heat pump and a storage tank is used. The simulation shows strategies to integrate renewable energies in different regions of Germany while diminishing the need to turn off a wind turbine or feed energy to the grid. For this, the energy consumption in a single house is modelled. Different wind turbines and PV systems are introduced as an energy source. The profitability of these systems is calculated and compared to conventional systems with gas or oil. The analysis shows that at the moment small wind turbines are a feasible option for cover the energy demand under the given conditions. On the other hand, currently PV plants are not suitable for the heat demand coverage as the specific costs outgo the ones for conventional systems. Further research is necessary to look at different case scenarios, taking into account future climate developments.
