I – The Past

Renewable energy sources have assumed a key role in the Portuguese energy mix for the last decade, i.e., since the first steps of the undergoing liberalisation of the Portuguese electricity market. Within the European Union context – as implemented at national level – renewable energy generation growth is sought so as to improve security of supply, decrease energy dependency and reduce environmental impact including through the reduction of the use of fossil fuels in energy generation – among other aims pursued by the relevant policies.

Wind has been, since the early stages of diversification of the Portuguese energy mix, the preferred source of renewable energy, wind generated electricity representing, in 2016, almost a quarter of the country's total mainland energy demand1. Portugal was, in 2016, one of the European countries with most wind energy generating installed capacity, with 5046 MW2, within a total of 13046 MW of renewables installed capacity and an overall generation installed capacity of 19518 MW.

Although hydro electricity generation also evolved over the years and large hydro represents a higher share in the renewable electricity generation mix3, with offshore wind generation still being in its pre-commercial phase4 and after the Portuguese Government suspended attribution of rights for onshore wind projects in 2012, solar is now the it-renewable in Portugal.

II – The Present and the Future

Having reached an effective implementation of wind and hydro renewable energy generation projects to diversify the Portuguese energy mix – evidencing 57% of renewables in energy consumption (with an increase of 10% when compared to 2015) –, the Portuguese Government policies (departing from the latest National Action Plan for Renewable Energies for the 2013-2020 horizon) established that investment in solar is the next bet to be made towards such diversification as well as for the fulfilment of the EU set 20-20-20 goals5. In this framework, Portugal is targeting a 31% incorporation of renewable energy sources into final gross energy consumption and 10% of this in the transport sector. These objectives exceed those set forth in Directive 2012/27/ EU6 approving a common framework of measures to promote energy efficiency in the EU by 2020.

In this context, upon several modifications of the renewables legal framework since 2010 and in simplistic terms, the Portuguese renewable legal framework underwent (i) the review of the licensing framework aiming at a swifter and clearer procedure jointly with the end of feed-in-tariffs for new renewable energy generation projects which are to sell the energy so generated in organised markets (such as the OMIE – the Spanish Pole including the day and intraday markets for the Iberian Market) or bilateral agreements7 and (ii) the adoption of a 2014 regime8 providing for small-production units and self-consumption generation units which are to be associated to buildings and industry and mainly count on solar energy generation projects for implementation (although biomass is also an option being implemented) with or without connection to the public service electricity grid9.

Importantly, since 201310, the feed-in-tariff scheme (with guaranteed remuneration) no longer applies to new renewable energy projects11, although projects benefitting from this regime kept the feed-in tariff scheme for the initially granted period (usually of 15 years or limited to a certain amount of energy injected into the RESP) and were provided with the possibility to opt for an additional five or seven years intermediate guaranteed remuneration risk-mitigation regime by (i) paying a contribution aiming at the maintenance of the national electricity system until 202012 and (ii) accepting lower feed-in-tariffs, which are based on the daily average wholesale market price subject to a floor and cap.

Notwithstanding the end of the feed-in-tariffs, Portugal is now coming to the verge of having its solar photovoltaic installed generation capacity grow tremendously and several new projects are in the pipeline for licensing.

For comparison purposes, in 2010, the contribution of solar energy generation to the renewable energy sector was only 0.8%, with an installed capacity close to 150 MW. In the end of 2015 only 429 MW of photovoltaic installed capacity were actually licensed, this source representing circa 1.5% of contribution to the renewables sector13. 2016 brought an increase of 10 MW in photovoltaic generation installed capacity14 and additional 380 MW in the pipeline for project development pending completion of the relevant licensing requirementsin. A recent announcement from the Government stated that photovoltaic generation installed capacity in Portugal is forecasted to rise up to 900 MW by 2020.

All these projects are to secure offtake of the energy generated in the free market although some investors are having difficulties in contracting stabilised tariff offtake to secure projects' economic viability and bankability. Investment opportunities are thus not only in generation but also in renewables' electricity offtake, which should greatly contribute to liberalising the Portuguese energy market and setting the pace to the Iberian Electricity Market's growth and competitiveness.
