Teesworks and Energy Optimisation Solutions (EOS) have reached an agreement that will see the latter build a battery energy storage system (BESS) at the Teesside freeport development.

Energy storage solutions provider EOS is currently finalising its application for planning permission for the BESS, which is planned for the south west corner of the Teesworks site. If permission is granted, construction of the battery storage facility is anticipated to take around 12 months.

Solar Power Portal received confirmation from Peter Walker, director of EOS, that the £62 million facility will be a 100MW system with 200MWh energy storage capacity.

It will join NatPower’s proposed 1GW BESS for the site announced in May, as well as other planned energy initiatives including blue and green hydrogen production plants.

Teesworks Limited chairman Chris Musgrave said: “This latest agreement will further enhance Teesworks’ credentials as a leading UK centre for the transition to Net Zero. Battery storage is an essential component in ensuring that energy needs can be met from renewable sources regardless of weather conditions.”

EOS director Peter Walker said: “We’re really looking forward to coming to Teesworks. With so much renewable energy development planned for the site, such a supportive environment and such an experienced team in charge, it makes for the ideal location for our next battery storage facility.”

EOS has several battery storage projects already underway in the UK. The energy storage solutions provider is backed by funding from Quinbrook Infrastructure Partners; the two are working together on a 230MW/460MWh BESS in Newport South Wales.

Development of the Welsh BESS is delivered by EOS and Quinbrook under their portfolio company Uskmouth Energy Storage (UES). E.ON came on board in March 2024.

In October 2023, Quinbrook raised a £620 million UK-focused renewables fund, as covered by our sister site, Energy-Storage.news. The investment manager has also notably funded the flagship 373MW Cleve Hill solar-plus-storage nationally significant infrastructure project (NSIP), which it acquired in 2021.

Cleve Hill, set to be completed later this year, will have “more than” 150MW of battery energy storage.
