UK Electricity Part 3: Wind and Solar

Part 1 of the series on 2050 electricity demand provided a “high electrification” scenario where the average electricity demand was approximately 72GW, but peak demand on exceptionally cold days could reach 121GW.

Part 2 described how this demand could be fulfilled with a nuclear supply model. In Part 3 we have used the same demand model to show how this could be substantially fulfilled with wind and solar power; though relying on significant amounts of storage to match supply and demand, and gas (or biofuel) capacity to operate when storage is insufficient. A number of different scenarios are explored, with the preferred scenario laid out below, adjacent to the nuclear scenario for comparison. Continue reading

UK Electricity 2050 Part 2: A High Nuclear Model

Guest post by Energy Matters’ commentators Alex Terrell and Andy Dawson. In part 2 of their trilogy, Alex and Andy examine how the UK 2050 electricity demand may be met by a nuclear dominated supply model. It requires 85 GW of nuclear capacity in the UK. The model is founded on existing technology and existing UK nuclear sites. But as the decades pass goes on to include new UK nuclear sites previously occupied by coal fired power stations and clusters of small modular reactors (SMRS) that have yet to be built, licensed and tested. It concludes by introducing the concept of nuclear islands built in very shallow water off the English coast. Continue reading

UK Electricity 2050 Part 1: a demand model

Guest post by Energy Matters’ commentators Alex Terrel and Andy Dawson. Alex Terrell is a business consultant in the area of Vehicle Telematics. He has also consulted in Energy and Manufacturing, and has a degree in Engineering. Andy Dawson is an energy sector systems consultant and former nuclear engineer.

This lengthy post is in three parts and aims to provide greater sophistication to a UK 2050 electricity model than can be achieved using the DECC 2050 calculator. Part 1 (below) presents the demand model. Parts 2 and 3 (to follow) will look at how demand may be met by a high nuclear option and from a renewables option. Continue reading

The UK’s Small Modular Reactor Competition

The UK government has launched a competition to select a design of small modular reactor (SMR) for future deployment in the UK. The idea behind SMRs is that they can be factory built and stamped out like aircraft and transported to location on the back of a truck. With thirty-three companies / designs on the shortlist, this looks like the process could take a while to complete.

In this post, nuclear engineer Andy Dawson provides an overview of SMR technology together with descriptions of the leading contenders. Continue reading
