“…Unfortunately, until now, despite the attractiveness of its current FiT system, investors are discouraged and the country's PV market is far from mature, as Carvalho, Wemans, Lima, and Malico (2011) reasonably support. On the basis of available data (EurObserv'ER, 2011), Portugal is in the 9th place, beneath Slovakia, Greece and Belgium, with 130 MWp installed PV systems, which became more efficiently promoted, mainly by FiT since 2007.…”

One of the most promising renewable energy technologies (renewable energy sources, RESs) is photovoltaics (PVs). PVs are a truly elegant means of producing electricity on site, directly from the sun, without concern for energy supply or environmental harm. They represent a favorable case: easy and fast installation, low maintenance requirements and the ability to produce electricity on site within the urban built environment. In that sense, there is a growing consensus that PVs for individual buildings, known as building integrated or applied PVs (BIPVs or BAPVs, respectively), will be chief among the continuously widespread distributed PV applications. Still, they suffer from the disadvantage of their very high initial cost compared to other renewable and conventional energy technologies, although this has been steadily reduced during the last 5 years. It is therefore evident that without the support of suitable instruments, the expansion of solar electricity worldwide would not take place at a satisfactory pace. Various effective support mechanisms have been adopted, within which feed-in tariff (FiT) proved to be the most successful for PVs. That is the case also in Greece, where the PV market in the building sector grew rapidly after 2009, due to the great FiT incentives granted particularly for residential applications. In this paper an overview is provided, accompanied by a comparative feasibility study regarding residential PV systems' prospects, based on the review of all kinds of incentive schemes in EU for small-scale BAPVs.

“…Before 2011, the lack of specific regulations for mini-generation systems limited photovoltaic diffusion as the feed-in tariffs settled in 2007 by the Decree-Law No. 225/2007 have not been listed explicitly, being calculated monthly for each system based on avoided costs, which leads to administrative difficulties as well as low transparency [33].…”

An Overview of the Portuguese Energy Sector and Perspectives for Power-to-Gas Implementation

2018

Energy policies established in 2005 have made Portugal one of the top renewable power producers in Europe, in relative terms. Indeed, the country energy dependence decreased since 2005, although remaining above EU-19 and EU-28 countries in 2015 (77.4% vs. 62.4% vs. 54.0%, respectively). Data collected from governmental, statistical, and companies’ reports and research articles shows that renewables and natural gas assumed a growing importance in the Portuguese energy mix along time, while oil followed an opposite trend. Recently, the country remarkably achieved a full 70-h period in which the mainland power consumed relied exclusively on renewable electricity and has several moments where power production exceeds demand. Currently, the main option for storing those surpluses relies on pumped hydro storage plants or exportation, while other storage alternatives, like Power-to-Gas (PtG), are not under deep debate, eventually due to a lack of information and awareness. Hence, this work aims to provide an overview of the Portuguese energy sector in the 2005–2015 decade, highlighting the country’s effort towards renewable energy deployment that, together with geographic advantages, upholds PtG as a promising alternative for storing the country’s renewable electricity surpluses.

“…Therefore, during the last decade, concerns about global climate change, finite conventional resources, and decreasing costs of renewables have been major arguments to justify the inclusion of RES and energy-efficiency policies in a significant number of countries [5]. In fact, most developed countries have been promoting policy principles and incentives to turn efficient and renewable scenarios into reality, and several are pushing for major renewable energy integration [6], [7]. In this context, and aiming to reduce dependence on fossil fuels and foreign energy sources, electricity emerges as a sector wherein renewable energy policies and energy-efficient initiatives are most likely to be implemented because it can be generated from a large variety of fuels and technologies.…”
