Election fact check: Do green schemes drive up electricity prices?

Not as much as Greg Hunt would have you believe… CEC report says electricity price spikes mostly driven by network costs – costs that are now being reduced by increased uptake of solar and battery storage.

A comprehensive new Clean Energy Council report has highlighted how little renewable energy policies and other “green schemes” have historically contributed to Australia’s rising electricity prices, in comparison to other factors like over-investment network infrastructure.

The linking of high electricity bills to climate schemes like the Renewable Energy Target and emissions trading has been a favourite weapon of the Coalition since Tony Abbott was its leader.

Years later it is still regularly trotted out by federal environment minister Greg Hunt, who argues that the ALP’s plan to boost the renewable energy target and re-introduce an ETS will amount to “a massive new electricity tax.”

But according to the CEC’s 2015 Clean Energy Australia Report, released on Tuesday, the majority of recent spikes in the cost of electricity have been driven by network investment in poles and wires, much of which may have been unnecessary.

As you can see in the chart below, network costs make up more than 43 per cent of charges in domestic electricity bills, while 7.4 per cent of costs are attributed to “environmental policies”. The cost of transporting electricity across the country via the poles and wires network has made up more than half of power bills in recent years, the report says.

“The majority of …previous cost rises were driven by investment in the poles and wires of the electricity network,” the report says.

“How much of this was necessary investment and how much was network ‘gold plating’ … is unclear,” it adds. “But with the benefit of hindsight, a six-year stretch of falling demand for electricity meant that more was invested in our poles and wires than was ultimately required.”

Interestingly, the report says that power prices – which have stabilised over the past year – are projected to remain “mostly unchanged” over the next three years, despite remaining “a politically-charged battleground.”

Indeed, it notes that the price of electricity may actually fall slightly in some states in 2016, due to decreasing network costs in the short term – savings it suggests may be connected to increased adoption of renewable energy sources like rooftop solar.

“As storage becomes cheaper and more mainstream, it is expected that the interaction of solar and battery storage will help to shave off some of the expensive demand peaks, such as on very hot days when air-conditioning is being widely used,” the report says. “This will help to reduce overall costs for consumers.”

    Look, in Victoria, most people don’t know this, ring up your electricity supplier (or switch suppliers) and get 30% off your electricity bill. Minimum. Maybe 34% off. Tell everyone. It is that simple. Just ring up. Threaten to switch. Boom. Rising electricity costs solved, at least for a while…

      Absolutely, just use this comparison site for Victoria: https://compare.switchon.vic.gov.au/

      There are more retailers than ever. Also switch to ToU if it saves you more.

    I have looked at the numbers and the simple fact is, yes Renewable Energy costs did contribute to an increase in price, however at the same time the fact is it lessened the wholesale price by a larger amount.
    The simple fact is the more Renewable Energy that is implemented the lower the production cost is going to be, everyone knows this.
    There is no argument about the establishing effect of implementing RE.
    The only ones who will put up smoke screen arguments are those who can not leverage $12,500 a MwH prices for a few days of the year.
