While bringing enormous benefits, the move to distributed and intermittent low carbon renewable generation creates challenges for our energy system. The deployment of battery storage facilitates the addition of renewable generation and can help defer or avoid the cost of expensive network upgrades.
Energy storage plays a key and growing role in ensuring the resilience of our electricity networks. Batteries provide a scalable solution that is unique in its ability to respond rapidly and proportionately to imbalances in electricity supply and demand.
Battery storage supports lower emissions, lower costs, and lower energy prices.

Penso Power is developing and deploying a substantial pipeline of large-scale battery energy storage projects in the UK, Italy and Australia. Penso Power creates value at each stage of a project’s lifetime, from project development, design, and deployment to post-construction operation.
Our ambitions are global, and we will continue to seek new opportunities in a range of markets including in Europe and developing markets where we believe there may be significant potential to make an impact.
We benefit from the support of our partners , a leading global maritime company involved in shipping, floating infrastructure, deepwater oil & gas production, and new sustainable technologies.

The Minety development in Wiltshire, UK was Europe’s largest operational battery storage project at the time of energisation, initially 100MW / 136MWh and 150MW / 266MWh when fully built.
Our Hams Hall project in North Warwickshire, UK will see a further step up in scale with 400MW of connection capacity and an approved design allowing for deployment of up to 2GWh of energy.
Our battery storage project pipeline currently exceeds 4GWh.
