Case Study of inertia supplied by source in the NSW grid on Tuesday 14th November 2023
With GenInsights Quarterly Update for 2023 Q4 completed, and some time till the end of 2024 Q1, we’ve looked back at Tuesday 14th November 2023 (when AEMO had concerns about low System Strength in NSW) and looked at the level of inertia actually seen in the grid. A useful Case Study to say ‘what would have happened without Eraring?’
Consultation opens (and webinar next Friday) on Design Paper for ‘Capacity Investment Scheme’
On Thu 29th Feb 2024 (a day when NSW saw high demand, was stretched in terms of available capacity, and benefited from the electricity and other services provided by soon-to-close Eraring) the Dept of Energy in Canberra released a Design Paper on the expanded Capacity Investment Scheme. A very appropriate day for release …
So how much did Eraring Power Station supply, of the NSW electricity consumption, at peak demand time on Thursday 29th February 2024?
Last article (on the day) about Thu 29th Feb 2024. Prompted by an AFR article just over 24 hours ago, how large was the contribution of Eraring Power Station to the NSW electricity region today?
We’re not building enough replacement dispatchable capacity
With completion of GenInsights Quarterly Update for Q1 2023 approaching, and following some conversations recently (and probably this week at EUAA Conference) here are two charts looking backwards just at fully dispatchable plant that highlight one of the ways in which ‘the level of risk in the NEM is escalating’.
Current expectation for closure dates of Liddell and Eraring Power Stations
Drawing from GenInsights Quarterly Update for Q4 2022, and the next version of our ez2view software, we take a look at the *current* expectations for closure of Liddell Power Station (within weeks) and Eraring Power Station (in 2025). A segue into this week’s update to the ESOO, perhaps?
How much capacity would be required to replace Loy Yang A power station?
Following the published note of scepticism/concern about the energy transition from several industry CEOs in the AFR on Friday, we take a quick look at the replacement capacity needs just for Loy Yang A power station to illustrate the enormous scale of the challenge.
Queensland spot prices on Wed 8th June 2022 … a (discordant?!) Symphony in 3 Movements
Wednesday 8th June 2022 saw bust-boom-bust supply-demand balance, with yo-yo pricing resulting. Very topical, given discussions in various parts about a capacity market.
NEM-wide minimum demand (in winter) drops lower on Sunday 15th August 2021 … and Renewables Share in VIC higher
Sunday 15th August saw lowest level of Operational Demand in the NEM for a winter period, NEM-wide. This also led to a number of other outcomes (including higher renewable penetration, negative prices, … and chatter on social media).
Daniel Westerman’s ‘Big Hairy Audacious Goal’ (BHAG) announced on 14th July 2021 – 100% instantaneous by 2025 NEM-wide
A back-dated article looking back at Daniel Westerman’s keynote address at CEDA on 14th July 2021.
Some are waking up to the shortcomings of current methods of support for ‘Anytime/Anywhere Energy’
A couple glimmers of hope spotted recently, that there might be some (belated) awareness that the current methods of support for ‘anytime/anywhere energy’ are not scalable, or sustainable.
Two papers released by COAG Energy Council are early stages in fleshing out ‘NEM 2.0’
Some brief initial thoughts, following the release of two discussion papers by the COAG Energy Council – the first on two-sided markets, and the second seeming to cover two different challenges (forward markets, and ‘Keeping the Lights on Services’).
We’ve been killing New Entrants with kindness?
Last week saw more in a growing series of exits, and asset write-downs, amongst new entrants in the supply of renewable energy within the NEM. Today on WattClarity I ponder whether we have been setting them up to fail due to the nature of support provided to these new entrants. What is your perspective?
Review of extremes in ‘Raw Off Target’ performance through 2019, with the Generator Statistical Digest 2019
Using the (hot off the press) Generator Statistical Digest 2019, we take a look across all 304 DUIDs to see how they performed through calendar 2019 in terms of large excesses in ‘Raw Off-Target’ in both directions. These results suggests implications for the future…
Four quick thoughts, as the run of negative prices in Queensland continues…
The run of prices at $0/MWh and below is continuing in Queensland region this week as we pass into spring (many dispatch intervals today down as low as the Market Price Floor at -$1,000/MWh). This begs a few questions…
Assessing the diversity of intermittent (wind and solar output) as one piece of analysis in the Generator Report Card
In terms of diversity of intermittent supplies, we need to understand that we’re not just comparing data series on a scale that runs from “highly correlated” to “random”…
