While much of the attention in the Balancing Mechanism (BM) focusses on how flexible technologies such as gas, coal and, increasingly, batteries are being commercially utilised, less is often spoken about the role of wind.
This week’s Chart of the Week provides detail on this recent trend and importantly who is being called on from the wind market and why.

Low carbon generation
As the grid transitions to much higher levels of renewable penetration, the range of generation outcomes on any given day increases. The worst of these ranges are known as dark doldrums when there is a combination of poor conditions for wind and solar generation, usually a windless day in winter....
Commercial and market outlook
The Federal Government has legislated emissions reductions of 43% below 2005 levels by 2030. Sourcing electricity from renewable technologies is fundamental to meeting this, with a much-publicised target of 82% renewables in the grid by 2030 – up from a current value of 38% over the last year. Fortunately, the...
Commercial and market outlook
On 9 October 2023, 1pm (market time), the dispatch of the new Very Fast (VF) FCAS market in the NEM will commence and will add two new markets for contingency FCAS, Raise 1 (R1) and Lower 1 (L1). AEMO has released a final industry go-live plan to keep track of...
Low carbon generation
Penetration of renewables continues to dominate the energy news, as we saw renewables as a proportion of total demand reach new heights this week to a new record of ~70% penetration. In light of this continuing march toward a renewable-dominated grid (building on some analysis we did in Chart of...
Low carbon generation
The Australia-Asia power line proposed by Sun Cable will connect a 17-20GW capacity solar plant to Darwin with an 800km High Voltage Direct Current (HVDC) transmission line, which then connects to Singapore via a 4,500km HVDC transmission subsea cable (Australia-Asia-powerlink). Expected to be operational by 2027, the $35 billion project has...
Commercial and market outlook
Although not quite as thrilling for some as the search for the Holy Grail, finding a way to minimise causer pays costs continues to take the focus of both wind and solar farms. Using the FI value through self-forecast systems[1] has become increasingly prevalent for these assets in an effort...
Low carbon generation
In the last week, renewable generation in SA has varied from 126% of local demand to only 0.6%. During this period of low wind in the state, SA was importing ~600MW from Victoria. At that same time, renewables were thankfully generating 34% in VIC, along with brown coal pretty much...
Commercial and market outlook
The announcement on Friday that QEnergy and Mojo Power will no longer provide retail services illustrates the battering Australian electricity retailers have faced over the last year. High hedging costs, especially for non-vertically integrated retailers, have seen smaller retailers hit the wall, such as Elysian Energy, Enova Energy, and Power...
