A new independent report, commissioned by Centrica, has revealed the extent of the power projects holding back the UK's energy security and creating risk around hitting net zero.

The report examined the UK’s existing queue for Transmission Entry Capacity (TEC) – the queue for connecting new projects to the transmission grid – and discovered that it is up to four times oversubscribed. Not only that, but this oversubscription has become significantly worse in the last few years.

It found that:

• There are currently 371GW of projects in the queue, enough to significantly improve the UK’s energy security.

• Around 114GW worth of projects have listed their connection date as before 202, but around 62GW of these projects are only in the scoping phase and developers may not even have secured land rights or applied for planning consent.

The report suggests that the oversubscribed queue, and longer wait for connections. has a damaging effect on the investments that could drive the UK’s energy transition and energy security.

Ofgem is exploring rule changes (CMP376) to address queue issues and is expected to decide these before 10 November. These rule changes would grant the ESO the ability to remove projects from the queue if they miss key milestones. Ofgem is currently considering whether to apply this rule change to just new projects entering the queue, or whether the rule change should also be applied to projects already in the queue.


When examining Ofgem's solutions, the newly published report estimated that applying the rule change to projects already in the queue could add an additional 12GW of green power to the system in the short-term, as space is created for those projects that are ready to progress. This would be a beneficial result for consumers, net zero targets, and energy security, as moving stalled projects out of the way would allow more renewables onto the system quicker. It also noted this benefit would not materialise if Ofgem opts to only apply the rule change to future projects and keep these phantom power projects in the queue.

Chris O'Shea, Centrica Group Chief Executive, said: "In recent years energy security has rightly moved up the agenda as countries look to secure supplies and drive the transition to net zero. That's why it defies belief that the queue for new, green energy connections is blocked by 'phantom' power projects. Not only do these 'developers' not have the money to develop, but many also don’t even have planning permission or land rights – they’re gambling that holding a space in the queue will make them rich.

"The system was created for a different time, when a small number of large projects were connected each year. Our current approach is not fit for purpose and needs urgent reform.

"Thankfully Ofgem has now recognised the need for action but every day we wait for action is costing consumers money. Urgently introducing an industry rule change and applying it to the current queue, so that existing phantom projects lose their place when they miss milestones, would show that Ofgem were helping to reduce costs for consumers, to drive the energy transition and to improve the UK's energy security."
