How could the Belgian gas supply deal affect the National Energy System Operator?
Guaranteed gas flow from Belgium may boost NESO's system resilience. The deal ensures that gas can flow through a connecting pipeline from Belgium to Great Britain, supporting UK energy flexibility. This supply is intended to ensure enough gas is available to run gas-fired power stations at full capacity during a high-impact stress event. While the arrangement is described as a 'belt-and-braces measure' and not a permanent fix, the guaranteed supply provides continuing security of supply benefits over the following four years. This increased operational security helps the National Energy System Operator maintain the resilience of the national energy system.

How it reaches National Energy System Operator
-
Belgium has agreed to supply gas to Great Britain via pipelines to support energy flexibility. This arrangement ensures gas flow through a connecting pipeline during potential high-impact stress events this winter. The deal requires adding 10p a month to bills to cover the cost of maintaining the pipeline compressors needed for quick gas flow.

The guaranteed gas flow helps address the immediate security of supply position for winter 2026/27 and provides continuing security of supply benefits over the following four years. This operational support enhances the resilience of the national energy system that the National Energy System Operator manages.

Why it matters
The security of gas supply is critical for the stability of the national energy system, especially as demand peaks remain high and gas-fired power generation is vital when renewable output is low. This deal is seen as an interim response to mounting risks to Britain’s gas security, which has been flagged by reports, including one from the National Energy System Operator, warning of an emerging risk in 2030.
However, the deal is not a permanent solution. Experts note that the agreement does not remove the need for further government measures, such as increased gas storage or more LNG terminals, to address enduring challenges in the medium and longer term.
