M&S to install largest rooftop solar at distribution centre

Retailer Marks & Spencer is to install the UK’s largest single roof mounted solar panel array on its East Midlands distribution centre in Castle Donington. The project, which is expected to be completed in early 2015, is being worked on in partnership with Amber Infrastructure.

The solar PV system will span the site’s 900,000 sq ft roof and will generate more than 5,000MWh of electricity per year, enough to power 1,190 houses. The 24,272 PV panel structure will lower M&S’s carbon footprint by 48,000 tonnes over 20 years. The energy generated will be enough to make the fully automated distribution centre close to self-sufficient during daylight hours.

This is one of a number of onsite renewable projects set to be announced by M&S over the next 12 months, to help the retailer achieve its commitment of ensuring 50% of electricity used in its building operations comes from small scale renewable sources by 2020.

Amber Infrastructure will supply and install the 6.1MWp solar panel system. M&S has agreed a 20 year power purchase agreement to purchase all of the electricity generated by the solar PV system.
