SAMPOL, as part of its firm commitment to decarbonisation and energy independence in the Balearic Islands, has successfully completed the Son Magraner project in the municipality of Palma. This facility represents a technological milestone by combining photovoltaic power generation with state-of-the-art energy storage systems, directly contributing to the climate objectives of Spain and the European Union.
A decisive boost thanks to NextGenerationEU Funds
The implementation of this project has been made possible thanks to financial support from the European Union through the Recovery and Resilience Facility (NextGenerationEU). Within the framework of Spain’s Recovery, Transformation and Resilience Plan (PRTR), managed by IDAE, the Son Magraner project has received public funding that strengthens the viability of critical infrastructure for the regional energy transition.
The financial details of the project are as follows:
- Total investment: €6,467,883
- Public funding awarded: €2,629,035.63
Innovation and Technology: Power Generation and Storage (BESS)
The Son Magraner project is not merely a power generation plant, but an intelligent energy system designed to optimise the management of Mallorca’s electricity grid. The facility consists of two fully integrated technological components:
- 3.7 MW Photovoltaic Plant: Comprising a 4.56 MWp solar array with more than 6,500 monocrystalline panels installed on fixed structures at an optimal tilt angle.
- Battery Energy Storage System (BESS): A pioneering solution with a nominal power output of 2,090 kVA and a storage capacity of 4,180 kWh. This high-density lithium battery-based system enables surplus renewable energy to be stored and fed into the grid during periods of peak demand, thereby ensuring the stability of the island’s electricity system.
Sustainability and Respect for Local Heritage
Beyond its clean energy production (estimated at 7,941 MWh annually), Son Magraner stands out for its exemplary environmental integration and cultural heritage preservation. During the construction phase, SAMPOL implemented rigorous measures to protect local wildlife and ensured the preservation of the Séquia de la Font de la Vila Site of Cultural Interest (BIC), a historic infrastructure that has been fully respected in the plant’s design.
Through this project, SAMPOL and the European Union demonstrate that public-private collaboration is an essential driving force in achieving an emissions-free future for our islands.
