Plenitude, the renewable energy arm of Eni, is progressing construction on its 200 MW Entrenúcleos solar park in Dos Hermanas and Coria del Río in the province of Seville, Andalusia, expected to be commissioned this year. The utility-scale photovoltaic (PV) development with approximately 326,000 PV modules will consist of four 50 MWp solar plants – Granville, Killington, Plumlee and Rickwood – spread across more than 300 hectares and is expected to generate over 435 GWh of renewable electricity annually. This is enough to support tens of thousands of households while significantly reducing carbon emissions in the region alongside other renewable energy projects like the Andalusia Green Hydrogen Valley which recently took a €1 billion FID on its first 300 MW phase. Construction at Plenitude’s Entrenúcleos Solar Park began with a groundbreaking event attended by regional energy officials and municipal representatives in 2025.

Project Factsheet

Developer: Plenitude, Eni’s renewable energy arm in Spain

Location: Between Dos Hermanas and Coria del Río, Seville, Andalusia

Capacity & Layout: 200 MW total, split into four 50 MWp units: Granville, Killington, Plumlee, and Rickwood

Covers over 300 hectares and features 326,000 solar panels

Energy Output: Expected annual production of 435 GWh, enough to power thousands of homes

Timeline: Construction began in July 2025, with commercial operation targeted for 2026

Grid Connection: Connected via a shared Entrenúcleos SET substation, linked to Spain’s national grid though REE

Sustainability Features: Built using green steel, a fully recycled, zero-carbon material

Regional Significance: Project sits alongside Plenitude’s commits to Guillena (230 MW) and Caparacena (150 MW), bringing the total Andalusian pipeline to 580 MW

National Strategy: Adds to Spain’s installed renewable mix of 1,300 MW of solar and wind, feeding into a wider 2 GW project pipeline

Project Team Building Plenitude’s 200 MW Entrenúcleos Solar Park in Spain

Plenitude S.p.A. Società Benefit – Lead developer and project owner. Plenitude is managing construction, permitting, grid connection planning and integration into Spain’s renewable energy system.

Solarig – Engineering, Procurement & Construction (EPC) partner executing civil works and solar plant installation for Entrenúcleos as part of an established EPC portfolio in Andalusia.

Regional Government of Andalusia – Permitting and stakeholder facilitator. Also had representation at the project’s groundbreaking; supports renewable deployment in the province through regulatory oversight and energy planning.

Dos Hermanas Town Council (Ayuntamiento de Dos Hermanas) – Municipal stakeholder engaged in site planning, community liaison and local coordination during construction.

Red Eléctrica de España (REE) – Grid operator providing high-voltage transmission connection via the SET Entrenúcleos substation and national network linkage.

Entrenúcleos Solar Park: Spain’s 200 MW Renewable Energy Milestone

Reported July 4, 2025 – 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. It will join 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. Entrenúcleos solar park also supports a growing renewables 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.
