Your dedicated development team in Spain.
Storium specialises in the hybridisation of Utility Scale BESS with renewable plants, as well as in the permitting and expropriation processes for high and medium voltage power lines — supporting developers, utilities and investors from project conception through to Ready To Build.
A Spanish team built for large-scale energy development.
Storium is a Spanish company specialising in the development of large-scale energy projects. The team is formed by professionals with more than ten years of experience developing renewable projects in Spain, with particular knowledge of the Andalusian market and extensive experience working with public administrations and regulatory bodies.
Our core specialisation is the hybridisation of Utility Scale BESS with renewable plants, together with the expropriation processes required to secure the power line easements that connect them to the grid — a combination of technical, legal and administrative expertise where our track record speaks for itself.
Your development department in Spain — without building one.
Storium provides dedicated teams that work exclusively for each client. These teams integrate directly into the promoter's existing structure — using its internal procedures, corporate tools, document systems and communication channels.
The result is real development capacity, delivered without the time or cost of standing up a permanent internal structure.
