Project Overview


E-Flex exists to demonstrate the commercial potential of vehicle-to-grid (V2G) in energy markets, and establish it as an essential component of the zero-carbon economy. It seeks to change the way we think about the relationship between vehicles and energy.

The project will use real-world testing and deployments to deliver concrete proof of the value of V2G in energy markets.

Led by Cisco, the project will demonstrate the role V2G can play in supporting the transition of energy demands from cities and energy services towards a zero-carbon future, and prove that EVs can generate revenue without negatively impacting user experience.

Nuvve will demonstrate our V2G technology, test new fleet types and customer use cases in a metropolis, influence emerging regulatory and policy frameworks, and contribute to overall market design.
