Fresh details have emerged surrounding UK-headquartered utility Centrica’s rumoured 100MW battery after a planning application was submitted to Kilkenny County Council in Ireland through a joint venture formed in part by local subsidiary Bord Gáis Energy.

What is thought to be the largest operating containerised vanadium redox flow machine system in the UK has been connected to the grid by manufacturer redT energy, with the 1MWh project becoming the first to sign up to a local energy market being set up by British multinational utility Centrica.

Centrica has completed the installation of a 3MW battery in the North-East of England for local authority Gateshead Council, which the multinational utility’s Distributed Energy and Power business has dubbed one of the country’s largest commercial battery storage schemes.

UK flow battery provider redT will deliver a 1.08MWh energy storage project to support the distributed energy system in Cornwall, England, and potentially take part in utility Centrica’s developing ‘virtual energy marketplace’.

Battery storage specialist Younicos has been selected by Centrica to design the 49MW battery storage project that was last week awarded a 15-year Capacity Market contract.
