Centre for Policy Development recommends to Australia – go for rooftop solar

The CPD report reaches five major conclusions about the benefits of rooftop solar:

• It lowers wholesale electricity prices for all consumers –  as long as retailers pass these savings on. It estimates these savings at $300 to $670 million a year in wholesale electricity costs, based on prices in 2009 – 2010.1

• It gives consumers real choice about their electricity supply and control over their bills, noting that competition between electricity retailers is meant to lower costs, but ends up adding to bills.

• It can reduce summer peak demand, which may lead to more productive use of existing network infrastructure that consumers have already paid so much for. And in some places, it may also defer or avoid network investment.

• It creates a base of consumers actively engaged in managing their energy demand. This will be critical to avoid expensive network investment if climate change increases peak demand from air conditioning

•  It helps insure Australia against future electricity price shocks from gas price volatility and drought. Prices for gas-fired electricity are now linked to volatile international oil prices. Drought can reduce electricity supply from water- cooled coal-fired power plants, raising wholesale electricity prices. It says prices could spike by up to A$250 per year, similar to the amount network charges have added to the average annual household bill since 2007.

Rooftop solar – natural hedge against dirty energy system REneweconomy, By Giles Parkinson on 30 April 2013 A new report from the Centre for Policy Development recommends that Australia fully embraces solar energy as a hedge against volatile gas prices, and future electricity price shocks that could be caused by drought.

The report says rooftop solar can save consumers money, gives them real choice, improve competition and help address network problems. Already, one million homes have rooftop solar PV, and at the very least a million more should follow in coming years, even without high incentives that assisted the initial take-up.

It notes rooftop solar should play a key role in the transition of Australian electricity system to a “cleaner and affordable alternative”, but it warns that the technology would likely face fierce opposition from powerful interests seeking to protect their legacy assets, who are seeking to exploit a political divide over renewables.

CPD says that current political stalemate is preventing the emergence of a long-term policy vision consistent with community desires to realise the benefits of renewable energy. It estimates that in 2012-13, effective support for existing coal-fired electricity was $3.6 billion per year, compared to $1.4 billion for renewable energy.

“Politicians need to base their decisions on where our electricity system is going. Governments which back legacy technologies, while ignoring growing community desires for renewable energy, will face political fallout.”

So far, there has been little sign that politicians understand this. Renewables, particularly solar, are usually portrayed as the villain in rising electricity costs, even though transmission and distribution costs – much of it to support ageing networks and the boom in air-conditioning, and some of it probably not needed at all – have been by far the greatest contributor……..

This, though, is the first report that looks in detail at the Australian situation. As lead author Laura Eadie toldRenewEconomy: “Issues such as electricity price security risks are  just not in the public debate around renewables. We see that constantly. No one is looking at the long term, looking at the benefits, and a lot of the discourse comes  from the assumption that renewables will be more expensive. We are trying to reframe the debate a bit and dispel the well-spread myths that renewables are inherently unreliable.”
