Electricity Supply: International Interconnectors

Debate between Lord Prior of Brampton and Lord Oxburgh

Thursday 26th January 2017 Lords Chamber

[Lord Prior of Brampton]

I do not think there will necessarily be any impact from Brexit on the interconnector market. We are committed to building another 7.7 gigawatts of capacity and, in the Budget of 2016, we increased that to an additional 9 gigawatts of capacity by 2021. We are going to increase the amount of electricity flowing both ways through the interconnector system.

[Lord Oxburgh (CB)]

My Lords, as the Minister is undoubtedly aware, last Tuesday, 17 January, we received nothing through our interconnectors. Wind and other renewables generation in the country made up 2% of our supply and the remainder came from gas, coal and nuclear. Does he agree that to keep the lights on and to ensure security of supply in the country, we must have a minimum amount of dispatchable generation which can meet that demand and, furthermore, that that dispatchable supply is likely to be gas with carbon capture and storage? I declare many non-pecuniary interests in carbon capture and storage.

[Lord Prior of Brampton]

My Lords, I have an app on my phone through which I can tell exactly where all the electricity is coming from at any time. That 2% from renewables is very low; obviously, the wind was not blowing that day. The noble Lord is absolutely right that our baseload is provided by gas, coal and nuclear and I assure him that, in its Winter Outlook Report of October 2016, the National Grid said that we had an electricity margin of 6.6%, compared to 5.1% for the same period last year. There are no current concerns about security of supply.
