Spain needs to take “urgent steps” – including the introduction of incentives – to extend the life of its 23GW of onshore wind farms as almost half the country’s capacity will be 15 or more years old by 2020, according to the head of the Spanish Wind Energy Association (AEE).

Juan Virgilio Marquez, the AEE’s chief executive, told Recharge “it’s very important for us to make short-term decisions as we are now facing the last steps in the lifetime of many of these wind farms”, the majority of which use outdated technology.
