Floating Photovoltaics
A lightweight photovoltaic pilot project is installing 16 kWp on the tensioned cover of an irrigation pond in Almería. This solution utilizes flexible and low-weight modules, secured to an existing cable mesh, thereby avoiding civil works, foundations, and conventional metal structures. The energy generated is allocated for the self-consumption of the adjacent greenhouse, reducing costs and carbon footprint for ventilation, irrigation, and lighting needs. Furthermore, it leverages underutilized surfaces and contributes to decreasing the evaporation of stored water, which is crucial in areas experiencing water stress. The pilot incorporates advanced sensing technology to monitor real-time production and environmental conditions, evaluate the water’s cooling effect on performance, and analyze its technical and economic viability. The findings will serve to scale and replicate this solution across other agricultural ponds.

GIRA Wind
Together with Ruralia, Posteléctrica and Invenergy Services, we manage wind farm dismantling processes and recover dismantled turbines. The main aim of the initiative is to inspect and overhaul turbines that have been in service for many years. This covers the turbine as a whole and all the individual parts. In addition, parts that are not fit for further use but can be given a second life as raw materials are processed.
The project is based on an experimental plant in Almazán (Soria), where a number of technologies and processing lines will be tested. Subsequently, plants will be set up in different locations so that they can build a close relationship with the surrounding area and those who work there.
