Jackson will join National Grid on July 1, and will assume duties in her new role on Sept. 1. She will also sit on the group's executive committee.

National Grid Ventures operates in Britain, Europe and the United States, developing and operating large-scale low-carbon infrastructure and renewables.

Jackson left Shell in June following a leadership reshuffle by CEO Wael Sawan.
