Energy infrastructure Construction

Sando Conservación y Energía has a specialized business line focused on the construction and maintenance of electrical installations and renewable energy plants, such as industrial solar power and electrical cogeneration, as well as the implementation of energy efficiency solutions.

The company operates through four main lines of action focused on resilient projects: EPC (Engineering, Procurement and Construction), renewable gases, self-consumption and energy efficiency, and the deployment of the plug-in electric vehicle (PEV)

The Engineering, Procurement and Construction (EPC) line covers renewable energy projects in photovoltaics, wind power, lithium battery hybridisation, Li, BESS, reversible hydroelectric power plants, reversible hydroelectric storage, pump as turbine (PAT), pressurised grid energy utilisation. Over more than 15 years of specialized energy services, Sando Conservación y Energía has built transformer stations of up to 6,000 kVA, constructed and commissioned substations of up to 66/20 kV and 30 MVA, and installed more than 100 km of high-voltage lines up to 220 kV and more than 40 km of medium-voltage lines up to 30 kV.

The projects carried out in the area of renewable gases comprise the so-called power-to-gas projects and those that integrate the circular economy into the processes. These projects include pyrolysis, gasification and production techniques in green hydrogen (H2) electrolysers, transformation to green ammonia (NH3), and carbon dioxide (CO2) capture for the production of synthesis gas, methanol, biofuel, SAF, syngas, biochar and its use in fuel cells. Waste recovery processes are done through anaerobic digestion in ecoplants and biofactories for biogas production, upgrading to biomethane.

Through its self-consumption and energy efficiency business line, Sando Conservación y Energía provides clients with solutions to improve sustainability, including energy retrofitting, External Thermal Insulation Composite Systems (ETICS), heating electrification, greenhouse gas emissions reduction, geothermal energy, and aerothermal energy systems. In recent years, solutions have included the construction and development of 0.5MW of fixed PV in La Rinconada (Seville) with grid feed-in (from greeenfield to ready to ready-to-build (RTB)and the construction in public-private partnerships (PPP) of photovoltaic self-consumption facilities with a total of 9.5 MW; and a 0.5 MW floating PV plant for an irrigation community.

Finally, the company has solutions that enable the deployment of plug-in electric vehicles (CEPV), such as installing electric chargers, which help reduce CO2 emissions and install chargers. A través de Power Purchase Agreement (PPA) con distribuidoras y comercializadoras eléctricas, Sando Conservación y Energía ha realizado la instalación, operación y mantenimiento de más de 30 puntos de recarga de vehículo eléctrico conectable con suministro de energía eléctrica 100% renovable.

In addition, Sando Conservación y Energía develops R&D&I projects aimed at designing sustainable energy solutions. Notable among these are the VICTORIA project, which led to the development of Spain’s first dynamic wireless electric charging lane, and the GENESI project, focused on the use of non-polluting electrically powered machinery for maintenance activities in urban environments.

Together with the University of Malaga and Sando Agua, it is investigating the EMBIO project to analyse the opportunities for producing renewable hydrogen from Waste Water Treatment Plants (WWTP) to convert these plants into biofactories that generate renewable energy for other sectors. This project contributes to both energy efficiency and the Circular Economy, as it would make it possible to use waste from other activities.
