Economical Analysis of Financial Supports for Large-Scale Photovoltaic PV plants in Eastern Europeen Union Countries

2010

Today, photovoltaic (PV) attracts considerable interest among renewable energy sources (RES), because of its potential to significantly contribute to the future of clean energies. However, PV development is strongly related to the support policies introduced by national governments. The modification or fading out of such support schemes can strongly influence the development of the PV market in any given country. Although the PV market in European developing countries is still quite small, it has been growing rapidly in recent years. Until 2006, the installation of small off-grid PV plants prevailed in eastern EU countries. Starting from 2008, large-scale on-grid PV plants have been put int…

Impatto delle nuove tariffe elettriche sulla diffusione del fotovoltaico in Italia

2019

L'articolo illustra i principali contenuti della recente riforma delle tariffe elettriche e valuta le conseguenze, in termini di convenienza economica, della riforma sulla diffusione dei piccoli impianti fotovoltaici a uso domestico.

ECONOMIC ANALYSIS OF SUPPORT POLICIES IN PHOTOVOLTAIC SYSTEMS: A COMPARISON BETWEEN THE TWO MAIN EUROPEAN MARKETS

2014

The development of the photovoltaic (PV) sector in the last decade was spurred by the implementation of various support strategies aimed at reducing the gap between PV energy cost and the energy price for conventional generation. The deployment of support policies has pushed the reduction of PV energy costs, but despite this PV is still not very competitive and its development still requires adequate support mechanisms, simple grid connection procedures, and so on. This chapter provides a technical-economic analysis of investments in PV systems, evaluating the positioning of the main European markets (Germany and Italy), with the purpose of highlighting the main differences in the implement…

Economic analysis on dynamic photovoltaic systems in new Italian "feed in tariffs" context

2013

Dynamic photovoltaic generators, based on the application of solar-trackers, are able to give an increment to the electric energy production from solar source. Their realization and maintenance costs are certainly higher than those of fixed ones. In this paper the Authors propose a method to estimate the increment of electrical energy generation that must be guaranteed by a dynamic photovoltaic generator, so as its realization could be more favorable with respect to that of a fixed generator one with the same rated power. This method, developed by means of classical economic indexes like the Pay-Back-Period and the Net Present Value, takes in to account the economic incentives for the PV sy…

An analysis of the price escalation of non-linear water tariffs for domestic uses in Spain

2015

Abstract Efficient and sustainable water resource use and management is becoming increasingly important, especially in regions under water stress. The use of increasing block pricing involving an escalation or progressivity of unit prices in tariff systems is an economic instrument that contributes to achieving this objective. More progressive tariffs are expected to contribute to a better allocation of resources and avoid their wastage. This article analyses the determinants of the price escalation of water supply tariffs in Spain, a country subject to a high water stress throughout most of its territory. The main objective is to discern whether differences in the degree of progressivity i…

An analysis of feed’in tariffs for solar PV in six representative countries of the European Union

2014

Abstract In this paper, after a brief review on the main support policies for Photovoltaic (PV) systems in Europe, the specific situations of six representative countries (France, Germany, Greece, Italy, Spain and the U.K.) are examined, with the purpose of highlighting the main differences in the implementation of the feed’in tariff (FiT) support policies adopted for PV systems. In particular, a comparison based on the calculation of economic indexes, as the Discounted Cash Flows (DCF), the Pay-Back-Period (PBP), the Net Present Value (NPV) and the Internal Rate of Return (IRR), for different sized PV systems shows that a specific FiT can sometimes be inconvenient for the producer and that…

Comparative analysis of different supporting measures for the production of electrical energy by solar PV and Wind systems: Four representative Europ…

2009

Abstract In the 9th of March 2007, the European Council decided a fixing goal of 20% contribution of the renewable energy sources (RES) on the total European electric energy production in 2020. In order to reach such an ambitious goal, all the European countries are adopting different support policies for encouraging the installations of RES-based generation systems. In this paper, after a brief review on the main support policies for RES in Europe, the specific situations of four representative countries (France, Germany, Italy and Spain) are examined, with the purpose of putting into evidence the main differences in the support policies adopted for Photovoltaic (PV) and Wind systems. In p…

Feed-in Tariffs for Grid-connected PV Systems: The Situation in the European Community

2007

Distributed generation demonstrates to be able to significantly influence the electric power system bringing considerable benefits to the quality of service and improving the energetic efficiency of the distribution network. In particular, in the last few years, distributed generation from renewable sources is considerably increased thanks to the many support policies promoted worldwide with the aim of facing the environmental issue and the problem of the permanent rise of prices of the fossil energy. In this contest the paper presents a study of the "feed-in tariffs" financing measure carried out, at present, in many European countries and responsible of the increase in these last years of…

Renewable energy evaluation in Italy and Brazil

2017

The aim of this study is a comparison among Italian and Brazilian electrical energy system with a particular focus on renewable energy sources. The energy sector has a key role in the sustainable development of a country, so it influences economic and political choices. The work would underline differences, common point among two country, specially, in this particular socio-economic period and it should emphasize that green economy could be a possible answer to the financial crisis. The work will be divided into four sections: Section I will introduce all details of the question; Section II will explain the renewable assessments for the countries, Section III will talks how renewable energy…
