BESS optimisation company Enspired has recently announced expansion into Greece, Spain and Poland, but how will it approach operating across markets and what benefits will it bring? We hear from its CEO.
Earlier this year, the Austria-headquartered company released data on its own financial performance in its main market of Germany, while the last three months have seen it expand beyond its home markets to Spain, Greece and Poland. Battery energy storage system (BESS) optimisers tend to operate mainly in one country, so the moves are noteworthy.

In May, it formed a strategic alliance with with Greece’s largest renewables and flexible load aggregator Optimus Energy to offer offer optimisation as a service to storage asset owners. The initial portfolio the two will work on totals 270MW of projects, including projects from owners GEK Terna Group and Heron Energy.
In June, Enspired repeated this move in Spain, with the country’s ninth largest energy trader Nexus Energia to incorporate its technology into Nexus’ asset optimisation offering in the Spanish market. The partnership will cover both standalone and renewables-hybridised projects.
Enspired has now also announced a deal with Ekovoltis, the largest seller of electricity from renewable sources in Poland and the country’s first Balancing Utility Provider (DUB). The pair will bring BESS optimisation services to Poland, combining Ekovoltis existing market presence and expertise with Enspired’s automated optimisation technology.
Energy-Storage.news asked Enspired CEO Jürgen Mayerhofer for more information about its approach to new markets, what benefits being internationalised would bring, and to what extent assets can be co-optimised across European borders, for this short Q&A.
Energy-Storage.news: Can you say a little about each new market and the general commercialisation model, Enspired’s approach to this, the broader revenue stack and how these are evolving?
Jürgen Mayerhofer, Enspired CEO: With our in-house optimisation platform, we can seamlessly adapt to current and future market specifics, integrating diverse revenue streams such as imbalance and capacity markets. Our focus is on maximising our clients’ revenues through continuous innovation. We have already demonstrated this approach in practice; for example, by becoming the first optimiser in Germany to fully integrate all available revenue streams for BESS.
We recently announced our expansion into Spain and Poland. Our commercial model is more or less the same for all countries. We aim to offer all types of offtake structures, from fully merchant to tolling and everything in between. From a technological point of view, we seek the best local partners to integrate our optimisation service via a joint offering. Having said that, finding a partner with matching DNA and a strong focus on innovation and technology is not as easy as it seems.
Let’s start with Spain. It’s a developed market that actively supports the buildout of BESS with dedicated initiatives. The government announced €700 million (US$818.1 million) in subsidies, there is a public target of 22.5GW by 2030, solar penetration is high, and the recent blackout brought to light valuable opportunities for BESS. Our partner Nexus Energía is the leading player in providing route-to-market services for renewable generation. With more than 16,000 assets under management, access to all revenue streams, and a highly innovative leadership team – this is the ideal setup.
Through the collaboration, we are making full-range optimisation services available to local asset owners who want to maximise their revenues. We facilitate this with a mature cross-market optimisation strategy and sophisticated algorithms that have been proven to deliver superior commercial results.
We are the first and only optimiser with published portfolio performance, an independently confirmed metric showing real, verifiable revenues rather than the artificially inflatable approximations that are the norm in the industry. Nexus Energía has the necessary infrastructure to integrate our service, including market access and ancillary service expertise with a strong track record in RES optimisation. Together, we are ensuring batteries can profitably contribute to local grid stability long-term.
The emerging Polish market recently connected to PICASSO (Platform for the International Coordination of Automated Frequency Restoration and Stable System Operation, an initiative to synchronise delivery of the aFRR ancillary service – Editor) and is currently one of the most promising in all of Europe.
The 2024 balancing reforms created new potential for BESS to capture value. Through our partnership with Ekovoltis, one of the largest industrial groups in Poland, we have access to the necessary technical infrastructure and a considerable pipeline of storage projects. Ekovoltis is the first Polish trading company with a complete set of key systems in place to support participation in regulatory system services (RUS), which ensures fast market access and reliability for customers. Together, we are making the most advanced solution for battery monetisation available to local asset owners so they can optimise their revenues by participating strategically in all lucrative markets, from wholesale to balancing services.
What kind of benefits does being internationally diversified have for an optimiser?
International expansion comes with international expertise. There is a duality in the knowledge and experience we gain from existing and new markets: When we enter a new market, learnings from other countries allow us to fine-tune the optimisation in a more precise and targeted manner from day one. At the same time, new markets bring fresh insights that can be useful in existing markets.
Our setup allows us to adapt to new market regulations quickly and seamlessly. And once we have, we can leverage economies of scale, especially in continental Europe, where wholesale markets and ancillary services have highly harmonised structures. Full exposure to only one market is not a sustainable strategy, and our portfolio grew exponentially because we entered new markets.
Being internationally diversified sharpens our strategic position: It enables us to detect emerging trends and regulatory shifts earlier, benchmark best practices globally, and invest more confidently in innovative solutions. This broader perspective helps us anticipate market evolutions rather than merely reacting to them. Diversification ultimately creates valuable opportunities, reduces risk, and builds resilience to disadvantageous changes in local market policies. After all, in such a dynamic industry, staying ahead isn’t just about adapting — it’s about shaping the future.
To what extent can BESS be co-optimised across European borders, taking into account the relationships between interconnected energy markets & pan-European procurement of ancillary services?
The batteries in our portfolio are optimised across all relevant markets. This includes participation in the European cross-border wholesale markets, in aFRR energy bidding as part of the PICASSO framework, and in the FCR Cooperation. The optimisation is based on pan-European data and considers influences from all countries.
However, a single battery can only be optimised in the TSO zone of its grid connection, meaning its capacity cannot be segmented and allocated to a specific geographical market. In terms of countries, we don’t decide where the asset’s energy ultimately goes. It flows where it’s needed within the interconnected market, but we don’t formally sell from country A to country B.
