Thoughts of former Chairman of Macquarie Power: Interesting, but Disturbing Information

Liddell Power Station

In digging around for ‘Energy Crisis’ data, I contacted the former Chairman of Macquarie Power, Evan Rees, whom I have known for many years, looking for some best evidence on Liddell Power Station. As a result, Evan provided the response to my question below,  that provides some very interesting, but disturbing information:

Here is Evan’s email to me on 14th October 2017:

Hi John
                                As you know I was Chairman of Bayswater and Liddell power stations from 1996 till 2008. During this time we spent millions on up grading facilities to ensure that their life was extended and we also did a study on building a third plant called Bayswater 2 . The govt. did not strip maintenance funds from us. We had a $300M per year, depreciation figure which we used to enhance the future continuation of the business. In fact the treasurers both Michael Egan and Michael Costa were very supportive to us improving the business.
                                In 1996 the biggest problem facing Liddell was their control systems. These were replaced with a DCS system over two years.

This system was state of the art and good for another at least 20 years. We spent some $30M on this and there is not a plant in Australia that has a more modern system. We went from 4 control offices to one.

                                Next we upgraded the Dust Collection system to the best standard.

                                In approx.. 2002 we upgraded the 4 X 500Mw turbines with new state of the  art Turbines that paid for themselves with efficiencies.

From memory we increased them to 6ooMw and improved efficiency by 7 %. Which is a lot in this type of equipment. This production improvement and coal saving per Mw produced gave us something like a 5 year payback. Again with regular care and maintenance [R&M ] this plant could last 20 to 25 years. 

                                The boilers are a different problem they are old but again we tackled the main problem areas. Boilers by nature are self-destructive and require costly and regular attention. 

However what we did we re-engineered many of the regular trouble spots such as Ash-handling, Ash-pumps, water treatment so these areas had the best gear available.

Boilers did have some internal changes to reduce repair costs.

                                In my opinion if you had the WILL to keep this plant running it can be done. The cost is easily off-set by current power prices. We had this plant making handsome profits with a dispatch price of $27 / Mwh.

Today's dispatch price is in excess of $ 100/Mwh.

                                Added other plant to reduce costs of production for Bayswater and Liddell and make provision for a new " Clean Coal Plant " of 2000 Mw with the following additions.

  1. To ensure that the plants were Drought Proof we increased pumping capacity at the cost of $60M
  2. To ensure that increased coal demands in the future and reduce current day costs we put in a coal unloader that could take the largest of Coal Trains at a cost of $100M
  3. Started two new coal mines to provide ample coal into the future. I believe AGL is aiming to sell this coal to an exporter and so make millions of profit. At the time of sale these contract between buying and selling were worth in the order of $3 Bill.
  4. The new " Clean Coal " station was to be on existing land held by our company. It would be what we call a " Brown Fields " site . This site had Geo-Tech testing and approved. EPA provisionally approved the air quality. So all the major impediments had been covered. On a dispatch figure of $30/ MWh and allowed to run at full performance 24 X 7 Hrs it had an investor return of 30% ROI. The idea is that you would run the new more efficient plant to full capacity and flex the older plants like Liddell.

                                                John, I believe that the management of AGL are conspiring to close coal fired plant to make power cost go much higher and improve their personal wellbeing. One of the Power Engineers did a brief estimate of how many Wind Turbines are required to replace Liddell's Power capacity. He said if you placed all the turbines in the most favourable place for breeze ie on the coast then if you put them starting at Sydney North Head and inland as far as Strathfield. You would need to extend the field as far as Byron Bay.  The shear cost of the Turbines and the subsidy will send Australia broke.

Regards Evan

Evan has confirmed that I can use this information and he is happy to confirm his statements.

When Macquarie handed over Liddell to AGL, we had a plant at Liddell with an estimated life of 20-25 years that was delivering to the Grid at $27 - $30/MWh and providing in the order of 30% Return on Investment.  

AGL is now being paid >$100MWh despatched to the grid that must provide a financially viable and profitable operation, so they are obviously not operating Liddell at a loss.

To suggest Liddell has reached the end of its life by 2022 is obviously untrue and therefore, there must be a reason other than lack of plant profit generating capacity to justify its early closure.

If AGL is exploiting energy market opportunities to gain highly elevated income by its unnecessary but deliberate restriction of supply to the grid from a plant that could efficiently and profitably delivered higher output, in order to obtain an elevated despatch price to the grid to the consumers’ major financial penalty,  would AGL be in legal breach of the Trade Practices Act ? 
If so, what can be done to correct this Restrictive Trade Practice ?

European Hypocrites chastise Trump, Buy record Coal.

As reported by the Washington Times (link), Germany, France and Italy 
chastised President Trump for rejecting the Paris climate accord in June and mocked the U.S. for turning its back on the environment, their nations were busy importing record amounts of American coal. 
The U.S., federal data show, is seeing something of a coal renaissance, but the boom — partly the result of Mr. Trump’s aggressive policies to roll back Obama-era regulations on the fuel — largely has benefited foreign markets. Some of the biggest buyers are also the biggest critics of the Trump administration’s climate policy, including China and leading European nations that now claim to be the world’s leaders on fighting global warming.
So much for the Paris Climate Accord.
