The overall goal of Annex 28 is to foster the role of Distributed Energy Storage (DES) and to better evaluate the potential storage capacities for the integration of renewables at an economical competitive level. For this the following measures are taken:

• Identifying current applications for distributed energy storages (DES) to integrate fluctuating renewable energy sources into energy systems
• Examining distributed energy storage systems and their properties (including mechanical, electro-chemical, thermal and chemical and biogas approaches)
• Reviewing storage properties requirements depending on the different renewable energy sources (wind, PV, solar thermal, …)
• Studying possible control and operation strategies for DES and technologies by smart grids
• Quantifying potential of DES systems for the integration of renewable energies based on the current final energy demand
• Developing guidelines for choosing the most suitable DES technology for the current application
• Promoting best practice and success stories examples
