Penso Power adds 50MW to Europe’s largest battery scheme

Penso Power has secured land rights, planning permission and a grid connection offer to extend the 100MW Minety project by a further 50MW.

The Miney project, near Swindon, is Europe’s largest battery storage development and set to enter operation in the autumn. The extra 50MW capacity will be built on adjacent land, entering operation in 2021.

Penso noted the development of the project has been enabled through commercial agreements with Shell Energy Europe and Limejump, with Shell signing a major offtake agreement on the original 100MW project and Limejump to optimise and dispatch the batteries. It is now in discussion with potential offtakers regarding similar arrangements for the 50MW project extension. It explained that this offtake structure de-risks the returns for infrastructure investors while accessing deep and liquid markets to enable the development of battery storage at a very large scale. Scale benefits allow for the provision of a range of balancing services on a cost-effective basis.

CEO of Penso Power, Richard Thwaites, said: “Minety is a landmark project for UK battery storage. Its sheer size marks it as the most significant battery storage development in Europe so far, dwarfing other battery developments in scale and ambition.  It shows that storage will play a more substantial role in the UK energy market as we continue our path towards Net Zero.”
