Photovoltaic energy in Portugal

In Portugal electricity represents around 20% of final energy consumption, of which 30% to 40% is renewable-based, mainly large hydro plants. Of the renewable technologies, wind power has been growing fastest over recent years. Targets exist for new renewables: for wave power a pilot area will be chosen for testing different concepts.

Portugal is developing actions to increase and improve the environmental issues in the energetic laws, with base in the “Estratégia Nacional para a Energia” - RCM n.º 169/2005 (Energetic National Strategy). In this context, all the efforts are to look for a more sustainable energy using the best available technology and, in long term, to support the development of new technologies.

According to the Directive 2009/28/EC of the European Parliament and of the Council on the promotion of the use of energy from renewable sources the target for the share of energy from renewable sources in gross final consumption of energy in the year 2020 for Portugal is 31% (in the year 2005 the share was 20.5%). The Directive has a mandatory 10 % target for transport to be achieved by all Member States, which refers to renewable sources as a whole, not biofuels alone.

Renewable energy projections according to the National Renewable Energy Action Plan for Portugal
The National Renewable Energy Action Plan (NREAP) for Portugal was submitted in August 2010. The target according to Annex I of Directive 2009/28/EC is 31% for the year 2020 and the projected NREAP share in that year exactly matches the target.  According to the projection, the most important contribution in the year 2020 is expected from biomass (renewable heating and cooling) (2322 ktoe, 38% of all renewable energy). Second important contribution is expected from wind power (14.6 TWh or 1255 ktoe, 21% of all renewable energy). The third largest contribution is from hydropower (14.1 TWh or 1210 ktoe, 20% of all renewable energy). Wind power contributes with 6.9 GW (14.6 TWh) in the year 2020 (onshore wind 6.8 GW and 14.4 TWh, offshore wind 0.1 GW and 0.2 TWh). For solar photovoltaic the 2020 contribution is projected to be 1.0 GW (1.5 TWh). For solar thermal the 2020 contribution is projected to be 160 ktoe. The two most important biofuels are projected to contribute 450 ktoe (biodiesel) and 27 ktoe (bioethanol / bio-ETBE) by 2020. The renewable electricity production from solid biomass amounts to 1.5 TWh (126 ktoe) and for biogas it is expected to be 0.5 TWh (45 ktoe). The consumption of renewable heat is expected to amount to 1484 ktoe for solid biomass and 37 ktoe for biogas.

Renewable electricity: photovoltaic energy (PV)
According to the feed-in tariff programme of the Decree Law 33-A/2005 of 16th February 2005 the level of the feed in tariffs in 2007 were: for installations < 5 kW: 45 € cents/ kWh and for installations > 5 kW: 31 € cents/ kWh. More recently, with Decree Law 225/2007 new tariffs were introduced for emerging technologies such as solar thermal power and wave power. For PV installations < 5 kW the tariff remained 45 € cents/ kWh and for installations > 5 kW the tariff it is 31.7 € cents/ kWh. Solar thermoelectric installations up to 10 MW receive 27.3 € cents/ kWh. The tariffs are guaranteed for a period of 15 years or in the limit of a production of 21 GWh per MWp, after which the market electricity price is the remaining income.
