South Australia burning diesel to prop up electricity exports to Victoria

At 10.35am AEST Nemwatch shows SA burning diesel to generate 91MW to contribute to a Region Total Demand of 1,992MW. However AEMO at the same time – says SA demand was just under 1,600MW – which I Sliding-scale agencies can help people get proper bulk viagra psychiatric evaluations.

I assume it pays SA to pay the diesel and gas costs to keep exports up because at times of abundant wind in SA the AEMO Regional Reference Price can go negative.

  1. Right now just after the morning peak Nemwatch shows SA demand as 1,920MW with Diesel making 100MW. Gas is carrying most load at 1,500MW while wind is weak at 250MW. The AEMO 30min graph has Demand at just under 1800. So if you are correct it looks like +100MW is being exported. The 30min graph shows RRP has rocketed to over $10,000 per MWhr. Demand is falling as SA moves towards the daytime trough in demand. Forecast RRP’s for around the evening peak are also up to +$10,000. Surely phone calls could see a few more gas turbines cranked up for the evening?

  2. This article is illuminating – quotes the SA Treasurer blaming a range of factors but he forgets to mention the closure of the Port Augusta coal fired units on 9 May.
    Peak demand electricity price fluctuations hit South Australian businesses 14 Jul 2016
    The article starts off by misleading – it says – “A private power station in Adelaide has been asked to boost its output…” The term “private” implies that there are “public” power stations which is misleading.
    OK so the SA Govt wants Pelican Point to up the output. Why was all this not arranged before the coal fired stations were shut down in May? You did not need a Uni degree to work out that greater load would fall on gas.
    The owner of Pelican Point Power Station in Adelaide’s north-west, Engie, has been asked by the SA Government to provide an extra 239 megawatts of supply.

    The Government said a planned outage of the Heywood power interconnector with Victoria, higher gas prices and severe cold weather were to blame for price volatility in the local energy market.

    Treasurer Tom Koutsantonis said there was little the Government could do reduce price fluctuations because of past privatisation of the state’s electricity assets.

    But Opposition frontbencher Rob Lucas blamed the SA Government’s reliance on renewable energy for the surge in electricity prices at times of peak demand.

    “The massive rush into wind energy and alternative energy in South Australia, without ensuring the continuation of base load power, is the major problem that we’ve got here in South Australia,” he said.

    “That’s completely a decision of the South Australian Labor Government over the last 10 years.”

    Mr Koutsantonis said this week’s severe weather had delayed scheduled works on the interconnector and added to volatility for the energy spot price market.

    He said higher gas prices were also making it difficult for businesses.

    “Gas prices have dramatically increased because of the record cold — people are using a lot more gas on the eastern seaboard in their heaters so [providers] are getting a lot more money for their gas being burnt in people’s homes than burning it to turn it into electricity,” he said.

    “That’s the issue, it’s not about wind, it’s about how much gas costs.”

  3. I see at this WA AEMO front page that was the evening peak – presumably the diesel gen put the best bid in for that time-slot.
    Just quickly – I can not find info for what diesel capacity is in the SWIS.

    To add to your figures above re SA just read this in an industry newsletter (Energy News) Fri 15th in an article “Gas bails out embattled SA”

    ‘South Australia has been forced to take emergency measures to cope with energy prices that have frequently surged above $1000MWh this month and at one point on Tuesday hit the $14,000MWh maximum price, far above the regular price which usually sits below $100/MWh.’

    ‘Power costs in SA are at their highest level in almost a decade, in part because there has been a major shift to wind power. ‘

    ‘Electricity contracts for delivery in 2017 and 2018 are priced at $91-100MWh in South Australia, compared to $50-63 in Victoria, NSW and Queensland.’

  5. As of just after 7pm AEST Friday night Nemwatch showed SA in their evening peak was generating 1,475MW – wind was an insignificant 30MW gas made 1,445.
    At the same time the AEMO 30 minute chart showed SA “Total Demand” was 2,0216MW and the RR Price was $232.67.

    This suggests to me they were importing near 500MW from Vic. allowing for some “spinning reserve”. IMHO that is a large import total. But we do not know the exact details till we get the data files.
