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
