Demand from gas-fired generation dropped in 2024 as a result of near-record levels of renewable generation, according to a report from Montel Analytics.

The report – GB electricity market summary – offers analysis and insights into Britain’s energy mix over 2024 by looking at the generation and contribution by fuel type.

Renewables were the dominant contributor, accounting for 44.8% of the total. Gas-fired generation accounted for 27.5%, with nuclear (14.5%), imports (12.6%) and coal (0.6%) making up the rest.

The main takeaway from the report is that output from gas-fired generation has reached its lowest level in at least 20 years. This reduced demand is the result of near-record levels of renewable generation and also significantly increased levels of electricity imports through the interconnectors, particularly from France and Norway.

The report findings show that gas-fired output is dropping year-on-year, with 72.6TWh recorded in 2024 – down from 86.8TWh in 2023 and 111.4TWh in 2022...
