At 40 MW, Fareham is the UK’s largest Battery Energy Storage System (BESS) that is owned by a local authority, and will be fully optimised by Limejump in the National Grid’s Dynamic Containment market in April 2022. An additional 20 MW of battery storage at Fareham will go live in the summer and will be optimised by Limejump as part of this partnership. The 30 MW Fideoak Mill site has been operational since 2020, Limejump took over optimisation of this asset in late 2021. Limejump is now optimising Fideoak across several markets including stacking Dynamic Containment with wholesale trades.
Limejump, which has been optimising batteries since 2016, will be utilising its experience gained from over 44,000 optimisation hours in the UK flexibility market to ensure SSDC Opium’s assets are in the right market at the most opportune time.
“As the UK looks to invest in and secure a more sustainable energy future, we’re working harder than ever to support the deployment of renewables and BESS across the UK” said Genna Boyle, Limejump’s Head of Renewables & Flexibility. “We are delighted to have entered an agreement to optimise SSDC Opium Power’s 90 MW portfolio. These storage projects, and the others on our platform, are providing resilience and much needed flexibility services to the grid at a particularly crucial and pivotal time for the UK energy system. Our agreement with SSDC Opium comes as the UK Government will soon unveil a new energy strategy, one that is focused on greater energy independence. We expect the Government to lift restrictions on onshore wind and take steps to facilitate more BESS and solar. National Grid ESO’s Leading the Way FES scenario in 2021 predicted up to 13.1 GW of BESS by 2030, so we have a real challenge ahead of us to achieve this.”
In July 2021, Limejump commenced the optimisation of the 100 MW Minety battery in Wiltshire, which is still the largest battery to be optimised in any of National Grid’s ancillary services.
