The UK battery energy storage sector faces significant grid connection delays, with some projects waiting up to thirteen years. Meanwhile, the Scottish government has rapidly approved multiple large-scale sites, and new government funding aims to advance ultra-long duration storage technologies to support the national energy transition.
Grid Connection Queue Delays
Battery energy storage projects in Great Britain are experiencing severe grid connection delays, with some facing wait times of up to thirteen years. A recent report highlighted that this systemic bottleneck threatens to strand billions in capital and jeopardises extensive development pipelines for major operators.
Connections Reform And Pathways
The National Energy System Operator is currently coordinating a reformed transmission connection process to address these severe infrastructure challenges. Smaller distribution connected systems typically follow Engineering Recommendation processes with local distribution network operators, whilst larger transmission projects require extensive system studies and formal bilateral connection agreements.
Scottish Planning Approvals
In contrast to ongoing connection delays, the Scottish government recently granted planning permission for four large battery projects totalling 1.4 gigawatts in a single day. This rapid approval included two long duration facilities that secured vital revenue support through the national cap and floor investment scheme.
Ultra Long Duration Funding
The government also launched a twenty eight million pound challenge to develop new technologies capable of storing clean energy for over one hundred hours. This initiative focuses on advanced batteries and underground hydrogen storage to reduce reliance on gas and protect future consumers from price spikes.
