‘From 18:17 (6.17pm) yesterday, AEMO instructed NSW’s transmission operator Transgrid to shed a total of 40 megawatts (MW) of electricity supply near Lismore in response to issues threatening power system security,’ an Essential Energy spokesperson told The Echo.

‘Earlier that day (05:11) (5.11am), Transgrid’s 330 kilovolt Lismore – Coffs Harbour transmission line tripped and remained out of service. At the same time, the nearby QLD-NSW HVDC interconnector, Directlink, tripped as per design and subsequently returned to service.

‘During the evening, Directlink was unable to follow dispatch targets, further limiting the available options to supply power to the Lismore area to meet the evening demand, putting the secure operation of the power system at risk.

After load shedding had commenced at approximately 18:34, Transgrid’s 132 kilovolt Armidale – Koolkhan transmission line tripped and reclosed, and at the same time Directlink tripped and remained out of service.

‘At 19:45 (745pm), electricity demand reduced, allowing the majority of power supply to be restored by 20:00 (8pm), with full restoration by 22:00 (10pm).

Original story:

Power supplier Essential Energy says that around 24,500 customers in Ballina, Lismore and surrounding areas were impacted by an unplanned power outage earlier this evening.

An Essential Energy spokesperson told The Echo that they were directed by the Australian Energy Market Operator (AEMO) and TransGrid to shed load to protect transmission system security.

Essential Energy expects to restore supply to all impacted customers by 11.30pm.

Further information about AEMO and wholesale market conditions can be found at aemo.com.au.

  1. Isn’t it ‘strange’ that the most ‘alternate’ area of the state is targeted ?
    One could possibly infer that some entity wanted to shake up the alternate energy capital of the country, in order to cast doubt on the availability of supply, in order to argue for the introduction of the toxic nuclear scam, so favoured by the likes of Dutton and their ilk.
    This sick course of events would facilitate the continuation of the centralised, easily manipulated and over charged ‘ privatised’ racket, while impeding the roll-out of decentralised cheap energy from a huge variety of stable alternate sources.
    Makes you wonder, G”)

    • I mostly wonder about the intellect behind your comments on most subjects.

      The outage was to protect the transmission system and related to specific transmission lines being tripped. These lines cannot simply reconnect with the full load applied to them so some load must be shed to allow them to reconnect.

  2. Very poorly explained by Essential Energy…please use plain English and explain why no other regions were impacted and why it was only the Northern Rivers….

    • Anton, in case you don’t get it, transmission lines don’t discriminate between electrons generated from fossil fuel energy sources or renewable energy sources.
      Perhaps direct your ‘concern’, if you truly are concerned, to why there was a trip in the first instance that led to the power outage.

    • Actually this is the result of a decade of noalition inactivity with more than 9 different policies with no outcomes. Now they want us to wait at least 2 decades for unachievable, uneconomic and extremely costly nuclear power stations so that aging coal fired power stations could keep operating( no company will build a new one), but luckily they will have been shut down and turned into alternate uses.

  3. In plain(ish) English: a right royal fustercluck! Essential charges us a king’s ransom for accessing energy over their grid system. Why are they unaccountable to consumers?

  4. The explanation was in as plain English as could be used in a technical context. It is your problem if you couldn’t understand it.

    Directlink is the QLD-NSW interconnector.

  5. I agree with David Williamson – the explanation is in technical jargon – unable to be understood by most of us who lost power unexpectedly.
    What went wrong? why were we chosen? – or weren’t we chosen? – Is it likely to happen again? – was it out of the control of the power companies? Does it mean we should be getting support to get subsidies for batteries?, etc

  6. And at exactly the same time, we’re being told to switch from cooking our dinner with gas to cooking electrically and to buy EVs, which need recharging once people get home. 🤪🤔

  7. My solar panels didn’t work, since it was at night, and I don’t have a battery which of course most people cannot afford, just like quality food. Just keep building solar farms over prime agricultural land – that’s the green solution. No energy, no food then no people. No people no problems, according to the Malthusians.

    • Maybe go check the solar system near Ebor and see the sheep grazing around the solar arrays, then stop listening to the lies coming from the anti renewable NATs.
