GB electricity grid sets new zero-carbon record

Britain’s electricity grid has been operated at just under 99% zero-carbon for a short period in a new record for the system.

The National Energy System Operator (NESO) also said gas had hit a historic low of 1.2% of the energy mix at both the transmission and distribution levels on the same day

The low-carbon record between 15:30 and 16:00 on 22 April beat the previous record of   97.7% set on 1 April 2025. Solar power also hit two maximum records in as many days, reaching 15.4 GW for the first time

Kayte O’Neill, Chief Operating Officer at NESO, said: “This world-leading zero-carbon record underlines the resilience of Britain’s national electricity system, which is again showing it can be run safely and securely on large quantities of homegrown renewables.

“Hitting 98.8% zero-carbon really shows what is possible, and I look forward to seeing if we can break the ultimate record of running Britain’s electricity grid entirely zero carbon in the months ahead.”
