Limejump secures battery storage optimisation agreement with SSDC Opium power

Press Release

Limejump, the energy tech platform wholly owned by Shell, has entered a commercial partnership with SSDC Opium Power to optimise and manage their 90MW of battery storage across two sites – at Fareham in Hampshire and Fideoak Mill, near Taunton in Somerset.

40MW Fareham

At 40MW, Fareham is the UK’s largest Battery Energy Storage System (BESS) that is owned by a local authority, and it is now being fully optimised by Limejump in the National Grid’s Dynamic Containment market. An additional 20MW of battery storage at Fareham will go live in the summer and will be optimised by Limejump as part of this partnership. The 30MW 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, who has been optimising batteries since 2016, will be utilising their 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. Their sophisticated forecasting combined with their automated scheduling optimisation will remotely bid and optimise SSDC Opium’s full BESS portfolio into wholesale power and ancillary service markets.

Genna Boyle, Limejump’s Head of Renewables & Flexibility said: “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. We are delighted to have entered an agreement to optimise SSDC Opium Power’s 90MW 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 13.1GW of BESS by 2030, so we have a real challenge ahead of us to achieve this”
Jason Dobson, Opium Power, said: “We are delighted that Phase 1 of SSDC Opium Power’s Hampshire BESS project is now live and we are looking forward to working with Limejump going forward to maximise the revenue income from this site that will help supplement and fund SSDC’s public services.”
In July 2021, Limejump commenced the optimisation of the 100MW Minety battery in Wiltshire, which is still the largest battery to be optimised in any of National Grid’s ancillary services.
