Q1 2026 QED: batteries, data centres and a system in transition

Batteries are now playing a central role in Australia’s electricity system, and the latest data shows just how quickly that shift is happening.

In this episode of AEMO On Air, Kerry Galloway, AEMO’s Manager of Market Insights unpacks the key details of the Q1 2026 Quarterly Energy Dynamics (QED) report.

In the National Electricity Market (NEM), more than 4,400 MW of new battery capacity has been added in the past year, which has helped shift three times the volume of renewable energy from daytime into the evening peak, competing against coal and gas. Batteries set prices for around a third of the times and contributed to a 12% year-on-year drop in wholesale electricity prices.

The episode also explores the quarter’s record renewable output, with renewables supplying 46.5% of NEM generation, while emerging demand continues to build with 11 large-scale data centre projects (5.4 GW) progressing through connections.
