Global investment management company Quinbrook Infrastructure Partners has announced the acquisition of a 350MW solar photovoltaic (PV) project known as Mallard Pass in the UK.

Situated on the Rutland-Lincolnshire border in the East Midlands, the project marks Quinbrook’s second nationally significant infrastructure project (NSIP) following the Cleve Hill Solar project, which is nearing the end of construction.

Construction of Mallard Pass is slated to begin in 2026, with the start of operations projected for 2028. Quinbrook plans to apply its expertise from the Cleve Hill project, a comparably sized initiative that is expected to start generating solar power this quarter.

Cleve Hill was the first NSIP to secure a contract for difference (CfD) in July 2022 as part of the UK’s Allocation Round 4.

In November 2024, Quinbrook disclosed that Cleve Hill had secured the UK’s largest-ever solar corporate power purchase agreement (PPA) with Tesco.

Quinbrook intends to focus on the local and regional benefits that Mallard Pass can offer, similar to its approach with Cleve Hill.

This includes providing employment opportunities for local residents during both the construction and operational phases.

An initial analysis suggests that Mallard Pass could support over two thousand direct and indirect jobs and contribute more than £124m to the local economy over its expected lifetime.

Mallard Pass is estimated to generate over 14 million megawatt-hours of renewable energy throughout its lifespan, potentially reducing CO₂ emissions by 665,000t.

Quinbrook also aims to achieve a 71% biodiversity net gain on the Mallard Pass site, building on the 67% biodiversity net gain realised at Cleve Hill. Quinbrook and affiliate Private Energy Partners will now move forward with the detailed design, procurement, and construction planning for Mallard Pass.
