The areas, spread across mainland Portugal, have been selected for their renewable energy potential and suitability for development. Together, they account for around 1% of the country’s mainland territory.

The idea is fairly straightforward: identify suitable locations in advance so that projects proposed there do not have to go through the same lengthy approval process all over again.

Minister of the Presidency António Leitão Amaro said projects within the designated areas will benefit from shorter licensing periods and, in certain circumstances, simplified environmental procedures.

The Government hopes this will remove one of the biggest obstacles facing new renewable energy developments in Portugal: the time it can take to move a project from investment proposal to actual construction.

Not every suitable site made the cut

The final map is the result of a public consultation and takes more than energy potential into account.

Environmental restrictions, agricultural land, water resources, cultural heritage, defense requirements and existing infrastructure were among the factors considered before areas were included.

This is an important distinction. The designation of more than 800 zones does not mean hundreds of wind and solar developments have now been approved. Instead, the areas have been identified as places where future projects could face a simpler route through the planning and licensing system.

Portugal has been pushing to increase domestic renewable energy production as it works towards its climate targets, while also seeking to strengthen energy security and reduce dependence on imported fossil fuels.

The Government says faster licensing is essential if the country is to turn its considerable solar and wind resources into additional electricity generation without abandoning environmental and planning safeguards.

The next test will be what happens on the ground. Identifying suitable areas may speed up the paperwork. However, new renewable projects will still have to contend with issues ranging from access to the electricity grid to local concerns over how developments affect landscapes and communities.

For now, the 800-plus zones give developers what they have long asked for: a clearer idea of where Portugal wants the next generation of renewable energy projects to be built.
