Batteries: The game has changed – and it’s not what you think
A single benchmark no longer exists. In some cases, charging speed is what matters; in others, it is energy density, and in still others, cost and scalability. In other words, the battery is ceasing to be a simple component. It is becoming the transversal energy infrastructure of the next industrial cycle. And those who can control not only the technology but also production, integration, and the grid will have an advantage that will be difficult to recover.

Volatility returns: Battery revenues in March 2026
March saw a sharp rebound in battery revenues in Germany. While average price levels increased only moderately, shifting dynamics between solar-driven price troughs and fossil-driven peaks created a more favourable trading environment. Lennard Wilkening, CEO and co-founder of suena energy, analyses what defined the month and why cross-market strategies proved particularly effective.
From patchwork to harmony: The case for aligning standards in energy storage
Improving safety and security does not require lowering standards, but it does require aligning them. This is where an industry-led approach – one that brings together manufacturers, developers, validators and insurers – comes in, writes Ken Stewart, senior manager ESS at Sungrow Europe.
Why system-level fire testing is becoming the new benchmark for grid-scale BESS safety
As utility-scale battery energy storage systems continue to be deployed across Australia’s National Electricity Market, fire risk assessment is rapidly shifting from a compliance exercise to a core project viability consideration. For developers, asset owners, insurance considerations and regulators, the key question is no longer whether systems meet component certification standards, but how complete BESS systems behave under severe real-world conditions.
The return of negative prices: Battery revenues in February 2026
February began with familiar winter stability, but ended with the return of negative prices driven by solar feed-in. As market dynamics started to shift, battery revenues reflected both compression and emerging new opportunities. Lennard Wilkening, CEO and Co-Founder of suena energy, explores what defined the month and what it signals for spring.

It’s high time for an EU Battery Storage Action Plan
Global deployment of battery energy storage systems (BESS) is accelerating at an unprecedented pace – with world installations projected to expand swiftly in the coming years. While the European Union experienced a sluggish growth in BESS deployment in 2024, it is poised for a bounce back in 2025. However, absent bold and decisive policymaking, the EU risks falling considerably short of the scale required to meet its climate and energy targets, writes Antonio Arruebo, market analyst at Solar Power Europe.
From factory to field: How energy storage innovations are responding to Europe’s C&I segment
The growth of the commercial and industrial (C&I) segment in Europe’s energy storage market is driving new investment opportunities. Bonn-based EUPD Research has explored what this growth means for both manufacturers and investors, as well as how manufacturers are addressing the needs of C&I installers and customers.

Why the strategy is key: Lessons from real-world benchmarks
Maximizing value from battery energy storage systems (BESS) isn’t just about having the right hardware – it’s about executing the right strategy. Lennard Wilkening, CEO and co-founder of Germany's suena energy, explores what makes standalone BESS profitable in increasingly competitive and volatile market, and what real-world benchmarks, such as suena’s monthly revenue update, reveal about the role of dynamic multi-market optimization.
Battling battery imbalance
Imbalances – when battery components fail to operate in unison – are a recurring challenge in energy storage projects. Kai-Philipp Kairies, CEO of Accure Battery Intelligence, examines the root causes of imbalances, their effects on operations and return-on-investment, and actionable best practices to mitigate them.
