Private 660 MWh solar-storage project closes financing in South Africa
Naos‑1 is described as South Africa’s biggest private utility‑scale solar and battery storage project, designed to wheel power to industrial customers.
World’s first 628 Ah grid-scale battery enters operation
EVE Energy says a 200 MW/400 MWh battery energy storage project in China has entered operation, which it describes as the world’s first utility-scale deployment of 628 Ah lithium iron phosphate (LFP) cells.
Hungary launches grants for residential battery storage
Hungary has opened applications for a program offering up to HUF 2.5 million ($7,820) per household to support residential battery storage, prioritizing grid-exporting solar users and small rural settlements.
Energy Vault secures 1.5 GWh sodium-ion supply for AI
Switzerland-based Energy Vault has secured an initial 1.5 GWh of sodium-ion battery supply from Peak Energy to develop integrated storage systems for artificial intelligence-focused data centers.
Global BESS capacity tops 250 GW, overtaking pumped hydro for first time
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.
100 MW Hertz 1 battery enters operation after Estonia–Finland grid incident
The 100 MW/200 MWh battery energy storage project in Kiisa began operation on Feb. 3 as scheduled – just two weeks after a testing fault at the facility caused the most significant disturbance to the regional power grid since Estonia’s desynchronization from the Russian electricity system.
Europe contracts nearly 24 GWh of BESS under flexibility purchase agreements in 2025
With conventional renewable PPA momentum slowing, Europe’s flexibility market soared in 2025, driven by a surge in fixed-offtake agreements and BESS optimization structures. At the same time, co-located storage gained unprecedented traction, signaling a shift toward more integrated and flexible energy solutions.
Testing fault at 100 MW battery disrupts Estonia-Finland power link
During testing at Estonia’s 100 MW Kiisa battery park, both EstLink 1 and EstLink 2 tripped, triggering the most severe disturbance to the regional power grid since desynchronization from the Russian electricity system. As a result, nearly 1 GW of capacity was lost within seconds. The park’s owner has since publicly pointed to the battery manufacturer.
Iberdrola commissions Spain’s largest utility-scale battery systems
Iberdrola has commissioned Spain’s first utility-scale batteries at Alarcón, while Spain’s battery pipeline grows as major utilities develop new projects amid negative electricity prices.
EU installs 27.1 GWh of battery storage in 2025 as utility scale leads
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.
