Enspired raises ‘over €40 million’ to expand battery optimization beyond Europe

Enspired, a Vienna-based optimizer for battery energy storage systems (BESS), has extended its Series B round to exceed €40 million as it looks to grow its presence outside Europe. The funding brings in Future Energy Ventures as a new investor, joining returning backers Zouk Capital, EnBW New Ventures, Banpu Next, Push VC, and 360 Capital.

The company, which offers AI-powered flexibility optimization for energy storage assets, says the additional capital will accelerate its global expansion and the rollout of new use cases for its trading and optimization platform.

“Within the last 12 months, we entered six new markets and crossed the magical 1GW mark of BESS under management. We proved our undisputed leadership in commercial optimization by publishing our actual, certified revenues. We are at our greatest peak, and we won’t stop here,” said Enspired CEO and co-founder Jürgen Mayerhofer.

The exact funding amount was not revealed, and Enspired last secured funding in May 2024, when it raised €25.5 million in Series B funding, then led by Zouk Capital, a British private equity and infrastructure fund manager.

Enspired’s Series A funding round closed in 2021 with USD $8.7 million.

At the time of the Series A, Mario Schmoltzi was listed as a co-founder and chief commercial officer, but has ceased in that role without public comment. He remains listed as a co-owner of Enspired, and is working in a start-up focused on real estate.

Expansion to Japan

A key part of that international growth is its new partnership with Banpu Next, a Net Zero Solutions provider in the Asia-Pacific region. Banpu Next is now deploying Enspired’s optimization technology in Japan, where the partners will develop AI-driven energy solutions for the local power market. The collaboration is expected to bolster the storage and trading business for the company. (Banpu Next was also an investor in the fundraising round.)

“Banpu Next is excited to be the first partner outside of Europe to take advantage of Enspired’s superior optimization approach. With their expertise and advanced AI technologies, we are collaborating on the development of innovative energy solutions for the Japanese power market,” said Smittipon Srethapramote, CEO of Banpu Next, which is headquarteed in Thailand.

The funding follows a period of rapid expansion for enspired, which now operates across several European markets and is preparing to enter the United States and parts of Asia, only announcing a few months ago that it was moving into Spain and Poland with partners.

Enspired’s trading platform is designed to optimize batteries and other flexible assets across wholesale, reserve, and ancillary service markets, providing automated revenue maximization for storage operators.

Enspired’s positioning looks to be one of the few European firms with the scale and technical reach to compete globally in commercial BESS optimization.
