“…Social Capital focuses on the social and cultural frame conditions for the PED. Technical barriers or physical capital include the fact that there has not been much experience in managing reverse power flows from high PV generation in the system [1] and that the increasing number of prosumers (both collective and individual) could lead to overall grid costs increasing [12]. Barriers to Financial capital relate to the financial investment required to set up a PED.…”

“…A significant decline in the costs associated with PV production and innovative PV efficiency improvements, coupled with the high number of solar days makes a strong case for PV energy in Spain [1] to meet and exceed national energy requirements [2]. However, until 2018, regressive legislation (specifically RD900/2015) protected dominant market interests and penalized PV energy production.…”

To mitigate the effects of climate change, the European Commission created a Strategic Energy Technology Plan committing to forming 100 Positive Energy Districts (PEDs) by 2025. These are considered to potentially be major instruments for decarbonization in a just transition. This plan has led to some districts being defined as PEDs, although none have fully met the criteria to be a PED yet. Research shows that new forms of energy ownership and production, as could potentially be found in PEDs, could help reduce energy poverty, which affects a significant segment of the population, as households can reduce their energy expenditure as well as improve their energy behavior. This paper set out to shed light on the PED landscape, investigating the barriers and opportunities to PED creation in Spain and its potential to mitigate energy poverty. We conducted a literature review on community-owned energy in Spain, followed with expert interviews (energy researchers, stakeholders, and NGOs) who focus on sustainability issues in Spain. Results show a number of barriers (lack of knowledge and awareness, and lack of trust from consumers) and opportunities connected with the creation of PEDs. In conclusion, policymaker engagement and support play a key role in successfully implementing PEDs.

“…It is no less important to note that the authors also point out the possible risks of increased self-consumption with respect to integration costs. The study that shows how, regardless of the region or work zone chosen in Spain and whether or not the prosumer is paid, the performance is guaranteed [26] is interesting. This regional distribution of the study would facilitate the adoption of corrective measures at the legislative level depending on the area in which they worked.…”

“…Net Present Value, NPV : accounts for the present value of all economic flows in the useful life of the project according to Equation (26), in which F is the income of each annual period j updated to the initial year (Equation ( 25)), M is the maintenance expenses calculated in the initial year, C 0 is the initial investment (j = 0), n is the useful life of the installation, d is the discount rate or interest rate required of the investment, i the inflation rate and ∆p the rate of year-on-year increase in energy prices.…”

Simulation of Self-Consumption Photovoltaic Installations: Profitability Thresholds

et al. 2021

PV self-consumption can contribute positively to the spread of PV and, therefore, to the progress of renewable energies as a key element in a decarbonized energy model. However, the policies of each country regarding the promotion of this type of renewable technology is fundamental for their growth. Despite the high number of sunshine hours registered in Spain, self-consumption in this country has not been authorized until recently. In this new context, this work presents a systematic study of the profitability limits of a self-consumption PV installation under different conditions of installed peak power, orientation and inclination of the PV panels and level of obstruction of the installation. It was proved that, for the case of study (Córdoba, Spain), the maximum profitability was achieved for PV panels oriented to the south and with an inclination of 15° whereas the most unfavourable conditions are those of PV panels with an orientation and inclination of 180° and 90°, respectively. Furthermore, when the level of obstruction increases the maximum of the Net Present Value of self-consumptions PV installations decreases and this optimal value is achieved for installations with lower power. Finally, empirical adjustment equations have been developed to estimate the profitability parameters of self-consumptions PV installations as a function of their design variables.

Universities as centers for innovation by nature, can play a relevant role in serving as education hubs for citizens in energy, promoting individual and collective behavioral changes among community members. By collaborating with their own communities on the energy transition, universities can become more sustainable while providing firsthand experiences that can trigger new attitudes in their students and employees. In this framework, this paper explores ways to create partnerships to establish energy communities and promote shared photovoltaic energy facilities in an inclusive manner, emphasizing the social impact of such actions. Four public universities in Aarhus, Évora, Ljubljana, and Madrid are challenged to explore the avenues for turning this vision into reality. The paper describes the entire exploratory process and highlights the various barriers encountered.This article is protected by copyright. All rights reserved.
