My question is to the Minister representing the Minister for Climate Change and Energy, Senator McAllister. For every 100 megawatts of installed coal-fired power station capacity, the production of electricity average is around 95 to 98 megawatts. For every 100 megawatts of installed solar and wind generation capacity, though, the actual production of electricity average is just 23 megawatts, with wind itself being just 21. This means that to achieve design capacity, more than four times the installed rated capacity is required—almost five times for wind. Minister, is this included in Labor's transition costs?

Thanks very much for the question, Senator Roberts. In terms of costings, we take the advice of the experts. We've had this conversation more than once, in fact, in the context of estimates and in other forums. AEMO works through a range of scenarios and configurations for the National Electricity Market and makes an assessment of the optimal pathway to meet our energy requirements at the optimal cost. They do consider, of course, the capacity factors of the different options that are available to us. There's actually quite a lot of work to do. The truth is that we inherited a mess in the energy system. When we came in, the average wholesale energy price was $286 a megawatt hour—

Minister McAllister, please resume your seat. Senator Roberts?

Point of order on relevance: standing order 72(3)(c) says that answers shall be directly relevant to each question. Can we get on to whether or not Labor is aware—

Senator Roberts, as I've reminded other senators in this place, make your point of order but don't follow it up with a statement. The minister is being directly relevant to the points of your question. Minister McAllister, please continue.

Thanks, President. As I was saying, we came to government with a lot of work to do because the previous government had 22 energy policies, all of which failed. None of them landed. During the period when they were in government, four gigawatts of dispatchable capacity left the system and only one came on. We actually need to take steps to sort that out, because the previous government was repeatedly warned by the market operator that a failure to deal with the impending closure of coal-fired power stations was going to cause a reliability problem. We have sought advice from the experts at the market operator to help us design the policy settings that will actually allow us to replace that exit in capacity. It's a lot more than anything that was ever delivered by the people opposite. The very great shame is that, for a person who I know seeks to represent people in Queensland, you show an odd lack of interest in the opportunities that come about as a consequence of making and facilitating these investments, which have the potential to bring jobs and new industry to the communities that you claim to care about.

Senator Roberts, first supplementary?

During morning and evening peak hours, for every 100 megawatts of installed solar and wind generation capacity, the actual production of electricity averages just 10 megawatts. This means that achieving design capacity requires 10 times the installed rated capacity. Minister, what impact does this massive additional cost have on solar and wind installation capital costs and on electricity prices?

Senator, your question actually omits a really important part of the advice that we received from the market operator. The advice that we received—and it's based on very significant economic modelling and engagement with a whole range of market participants and experts in the energy system—is that the optimal configuration of technology for a future grid involves renewables, firmed by storage, including batteries, and supplemented by gas. That's the plan that has been recommended to us, and the policy settings that we've put in place are designed to allow investment in those kinds of technologies to be brought forward.

As I indicated in my answer to your primary question, there is a problem because there was an extended period when the lack of certainty in the policy settings of the previous government meant that the necessary investment didn't take place, and we are taking steps to remedy that problem.

A modern coal-fired power station is expected to last 60 years. Solar panels and wind turbines are expected to last 12 to 15 years—at most, 20. Over the 60-year life of a coal-fired power plant, the combination of wind and solar cobbled together to replace a single coal plant will need to be replaced four times. Minister, when will Labor release its system cost of the 2050 grid system?

Jenny McAllister (NSW, Australian Labor Party, Minister for Emergency Management) Share this | Link to this | Hansard source

As the senator would know if he'd examined the Integrated System Plan, it does include a costing for the capital costs associated with building the grid out to 2050. So the answer is: it is released and updated on a regular basis by way of the Integrated System Plan. That's the basis on which we establish our policies to deal with the transition that's underway in the electricity system.

The truth is that it is underway, Senator Roberts. I know that that is a proposition you don't agree with, but in just two years we've seen a 25 per cent increase in our national grid in the cheapest and cleanest form of energy that there is, which is reliable renewables, and we've ticked off enough reliable renewables projects to power three million homes. Those things matter. Establishing a clear pathway for the electricity supply that's necessary to meet the needs of households and businesses is an absolute priority for this government and should be for every other government as well.
