A collation of articles related to the consideration, approval, implementation and outcomes of the IESS rule change in June 2024 … which leads to:
1) The implementation of BDUs (Bi-Directional Units) and
2) The implementation of Hybrid units.
The NEM’s first true solar-battery hybrid in the NEM — the 98 MW Quorn Park Solar Hybrid with a 20 MW BESS — has begun testing as the inaugural “mixed” Aggregate Dispatch Group under AEMO’s new rules.
No Mixed aggregate dispatch groups have been registered.
Units typically cut over to their BDU counterpart in 2 weeks once the BDU was registered.
A summary of the key challenges facing standalone solar and wind farms over the past several years, along with discussion and thoughts about whether new rules surrounding hybrids systems will address these.
It's day 1 of the CEC's Clean Energy Summit ... perhaps a fitting day to see first operations of a (single unit) bi-directional unit?!
Today, 4 July 2024, we see the first bidirectional units (BDUs) effective in Production in the Australian NEM (National Electricity Market). This new category of unit was created to improve integration of energy storage systems into the NEM. Changes to dispatch systems went live on...
With the clock ticking down to the staggered migration of battery unit registrations to the new BDU (bi-directional unit) format, in this article we recap our current expectations.
Ellise Janetzki posts this overview about operating hybrid plants, following her presentation at the Clean Energy Council's ALSSSS event in Brisbane earlier this week.
A short note (on Monday 3rd June 2024) with the IESS changes going live today.
A question from a WattClarity reader this morning prompts this quick-and-cryptic review of NSW price volatility at 18:10 on Monday 20th May 2024, and particular output profile of Queanbeyan BESS
A short, belated (and back-dated) article about the change to the original IESS Rule.
On 7th July 2022 the AEMO published the final ‘High Level Design’ for the IESS implementation.
Same day as we released GenInsights21, the AEMO published its High Level Design on how they will implement the AEMC Rule Change determination on Integrating Energy Storage Systems (IESS) into the NEM. Here's the key dates.
Earlier today, the AEMC released a final determination on a market rule change regarding the registration and participation of storage systems in the NEM.
