- Field’s projects selected under the ‘minded-to’ decision represent 1.6 GW / 26.8 GWh of new storage capacity
- New projects will more than double the duration record for a lithium-ion battery storage site at 16-18 hours
- And enable the UK to use more homegrown renewable power, strengthen energy security, and reduce costs to billpayers.
London, Friday 26th June - Field, the pan-European energy storage company, has today had five projects included in Ofgem’s minded-to decision for its cap-and-floor mechanism for long duration energy storage. The combined 1.6 GW / 26.8 GWh of projects, which will all be built using lithium-ion battery technology, represent almost a third of the projects notified under the Ofgem scheme, which will now move to the next phase of consultation. The five projects are:
- New Deer in Northern Scotland, a 400 MW / 7,800 MWh project
- Netherton in Northern Scotland, a 400 MW / 7,000 MWh project
- Fyrish in Northern Scotland, a 200 MW / 3,500 MWh project
- Rigifa in Northern Scotland, a 200 MW / 3,900 MWh project
- Long Stratton in East Anglia, a 400 MW / 6,800 MWh project
Each of these projects are in late stage development, with construction scheduled to begin from late 2027. Ofgem has calculated that the five projects together will provide a £1.9 billion net benefit to the UK. This value will be delivered to consumers through reduced electricity system costs, which in turn will drive lower bills.
Today’s announcement will unlock significant investment in Britain to build a new generation of long duration storage for the UK’s electricity system, 40 years after the last such project - the Dinorwig pumped hydro storage plant in North Wales - opened. Field’s projects will deliver long duration battery storage at scale, storing electricity when renewable generation is abundant and releasing it back to the grid when demand is high.
Field’s five selected projects are deliberately located where they can provide the greatest value to the system: close to sources of renewable generation and behind increasing network constraints. They will help the UK make the most of its wind and solar resources, further reduce reliance on fossil fuels, and lower curtailment and balancing costs.
Each of these projects will provide between 16 and 18 hours of storage duration, representing a major milestone for the energy storage industry. This is the result of extensive improvements in lithium-ion technology, and more efficient optimisation of these assets.
Amit Gudka, CEO and co-founder of Field, said:
The UK's LDES Cap and Floor is a global landmark scheme, and we're proud to be part of it. Our 16–18 hour duration batteries will be among the longest duration in the world — and represent a significant step forward in solving the challenge of day-to-day shifting of electricity.
This 'minded to' decision is a major vote of confidence in our projects, and validates three years of hard work building the case for long duration battery storage. Field is committed to being a key partner to the government in meeting the Clean Power 2030 goals.”

Notes to editors
- Field develops, builds and operates the renewable energy infrastructure we need to reach net zero in the UK and Europe — starting with battery storage. Our battery storage sites provide clean energy when and where it’s needed most. This creates a more reliable, flexible and greener energy system that provides greater energy security and helps countries across Europe move on from expensive fossil fuels.
- Long Duration Electricity Storage (LDES) refers to storage assets capable of discharging continuously for at least eight hours under the Ofgem cap-and-floor scheme.
- Ofgem’s cap-and-floor model sets a minimum and maximum revenue level for supported projects. If revenues fall below the floor, the mechanism provides a top-up, whilst if revenues rise above the cap, the additional revenue is returned to consumers.
