a b s t r a c tIn times of great transition of the European construction sector to energy efficient and nearly zero energy buildings (nZEB), a market observation containing qualitative and quantitative indications should help to fill out some of the current gaps concerning the EU 2020 carbon targets. Next to the economic challenges, there are equally important factors that hinder renovating the existing residential building stock and adding newly constructed high performance buildings. Under these circumstances this paper summarises the findings of a cross-comparative study of the societal and technical barriers of nZEB implementation in 7 Southern European countries. The study analyses the present situation and provides an overview on future prospects for nZEB in Southern Europe. The result presents an overview of challenges and provides recommendations based on available empirical evidence to further lower those barriers in the European construction sector. The paper finds that the most Southern European countries are poorly prepared for nZEB implementation and especially to the challenge/opportunity of retrofitting existing buildings. Creating a common approach to further develop nZEB targets, concepts and definitions in synergy with the climatic, societal and technical state of progress in Southern Europe is essential. The paper provides recommendations for actions to shift the identified gaps into opportunities for future development of climate adaptive high performance buildings.

“…Once the scenarios have been defined, it is necessary to generate a model that simulates the matching of the price of energy, thus determining the inversely proportional relationship between the % of integration of renewables in the Pool and the price of the resulting energy [2][3][4][5][6].…”

“…This paper presents a global view of the effects of different renewable energy sources on the electricity pool [1] combining and complementing the analysis of the effects of five renewable sources: wind, photovoltaic, biomass, small hydraulic, and solar thermal. The ex-post economic analysis of photovoltaic power in the Spanish grid was analysed in [2] by modelling alternative scenarios. The analysis of wind power merit-order and feed-intariffs effect by a variability analysis of the Spanish electricity market was developed in [3], while [4] compared the influence of photovoltaic and wind power on the Spanish electricity prices by means of artificial intelligence techniques and [5] did a similar comparison of biomass, solar-thermal and small hydraulic power.…”

Spain is at the forefront of renewable energy worldwide with a great integration level in its generation mix. This has put Spain in the situation that other countries that support renewable energy will be in a short-medium term. However active measures to support renewable energy have been losing strength in recent times seeking to reduce the deficit. On the one hand, the bonus for each technology is different and, on the other hand, their integration level in the mix, and thus its influence on the Pool, is uneven. This work aims to provide information and conclusions about the actual economic impact of each renewable technology on the pool and the electricity tariff for the Spanish case. For doing so, simulation and artificial intelligence techniques are applied in order to model the energy pool and simulate the electricity prices in five fictitious scenarios that suppress out of the generation mix, respectively, wind, photovoltaic, biomass, small hydraulic, and solar thermal. This way, based on the simulation, and ex-post analysis can be developed in order to obtain conclusions and knowledge, useful for other countries as well as for future decision making in the Spanish power system.

“…Guerrero-Lemus et al [14] analyzed the benefits of Law 24/2013 of the Electrical Sector on insular systems where the new PV plants represented an opportunity to reduce electricity costs. Azofra et al [15] monitored returns on investments in the system of promoting PV technology, based on the bonuses received and the savings generated for the Spanish electricity market. They showed that an acceptable temporary distribution of new PV facilities could have maintained the economic sustainability of the feed-in-tariff system.…”

Review of the Legislative Framework for the Remuneration of Photovoltaic Production in Spain: A Case Study

2020

Spain is among the European countries with the greatest photovoltaic potential. During the first decade of the 2000s, Spain was a European leader in installed photovoltaic power and job creation in the renewable energy sector, strongly influenced by a very favorable regulatory framework and public subsidies at a time of economic growth. That situation would be completely reversed with the regulatory changes introduced in 2012 to combat the tariff deficit and the instability in the electricity supply system, problems accentuated by the economic crisis. The main objective of this study is to present an exhaustive review of the legislative changes that have affected photovoltaic energy in Spain. Using real data on electricity production and the remuneration of a typical photovoltaic plant, we show that there was a very significant fall in the economic returns that investors had come to expect, within a system that prioritized, first and foremost, the initial investment rather than the levels of electricity production. The changes to the legislative framework affecting a typical 100 kWp photovoltaic (PV) facility that entered into service before 2007 provoked a significant decrease of 8.7% in expected revenues, calculated from real data of production and income. These economic losses can be even higher, with a drop in revenue of almost 25% if the entire period of the installation’s useful life is analyzed. Public support for renewable energy is important for its introduction into the electricity market, but so is regulatory stability that offers investment security and predictability for maintaining investment and development in the renewable energy sector.
