“…At the same time, depending on how the different governments decided to levy the RES subsidies, electricity retail prices increased. As a result, solar PV has reached 'grid parity' in many countries in recent years (Khalilpour & Vassallo 2015;Hagerman et al 2016;Karakaya et al 2015;La Munoz et al 2014; Bardt et al 2014). This means that in these countries self-consumption of the electricity generated from PV became more attractive than feeding the electricity into the grid and getting paid the subsidy.…”

What drives the profitability of household PV investments, self-consumption and self-sufficiency?

Many countries introduced subsidy schemes that were successful in incentivising investments into residential solar PV. The resulting growth of the global PV market was accompanied by cost reductions for PV systems, reductions of PV subsidies and, often, increasing electricity retail prices. Along with decreasing costs for battery storages, these developments made self-consumption and self-sufficiency continuously more attractive. However, the profitability of PV-storage systems depends on many factors, including technological, political and geographical aspects. We present a simulation model to identify the most profitable sizes of PV and storage systems from a household perspective and explore what drives the profitability of self-consumption and self-sufficiency. We compare and contrast Germany and Ireland to account for regulatory and geographical differences. Our results show that PV-storage systems are generally profitable in Germany and that, after minor technology cost reductions, this result holds even in the absence of subsidies. In Ireland, such systems are not yet profitable but this may change soon with expected technology costs reductions. The share of electricity demand that will be required from the grid may be reduced to 25-35%. Implications for the electricity retail business and policy makers are discussed including distributional concerns and system efficiency considerations.

“…Summaries of our sample's socio-demographics, housing characteristics, and energy and financial matters are given in the appendix. Bardt et al (2014) estimate that in the time period 2008 to 2012, electricity self-supply in the German residential sector (prosumer households) rose from 0.0% to 1.3%. The simulation study by Bardt et al (2014) is based on EEG remuneration for PV systems, which seems reasonable in light of the high share of PV systems in MGT systems.…”

The simulation study by Bardt et al (2014) is based on EEG remuneration for PV systems, which seems reasonable in light of the high share of PV systems in MGT systems. However, until 2012 the price structure of electricity had not incentivized prosumer households to consume self-generated electricity, 7 because the price of electricity from the grid was lower than the guaranteed feed-in tariffs (see figure 1).…”

Prosumer Preferences Regarding the Adoption of Micro-Generation Technologies: Empirical Evidence for German Homeowners

This paper investigates the preferences of homeowners in Germany regarding the adoption of renewable energy-based micro-generation technologies using data from a survey with a discrete choice experiment. In the German policy debate, private households, in their possible joint roles as electricity producers and consumers, are discussed as potential key actors for the transition of the energy system towards a decentralized energy market based on renewable energies. In our study, we address the relevance of investment and usage characteristics as well as the perceived importance of both private and social costs and benefits behind prosumer preferences for the adoption of generic electricity micro-generation technologies. The empirical investigation is based on a conditional logit model. The results show the perceived usefulness of electricity self-supply, indicating that the motivation for electricity "prosuming" is about more than just using green electricity and undertaking a profitable (energy) investment. Policy makers should not rely on the intrinsic motivation of households to contribute towards climate protection but instead take social effects more strongly into account in their policies which aim to foster the energy system transition ("Energiewende"). Further, both energy policies and business models should avoid the introduction of overly complex measures which might be too demanding on households.

“…These changing conditions have created increasing economic challenges Sustainability 2022, 14, 7545 2 of 17 for prosumers, who need to decide if they are to continue running their PV plants or shut them down. On the other hand, social challenges, in particular regressive effects, have arisen from unevenly distributed opportunities to reap the benefits of prosumage (most notably between building owners and tenants) [6]. Prosumage is most likely implemented by consumers belonging to the upper income segments, who own a house with the possibility to install PVs.…”

Business Model Innovations for Renewable Energy Prosumer Development in Germany

et al. 2022

In Germany, the number of renewable energy prosumers has increased rapidly since 2000. However, the development of prosumers has faced and will continue to face various economic, social, and technological challenges, which have triggered the emergence of a number of innovative business models (BM). This paper enriches the empirical basis for prosumer-oriented BMs by investigating two BM innovations in Germany (P2P electricity trading and aggregation of small-size prosumers) drawing on business model and socio-technical transition theories. A mix of qualitative data collection methods, including document analysis and semi-structured expert interviews, was applied. We found that while both BMs can potentially address the challenges associated with renewable energy prosumer development in Germany, small-scale prosumers’ participation in both BMs has been limited so far. We identified various internal and external drivers and barriers for scaling up these BMs for prosumer development in Germany. Despite these barriers, both aggregation and centralized P2P targeting prosumers may potentially be also taken up by incumbent market actors such as utilities. Decentralized P2P on the other hand still faces significant internal and external barriers for upscaling. Based on the analysis, the paper provides policy recommendations with respect to the identified drivers and barriers. From a theoretical perspective, our findings provide further evidence to challenge the dichotomous understanding of niche actors and incumbents, the latter of which are often theorized to be resistant to radical innovations.
