UK regulator Ofgem has launched a cap and floor investment support scheme to unlock funding for new Long Duration Electricity Storage (LDES).

Invinity Energy Systems has been given the green light to deploy a 20.7MWh vanadium redox flow battery system in the UK, the largest in the country.

“Short duration flexibility has a massive role to play in reducing the costs of the Great British energy system, saving £10 billion a year by 2050,” Duncan Stone said this morning at the Energy Storage Summit 2025 in the UK.

Europe’s energy storage industry and key stakeholders arrive in London for the 2025 Energy Storage Summit EU in just a few days.

Ofgem, the UK’s energy market regulator, is considering raising the minimum duration of technologies eligible for a long-duration energy storage (LDES) support scheme.

The UK has confirmed a new scheme aiming to stimulate investment in the country’s long-duration energy storage (LDES) sector.
