The next two videos will be about the City-Zen Virtual Power Plant (VPP) project in Amsterdam. This Amsterdam-based project is an example of energy storage at a community level. Fifty households have a battery in their houses and these batteries are connected to form a single pool of stored energy. Through the VPP, the participating households can share their (self-produced) energy in their ‘energy community’. On behalf of the households, the VPP also buys and sells energy on the energy market and it can support the grid in case of energy shortages. The VPP-project was initiated by Alliander, a net operator company in The Netherlands, in collaboration with a software company (Energy Exchange Enablers), and an energy provider, Greenspread. In the next video, you will meet Jan Willem Eising from Alliander, who is the project manager of the VPP-project. He will introduce the VPP and talk about its relation to sustainable energy.  He will also discuss the roles of citizens and other stakeholders in the project.
