How does Britain actually keep the electricity system balanced as we transition to renewable energy?

In this episode of Next Time Around, we’re joined by Victoria Moxham, Director of Customer and Code Management at Elexon, the organisation responsible for administering the Balancing and Settlement Code and settling Britain’s wholesale electricity market.

With more wind and solar entering the system, the grid is becoming increasingly complex. Flexibility, real-time data and smarter market rules are now essential to maintaining energy security, enabling decentralised generation and supporting the UK’s net zero transition.

Victoria explains how Elexon sits at the heart of the electricity market — comparing what generators and suppliers say they will produce or consume with what actually happens, and settling billions of pounds in energy trading every year.

We explore the growing importance of flexibility markets, the rollout of market-wide half-hourly settlement, and how better data and interoperability could unlock new opportunities for consumers, businesses, and technology providers across the energy ecosystem.

In this episode we cover:

• How Britain’s electricity market is balanced behind the scenes
• The role of Elexon in wholesale market settlement and grid stability
• Why flexibility is becoming central to the UK energy system
• The impact of market-wide half-hourly settlement (MHHS)
• How smart meters, EVs, batteries and AI could reshape electricity demand
• The importance of data, interoperability and governance in the future smart grid
• What it will take to deliver long-term energy security in a renewable-led system

As the electricity system evolves from centralised power stations to a more flexible, decentralised and data-driven grid, Victoria shares how the rules, technology and market structures are adapting to support the energy transition.
