Finland proposes priority system for grid connections
Finland’s government is proposing a priority system for electricity network connections in areas of scarce grid capacity in a bid to incentivise large electricity consumers and standalone storage systems to locate in areas where the grid is less congested.
French startup repurposes EV batteries for solar energy storage at 30% discount
Battwoo is repurposing electric vehicle batteries for stationary energy storage, targeting solar self-consumption and other commercial and industrial applications. The company says its refurbished systems can cost around 30% less than new batteries while extending battery service life by several decades.

Spain launches capacity market via auctions, with key rules that support energy storage
Spain is introducing a new mechanism to remunerate generation, battery storage and demand for providing firm capacity and flexibility, while increasing planned electricity grid investment through 2030 to more than €17 billion ($19.5 billion).
Battery diagnostics expert urges earlier fire detection for grid-scale BESS
A battery diagnostics specialist says grid-scale battery energy storage system (BESS) safety should focus more on detecting early warning signs in operational data than adding more sensors or fire suppression equipment after high-profile incidents.

Enervis Battery Storage Index – German BESS revenues stay high in June
German battery storage revenues held at a high level in June, rising to around €18,000 ($20,500)/MW as strong solar output and heatwave-driven price spikes boosted spot and ancillary market earnings, according to enervis energy advisors' monthly Battery Storage Index.
India’s battery recycling industry must move beyond black mass
India is expanding battery recycling capacity, but most recyclers stop at producing black mass, leaving higher-value refining and critical mineral recovery largely to overseas processors, says Manikumar Uppala, chief of industrial engineering at Metastable Materials.
Heatwave, weak wind push battery revenues higher in June
June brought another month of scarce but favorable market conditions for battery trading, as high temperatures, weak wind generation and a prolonged heatwave continued to shape electricity markets and influence price dynamics across wholesale and ancillary service markets. Lennard Wilkening, CEO of Suena Energy, explains what drove the market and why dynamic multi-market optimization remains key to capturing value.
India’s battery storage market faces volatility, seeks new growth
India’s severe heatwaves in April and May, followed by a delayed southwest monsoon, have highlighted the growing challenge of balancing one of the world’s fastest-growing renewable power systems. As solar capacity continues to expand and grid constraints become more apparent, India’s battery energy storage sector is at a pivotal stage.
A different kind of volatility: Battery revenues remain strong in May 2026
April was defined by solar-driven oversupply and recurring negative prices. May told a different story. Wind generation dropped sharply, wholesale prices climbed, and ancillary services gained importance as the system searched for flexibility. Yet battery revenues barely moved. Lennard Wilkening, CEO of suena energy, explains why this is another reminder that successful battery trading depends less on any single market regime than on the ability to adapt across them.
