PERSPECTIVES ON THE PROSUMER ROLE IN THE SUSTAINABLE ENERGY SYSTEM

Climate change and the ever-growing demand for energy are pushing us to find new ways to manage energy production, distribution, and consumption. This energy transition is enabled, for example, by the digitalization, decentralization, and democratization of the energy system. The energy system is already transitioning from fossil-fuel and large power-plant–based generation toward a flexible system based on renewable energy sources. Traditional transmission grids are being replaced by smart grids enabled by digitalization that facilitate bi-directional flows of information and energy. At the consumption end, smart energy meters, energy monitoring devices and applications, and renewable energy technologies such as solar photovoltaic and battery storages empower energy consumers to evolve into prosumers: the producers and consumers of energy. These prosumers, also referred to as active consumers and energy citizens, are envisioned to play an important role in the sustainable energy system in the future. While the energy prosumer role has gained more research attention during the past few years, plenty of gaps in completely understanding energy prosumerism still remain. This research focuses on studying the prosumer role in the sustainable energy system. I study the enablers and activities of energy prosumers and explore how the growing number of prosumers may influence the socio-technical energy transition. The research presents two main perspectives on prosumerism; it explores both the micro and macro-level influences on the energy prosumers. The main research fields of this study are sustainability transitions, innovation studies, and policy. Based on theory and literature review, a novel research framework synthesizing the theoretical concepts and earlier research related to prosumers is introduced. From the methodology viewpoint, a pragmatic research approach and mixed methods are used to explore the enablers for prosumerism as well as prosumer activities and their impact on the ongoing energy transition. The research results are displayed in the form of six articles published in international peer-reviewed journals and conferences. The first two articles make propositions about the prosumer role as part of the changing socio-technical energy and innovation system. The next two articles focus on understanding the micro-level impact on the energy prosumers and examine the producer–consumer, in particular, as a co-developer of energy-related innovations. The remaining two articles address the impact of macro-level policies on prosumers. Overall, this research contributes to the understanding of the energy prosumer role in the future sustainable energy system. Theoretical contributions are related to the novel research framework that combines the concepts from the socio-technical multi-level perspective, innovation studies, and policy research as well as offers a more pragmatic framework for inquiry in the context of the changing energy system to observe the prosumer role therein. A specific theoretical contribution is made to the technology acceptance model that is tested in the context of external policy influence. Furthermore, the research contributes to innovation studies and especially to the field of user-centric innovations by bringing new results for understanding the factors behind end users’ collaboration interests. Practical contributions of the study are related to the understanding of the micro-foundations of prosumer interests toward innovation co-creation activities. Practitioners benefit from evidence concerning the differences between consumers and prosumers, which may help them in designing products and services for these different categories. This improved understanding is necessary, for example, to accelerate the diffusion of renewable energy technologies that is crucial for the sustainability transition. Policy- makers may benefit from the findings related to the policy analysis that combines and compares different prosumer activities with policy mixes and calls for a more holistic and systemic approach for the development of the prosumer related policies. While prosumer