It’s been a dramatic start to 2021 for Britain’s electricity system, with record high prices recorded in both the nation's day ahead market and its Balancing Mechanism.
As low winds and cold temperatures began to tighten capacity on the grid, National Grid ESO - Britain's system operator - issued a number of Electricity Margin Notices (EMN). There have been six this winter already, a number not seen since 2008.
Following each of the most recent EMNs there has been a dramatic reaction in the day-ahead markets, with prices in the N2EX market hitting £1,500/MWh (US$2,051/MWh) on 13 January after the most recent notice was issued.
