A wholly owned subsidiary of SMA Solar Technology AG (SMA), Altenso has experienced substantial growth over the last five years in particular to become a leading international system integrator. Altenso is now laying the groundwork for further growth by stepping up its focus on project development.
100 employes from 20 countries
Since its foundation in the summer of 2014, the subsidiary of SMA has established significant milestones as an international solution provider for complex solar hybrid, off-grid and grid-connected battery energy storage systems (BESS) and hydrogen (P2G) applications. Overall, the company has now implemented BESS projects with an output of around 1.5 gigawatts and P2G projects with an output of approx. 1 gigawatt.

The solar and battery-based energy system on the Caribbean island of St. Eustatius is one example of a successful Altenso project. Equipped with SMA solar and battery inverters, the system features innovative functions such as grid forming and black start capabilities and provides the island with an electricity supply sourced entirely from renewable energies during the day. Other success stories include a hydrogen application with an electrolyzer capacity of 20 megawatts (MW) in Puertollano, Spain, which supplies a fertilizer plant. The system, which produces up to 3,000 tons of green hydrogen annually, went into operation in 2022 and is supplied by a 100-MW PV farm.
Hydrogen project in Namibia
Altenso has a unique task on the agenda for next year consisting of a solar-based hydrogen production project in Namibia with an additional battery storage system. In addition to carrying out the system integration for the BESS, the company will also be installing the rectifier system for hydrogen production. A completely new logic has been developed for the energy management system (EMS) used in this project.
