Quinbrook Infrastructure Partners has raised £620 million for a UK-focused renewables fund, with solar, storage and flexibility assets a key focus.

The level of investor commitments exceeded the initial £500 million target, Quinbrook said yesterday (2 October). It is the investment firm’s third managed fund and was marketed exclusively to UK institutional investors, it said.

The portfolio includes a range of assets with long-term inflation linked contracts with bankable counter-parties such as transmission system operator (TSO) National Grid and the UK Government. This includes the Pathfinder programme, the Contracts for Difference programme and the Capacity Market. Over 60% of the modelled portfolio is either operational or under construction.

This includes Cleve Hill, the largest solar and battery storage project in the UK which pairs 373MW of PV and a 150MW+ battery energy storage system (BESS), and the 230MW/460MWh Uskmouth BESS it acquired the project rights for last year.

The portfolio also includes five synchronous condenser units, one in Wales and four in Scotland, which provide grid stability services to National Grid.

On top of the projects, Quinbrook acquired battery energy storage system (BESS) optimisation firm Habitat Energy in 2021.
