The Mobility House Energy has reached a major milestone with the onboarding of four new battery storage systems this month: what began in 2016 with 12 MW from 1,000 used smart vehicle batteries has now exceeded the 1 GW mark across 47 projects in four countries. At a time when intelligent battery storage optimization is becoming a central building block of Europe’s energy transition, this step demonstrates that The Mobility House Energy’s technology works at scale.
Co-location: Making solar power predictable and economically viable
Photovoltaics and battery storage are increasingly coming together out of economic necessity – driven by more frequent negative electricity prices during sunny midday hours and declining feed-in tariffs. Battery storage shifts low-cost solar power from midday surplus periods into the more valuable evening hours, prevents curtailment and reduces redispatch and grid expansion costs. At the same time, it smooths volatility in the system – the very fluctuations that would otherwise bring expensive gas-fired power plants into the market and, through the merit order, drive up electricity prices for everyone.
In this way, PV becomes a key pillar of a CO₂-free, decentralized, resilient and affordable energy supply. The Mobility House Energy has already put this model into practice in almost 30 co-location projects, building extensive experience in the design, marketing and operation of such systems.
Technology and market expertise since 2016
The fact that The Mobility House Energy is now managing and optimizing storage portfolios of this scale is the result of many years of hands-on project experience: from the first large-scale battery storage system with Mercedes-Benz, to second-life batteries in the Johan Cruijff ArenA in Amsterdam and the multi-use storage system on Berlin’s EUREF Campus, through to the near-weekly commissioning of new storage projects in additional countries. Step by step, these projects have created the company’s technology and optimization expertise.
The key to this growth is The Mobility House Energy’s aggregation and trading platform, which has been continuously developed since 2016. Its FlexibilityAggregator and FlexibilityTrader technologies pool decentralized battery capacities and optimize their use in real time across multiple markets, including day-ahead, intraday, FCR, mFRR and aFRR.
Especially for large-scale battery storage systems, economic success is not determined by technical availability alone, but above all by the trading strategy. Battery storage systems can absorb or feed back electricity within a very short time – but their value is only created when this flexibility is deployed in the right market at the right moment. The Mobility House Energy’s FlexibilityTrader automates this decision-making process and optimizes storage assets across energy markets, based on price developments, technical availability and market opportunities.
In practice, this means that instead of aligning an asset with a single market, the platform continuously analyzes all available revenue streams and decides in real time where the battery’s flexibility is most valuable at that moment. This multi-market strategy maximizes revenues per unit of installed capacity – making battery storage significantly more attractive for investors and operators than traditional feed-in tariff models.
"The 1 GW mark is much more than a number for us. It demonstrates that, thanks to the dedication of our team, outstanding partners and innovative technology, the new energy world is becoming reality. With stationary storage, we can already show today what we still need to scale with vehicle batteries and V2G"
