ACCIONA Connects Renewable Energy Storage Plant Using Recycled Batteries

  • The project will analyze the performance of 130kWh of recycled electric vehicle batteries at an experimental photovoltaic park in Tudela.

ACCIONA has connected Spain’s first renewable storage plant using recycled batteries to the grid, at the company’s experimental photovoltaic park in Tudela (Navarre). The set of four second-life batteries, with a combined capacity of 130kWh, will store the energy obtained from the 1.2MWp plant to later inject it into the grid and analyse its performance and behaviour. The innovation project concludes with a comparative analysis to verify the equal performance of recycled batteries against first use batteries.

The plant includes 32kW/32kWh batteries from Nissan vehicles, which will double their useful life as part of the project. ACCIONA will operate the system from its Renewable Energy Control Center (CECOER) with its global energy management platform GEMS, which enables optimized management, real-time monitoring and analysis of parameters. Renewable energy will be certified throughout the process through ACCIONA’s blockchain-based Greenchain® platform.

The storage plant is part of the experimental facilities of Montes del Cierzo in Tudela and is the result of a joint project with startup BeePlanet within ACCIONA’s open innovation program, I’mnovation. BeePlanet, together with ACCIONA, is part of the GERA project, backed by the Government of Navarre, and specializes in energy storage systems reusing lithium-ion batteries from electric vehicles.

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
