It is understood that most of the projects will be new build, although existing stores may be refurbished.
The London plan follows a £250m spend on regeneration and training projects across the country. Tesco has previously built housing on two of its stores in west London.
A Tesco spokeswoman said: "Each scheme is tailored to the area. We work in partnership with local boroughs and the public sector and wanted to wait until the Greater London Authority had settled down before doing a scheme in London."
