Great British Energy Bill

Debate between Bernard Jenkin and Gideon Amos

2nd reading
Thursday 5th September 2024 Commons Chamber

[Sir Bernard Jenkin]

The Minister shakes his head, but if we have shut down all that capacity—if we cannot generate the electricity ourselves—we will have to get it from other places. There are phenomena called wind droughts, which can go on for very long periods. What are we going to do when the wind turbines are not turning and the sun is not shining during a very cold spell in the middle of winter? We had one or two close scares this winter. The generating margin that we used to enjoy has gone. The great risk of accelerating the decarbonisation of the electricity system is that there will be more appeals for voluntary or compulsory restraint from industry, because industry is the hidden customer that is shut off when we are short of electricity, or we risk more brownouts or even blackouts. That not impossible, so where is the data that the Minister is placing so much confidence in that shows these forecasts to be wrong? I am not making them off my own bat—there are plenty of people out there making them.

That brings me to the final brief point I want to make. I understand the logic that the Minister explained in his letter to me.

[Mr Amos]

I am sure that a Member with the experience of the hon. Gentleman will know that Britain returned to being a net exporter of electricity last year, so assuming that there will be additional costs from importing electricity due to the transition to renewables simply does not stack up. Does he also recognise that when the sun does not shine and the wind does not blow, the tide still rises and falls twice a day, 365 days a year? A future resting on renewable energy is possible, and we need to have that ambition for the United Kingdom.

[Sir Bernard Jenkin]

I absolutely share that ambition, but the question is how quickly we can get there. At the moment, tidal power produces almost nothing as a proportion of our electricity requirement. It is also intermittent, by the way: four times a day, there is a period during which it does not generate anything and we need to replace that supply with other things. The real challenge is how we get to the objective that the hon. Gentleman and I share in a rational way that carries the British public with us. It is noticeable that what people are complaining about most is the price on their electricity bills. Today, the constraint costs, balancing costs, infrastructure costs and import costs that I mentioned make up perhaps 50% of domestic electricity bills. If that figure is wrong, let the Minister produce some figures of his own that explain what proportion of consumers’ bills arises from all those factors, because it is not explained. There is no transparency on our electricity bills.

On the hon. Gentleman’s point about the objective of decarbonisation, we are not going to get there at all if we lose the public—if the lights start browning out or going out, and we find that we cannot meet demand. To some extent, we are piling up that demand by decarbonising transport and other parts of the system, including decarbonising building heating through heat pumps. The demand for electricity will rise, but our capacity to produce it reliably at all hours and in all conditions is being reduced.

On the question of imports and exports, we might become a net exporter of electricity, but perhaps the hon. Gentleman can explain how the price at which we are exporting compares with the price at which we are importing. The difficulty is that we will be importing when the wind is not blowing or the sun is not shining, and it is likely that the wind will not be blowing across the entirety of the North sea, so we will be importing fossil fuel-generated power at a very high cost to compensate for the fact that we have got rid of our own gas production and gas-fired power stations. I am not sure that situation will be very good.

If the hon. Gentleman would look at the Arup report on the Tarchon interconnector, which will come into my constituency under the present plans, he will see that that interconnector will not actually contribute very much to security of supply, but will be used almost entirely to export when there is too much wind. It will export at below the strike price because there is too much wind and it will export at a loss, and the cost will finish up on the bills of the British consumer. So the British consumer is paying for all the investment, paying for the strike prices, paying for the infrastructure and then paying to subsidise the exports to the Germans, who will be the beneficiaries of all this investment.

I appeal to the Minister to just read the Arup report and look at this. That is why I asked about the offshore co-ordination support scheme work that has been done. I am not going to ask for the impossible and ask him to revive the OCSS, but I would like from him an assurance that the work ESO has done will not simply be thrown away and wasted. Please can he assure the House that that work will be incorporated into the spatial plan that ESO says it wants to produce? Some very interesting innovations came out of that work, but there was also a lot of work discrediting the long-term viability of Norwich to Tilbury and, looking on a different timeframe—in the longer term—that could produce a much more viable alternative than is currently on the table. There is still work to be done on that, but I have no doubt that Fintan Slye will want to do that work as part of his project for the Government.

I would like to know that the Minister is going to support the holistic approach to which the Secretary of State referred, because Norwich to Tilbury is certainly not the product of a strategic approach to electricity grid upgrading. We need a much more strategic approach, and I am looking for that from this Government, but it certainly will not come from this Bill.
