BP added to its growing presence in the electricity sector with the acquisition of Blueprint Power, a US distributed technology start-up that aims to turn commercial buildings into 'virtual power plants' able to trade green energy and now plans major expansion under the supermajor's wing.

Blueprint said with BP’s help it hopes by the end of 2022 to almost triple to 36MW the aggregated generation capacity of buildings that use its cloud-based software and services based on advanced algorithms to flexibly manage and sell excess power they produce from on-site renewables such as PV modules.
