This week on the Talking Energy Podcast, Rob Gross is joined by CEO of Elexon: Peter Stanley. Peter and Rob discuss the Market-wide Half-Hourly Settlement (MHHS) programme, a major UK energy market reform, led by Elexon and overseen by Ofgem, which mandates settling all electricity consumption in 30-minute intervals. They discuss how using actual smart meter data instead of estimates enables more accurate billing, supports net zero goals, and facilitates flexible, time-of-use tariffs to lower consumer costs.
