The Engineering Details That Decide Energy Storage Reliability
A second fire at the Moss Landing Power Plant in California ignited approximately 1,200 battery modules that had not been de-energized following structural damage from a previous incident. This event highlights the critical importance of engineering details and safety protocols for maintaining the long-term reliability
Storage-first models and VPP integration define post-ITC solar market
Industry data shows residential solar installations fell 19% while storage deployments held steady, driving the national battery attachment rate to 49%. This shift highlights how VPP integration and storage-first models are becoming essential for installer viability as export compensation declines.
Batteries Can Reduce Curtailment by Up to 50% and Change the Profitability of Renewable Power Plants
ONS estimates that battery energy storage systems can reduce mandatory curtailment of wind and solar generation in Brazil by 40% to 50%. This analysis is relevant as curtailment losses reached 6.5 billion reais in 2025, highlighting the operational impact of storage on grid stability and asset performance.
Italy authorizes nearly 7 GW of battery storage
Italy's MASE authorized 722.5 MW of new BESS projects on Oct. 30, bringing October's total to 3.7 GW. This surge in approvals highlights the rapid scaling of grid-scale storage capacity in the Italian market.
CATL Secures 24 GWh Order in Australia, Delivers First GWh-Scale 8-Hour Energy Storage System
CATL delivered its first 5.64 MWh EnerQB system to Quinbrook for the Stanwell plant in Queensland, marking the first GWh-scale deployment of its 8-hour storage.
