Utility Scale
Battery Storage

The UK’s 2050 net-zero target is ambitious, but there needs to be a significant seachange in the harnessing of renewable energy. Now is the time for commercial investors to be part of our renewable future.

Estimates show renewable generated capacity will need to increase to almost 60% by 2030 if there is any prospect of meeting the 2050 target. Battery storage provides grid operators with the tools and flexibility to deal with this increased supply variability and meet demand.

Utility-scale battery storage capable of harnessing high generation periods, stored during low demand and capable of feeding into the grid when demand is high, will be critical to a sustainable, low-carbon renewable future.

Planning changes pave the way for investors to be part of the UK's energy future

The relaxation of planning regulation allows for storage projects above 50 MW in England and 350 MW in Wales to proceed without approval through the national planning regime. This is a significant change.

The introduction of a capacity market in the UK in 2020 has opened the auction process for private utility-scale battery storage and removed demand-side response (DSR) barriers.

The changes include reducing the Minimum Capacity Threshold from 2 MW to 1 MW. DSR will now apply to prequalify to bid for all the agreement lengths in the capacity market, provided they can demonstrate the relevant CAPEX threshold.
