The new law could allow between 400MW and 600MW of capacity to be added to Portugal's existing 4.754GW, according to Lara Ferreira of the Portuguese renewable energies association Apren.
Although an inflation-linked tariff starting at closer to €70/MWh "would have been optimal, we now have the opportunity to push ahead with repowering projects," she told WPM.
However she said obstacles remained. These are in the form of obtaining finance in Portugal's current economic climate and the shortage of physical space in certain clusters.
Last week, EDP president António Mexia, said repowering makes "good sense under the new law, especially in the case of the oldest wind farms".
