The UK’s “largest” solar and battery energy storage project, Cleve Hill Solar Park, has started construction, Quinbrook Infrastructure Partners confirmed.

The specialist global investment manager revealed the Kent-based project, which consists of 373MW of solar and “more than” 150MW of battery energy storage, is expected to be fully completed by the end of 2024.

Once complete, Cleve Hill Solar Park will consist of 880,000 solar panels and battery storage. It was granted development consent by the energy secretary in May 2020.

The £450 million solar park – a joint venture originally between Hive Energy and Wirsol before being acquired by Quinbrook in 2021 – was the first in the UK to be classed as a Nationally Significant Infrastructure Project (NSIP) due to its scale.


The project, which had been renamed to Project Fortress, was originally scheduled to be constructed in the second half of 2022. Throughout its lifetime, it has faced significant public opposition as well as an attempt by Swale Borough Council to get its development consent overturned.

“High energy prices, geopolitical instability and the UK’s ambitious net zero goals are bringing into focus the critical need to accelerate the building of the next generation of energy transition infrastructure in the UK,” said Rory Quinlan, co-founder and managing partner of Quinbrook.
