Energy Insiders Podcast November 17

Print Friendly, PDF & Email

As Australia wrestles with its next move forward in the energy transition, California Energy Commissioner Andrew McAllister joins Energy Insiders to explain that state’s approach to high renewables targets, storage, energy efficiency and demand management.

McAllister has led the solar programs and the local generation programs for California, and is now leading its focus on energy efficiency in a state with no coal, about to close its last nuclear stand, and with gas on the nose thanks to explosions and leaks at gas storage facilities.

His focus on energy efficiency and demand management, key tools as California takes aim at a renewable energy target significantly higher than Australia. And remember, California’s economy is the biggest in the US, and ranks as one of the biggest in the world.

McAllister will appear at the energy efficiency conference in Melbourne this coming week and his observations are timely ahead of the COAG energy ministers meeting and its contemplation of the latest proposals from the Energy Security Board about the National Energy Guarantee.

And, as usual, regular Energy Insiders Giles Parkinson and David Leitch discuss the week’s news, including the Victoria auction for renewables.

    Loved that podcast…..very informative. Thankyou David and Giles.
    I have a 10Kw solar system… I take it that that is what you describe as behind the meter? But I still end up Paying my retailer Energy Australia approx $3000 per quarter and am using according to my latest bill 84 Kw per day….I take it that that DOESN’T include my own Solar resource? How much more Solar would I need to install and Battery storage for my business which runs from 6am till midnight ie 18 hours a day to get my Bills close to Zero? Anyone able to point me in the right direction? Here’s hoping. Many thanks if anyone can as I am no expert but definitely a HUGE GREENY and an avid reader and listener to RENEW ECONOMY and ONE STEP OFF THE GRID
    cheers Rob

      Rob, answering your question will require a very detailed look at your electricity usage. However, if you have not already done so, I suggest you start by looking hard at the efficiency with which you are using electricity. If you can drive your usage down a long way, then satisfying a smaller demand using PV and batteries will be much easier. The other issue to consider will be time of usage: can you run your most energy demanding equipment only during daylight hours?

      You will need some kind of measurement program and possibly the services of an energy consultant.

        Thanks Farmer dave….I have already moved most of my usage to daylight hours and my solar system sucks it dry, (I got back $1.95 on my last bill lol) I know I need more but have 3/4 of my current roof space already covered with solar……. just got a quote from fielders steel to build a large carport 4 metre high covering my whole drive way and above my 4 car garage (which is my rumpus room ($21k for materials alone)…….then installing another 20 or 30 kw system plus 2 to 3 tesla latest batteries plus moving to 3 phase……the cost is blowing my mind…..$100k? I run my business from home….a cleaning company (very upmarket) so I have 5-6 washing machines and dryers going 18 hours a day cleaning nappies……..the best cleaning clothes ever…..ask any old nan………so the load is spread evenly from 6 when I get up till midnight when I get a well earnt 6 hours off!

          Wow, Rob, that is definitely a full-on business! If you have a good look at you will see that some of those appliances have a wide range of efficiencies. Clothes dryers are the best example. The cheapest tumble dryers use electricity to heat the air that is blown through the clothes, and they use a lot if power, because it takes a lot of energy to evaporate water. The next batch are the condensing dryers, which use the incoming air to condense water out of the exhaust air. This pre-heats the incoming air and reduces the energy usage significantly, as well as reducing the humidity in the room from the exhaust air. Finally, the most expensive dryers are the heat pump dryers, which use a heat pump to heat the drying air and also recover the heat by condensing the water vapour out of the exhaust air. Heat pump dryers are not cheap, but then neither is your planned system extension.

          If I were in your situation, I would want to convince myself that both my dryers and my water heaters are absolutely the most efficient available, as even a few percent improvement will make a difference when usage is very high.
