Giles was a founding Director and main board member of British Solar Renewables which sourced, designed, and delivered over half a gigawatt of solar projects. BSR delivered the 2nd largest portfolio of UK PV, including projects on the UK Government estate, on some of the UK’s largest estates through to quirky sites on dirty landfill sites. This included the 3 largest subsidised PV projects operating in the UK. It was the most fully integrated of the major UK developers.
In January 2021, Conor McNally left Macquarie Bank to join Giles in their joint venture PV/Storage development business Evolution Power. Apart from Conor, all of the core team at Evolution Power worked with Giles at BSR. Evolution Power is funded by Helsinki based investment fund Korkia and is developing a multiple gigawatt project pipeline that includes several DCO scale projects.
