Tomorrow the opposition leader, Peter Dutton, is discussing his plans to introduce nuclear power with anti-renewable energy commentator, Chris Uhlmann. No doubt we will hear the same claims about renewable energy causing electricity prices to be high and the need for nuclear power to keep prices down that both men have said in the past.
And just as was the case in the past, such claims will again be wrong.
The increased use of renewables in supplying electricity is not the cause of higher retail electricity prices – and it is clear that more renewables will lead to lower prices.
Research and data from the Australian Competition and Consumer Commission (ACCC), the Australian Energy Market Operator (AEMO), the Australian Energy Regulator (AER) and the CSIRO all make it abundantly clear that renewables are the cheapest form of electricity, and that the high cost of energy is driven by the cost of gas and coal produced electricity.
It is not surprising that people can be misled about the cause of electricity prices. Australia’s National Electricity Market (NEM) is a complex market stretching to 1,925 pages of rules and regulations such that any explanation of price determination will be greatly simplified.
So let us set out the two key issues to understanding retail electricity prices:
1. The cost of generating electricity (the wholesale price) is a surprisingly small component of the many costs that contribute to household electricity prices.
