The Challenge

BMW wanted to cut its carbon footprint by increasing its use of self- generated, renewable power. We provided a tailor-made solution through a fully funded Power Purchase Agreement.

The project covers 20,000 square metres and was designed to supply power to newly opened body shop production line where more than 1,000 robots are in operation. Not only did the sheer size of the job present a challenge, but we were also presented with a tight schedule to complete the project.

Our team had just a week and a half to mobilise and prepare ahead of the start date. Detailed site surveys were required, management and construction plans had to be drawn up and materials, which often require long lead times, had to be ordered and delivered from third party suppliers at short notice. Quick and effective work was required.


In order to guarantee that work began on time, we made use of our longstanding supply chain relationships which also helped the project to be completed ahead of schedule.

At least a dozen installers were on site every day over the three-month period to make sure each project deadline was met. They made sure that the first roughly 4,000 panels were fitted and up and running in just five weeks, two weeks faster than normal.


As part of what is now one of the largest roof mounted solar installations in the UK, the BMW plant which now saves a huge 1,480,000kg CO2 per year. It was also one of the first businesses to sign up to the Low Carbon Oxford Charter, an agreement which aimed to reduce the city’s carbon footprint by 30% by 2020.
