Plenitude, the renewable-energy arm of Eni S.p.A, is underway with its new 200 MW Entrenúcleos solar park, located between Dos Hermanas and Coria del Río near Seville, Andalusia. With the ceremonial pile-driving completed in early July, construction is officially in motion, and commissioning is expected by 2026. The project features four adjacent solar farms, Granville, Killington, Plumlee, and Rickwood, each contributing 50 MWp and totaling approximately 326,000 photovoltaic panels across 300 hectares.
Renewable Energy & Biodiversity, Hand in Hand
Importantly, Plenitude isn’t just building capacity, it’s pushing sustainable construction forward. The project will test green steel structures, made from fully recycled materials and manufactured in Spain with zero carbon emissions. Additionally, the park design includes vegetation barriers, wildlife habitat islands, and an equal area set aside for sustainable farming. This approach aims to restore steppe bird habitats and foster ecological diversity alongside clean power.

Expanding Plenitude’s Andalusian Portfolio
Entrenúcleos adds to a growing Plenitude footprint in Andalusia, joining the 230 MW Guillena and 150 MW Caparacena solar facilities already in development. With these combined, the company now has nearly 580 MW under construction in the region, and more than 1,300 MW of wind and solar capacity nationwide support a pipeline exceeding 2 GW. According to Mariangiola Mollicone, head of Renewables in Western Europe, Entrenúcleos is a key milestone in achieving Plenitude’s long-term expansion plans and reinforcing its Andalusian commitment.
Driving Spain’s Energy Transition
Once online, Entrenúcleos will generate over 435 GWh of clean electricity annually, enough to power tens of thousands of households, and significantly reduce carbon emissions in southern Spain. Furthermore, the facility will connect to the national electricity grid via a shared Entrenúcleos SET substation, linked to the Red Eléctrica Española network. As Plenitude moves toward its goal of 10 GW of renewables and 11 million customers by 2028, this project highlights how clean energy deployment, biodiversity protection, and regional growth can go hand in hand.
