Pilots need to demonstrate innovative Battery Energy Storage Systems (BESS) and Hybrid Energy Storage Systems HESS solutions within the home, building, community and stand-alone and power grid connected together with TSO and/or DSO, including real-time data sharing and operation. At least 2 pilots, with different use cases (overall covering both BESS and HESS systems), should present interoperable solutions involving different types of BESS.

The project(s) should facilitate hybrid energy storage systems (HESS) reaching a similar interoperability and Plug-and-Play capabilities of a BESS with extended performance by using virtualization techniques. Hybrid energy storage systems can concern distributed sources of storage, such as EV Batteries, Home Batteries, or connection with the Heat Pumps.  Deployment and adoption of IoT standards and platforms for distributed storage systems (stationary and electric vehicles) in Europe and development of cost-effective and sustainable European distributed storage ecosystems and related business models are expected. For example:

• Access of third parties to the minimum necessary data to perform aggregation functions should be looked at-which type of data could be made available for 3rd parties.
• Common solution between different stakeholder groups and different brands of devices should be looked at (for example storage from Heat Pumps requires coordination with several brands, so as to come up with a possible cross brands and cross sector solution).
• HESS dimensioning methodology depending on the application and integration conditions, including the selection of different European manufacturers ESS to conform the HESS, connection architecture, and control. Aspects of competition to be considered (include different manufacturers).
• Validation of the HESS integration in a real environment, demonstrating an efficient energy management, and the benefits of the combined capability of the individual ESS.
• Framework for use of data that may be considered as personal data generated by natural persons under the GDPR.

The need for standard harmonization across industry sectors should be explored, along with legislation and demonstration of scalability and stimulation of spill-over effects, for example towards applications beyond road transport. Feedback mechanisms from the users should be envisaged to allow adaptation and optimisation of the technological and business approach to the particular use case. The Commission will make sure that projects benefit from SSH expertise through the cooperation in Bridge.
