National Grid plugs TagEnergy’s 100MW battery project in at its Drax substation. Following energisation, the facility in North Yorkshire is the UK’s largest transmission connected battery energy storage system (BESS). The facility is supporting Britain’s clean energy transition, and helping to ensure secure operation of the electricity system.
Traditionally National Grid carries out network reinforcements before a project plugs in – sometimes adding years to a connection – based on the assumption that batteries could charge at peak times and export when generation is high, exacerbating system peaks and constraints.
The UK’s 2023 Energy Act established an independent system planner and operator to help accelerate Great Britain’s energy transition; creating the National Energy System Operator (NESO).
A battery storage project developed by TagEnergy is now connected and energised on the electricity transmission network, following work by National Grid to plug the facility into its 132kV Drax substation in North Yorkshire.

A flexible resource is a resource that can adjust its output in the required timescale, in response to events caused by changes in renewable generation output or loads. Based on their physical locations in the power system, they can be classified as source-side, grid-side, load-side, and energy storage flexibility resources [7].
