UK Regulator Proposes Fee to Cut Grid Connection Queue

The UK's energy regulator, Ofgem, has published a consultation on a proposal to introduce an Oversubscribed Technologies Commitment Fee (OTCF) to manage the national grid connections queue. The move directly targets the Battery Energy Storage System (BESS) sector, where the queue is oversubscribed by approximately 61 gigawatts against a projected 2035 need. Ofgem is concerned that this oversubscription distorts network planning and could lead to consumers bearing £460 million in inefficient infrastructure costs for projects that never materialize.

The proposed fee would start at £3,000 per megawatt and escalate every six months to a maximum of £25,000/MW as long as the queue remains oversubscribed. The measure would impose a significant new financial obligation on the vast majority of BESS projects, as an estimated 89% currently have securities below the proposed initial threshold. The policy is designed to force developers to prove financial commitment and project viability earlier, which should clear the queue of speculative projects. The consultation closes on October 1, 2026, with a final decision expected later in the year.
