Renewable Electricity - 2016

The main milestones of the sector in Portugal during 2016.

Wind Index

The Wind Index (WI) aims to quantify the monthly electric energy production fluctuations coming from the wind resource around the historical average value.


It is based upon real wind farm production results, properly corrected in order to dissipate any operational unavailability effects. 

Parques Eólicos em Portugal

The e2p project - Endogenous Energies of Portugal is a collaboration between APREN and INEGI to develop a database of all the renewable energy power plants in Portugal with special regime, periodicly updated and available to the general public. 

Macroeconomic Impact of the Renewable Electricity Sector in Portugal

The renewable energy sector is assuming an increasingly important position in Portugal, as a result of the expression that its actors have assumed in the national energy panorama, which is an important contribution to the sustainable development of the Country, the creation of wealth and the generation of employment. Considering the context of the renewable electricity sector in Portugal, APREN promoted an analysis of the progress of the sector in the recent years, projecting its evolution until 2020 and 2030.


Study developed by APREN and Deloitte.
