    “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...

    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...

    Lower energy prices? More than just hot air

    The Victorian Government launched Australia’s first offshore wind targets as part of its transition towards a net-zero emission future. According to the target, 9GW of offshore wind will be installed by 2040, nearly quadrupling the total wind capacity in VIC. In this Chart of the week, we dive into the...

    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...

    Feeding the future NEM – Eat some now. Save some for later.

    As the NEM continues to transition towards increased penetration of variable renewable energy (VRE), the use of the word ‘curtailment’ has also increased. While curtailments have historically been a natural part of market outcomes (i.e. generators withholding capacity at higher price points), the increased prevalence of curtailment of VRE is...

    Australian Chart of the week | Going for green: record level of wind generation in the NEM

    In the spirit of the Australian Olympic team, instantaneous wind generation in the National Energy Market (NEM) reached new heights during a blustery end to July. Output hit a record 6,427MW at 8:05 pm on 25 July, after breaking 6,000MW for the first time just the day before. In this...

    Australian Chart of the week | Gassed out: are renewables running gas out of the market?

    Last week, the Australian Energy Market Operator (AEMO) released its ‘Quarterly Energy Dynamics’ (QED) report for Q4 2020. The report highlighted that operational demand has fallen to its lowest quarterly level since 2001; largely driven by mild weather and strong uptake of rooftop solar. Coupled with record high wind and...

    Australian Chart of the week | Push it to the limit: the evolution of MPC & market tightness

    With summer officially starting last Tuesday, the National Electricity Market (NEM) is about to go through the season that typically has the highest demand. Market tightness usually seen during summer sometimes pushes power prices to their maximum level – the Market Price Cap (MPC) – currently set at $15,000/MWh. In...

    Australian chart of the week | SA shatters record: lets talk about the elephant in the room…

    As springtime rolls around in the NEM, those with interest in the market are always keeping an eye on South Australia to see just how low operational demand will go and when (not so much if) the record will be broken. This year has not disappointed. On 11 October 2020...

    Chart of the week | Critical Link: Western HVDC & wind in the BM

    On 10 January, the Western Link HVDC suffered a fresh unplanned outage. This consequently prompted Ofgem to investigate National Grid Electricity Transmission and Scottish Power Transmission over the cable's delivery and operation. Coinciding with this outage was record-high levels of wind generation in Great Britain. This generation from transmission connected...

    Chart of the week | Get a load of this! Wind output in January 2020

    January 2020 was a groundbreaking month for renewables due to high wind performance. Consequently, National Grid ESO announced Great Britain's electricity system in January was the greenest on record. This week's Chart of the week discusses the record-breaking performance of wind. As well as its effect on onshore and offshore...

    Pixie Chart of the week | The changing face of German onshore wind

    The results of the 1 August auction for onshore wind in Germany confirmed a perhaps surprising trend: the sustained fall in auction prices throughout 2017 has been overmatched by the rising prices throughout 2018. Tri-monthly auctions have been held since May 2017. The first delivered a price of €57.10/MWh (£51.40/MWh)...
