Abstract:
Many countries plan to decarbonise their energy systems by increasing energy efficiency and expanding the use of renewable energy sources (RES). Such actions require significant investments in new energy infrastructures. While people are generally accepting of these infrastructures, opposition sometimes arises when these developments are sited at close proximity to people's residences. Therefore, it is important to understand what actually drives people's preferences for spatial proximity to different energy infrastructure technologies. This study examines the factors influencing people's proximity preferences to a range of different energy technologies using a cross-country econometric analysis of the stated preference data from an unprecedented survey conducted on nationally representative samples of the population in Ireland, the U.S. and Germany. The survey involved more than 4,500 participants in total. This paper presents the data and selected results from a generalised ordered logit model for each energy technology surveyed. These are; wind turbines, solar power technology, biomass power plant, coal-fired power plant and natural gas power plant. The results show that, in general, German and Irish citizens are willing to accept energy infrastructures at smaller distances to their homes than their U.S. counterparts. Moreover, attitudinal factors are found to shape people's preferences more consistently than any of the socio-demographic characteristics.

Abstract:
In this work, we study the profitability of energy storage operated in the Nordic, German, and UK electricity day-ahead markets during 2006–2016. During this time period, variable renewable energy sources (vRES) have been rapidly penetrating the markets and increasing the volatility of the residual load, which is often assumed to be associated with improving financial viability of energy storages. However, storage operator profits are not publicly available, in particular not at plant level. We therefore develop a linear optimisation model which maximises profits from arbitraging hourly prices and use the model output of profits and storage operating hours in further econometric analyses. This is a novel approach merging two strands of literature (optimisation and econometrics) in a single energy storage study. Specifically, we quantify and disentangle the effects of electricity demand, solar and wind generation, the spread between gas and coal prices, carbon emission prices and structural breaks on profits and operation of 1–13MWh/MW energy storages. Among others we find that solar generation is associated with lower profits but higher operating frequency of energy storages in Germany. Wind power generation is associated with positive effects on profits in the UK and Germany. vRES does not affect profits or operation of new Nordic energy storages.
