My Lords, the Government work closely with Ofgem and National Grid to consider the outlook for generation capacity each winter. Ofgem’s report is valuable for aiding this process. The Government are taking the necessary steps to ensure that we have enough capacity to maintain a secure electricity supply at the most economic cost to the consumer. This will be achieved through new system balancing services in the short term, if Ofgem decides they are needed, and then through the capacity market. We have confirmed that we will initiate a capacity market in 2014 for delivery in 2018.
My Lords, I welcome the measures proposed in the Energy Bill to avoid future shortages of electricity supply. However, as my noble friend has pointed out, these measures cannot come into effect until 2018. Meanwhile, Ofgem, in its report of
My Lords, my noble friend raises a number of very important points. While I cannot answer for what the previous Government should have done, since 2010, the coalition Government have been
working closely with Ofgem and National Grid to address the security of supply as a very high priority. A significant amount of potential capacity is available through de-mothballed plant and demand-side response. The measures being consulted on by National Grid and Ofgem would, if used, enable the procurement of the amount of capacity needed to ensure security of supply, allowing them to respond accordingly.
My Lords, will the Minister confirm that in the middle of last December the lights virtually went out because there was no spare capacity at all, and if the weather had got a shade colder, the lights would have gone out? Is it not time that we made some clear decisions about our fuel supply in this country?
My Lords, the noble Lord is right that we need to make some secure decisions. That is why, through the Energy Bill, we are reforming the electricity market and also making sure that we have a greater diversity in the supply of energy. A key part of balancing the service is the short-term operating reserve that we already have. The National Grid aims to have around 1,800 megawatts of this reserve available every day across a number of contracts, so I can reassure the noble Lord that the lights will stay on.
My Lords, is the Minister aware that in Germany, CO2 emissions are rising very fast, they are burning more coal than ever, their solar industry has collapsed, and, of course, that they have banned any expansion or indeed any use of their nuclear power stations? Does she agree that that is not exactly an example that we want to follow? Is not the right course for us, as she herself has steadfastly urged, to get on and invest as fast as possible in new gas turbines and, in due course, when we can afford it, in new nuclear power?
My Lords, does the Minister agree that this situation has been brought about by the failure of successive Governments to invest adequately in alternative low-carbon forms of renewable energy, and also to invest in new nuclear? Will she now agree that it is absolutely essential that projects such as the Horizon project at Wylfa B in Anglesey should go ahead as soon as possible?
cautious pessimism. Are we moving towards cautious optimism or is it just stalemate, as it has been for the last year and a half?
As the noble Lord knows, I am a person of great optimism and the negotiations are ongoing. We should be optimistic about what this country can offer for nuclear and for renewables.
My Lords, reverting to the point of balance raised by the noble Lord, Lord Ezra, does my noble friend agree that it is far more important that we keep the lights on than that we achieve a European target at a specific time? Perhaps some installations that are mothballed ought to be taken out of mothballs.
No, my Lords, the path that the Government have taken is absolutely the right one. A number of plants are mothballed, but, as I said earlier, they can come on board if we require them. At this moment, we do not require them.
Did I hear the noble Baroness aright, when she said that the spare capacity was 1,800 megawatts? If so, that represents only 4% of maximum demand. When I worked in the electricity supply industry, we believed that we could not run the system with less than 18% spare capacity. If we are down to 4%, we are in a very serious position.
My Lords, I said that we already have 1,800 megawatts to draw on, but that Ofgem and National Grid are consulting on whether, in the short term, we need to procure more.
My Lords, is it not quite clear that the best way to solve any potential capacity crunch would be to focus on demand-side management and response? What has changed in our profile of electricity demand is that demand is now flat and falling. That can be encouraged with smart investment in strategies and policies that bring that forward at an even faster pace.
As the noble Baroness is aware— we are, of course, having rounded discussions through the Energy Bill—that is among the options we are looking at.
