The Munich-based company Stabl Energy is supplying battery storage systems to the Austrian hydroelectric power plant operator Elektrowerk Schröder.

A first for Stabl Energy: According to the company, the Munich-based battery storage manufacturer is implementing its first project outside of Germany. The customer is the Austrian hydroelectric power plant operator Elektrowerk Schröder. The family-owned business in Styria supplies approximately 2,400 households. Seven battery storage systems are intended to make the power supply more flexible in the future.

Stabl Energy plans to install four of the battery storage systems at the power plant operator’s central control center by the end of August. Three more are planned for power plant sites. The startup uses reused battery modules as well as unused batteries from production surpluses or other surplus stock for its storage systems. The company itself refers to these as “second-chance and zero-life batteries.”

The systems use “modular multilevel inverter technology,” which allows battery modules in different states of charge to be combined within a single storage system, according to the battery manufacturer. Based on this technology, the storage systems are expected to achieve an efficiency of 94.6 percent. The storage systems for the Austrian utility are expected to have a total capacity of 13,000 kWh.

Elektrowerk Schröder generates electricity at three of its own hydroelectric power plants. In addition, it receives electricity from seven privately owned hydroelectric power plants and several private photovoltaic systems. This electricity supplies residential and commercial customers as well as public institutions in the Murau district. The battery storage systems are intended to increase self-consumption and relieve the strain on the power grid. The project aims to operate within a smart grid that integrates generation, storage, and consumption.

“The market offers great potential for flexible storage solutions that efficiently integrate renewable energy while strengthening the security of supply,” says Stabl’s Head of Sales, Rene Bisplinghoff, commenting on the move into Austria. And that’s not where it will end. “This project marks the start of our expansion in German-speaking countries, before we set our sights on other European markets.”

Stabl Energy was founded in 2019. The company currently has more than 80 employees. The battery storage manufacturer estimates the capital inflow from private and public investors at just over 20 million euros. In its 2024 financial statements, the company reported equity of 7.8 million euros. The bottom line showed a net loss for the year of 4.7 million euros (2023: 3.2 million euros).
