A total of 6,926 solar panels have been installed at the warehouse, around one-seventh of the 48,000-panel system that the companies expect to install across the Port of Liverpool.

Multinational energy company E.ON and the Peel Ports Group have started commercial operations at the first phase of a 25MW rooftop solar array at the Alexandra Dock warehouse, part of the Peel Ports Group’s operations in its home city of Liverpool.
A total of 6,926 solar panels have been installed at the warehouse, around one-seventh of the 48,000-panel system that the companies expect to install “across many more buildings at the Port of Liverpool”. In 2024, the Peel Ports Group said it expects the entire portfolio to be operational by mid-2026, although, at the time, the portfolio was said to have a total capacity of 31MW, which has since been downgraded.
Still, the facility will be the largest rooftop solar project in the UK, and is expected to meet around one-quarter of the Port of Liverpool’s annual electricity demands.
“By transforming our warehouse rooftops into clean energy assets, we’re taking practical, large-scale action to decarbonise a critical national gateway which enables regional trade and economic growth,” said Lewis MacIntyre, managing director of port services at the Peel Ports Group.
The project is the result of a 25-year agreement between the Peel Ports Group and E.ON, with the latter financing and delivering the project. The Peel Ports Group is aiming to meet half of its electricity demand with renewable energy by the end of the decade, and reach net-zero emissions across its operations by 2040.

Last year, Tom Hutchison, CEO of the Montrose Port Authority in Scotland, told our colleagues at PV Tech Premium that securing clean power is a priority for the UK’s port industry, and that the ultimate goal is to be involved in the generation of on-site clean electricity, rather than having to buy power from an external generator.
“It’s good that it’s a guaranteed green source from the grid, but going forward, in the future, it only makes sense if we manage to be a bit more autonomous, if you like, and start generating our own energy,” Hutchison said at the Clean Power 2030 Summits.
In the months since, a number of UK ports have made investments, and seen returns on these investments, in the clean energy space. Last July, the Portsmouth International Port reported that the installation of a rooftop solar project had cut its energy bills by almost £140,000, while in November, BW ESS announced plans to build a battery energy storage system (BESS) at the Marchwood Industrial Park in Southampton.
