Beyond the cell: The evolution of battery costs
For years, the battery energy storage (BESS) story has followed a familiar script: costs fall, deployment accelerates, economics improve. Yet with rising costs for battery cells, the opposite might be expected. Paola Perez Peña, senior principal analyst at S&P Global Energy, examines why the latest jump in lithium prices has only had limited impacts on overall BESS costs so far.
Installed BESS capacity in Spain grew by 589% since 2025 blackout
Some of the consequences of the blackout include a 589% increase in installed BESS capacity in Spain between April 2025 and April 2026, the introduction of renewable participation in voltage control, a greater role for gas in the generation mix, and continued progress on interconnections.

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.
Financial sponsor capital increasingly complements utility investment in battery storage
With BESS now an investable asset class, infrastructure funds are acquiring developer platforms and financing large portfolios to accelerate deployment across Europe. Carlos Candil and Carlo de Haas of Lincoln International are dissecting the trend.
Steady but not static: Battery revenues in January 2026
January brought a largely balanced power system to Germany, with firm winter demand, scarce negative prices, and contained volatility. Yet beneath stable price levels, revenue opportunities shifted across wholesale and balancing markets. Lennard Wilkening, CEO and Co-Founder of suena energy, breaks down how battery optimization performed in this compressed yet still actionable market environment.
