Spain’s solar industry sees itself at a turning point. At the XII Foro Solar, organised by the industry association Unión Española Fotovoltaica (UNEF), sector representatives called for stronger integration of photovoltaics and storage into the national power grid.

UNEF President José Donoso stressed that the industry must be prepared to meet rising electricity demand, which is expected to surpass 70 gigawatts. This increase, he explained, comes from already allocated and planned grid connection points. “Most of these gigawatts are from companies relying on the cost advantages of photovoltaic energy.”
Grid stability: rules to integrate PV
A central topic was the role of photovoltaics in maintaining grid stability. With Spain’s recent update to grid operation protocol PO 7.4, this is set to change. For the first time, the new regulation will allow PV systems to actively participate in voltage control. Beatriz Corredor, president of grid operator Redeia, welcomed the new rules: “We are celebrating the approval of PO 7.4, which will enable renewables to control voltage—something we as grid operators have long been calling for.” Redeia has already started implementing the new requirements.
Storage key to the energy transition
Another key focus of the forum was the role of storage. In a dedicated panel discussion, participants highlighted how storage supports industrial decarbonisation and grid stability. The discussion addressed both battery storage and pumped storage solutions.

Alberto Nadal, deputy secretary for economic affairs of the conservative Partido Popular, described photovoltaics as “the backbone of Spain’s electricity system.” However, he noted that continued growth will depend on increased demand, better grid connections and expanded storage capacity.
Focus on EU component manufacturing
European manufacturing of PV components was yet another key topic. Against the backdrop of the EU’s Net-Zero Industry Act (NZIA), representatives from leading companies such as Sungrow, Arctech Solar, Gamesa Electric and Nextracker explored opportunities for competitive production in Europe. Still, securing financing for new projects remains a particular challenge. (nhp)
