Dorset to Keep the Lights on in London

The City of London's economic hub has used 'green electricity' since 2018. The area covered includes the Guildhall buildings and Barbican Arts Centre, as well as Billingsgate, Smithfield and Spitalfields markets. A £40m, 15-year deal has been signed with a subsidy-free French company, Voltalia, to take 50% of their required electricity from a 49 megawatt installation in the Dorset countryside (https://www.theguardian.com/business/2020/nov/18/city-of-london-buys-into-new-dorset-solar-farm-to-help-power-square-mile). Voltalia's project involves 95,000 solar panels and just shows what can be achieved in terms of switching from non-renewables. Dorset, however, is in South-west England and some distance from London. It's an interesting echo with the past, as much of the stone used to create important buildings in London came from Portland in Dorset. I just wonder whether closer installations would be more energy efficient?
