Selected elements of the Neighborly Exchange of Energy – profitability evaluation of the functional model

Abstract

The inevitability and successive implementation of the elements of the European Union (EU) energy policy and the freedom of achieving the goals left in this regard for the member states should translate into actions taking the specificity of local markets into account, in order to carry out liberalization processes in a harmonious manner. In 2016, the European Commission published a package of guidance documents "Clean Energy for All Europeans" in the perspective of 2030, also known as the Winter Package. The recommendations contained in some of the documents assume the continuation of integration of markets in the national and regional dimension, setting ambitious targets in the field of decarbonization, the increase of energy efficiency and the increase of Renewable Energy Sources (RES) share in the energy balance of EU countries. The short time to carry out a thorough reconstruction of the energy-generating sector forces to seek solutions that are in line with the European Community recommendations and, at the same time, do not constitute an excessive burden for the national economy and legal order. One of the activities is to use the potential of micro-networks of local communities striving for energy independence based on their own energy sources and to create regulations enabling the neighborly exchange of energy. This mechanism works in the form of pilot projects in many locations around the world (Sonnen Group; Power 54 Ledger). The paper presents the concept of functional and analytical assumptions for an exemplary structure of neighboring prosumers along with the presentation of simulation results based on real generation and consumption profiles and the presentation of investment profitability indicators for the proposed functional model.

Coopetitive Nature of Energy Communities—The Energy Transition Context

“…Energy cooperatives operate on the basis of a prosumer system that consists of an energy settlement that is based on the so-called discounts. An energy seller only settles accounts with an energy cooperative for the difference between the amount of electricity that is introduced to the electricity distribution network and the amount of electricity collected from this network for its own needs by the cooperative (its members) in the ratio of the corrected quantitative factor of 1 to 0.6 (in the case of prosumers, depending on the power of the installation, the coefficients 1 to 0.8 or 1 to 0.7 apply) [24,25]. In other words, for 1 MWh of energy produced by the cooperative and not used at the moment by the members of the cooperative, i.e., fed into the distribution network (the network in this situation acts as a storage for energy not used by the cooperative), 0.6 MWh of energy can be obtained from it.…”

“…) by the Polish government, which were to convince public to use renewable energy, including photovoltaics (Wróbel et al 2019). A key element of the energy transformation in the country, in accordance with the Poland Energy Policy until 2040 (PEP 2020), is the estimated increase in photovoltaic capacity, i.e.…”

“…Irrational natural resource management is a problem in all developing countries, posing a threat to basic human activities [13]. The convergence of all life spheres is becoming comprehensive; changes in one system leads to changes in other systems; therefore, it is necessary to calculate the relationships among influencing indicators, in particular ecological components, on other systems [3].…”