research has increased during the past decade, many future research avenues for the topic exist. For example, more research on prosumer role as part of the sustainability transition can help in designing better policies as well as products and services for consumers and prosumers. Moreover, systemic activities, such as those related to the integration of electric vehicle smart charging into the power system combined with other prosumer activities, offer opportunities for researchers. Furthermore, research concerning novel prosumer-centric business models, for instance related to energy communities, is needed to accelerate the diffusion of sustainable technology solutions. -- Ilmastomuutos ja kasvava energian kysyntä ajavat meidät etsimään uusia tapoja hallita energian tuotantoa, jakelua ja kulutusta. Energiajärjestelmä onkin jo siirtymässä fossiilisten polttoaineiden ja suurten voimalaitosten tuotannosta uusiutuviin energialähteisiin perustuvaan joustavaan järjestelmään. Sähköverkot on transformoitu digitalisoinnin mahdollistamana älykkäiksi Smart Grid -verkoiksi, jotka pystyvät siirtämään sekä energiaa että dataa molempiin suuntiin tuotannon ja kulutuksen välillä. Kulutuspäässä älykkäät energiamittarit, seurantalaitteet ja - sovellukset sekä uusiutuvien energialähteiden teknologiat, kuten aurinkosähkö ja akkuvarasto, antavat energiankuluttajille mahdollisuuden kehittyä prosumereiksi eli energian tuottaja-kuluttajiksi (engl. prosumer = producer-consumer). Prosumereilla, joihin viitataan myös nimillä ”aktiivinen kuluttaja” ja “energiakansalainen”, on tulevaisuudessa tärkeä rooli kestävässä energiajärjestelmässä. Vaikka prosumerit ovat saaneet lisää huomiota tutkimuksessa viime vuosina, energia prosumerismin ymmärtämisessä on vielä paljon aukkoja. Tämä tutkimus keskittyy selvittämään prosumerien roolia osana kestävää energiajärjestelmää ja sen murrosta. Tutkin prosumereihin liittyviä mahdollistajia, prosumerien toimintaa osana energiajärjestelmää sekä vaikutuksia kestävän kehityksen energiamurrokseen. Tutkimus on luonteeltaan monialainen, yhdistäen innovaatiotutkimusta, transitiotutkimusta ja myös jossain määrin politiikantutkimusta. Tässä pragmaattisessa tutkimuksessa käytetään sekä kvantitatiivisia että laadullisia tutkimusmetodeja. Tutkimuksen tulokset esitetään liitteenä olevien kuuden vertaisarvioidun konferenssi ja -journaaliartikkelin avulla. Ensimmäiset kaksi artikkelia esittävät propositioita prosumerin roolista osana muuttuvaa sosio-teknistä energia- ja innovaatiopelikenttää. Seuraavat kaksi artikkelia keskittyvät ymmärtämään mikrotason vaikutusta näihin toimijoihin ja tutkivat erityisesti energiaan liittyvien innovaatioiden yhteiskehittämistä. Lopuksi kaksi artikkelia käsittelevät makrotason politiikkatoimien vaikutusta prosumereihin. Tutkimuksen pääkontribuutio on ymmärryksen lisääminen kuluttajan muuttuvasta roolista osana energiajärjestelmää. Teoriakontribuutiot kytkeytyvät uusiin tapoihin yhdistää keskeisiä teorioita kestävän kehityksen transitiotutkimuksesta, innovaatiotutkimuksesta sekä politiikan tutkimuksesta. Käytännön elämään vaikuttavat kontribuutiot liittyvät empiirisiin tutkimustuloksiin esimerkiksi tavallisten kuluttajien ja prosumereiden eroista. Tietämyksen lisääminen auttaa teknologia- ja palveluyrityksiä suunnittelemaan tuotteita ja palveluita, jotka sopivat erilaisiin tarpeisiin, joka voi edelleen auttaa nopeuttamaan uusiutuvaan energiaan liittyvien innovaatioiden leviämistä ja siten edistää kestävää kehitystä. Prosumer -tutkimuksessa on edelleen paljon tilaa uudelle tieteenharjoitukselle. Esimerkiksi energiayhteisöt ovat yleistymässä ja tutkimus niiden roolista osana energiajärjestelmää on vasta käynnistynyt. Tutkimalla energiayhteisöjä pystytään lisäämään ymmärrystä niiden vaikutuksesta esimerkiksi sähköverkkoon ja lainsäädäntöön. Toisaalta myös yksittäisten aktiviteettien ja ajureiden tutkimuksessa on vielä paljon mahdollisuuksia. Esimerkiksi systeemiset ja integroidut ratkaisut, kuten sähköautojen käyttäminen osana kysyntäjoustoa, tarjoavat hyviä tutkimusaiheita. Lisäksi erityisesti uudet liiketoimintamallit liittyen prosumereihin ja energiayhteisöihin kaipaavat selkeyttämistä ja kokeiluja sekä regulaation muunnoksia

