References to WattClarity in today’s session of the Senate Committee on Energy Planning and Regulation in Australia (between Matt Canavan and Daniel Westerman) spiked our interest – and, given the topic was NSW unit outages on Wednesday 27th November 2024, we took a quick look.
Today the AEMC weekly email notes that:
‘We will use the standard rules consultation process to assess Delta Electricity’s proposal to allow cash as credit support. We received a valid objection to the proposed use of the expedited process, meaning the standard approach will be used instead.’ Also today was the closure date for submissions (as noted in the Consultation Paper).
A short note today (thanks to a tip by Thomas MacDonald) about a ‘relatively urgent’ rule change request by Delta Electricity that might help Vales Point operate into 2025.
On Tuesday morning 21st May 2024 the Vales Point 6 unit has returned to service, ~2 days earlier than earlier expectations.
An early afternoon look (Sat 18th May 2024) about the delays in return to service for the forced outages at two NSW coal units (Eraring unit 2 and Vales Point unit 6).
Another ‘forecast LOR2’ notice from AEMO … this time looking at Sunday evening 19th may 2024.
A quick look at the trip of Vales Point unit 6 on Friday afternoon 17th May 2024.
An inspection of bids and dispatch outcomes indicates some units helped compensate for the loss of supply with the trip of ER01 and ER02.
Friday 14th July 2023 sees some media articles and commentary about several coal-fired generators running longer than previously thought, as the energy transition hits some speed bumps.
A quick look at the two units tripping at 13:33 on Sunday 7th June 2020, and some earlier operational problems the day before (perhaps unrelated).
This is the 2nd of 4 Case Studies to follow on from Tuesday’s main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings). In this case, let’s look at the ‘worst’ case, in aggregate, where coal units over-performed compared to dispatch targets.
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…
