Microgrid

The United States added 18.9 GW of energy storage capacity in 2025, a 52% increase year on year, according to Wood Mackenzie.

In an interview with pv magazine, Jay Johnson, the CTO of US-based cybersecurity firm DERSec, explains that PV systems face cybersecurity risks that extend far beyond inverters, as demonstrated by a December attack on Polish solar plants where wiper malware targeted substation equipment rather than the inverters themselves. Vulnerabilities often lie in backhaul communication channels like APIs and mobile apps, making layered defenses, network segmentation, and vigilant monitoring essential to safeguard distributed energy resources.

The “Battery Atlas 2026” report shows consolidation in Europe’s battery market. More than 2,000 GWh of cell production capacity was announced in 2023, but the realistic forecast for early 2026 is around 1,190 GWh, including approximately 673 GWh led by Asian companies.

A systems approach is essential for smart energy standardization, ensuring interoperability, avoiding overlaps, and addressing complex interactions across the grid, appliances, and infrastructures. The IEC System Committee for Smart Energy (SyC SE) applies system-level thinking, using tools like reference architectures and roadmaps to coordinate standards, support innovation, and tackle emerging areas such as EV integration, digital twins, and zero-emission technologies.

The South Korean government has announced plans to invest KRW 321 billion ($222.6 million) in 2026 to upgrade regional distribution networks, deploy 85 energy storage systems, and expand solar integration while piloting microgrids and market reforms.

Helmholtz-Zentrum Dresden-Rossendorf (HZDR) researchers have used operando X-ray imaging to reveal why sodium-zinc molten-salt batteries, operating at around 600 C and promising for stationary energy storage due to low-cost, abundant materials, experience persistent capacity loss.

The Chinese company said its modular system supports up to 64 kWh of storage, multiple PV inputs, and 0 ms backup switching for uninterrupted operation.

Sungrow says it plans to invest €230 million ($274 million) in its first European factory in Wałbrzych, Poland, to produce inverters and battery energy storage systems (BESS).

Rystad Energy says it expects global battery energy storage system (BESS) additions to exceed 130 GW/350 GWh in 2026, led by China, the United States, the United Kingdom, Australia, and Germany.

The European Union added 27.1 GWh of battery energy storage capacity in 2025, with utility-scale systems accounting for the majority of new installations as residential storage declined amid lower electricity prices and reduced support schemes, according to a new report from SolarPower Europe.
