Dodo electricity and gas price increases.

I received an email yesterday advising of Dodo increasing their electricity and gas prices. As prices increases our bills go up which isn't a good thing, but it also opens up the possibility that other energy sources may be worth investigating.

The first thing I do is to update the default electricity rate on Energy Cost Calculator which helps me determine the cost of appliances and the payback of using a lower cost appliance. As an example I worked out once the energy saving for replacing and old TV and set-top box with a new more energy efficient TV was equivalent to getting a 30% discount on the TV over a couple of years. Who doesn't want that type of discount. The Energy Cost Calculator shows how much it costs to run an appliance, but also shows the payback period should you wish to replace an old appliance with a newer more energy efficient appliance. If the payback period doesn't interest you I created a simpler version of the calculator which is available at Electricity Cost Calculator.

The second thing is it's good to know how much the increase is in terms of a percentage. Here's how the figures pan out. The below figures do not take into account Dodo's pay on time 30% and 20% usage discounts.

Electricity (All prices includes GST)

Daily supply charge cents per day
Old - 91.190
New - 105.435
% increase - 15.6%

Anytime usage cents per kWh
Old - 26.169
New - 28.545
% increase - 9%

We can see from the above the daily supply charge has the biggest increase. Unfortunately you can't reduce this by changing your electricity usage. The only way to change this is to see if you can find a lowest cost supplier.

Overall the increases are quite steep and far exceed inflation.

Gas (All prices include GST)

Daily Supply Charge cents per day
Old - 60.489
New - 67.749
% increase - 12%

Old Peak Usage Rates
Usage - First 98.63 MJ per day - 2.167
Usage - Next 49.32 MJ per day - 1.639
Usage - Balance MJ per day - 1.309

New Peak Usage Rates
Usage - First 98.63 MJ per day - 2.431
Usage - Next 49.32 MJ per day - 1.837
Usage - Balance MJ per day - 1.463
% increase - 12.18%, 12.08%, 11.76% respectively

Old Off Peak Usage Rates
Usage - First 98.63 MJ per day - 2.057
Usage - Next 49.32 MJ per day - 1.562
Usage - Balance MJ per day - 1.309

New Off Peak Usage Rates
Usage - First 98.63 MJ per day - 2.299
Usage - Next 49.32 MJ per day - 1.749
Usage - Balance MJ per day - 1.463
% increase - 11.76%, 11.97%, 11.76% respectively

When these prices take effect on the 7th of December gas prices will increase by around 12% for both supply and usage. Again this far exceeds inflation.

Generally we are quite conservative users of energy, but these increases will still add around $200 a year to our energy costs. As usual I'll review the energy offers of other companies and look at ways of further reducing our energy use. Saving money is one benefit as is the feeling we lower our impact on the environment.
