DateStageInvestorsRaisedDeal Summary
Oct 2025Undisclosed stageAPG Asset Management (lead)$346MReturn is an energy storage solutions provider developing grid-scale battery storage platforms across Europe to integrate renewables, manage energy flows, and alleviate grid congestion. The company operates independently without trading energy itself and is active in the Netherlands, Germany, Belgium, and Spain, with 70 MW of operational storage capacity in the Netherlands and 450 MW under construction. Return is building the largest battery in the Netherlands at 350 MW capacity and rolling out a 'virtual battery' concept for energy companies. It aims to develop a pan-European storage network of around 5 GW by 2030 and previously acquired a majority stake in J&P Batterie Projekte via a €50 million investment to expand in Germany. On October 16, 2025, APG Asset Management, on behalf of pension fund ABP, announced a €300 million (~$348-350 million) growth equity investment in Return for a minority stake. The transaction, advised by multiple firms including Santander CIB for Return and Nomura for APG, was signed in October 2025 and is pending regulatory approval to close by year-end. This capital supports scaling Return's battery storage platform by converting its de-risked development pipeline—secured with grid access and permits—into operational projects without delay. The partnership establishes a long-term strategic alliance to deliver reliable, flexible energy solutions for portfolio balancing and grid resilience. APG views Return as a compelling infrastructure investment aligning with net-zero goals, emphasizing its integrated platform, execution speed, and market positioning. Prior to this round, Return had invested a similar amount in core operations, positioning the funding to accelerate European expansion amid growing energy transition demands from electrification and renewables intermittency. The investment fits APG's strategy in clean infrastructure for stable returns, with ABP managing €590 billion in assets. It reflects broader sector trends, as Mercom reported $1.7 billion in VC funding for energy storage in 1H and Q2 2025 across 36 deals, down 29% year-over-year, with downstream companies leading.
