Electricity Grid Upgrades

Debate between Bernard Jenkin and Tom Hayes

Tuesday 26th November 2024 Westminster Hall

[Sir Bernard Jenkin]

I accept that the present Government have inherited a planning system and a philosophy of upgrading the national grid that is out of date.

When we were in Government, we were very slow to recognise that such a big, strategic upgrade needed a proper strategy. We started moving towards holistic network design. We commissioned a report from Charles Banner KC to look at streamlining the planning process—I will come on to putting that streamlining in place—and I very much welcome that the Government have commissioned a spatial review of the entire network, which should have been done years ago. I think we were blind to the failings of the structure inherited from the Electricity Act 1989; we should have moved much sooner.

That report should make it easier for the Government to change the out-of-date policy of a presumption in favour of pylons, which we said in our manifesto that we would review. I am very happy for the Minister to blame the previous Government for the difficulties he is facing and to change the policy accordingly, but it will be very odd if he comes to the Dispatch Box to defend what the previous Government were doing, after what the hon. Member for Camborne and Redruth (Perran Moon) just said—but I suspect that that is what he will do.

I put this issue forward in a bipartisan manner. We should all be able to agree that the great grid upgrade is not going fast enough, and that we need to streamline the planning process and speed up delivery. However, we also need to mend our ideas about how we deliver it, because as I have said, undergrounding high voltage direct current cables is not only technically viable, but the most sensible and sustainable solution for the future of our entire energy network.

[Tom Hayes (Bournemouth East) (Lab)]

I would like to return to the hon. Member’s point about international comparisons and other countries nearby perhaps having a presumption in favour of overgrounding. I draw the House’s attention to the fact that Germany’s Opposition recently said that using overhead lines instead of digging underground could save the country €35 billion, and that the German political parties that previously, as part of Angela Merkel’s coalition, backed underground cables have now called for overhead lines to be given priority. Does the hon. Member agree that the picture is not quite so clearcut in mainland Europe?

[Sir Bernard Jenkin]

What is interesting about Germany is that its presumption was in favour of undergrounding, so the idea that that is a great big experiment and we do not know what it means is incorrect. There is plenty of expertise in Europe. When we look at cost comparisons between undergrounding and pylons, it also depends on the territory we are dealing with.

Our problem is lack of community consent, as Fintan Slye, the executive director of the National Energy System Operator, rightly says. It is a question of swings and roundabouts, but in the case of Norwich to Tilbury, the consequence of delays from trying to run roughshod over the very widespread and well-funded public opposition will be to put up the cost, which makes the cost of undergrounding advantageous over pylons. That is my point.

I am not necessarily disagreeing with the principle of what the hon. Member for Bournemouth East (Tom Hayes) says, but undergrounding DC cables has great advantages. The latest estimated cost of just one year’s delay for Norwich to Tilbury is four times more than the additional £1 billion cost of undergrounding HVDC— I hope the hon. Gentleman was listening to that: £4 billion a year for delay against £1 billion extra for DC undergrounding. I think that puts this into the field of a no-brainer. Why would we spend all that money fighting through the courts for a very unpopular scheme when we could save time and legal expense by going for a different method?

In the National Energy System Operator’s East Anglia network study, which was published earlier this year, undergrounding HVDC was set out as alternative option 8. The great advantage of undergrounding HVDC is that there will be far less public resistance. Moreover, as I have said, the planning procedures could be streamlined— as recommended to the Government recently by Charles Banner—to conform to the regime for installing new major water pipes. If we had the same planning regime for underground cables as we did for water pipes, we could speed up the process for undergrounding cables.

Underground HVDC offers a scalable, future-proof solution that can be delivered with far less environmental impact, with public support and much more quickly. Schemes without pylons that are already planned by National Grid—for example, in north-east England—are being delivered without public opposition or long delays, which seems to be an enormous advantage for the Government’s objective of decarbonising the grid. There is no comparable resistance from campaign groups, which is clear evidence that underground HVDC gets public support, making it a far more practical and feasible solution.
