Britain’s growing blackout fears have exposed the increasing strain on the country’s electricity grid. The National Energy System Operator (NESO), the body responsible for keeping Britain’s lights on, has been forced to request “emergency assistance” from the continent.

What does it say about the state of our energy network when crisis measures are needed before we have even reached the deep depths of winter? That’s when the electricity system will be pushed to its limits. NESO is tasked with keeping the supply stable by maintaining the grid’s frequency at a strict target of 50Hz. But keeping that balance is proving increasingly costly with a staggering £505million of billpayer money spent in September alone on so-called “balancing costs”.

NESO has stressed that the electricity system is secure but experts warn it is in a precarious state.

The grid operator on Wednesday paid a record £49million to turn wind farms off in areas with an oversupply of electricity, while paying gas plants to fire up where supplies were tight. These bottleneck costs, levied directly onto household energy bills, are expected to hit a staggering £3.2billion within the next year.

The issue stems from a lack of infrastructure with power lines and pylons not being built fast enough to move renewable energy from remote generation sites down to major demand hubs in the south.

This week is not the first time NESO has faced scrutiny. Regulator Ofgem confirmed it is examining NESO’s performance and pushing for urgent action to bring constraint costs down.

It comes after NESO appointed independent lawyers to investigate allegations that staff covered up system failures during a heatwave in late June. A whistleblower claimed control room staff were warned by senior bosses against leaving a paper trail of efforts to stabilise the grid, which reportedly came close to a blackout.

Tory and Reform MPs argue that the Government’s net zero drive has exacerbated the crisis. Wind and solar capacity has grown far faster than the physical power lines, batteries and backup systems required to support it which has forced the grid to pay generators to switch off rather than overload the network.

But energy experts are confident this is a temporary growing pain of outdated infrastructure playing catch-up, rather than a fatal flaw in renewable energy itself.
