Evidence preview
- pv magazine International — Australia’s National Electricity Market adds 1.8 GW in Q4 2025pv-magazine.com
- Energy-Storage.news — At nearly 200GWh, China’s new energy storage deployment rate hit recenergy-storage.news
Overview
Grid-scale batteries continued to scale rapidly across major power markets at the end of 2025. In Australia’s National Electricity Market, new solar and battery projects moved through commissioning and connection milestones, while China reported a sharp year-on-year rise in cumulative installed capacity of “new energy storage” technologies including lithium-ion.

Why now
- Australia’s Q4 2025 connections scorecard highlights end-of-year commissioning progress
- China’s end-December 2025 figures quantify the latest annual storage build-out
- Both updates land as power systems expand storage alongside renewables
Why it matters
- More grid-scale storage can help integrate variable renewables and support reliability
- Connection and commissioning throughput signals near-term capacity additions
- China’s scale-up underscores global momentum in battery deployment
