Schneider Analysis Finds Renewable Energy Would Cut Electricity Price
April 18th, 2014 by Giles Parkinson
Analysts at French-based energy components company Schneider Electric have concluded that extending or expanding Australia’s renewable energy target would lead to lower electricity prices, lower carbon emissions and increased competition.
Reducing, or removing the renewable energy target – as many incumbent generators, industry lobby groups, state governments and some of its own members are urging the Abbott conservative government to do – will have the opposite impact, pushing prices higher and creating a greater reliance on expensive gas-fired generation.
The conclusions in the white paper have apparently surprised even the four-man team from Schneider that conducted the analysis, and the unnamed large energy users who commissioned it. Large energy users have normally been against the renewable energy target, and this study – along with others that have reached similar conclusions – is causing a rethink.
The Schneider Electric analysis says Australia will benefit from maintaining, extending or expanding its large scale renewable energy target (LRET) because renewable generation has lower emissions and lower marginal costs than do fossil fuels- fired generation.
“As a result of the influence of the LRET on the generation mix, electricity generation emissions in Australia are forecast to be lower under the LRET than would be otherwise,” it says.
“Again, the LRET becomes a hedge against rising carbon prices, and may help to keep carbon prices lower as a result of the lower emissions.
“Finally, and most strikingly, is the impact of the LRET on long-term energy prices. The LRET is forecast to result in a generation mix with lower marginal cost, lower carbon emissions, and increased competition in the electricity market, all which serve to reduce prices.
“Even after taking into account the cost of Large-scale Generation Certificates, the LRET in its current form is forecast to result in prices lower in the long run than those under decreased targets or outright removal of the Large-scale Renewable Energy Target.”
The analysis is important in the light of claims made by incumbent generators about the cost of the renewable energy target on consumers, and some even wilder claims in conservative commentators that renewables could add 50 per cent to consumer bills by 2020.
Pacific Hydro general manager Lane Crockett said the analysis by Schneider and others clearly demonstrated that zero fuel cost renewable energy can act as a hedge against future price rises in coal and gas.
“This report by Schneider is one of a number of recent reports that clearly demonstrate that deployment of renewable energy technologies via the renewable energy target has played a major role in keeping wholesale electricity prices down and is likely to continue to do so provided it is largely left alone,” he said.
“This report is no real surprise and clearly shows that that promise of a cleaner, cheaper energy market is now closer than ever to becoming a reality.”
One of the key issues facing Australia is the prospect of soaring gas prices.
“Natural gas prices are forecast to rise as LNG exports grow to Asian markets,” the report says. “The influence of the LRET on the generation mix results in less natural gas-fired generation capacity than in scenarios with the LRET Reduced, Removed, or Delayed.”
“A reduced reliance on gas-fired generation means the requirements of the LRET, specifically the renewable generation capacity requirements, become a hedge against the potential for rising natural gas prices.”
The study canvasses several scenarios for the LRET – left as is, removed, delayed or decreased (the three most likely outcomes from the Abbott government’s RET review, or increased, where the fixed target is raised from 41,000GWh to 55,000GWh.
Although this latter outcome is very unlikely to be implemented, the price chart at the top shows it could deliver the cheapest outcomes for large (and small) energy users. And it would result in a significant increase in the amount of wind generation, although RenewEconomy would hazard a guess that large scale solar would likely take a significant share of the capacity.
