In September 2009 I presented a slide deck in this blog which showed the carbon content per kilowatt hour of electricity consumption. It broke down the content into the carbon content inherent in the generated power plus a component for that lost in the network. Hence, if you are buying power in NSW you had 0.89kg of carbon per kwh, whilst in Victoria you were getting 1.22kg. Thus, according to the table below you can see your new carbon tax is potentially going to add 2.0 kwh and in Victoria its going to be a massive 2.8¢. Don’t start congratulating yourself though if you do business in NSW, due to the state of the distribution network there it losses a lot more and the difference drops to 2.4¢ for NSW and 3.0¢ for Victoria.
Now, as the Government states on its website, that’s not much of a hit for your average household. For large businesses on the other hand it will be huge. In June 2010 I put up a graph of a University campus just outside the Melbourne CBD. So, with their carbon emissions at around 57,000 tonnes from electricity alone, the impact will be around $1.3million in increased electricity charges.
It strikes me that there are a lot of businesses that are in for a substantial rise in electricity costs soon. For any business that negotiates on a three year contract basis, and last did their negotiations in 2008, there is a nasty surprise out there regardless of the carbon taxes impact. Many large businesses in that year managed to negotiate an electricity price somewhere between 8¢ and 10¢ a kwh (which is the range for the campus above). So, without thinking about negotiating power, I went to the Australian Bureau of Statistics to look at price increases over the last 30 years.
The first stand out is that the CPI numbers for electricity in Sydney have increased some 45% in the last three years! The other standout was the increase last year was 21.7%, the largest increase since 1983 (25.3%) which was on top of a 25.8% increase in 1982! Didn’t we have a nasty recession then with unemployment way above 10%? The upside of course is that this increase is supposed to feed through to new infrastructure which should mean loss from the network should be reduced and hence the carbon tax impact lower! (yeah, right).
So, what to do? Well, electricity isn’t getting any cheaper as we can see, so we could stop using it. Hmmm, not good for business really, is it? What if we became more efficient? Not possible? Absolutely possible! I was heartened by this article by Ben Cubby in Saturday’s Sydney Morning Herald that NSW businesses are making use of the options available to them to improve efficiency. Also have a look at this clip on YouTube on how just changing your asset maintenance regime can cut consumption by 10%.
