Renewables for industryProject AGL Broken Hill Grid-Forming Battery
This report presents the challenges and lessons learnt during the connection application process of the Broken Hill battery and the approach to design and construct a grid-forming inverter plant compared to traditional grid-following plants.
Broken Hill Battery Energy Storage System (BESS), developed by AGL is a 50MW/ 50MWh large scale battery storage system located 200m from Transgrid’s Broken Hill substation in New South Wales.
The performance of the plant will be verified through an agreed Testing Plan. The Testing Plan will be developed in consultation with Transgrid and AEMO and is expected to include a combination of power system studies, commissioning tests, and ongoing performance monitoring. The findings of the Testing Plan and any other key learnings will be disseminated though knowledge sharing outputs in the form of knowledge sharing reports.
This report specifically addresses lessons learnt in the connection application process of the Broken Hill Battery Energy Storage System and the approach to design and construction for a grid-forming inverter plant compared to traditional grid-following plants.
