Mallard Pass

A 350 MW solar PV project, set to deliver over 14 million MWh of renewable power over its lifespan.

Mallard Pass represents Quinbrook’s second nationally significant infrastructure project (NSIP) after Cleve Hill Solar, the UK’s first NSIP. Construction of Mallard Pass is expected to begin in 2026 with commencement of operations in 2028. Quinbrook will leverage its experience from the comparably sized Cleve Hill project, which commenced generation of solar power in 2025. Mallard Pass is estimated to produce over 14 million MWh of renewable power over its lifespan and reduce CO2 emissions by 665,000 tonnes, equivalent to CO2 emissions from 738,691,906 pounds of coal burned. Quinbrook also aims to deliver a 71% biodiversity net gain at Mallard Pass, combining natural capital enhancement and creation initiatives and leveraging its experience from implementing 67% biodiversity net gain at Cleve Hill.