Prosumer communities and relationships in smart grids: A literature review, evolution and future directions

Smart grids are robust, self-healing networks that allow bidirectional propagation of energy and information within the utility grid. This introduces a new type of energy user who consumes, produces, stores and shares energy with other grid users. Such a user is called a "prosumer." Prosumers' participation in the smart grid is critical for the sustainability and long-term efficiency of the energy sharing process. Thus, prosumer management has attracted increasing attention among researchers in recent years. This paper systematically examines the literature on prosumer community based smart grid by reviewing relevant literature published from 2009 to 2018 in reputed energy and technology journals. We specifically focus on two dimensions namely prosumer community groups and prosumer relationships. Based on the evaluated literature, we present eight propositions and thoroughly describe several future research directions

Understanding potential users of energy community information system:a thematic analysis

Abstract. The continuing global growth of energy consumers, the war in Europe, and climate change are the driving factors for energy revolution. One solution to this concerning issue has been the transformation of energy consumers to become energy producers. Prosumers can be grouped to establish energy communities. Prosumers, energy communities, and other distributed energy resources (DERs) are possible sustainable energy resources that can be connected to the smart grid. The literature review of existing research about smart grids, distributed energy resources, and energy communities, is conducted to gain a better understanding of the complex system and its stakeholders. The Second part of the literature review follows the behaviour of the potential smart grid users and its recent studies. The research questions focus on understanding energy prosumer’s perspectives on information system usage in order to discover the advantages and disadvantages of potential information system within an energy community context. The data were gathered from semi-structured interviews with people who voluntarily replied to application forms which were distributed prior to this study. Qualitative research methods were chosen to be used. A thematic analysis was conducted and as a result a thematic map in which two main themes, 15 sub-themes, and 25 codes were identified. It was discovered that positive user experience, desired functionalities, monitoring, economic benefits, user interface, beneficial information, and platform availability were the driving factors seen as an advantage of the potential information system. On the other hand, data leaks, undesired functionalities, energy community problems, and negative user experience were seen as disadvantages of the information system. This study contributes to the field of sustainable human-computer interaction and the findings of this thesis can be used as a foundation for future research and to design and develop the smart grids from the prosumer’s perspective. Due to several requests from participants, the text of the thesis has been written with accessibility in mind, so that the text does not require special expertise in the field of sustainable human-computer interaction

Prosuming Alone or Together: A Bisectoral Approach to Conceptualizing the Commons Prosumer

The aim of this study was to combine the concept of prosumerism with the theory of the commons to develop the concept of commons prosumer (co-prosumer) in distinction to private prosumer (p-prosumer). While the p-prosumer prosumes for himself, the co-prosumer creates a social environment for social capital. We use energy and agriculture as two cases in point to illustrate that the concept of the prosumer‘s role appears in different contexts with varying attributes such as self-efficacy, sufficiency, or autarchy. However, independence and socially fragmented structures might lead to less resilience, whereas dependence structures could confer collective benefits. We propose a building block to fill the gap in the prosumer setting and balance individual and collective interests. By positioning the p-prosumer on a commons-based foundation, we make more explicit the dependence structures that build communities or networks to showcase possibilities that pave the way for shared and socially innovative structures of self-empowerment for infrastructure decision-making at different levels

What is needed for citizen-centered urban energy transitions : Insights on attitudes towards decentralized energy storage

This paper aims to fill a research gap in the area of consumer-citizen attitudes to business models for decentralized energy storage, at the level of households and buildings. The study focuses on the interaction of such attitudes and their underlying motivation factors with socio-cultural, contextual factors. Self-determination theory (SDT) is used as a theoretical framework, to connect interpersonal and contextual factors, addressing the question of how contexts influence the motivation to support energy storage. Drawing on SDT, this study examines the role of autarky (independence from the energy system), autonomy (control over energy management) and relatedness (degree of sharing required) in this regard, embedded and interpreted in the socio-cultural local context of two demonstration sites in Sweden and Portugal. A mixed method approach is used. Quantitative survey data provides information on local social and cultural dimensions, followed by stakeholder consultation workshops that elicit participants’ views on different models of decentralized energy storage. The findings raise questions of how to improve autarky and autonomy for prosumers, while keeping the need for time investment low and provide flexibility regarding the required degree of interaction between prosumers. Implications for business models and policy support for citizen-centered sustainable urban energy systems are derived

Engineering Local Electricity Markets for Residential Communities

In line with the progressing decentralization of electricity generation, local electricity markets (LEMs) support electricity end customers in becoming active market participants instead of passive price takers. They provide a market platform for trading locally generated (renewable) electricity between residential agents (consumers, prosumers, and producers) within their community. Based on a structured literature review, a market engineering framework for LEMs is developed. The work focuses on two of the framework\u27s eight components, namely the agent behavior and the (micro) market structure. Residential agent behavior is evaluated in two steps. Firstly, two empirical studies, a structural equation model-based survey with 195 respondents and an adaptive choice-based conjoint study with 656 respondents, are developed, conducted and evaluated. Secondly, a discount price LEM is designed following the surveys\u27 results. Theoretical solutions of the LEM bi-level optimization problem with complete information and heuristic reinforcement learning with incomplete information are investigated in a multi-agent simulation to find the profit-maximizing market allocations. The (micro) market structure is investigated with regards to LEM business models, information systems and real-world application projects. Potential business models and their characteristics are combined in a taxonomy based on the results of 14 expert interviews. Then, the Smart Grid Architecture Model is utilized to derive the organizational, informational, and technical requirements for centralized and distributed information systems in LEMs. After providing an overview on current LEM implementations projects in Germany, the Landau Microgrid Project is used as an example to test the derived requirements. In conclusion, the work recommends current LEM projects to focus on overall discount electricity trading. Premium priced local electricity should be offered to subgroups of households with individual higher valuations for local generation. Automated self-learning algorithms are needed to mitigate the trading effort for residential LEM agents in order to ensure participation. The utilization of regulatory niches is suggested until specific regulations for LEMs are established. Further, the development of specific business models for LEMs should become a prospective (research) focus
