How reliable is a renewables-dominated electricity system?

On 24 October, Energy UK hosted a breakfast briefing with Vivid Economics on 'How reliable is a renewables-dominated electricity system?' Chairing this briefing, Kyle Martin was joined by panellists from Vivid Economics, National Grid, Reactive Technologies, and the Committee on Climate Change to discuss how much wind and solar can be integrated into the electricity mix while maintaining the reliability of the system.

We would like to thank Vivid Economics for their contribution.

The panellists explored decarbonisation, synchronous and non-synchronous power plants, the role of data in the integration of renewables onto the grid, regional inertia challenges and the impact to consumers if we reach a renewables-dominated electricity system.

Panellist, Eric Ling, Head of Electricity System Analysis at Vivid Economics presented the findings from their report, illustrating that steep decarbonisation of the UK power system is possible by 2030 without reliance on thermal power stations.

Beth Warnock, System Performance Manager at National Grid looked at the difference between synchronous and non-synchronous power plants and how these can both support the stability of the system.

Chris Kimmett, Commercial Director Networks at Reactive Technologies explored data’s role in the integration of renewables onto the grid.

Looking at system flexibility and regional inertia challenges, the Committee on Climate Change’s Power Sector Lead, Mike Hemsley explained how with more renewables on the grid, costs to the consumer could potentially be reduced, however, the scale of the challenges is still uncertain.
