The United Kingdom’s energy regulator, Ofgem, is exploring interventions to manage significant strain on the electrical grid caused by an oversupply of connection requests. Initially, discussions focused on introducing commitment fees for data centers to prevent speculative projects from occupying scarce network capacity, noting that 315 data centers were awaiting connections.

This regulatory approach has expanded to include battery energy storage systems (BESS). Ofgem is consulting on an ‘Oversubscribed Technologies Commitment Fee’ (OTCF), which would require operators to provide financial security to maintain their position in the grid connection queue. Estimates suggest that if all current projects with connection offers were completed, capacity would exceed the 2030 clean power target by 14.8 GW.
