The AFR article is also at the Grattan Institute website as This year will determine if Australia still believes in energy markets. There is an article at RenewEconomy and the full report, by Tony Wood, David Blowers and Kate Griffiths is here.
This is the status report after a series of uncoordinated government interventions:
- The transition from centralised electricity based on fossil fuels to decentralised electricity characterised by low-emission technologies such as wind and solar is well underway. In Australia this has been primarily driven, not by efficient climate change polices but by a grab-bag of subsidies to support renewable energy. The subsequent failure to integrate intermittent supply sources into the existing system hastened coal plant shutdowns and led to power outages and a greater dependence on gas plants just at a time when gas prices more than doubled. The result: higher and rising electricity prices along with serious and growing concerns about the security of supply.
Doing nothing could cripple the National Electricity market as an efficient spot market and driver of investment and divestment decisions. They suggest three things need to be done:
First, the physical system needs to be stabilised, which will require a combination of existing and new rules and regulations that are suited to the system and technologies we have now. The cultures of the Australian Energy Market commission and operator may have to change.
Second, we need a credible emissions reduction policy that is integrated with the NEM.
the COAG Energy Council needs to identify and address risks to a dependable supply of electricity. This will require changing governance arrangements and the operation of the NEM. The current arrangements between the council and the market agencies are no longer fit for purpose…
The report includes some instructive graphs. Here is generation capacity by state against forecast peak demand:
In the immediate future the system will depend on NSW, which is heavily black coal, and Queensland, which is heavily coal and gas.
Queensland tends to have high prices:
There are plans aplenty, but not much committed as of February 2017, and a surprising amount of gas in Queensland:
Gas prices have roughly doubled in the east cost as domestic supply becomes an appendage to the Gladstone LNG export market. If domestic supply is increased it will still be an appendage to the export market.
Moreover, producing more gas takes time, years of time, and there is absolutely no incentive to increase supply to the point where it will lower prices. market wisdom in such cases is to withhold supply to maintain prices.
So without “severe government intervention”, whatever that might be, high gas prices are here to stay. Calls from suppliers to open up more reserves to bring the price back down are unfounded.
New Australian Energy Market Operator (AEMO) CEO Audrey Zibelman together with the Australian Renewable Energy Agency have announced plans to have 100MW of demand response capacity in the Victorian and South Australian electricity markets in time for the summer peaks and heatwaves. The idea is to pay consumers to reduce their demand at peak times, and to call on stored power, even from car batteries.
To operate at grid level it seems you need demand-response aggregators with smart technology to organise the operation. ARENA is putting up $22.5 million for “reward payments” for a fast response.
They are looking for a “proof of concept” that can then be used to bring in new market mechanisms and rules.
- ARENA CEO Ivor Frischknecht also said demand response would help to facilitate Australia’s transition to renewable energy.
“We need to find new, smarter ways of coping with spikes in demand and volatility as we move towards an electricity system with more variable renewable energy supply.
“Initially, we are seeking to fund demand response to make available temporary supply during system-wide emergencies. In the future, demand response could also be used to smooth out frequency disturbances, network disruptions or price peaks,” Frischknecht said.
With our high investment in rooftop solar, and prospects for batteries, Zibelman sees no reason why demand response cannot grow to be at least 30 per cent of the Australian market.
- A new contract signed by a utility in Arizona has set a new low price for large-scale solar power in that country, but more importantly has also smashed expectations of the combined cost of large-scale solar and battery storage.
Tucson Electric Power (TEP) this week announced it would buy solar energy from a new 100MW solar plant at the historically low price of less than US3c/kWh – less than half of what it had agreed to pay in similar contracts over the last few years.
The project will also include 30MW/120MWh of battery storage, and the company says that the power purchase agreement for the combined output is “significantly less” than US4.5c/kWh – nearly two-thirds cheaper than the previous such contract struck in Hawaii, and well below the cost of a gas-fired peaking plant.
- The development is significant because it is confirmation that dispatchable renewable energy can compete with peaking gas-fired generators on price.
In Europe as prices plummet, offshore wind is now competitive with nuclear power, and gas is ‘in sight’.
Reputex has found that by taking aggressive regulatory action the government could meet its 2030 emissions reduction target without an Emissions Intensity Scheme (EIS) for the electricity sector.
- Energy productivity activities such as fuel efficiency standards for vehicles and industrial energy efficiency, can contribute around 43 per cent of Australia’s abatement task to meet the 2030 target, or 66Mt of emissions reductions in 2030.
These activities may be implemented at “negative cost” – providing a return over the lifetime of an investment.
Reputex do say, however:
- Ultimately, an EIS will be required to provide certainty to investors and support the decarbonisation of the economy in line with a 1.5- to 2-degree target under the Paris Agreement.
It’s just that we don’t need an EIS to get well down the track.
Spain went to the market for 3GW of renewable energy and awarded the vast majority to onshore wind at a record low price of €43 per megawatt-hour (MWh).
The German auction was for onshore wind energy which yielded “a pleasingly high level of competition” and was significantly oversubscribed.In all 256 bids with a volume of 2,137 MW were received. 70 bids totalling 807 MW were accepted, at an average of €57.1 MW/h. A notable aspect was:
The auction was specifically interesting with 70% of all bids being submitted by citizens’ energy companies, receiving 93% of the bids and 96% of the volume awarded.
John Howard recently made an extraordinary statement about climate and clean energy policies:
- telling an audience in Perth about the “scandalous” clean energy policies in Australia and why the country should never have gone beyond his target of just 2 per cent renewable energy.
Giles Parkinson details how the apparent LNP enthusiasm for renewable energy before the 2013 election changed to outright hostility after the election. There has been an accommodation of the pro-fossil fuel, anti-climate change right wing of the party, along with rewriting history.
What we have now is mixed rhetoric from the Turnbull government, with some apparent enthusiasm for the work of ARENA, which Abbott tried to destroy, and for batteries etc. Little wonder many in the industry are confused. Short-term politics is the order of the day. Bernard Keane of Crikey this morning told how the Snowy Hydro 2.0 pumped storage initiative came out of the PMs office, and the Prime Minister’s Department was given a few days to turn it into an ‘announceable’ aimed at lifting Newspoll. The genesis of the banks levy and Inland Rail was similar.
Meanwhile we would do well to remember that electricity generation is responsible for only 35% of emissions (from Grattan):
However, renewables can have a large impact on transport and Direct combustion, in heating for example.
Irrespective of government policy, the industry is now moving strongly towards renewable energy. In Australia, national government policy is struggling to keep up. We look forward to Finkel.
