Battery storage systems can be set up in several different ways to help electricity networks stay stable as more wind and solar power is used. According to the authors of the newly released report, these various configurations allow the grid to manage fluctuating energy production, provide backup power, and reduce costs for consumers.
“Colocated BESS projects primarily smooth renewable output, support renewable integration, and reduce curtailment. Standalone grid-connected BESS projects provide frequency regulation, capacity, and energy arbitrage.”
In simpler terms, putting batteries directly at wind or solar farms helps ensure a steady flow of electricity even when the weather changes, preventing clean energy from going to waste. Other battery systems that sit on their own help keep the entire network’s electrical rhythm stable or act as a massive backup reserve that can be used when demand is high and prices are most expensive.
The report “Energy Storage Signals Shift to Renewable Grids” was published in March 2026 by the Global Energy Monitor. Prepared by lead author Ye Huang, the briefing analyzes the rapid global expansion of battery storage systems and their essential role in integrating variable wind and solar power into modern electricity grids.
