AEMO declares system strength shortfall in Queensland after wind, solar curtailed

AEMO has made a formal declaration of a “system strength shortfall” in North Queensland, that applies to the 275kV node at the Ross substation, and further explains why three wind and solar projects in the region were hit with directions to cut output .The declaration of a fault level shortfall now places an obligation on the transmission network service provider Powerlink to ensure the fault is addressed.

Australia’s clean energy transition delayed due to outdated electricity market design

In December 2019 the market operator (AEMO) published its Draft 2020 Integrated System Plan (click here) (ISP).This document confirms other researchers’ earlier analysis which found that the cheapest option to replace the old coal-fired power stations is wind and solar, supported by energy storage and transmission.

South Australia re-connected to main grid as AEMO completes delicate operation

The South Australia electricity market has been re-connected to the main national grid after the Australian Energy Market Operator completed a delicate operation to “resynchronise” the state using a temporary single line that was completed in little more than two weeks after ferocious storms tore down the main link with Victoria.

Solar and wind curtailment reached record levels in 2019, says AEMO

Solar and wind curtailment reached record levels in 2019, says AEMO

AEMO says self-curtailment from solar and wind projects over the quarter was highest on days with extended negative spot prices, such as on November 11, when a record high of 968MW of output was curtailed at 1300, coinciding with low daytime demand, transmission outages, and a spot price of -$343.33/MWh. System strength constraints in South Australia, and transmission outages and other network constraints, had also contributed to curtailment levels “much higher than historical outcomes,” AEMO said.

AEMO to meet wind and solar industry over NSW, Victoria grid blockages

The meeting called by AEMO follows widespread concern in the industry about the issues affecting the grid – and particularly newly identified “system strength” problems – which has resulted in the output of five major solar farms being reduced by half , and other ready-to-roll projects told they face potentially significant delays on connections and commissioning.

AEMO warns of added costs and delays to new solar projects in Victoria, NSW

AEMO warns of added costs and delays to new solar projects in Victoria, NSW

Two weeks ago, as RenewEconomy reportedly exclusively, five solar farms in the West Murray region of the grid – Broken Hill, Bannerton, Wemen, Gannawarra and Karadoc – had limits imposed that cut their capacity in half ( a total of about 170MW) because of new modelling that suggested voltage oscillation and system strength issues could emerge under certain situations.

Australia has to look forward on energy, says Zibelman: “We have no choice”

Australia’s exit from from coal and transition to a renewable grid is tracking not only ahead of most of the rest of the world, but is coming faster than almost all of us would have predicted, the head of the Australian Energy Market Operator has warned.“We have to look forward, we have no choice in Australia,” AEMO chief Audrey Zibelman told the audience at Australian Energy Week 2019, in Melbourne on Wednesday.

Denial and confusion live on, as energy hopes turn to states and AEMO

That same sense of emptiness – like a deflated balloon – was experienced across the country, at least for the one half of the population that didn’t want the Coalition to retain power, and for those in the energy and the electric vehicle sectors who had assumed that they would finally have a government happy to shift policies to embrace the 21st century.

Victorian summer review: It’s time to prioritise peak demand reduction

This is particularly salient given the voluntary and involuntary load shedding that occurred in Victoria during extreme heat on Thursday 24 and Friday 25 January, 2019.Importantly, load shedding initiated by the Australian Energy Market Operator (AEMO) was in effect a demand response when supply was not adequate to meet demand.

AEMO confirms big de-ratings for wind and solar farms, reprieve for some

AEMO confirms big de-ratings for wind and solar farms, reprieve for some

The issue over MLFs has been a controversial one in Australia, particularly in the last few years as many wind and solar farms – and other generators – suffered big de-ratings as a result of grid congestion, and the lack of local load to eat up the output.

Wind curtailment falls to one per cent in South Australia

Wind curtailment falls to one per cent in South Australia

In its report released on Tuesday, AEMO said the reduction in curtailment over the first few months of 2019 was driven by increased availability of wind and solar generation in the region, comparatively fewer periods of high wind conditions, and changes to operating guidance.

In its latest Quarterly Energy Dynamics report, AEMO says batteries have increase their share of key FCAS markets from 10 per cent in the last quarter of 2018 to 17 per cent in the first quarter of 2019, thanks to the recent addition of the Dalrymple battery storage plant in South Australia and the Ballarat battery storage facility in Victoria.
