Voltalia strengthens its presence in Europe with the City’s green energy deal in the UK.

On November 18, 2020, the governing body of the Square Mile has signed a power purchase agreement with Voltalia to buy all the electricity produced by a new-build 95,000-panel solar farm in Dorset for 15 years.


The solar plant will have a total capacity of 49.9 megawatts – enough to power the equivalent of 15,000 homes – and will provide over half the City Corporation’s electricity, powering buildings including its historic Guildhall headquarters, three wholesale markets, and the Barbican arts center.

The City of London Corporation is the governing body of the Square Mile dedicated to a vibrant and thriving City, supporting a diverse and sustainable London.
