    Zap, Crackle, Pop! SA’s shocking electric dance party on the 11th

    Across the mainland states in the NEM, South Australia (SA) relies heavily on variable renewable energy (VRE) resources. SA is an excellent subject to test the premise “What if the wind doesn’t blow, and the sun doesn’t shine”? Negative spot prices persist in South Australia due to an abundant supply...

    Polarisation of wholesale spot prices leads to opportunity for arbitrage services

    Over the last five financial years, South Australia has seen a significant increase in price volatility, with substantial portions of time both negative and above $250/MWh, leading to increasing opportunities for storage systems to provide arbitrage services. A number of events initiated the reduction in wholesale energy prices between $50/MWh...

    “If I don’t get some shelter, ooh yeah, I’m gonna fade away”: How much firming is needed for wind?

    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...

    Feast or famine? FCAS costs in South Australia

    Frequency Control Ancillary Service (FCAS) prices are highly volatile, at times resulting in short periods of extremely high FCAS cost. Three such events in recent history are the South Australian (SA) islanding events in November 2019, February 2020, and November 2022. During these events, FCAS costs in SA totalled $16...

    Casualties of the energy transition highway – market effects of Torrens Island B retirement

    As part of Australia’s energy transition, investments are being made to ensure sufficient network capacity to host renewable energy generation, share them between regions, and maintain power system security and reliability. One of the interconnectors being built is Project EnergyConnect (PEC), which will provide 800 MW of transfer capacity between...

    Christmas comes early for South Australian battery owners

    The choice of Chart of the week was an easy one following Saturday’s storms that ‘reined’ down on South Australia. The state became isolated from the rest of the National Electricity Market after one of ElectraNet’s pylons, supporting the interconnector between SA and Victoria, was knocked down[1].   The consequence...

    State of Storage: Investigating battery profit for NEM states

    It has been an interesting year for Australian energy markets, facing unprecedentedly high energy prices, coal outages, and market suspension. In today’s Chart of the week, we will investigate the impact a BESS would have made during FY 2022. Using Cornwall Insight Australia’s battery simulation model, we simulated a stand-alone...

    A taste of freedom for renewables with syncons in South Australia

    Today wind capacity in South Australia stands at 2500MW, contributing to almost 40% of the energy generation in the state. This is in addition to utility-scale solar and rooftop PV, which contribute 4% and 15% of total generation in SA, respectively. With such a high level of variable renewable energy...

    State election day chills; SA hit $9,934/MWh on Saturday evening 19 March

    SA’s reliance on wind is getting to a point where there is not much to do except importing from VIC and generating with expensive fuel, such as diesel, when wind speed is not at its best shape. In this Chart of the week, we take a closer look at South...

    SA on cusp of 100% instantaneous renewables; gas unit directions remain

    AEMO’s goal of handling 100% instantaneous renewable penetration by 2025 is a significant challenge and fitting, given the pace the NEM is moving to support increasingly higher levels of instantaneous (and increasingly asynchronous) renewables regularly. While this challenge may not be as pressing for all NEM regions, the need to...

    Is the NEM going off schedule?

    Is the NEM getting harder to control with rising variable renewable generation and distributed photovoltaic growth? AEMO’s balancing of scheduled supply is critical to ensure the system remains stable and wholesale prices work efficiently. This Chart of the week briefly examines if the NEM is “on schedule” to meet this...

    Round and round it goes, where the loop flow stops, nobody knows

    A by-product of how market boundaries are defined, loop flows are phenomena in electricity markets that manifest as flows going in one direction across parts of a network loop and goes the opposite way in other parts of the same network loop. Regardless of whether the market design is nodal...

    How deep is your love? A look at the depth of negative prices in South Australia

    The recent rise in the frequency of negative wholesale energy prices in the NEM has captured the attention of many market observers. A less-discussed aspect is how deep these negative prices run. How much additional demand could be added to the system during the negative-priced dispatch intervals before the prices...
