“…However, this is unrealistic as also other measures could be used to avoid negative prices. In 2016, negative prices occurred during 97 h with a trading volume of €68.7m (Aust and Morscher, 2017). That means that one hour of spill-over energy may cost up to 708,247 Euros which in total means savings of €75.43m.…”

Purpose The purpose of this study is to analyse the contribution of shifting the load of household devices from periods of renewable energy underproduction to surplus periods in order to better match energy production and demand. Design/methodology/approach An optimisation model for load shifting of household devices is developed and analysed with the help of a simulation of energy loads for the year 2030 in Germany. Findings About 1.48% of the renewable surplus energy can be used in addition which equals total savings between €15.06m and €106.71m. However, 24.47% of the surplus periods can be compensated completely and 6.38% up to a level of 94%. Research limitations/implications A 100% diffusion of smart metres and devices and a high acceptance among consumers are assumed so that the results of this study present an upper bound for the contribution of household load shifting. Practical implications Load shifting of household devices provides only a small contribution and can only be one measure among others. It is crucial to find and invest in new energy storage systems so that more renewable spill-over energy can be used. Originality/value An optimisation model for load shifting is developed. Customer behaviour and devices are considered individually and not only a fixed percental share. Beside peak load periods also periods of renewable spill-over energy are considered.

“…The invert relationship between price and supply results in dramatically depleting, sometimes even negative, electricity prices in cases of unexpected oversupply caused by weather changes, that are often difficult to predict. Regulation to incentivize renewables, such as priority dispatch of renewables into the grid, worsens the resulting economic inefficiency [5]. Given the latest political endorsement for PV and wind energy in major economies, both effects are expected to worsen if not controlled for as the share of vRES is on the rise in the foreseeable future [1].…”

An Empirical Study of How Household Energy Consumption Is Affected by Co-Owning Different Technological Means to Produce Renewable Energy and the Production Purpose

The transition from fossil fuel-based to renewable energy sources is one of the main economic and social challenges of the early 21st century. Due to the volatile character of wind and solar power production, matching supply and demand is essential for this transition to be successful. In this context, the willingness of private consumers to use energy flexibly has gained growing attention. Research indicates that a viable driver to motivate consumers to be demand flexible is to make them (co-)owners of renewable energy production facilities. However, existing research has only analyzed this question from an aggregated perspective. This article analyses whether behavioral changes triggered by (co-)ownership in renewables differ according to the type of installation; be it solar, wind, or bioenergy. In addition, the prosumption options self-consumption/self-consumption and sale/sale are considered. To do so, we collected 2074 completed questionnaires on energy consumption that entered an econometric model using propensity score matching to control for estimation biases. We find significant differences in the willingness to consume electricity in a flexible manner for (co-)owners of solar installations. However, only the usage of household appliances proves to be statistically significant (p-value = 0.04). Furthermore, the results show that within the group of (co-)owners of solar installation, the choice between self-consumption and sale of the produced energy has a significant effect on the inclination to become demand flexible (p-value ≤ 0.001; p-value = 0.003).

This article weighs up the costs and benefits of the expansion of renewable energy technologies for electricity generation in Germany. According to calculations of the German Ministry of Economic Affairs, this expansion has cost electricity consumers almost 300 billion euros since the introduction of the Renewable Energy Sources Act (EEG) in 2000. Moreover, payment obligations of a similar magnitude are already in place for the next two decades. However, with the accelerated expansion of renewables following Russia’s attack on Ukraine, politicians are accepting costs well in excess of this approximately 600 billion. Given the costs already incurred, a cost-benefit analysis is imperative, not least because further costs in the three-digit billion range are not included in the 600 billion figure, such as the costs for grid expansion, which would not be necessary to the same extent without the expansion of renewables. Against this backdrop, strict attention should be paid to cost discipline in the further expansion of renewables by ensuring that the Federal Network Agency only issues technology-neutral rather than technology-specific tenders for the expansion of renewables in future. This means that only the most cost-efficient renewable technologies will be installed. Consequently, there will be budgetary scope for future investments that could boost the growth potential of the German economy more than the expansion of renewable energies. Contrasting with the high costs, the benefits of expanding renewable energies are modest. For example, the share of renewables in primary energy consumption in 2022 was only around 17 %. With such a low share, achieving greenhouse gas neutrality in 2045 with renewables alone appears to be a tremendous challenge.
